Senior Fixed Rate Notes

Senior Floating Rate Notes

We expect to issue one or more series of the above-listed senior notes in aggregate principal amounts to be determined.

The senior fixed rate notes due                 , or the fixed rate notes, will bear interest commencing                 , 2023 at the rate of     % per annum, payable semiannually in arrears on              and              of each year, beginning on                 , 2024.

The senior floating rate notes due                 , or the floating rate notes, and together with the fixed rate notes, the notes, will bear interest commencing                 , 2023 at a floating rate per annum, equal to Compounded Daily SOFR (determined as provided under “Description of the Notes”), plus     % payable quarterly in arrears on                 ,                 ,                  and                  of each year, beginning on                 , 2023, subject to adjustments.

The notes will not be redeemable prior to maturity, except as set forth under “Description of the Notes—Redemption for Taxation Reasons,” and will not be subject to any sinking fund. The notes will be issued only in registered form in minimum denominations of U.S.$200,000 and integral multiples of U.S.$1,000 in excess thereof.

We have made an application to the Luxembourg Stock Exchange to list the notes on the official list of the Luxembourg Stock Exchange and for such notes to be admitted to trading on the Luxembourg Stock Exchange’s Euro MTF Market. The Luxembourg Stock Exchange’s Euro MTF Market is not a regulated market for the purposes of Directive 2014/65/EU. This prospectus supplement constitutes a prospectus for purposes of Part IV of the Luxembourg law on prospectuses for securities dated July 16, 2019.

This prospectus supplement does not constitute a prospectus for the purposes of Regulation (EU) 2017/1129 (the “Prospectus Regulation”) as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (the “EUWA”).

Investing in the notes involves risks. You should carefully consider the risk factors set forth in “Item 3. Key Information—Risk Factors” of our most recent annual report on Form 20-F filed with the U.S. Securities and Exchange Commission, or the SEC, and in the “Risk Factors” section beginning on page S-8 of this prospectus supplement before making any decision to invest in the notes.

Neither the SEC nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus supplement or the related prospectus. Any representation to the contrary is a criminal offense.

The notes of each series will be represented by one or more global certificates deposited with a custodian for, and registered in the name of a nominee of, The Depository Trust Company, or DTC. Beneficial interests in these global certificates will be shown on, and transfers thereof will be effected through, records maintained by DTC and its direct and indirect participants, including Euroclear Bank SA/NV, or Euroclear, and Clearstream Banking S.A., or Clearstream. Except as described in this prospectus supplement or the accompanying prospectus, notes in definitive certificated form will not be issued in exchange for global certificates.

It is expected that the notes will be delivered in book-entry form only, through the facilities of DTC and its participants, including Euroclear and Clearstream, on or about             , 2023.

Prospectus

S-i

The notes have not been and will not be registered under the Financial Instruments and Exchange Act of Japan, or the FIEA, and are subject to the Act on Special Measures Concerning Taxation of Japan, or the Special Taxation Measures Act. The notes may not be offered or sold in Japan, to any person resident in Japan, or to others for reoffering or resale directly or indirectly in Japan or to a person resident in Japan, for Japanese securities law purposes (including any corporation or other entity organized under the laws of Japan) except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the FIEA and any other applicable laws, regulations and governmental guidelines of Japan. In addition, the notes are not, as part of the distribution by the underwriters under the applicable underwriting agreement at any time, to be directly or indirectly offered or sold to, or for the benefit of, any person other than a beneficial owner that is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a person having a special relationship with the issuer of the notes as described in Article 6, Paragraph (4) of the Special Taxation Measures Act, or a specially-related person of the issuer or (ii) a Japanese financial institution, designated in Article 6, Paragraph (11) of the Special Taxation Measures Act. Notwithstanding the aforementioned restriction, pursuant to the Special Taxation Measures Act, SMBC Nikko Securities America, Inc., acting in its capacity as an underwriter, will be permitted to acquire or purchase, as part of the distribution under the underwriting agreement of the notes, the remainder of the notes from any of the other underwriters, where such other underwriter has failed to sell to subsequent purchasers all of the notes that it acquired or purchased from us in its capacity as an underwriter.

Interest payments on the notes will generally be subject to Japanese withholding tax unless it is established that the notes are held by or for the account of a beneficial owner that is (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the issuer, (ii) a Japanese financial institution designated in Article 6, Paragraph (11) of the Special Taxation Measures Act which complies with the requirement for tax exemption under that paragraph or (iii) a Japanese public corporation, a Japanese financial institution or a Japanese financial instruments business operator described in Article 3-3, Paragraph (6) of the Special Taxation Measures Act which complies with the requirement for tax exemption under that paragraph.

Interest payments on the notes to an individual resident of Japan, to a Japanese corporation (except as described in the preceding paragraph), or to an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the issuer will be subject to deduction in respect of Japanese income tax at a rate of 15.315% (15% on or after January 1, 2038) of the amount of such interest.

Representation by Investor upon Distribution

By subscribing to any notes, an investor will be deemed to have represented that it is a beneficial owner who is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a person having a special relationship with the issuer of the notes as described in Article 6, Paragraph (4) of the Special Taxation Measures Act or (ii) a Japanese financial institution, designated in Article 6, Paragraph (11) of the Special Taxation Measures Act.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS—The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area, or the EEA. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended, or MiFID II; or (ii) a customer within the meaning of Directive (EU) 2016/97, or the Insurance Distribution Directive, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended, or the PRIIPs Regulation, for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

S-ii

PROHIBITION OF SALES TO U.K. RETAIL INVESTORS—The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom, or the U.K. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the EUWA; (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000, as amended, or the FSMA, and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA. Consequently no key information document required by the PRIIPs Regulation as it forms part of domestic law by virtue of the EUWA, or the U.K. PRIIPs Regulation, for offering or selling the notes or otherwise making them available to retail investors in the U.K. has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the U.K. may be unlawful under the U.K. PRIIPs Regulation.

This prospectus supplement is being distributed only to and is directed only at persons located outside the U.K. or in the U.K. to (i) persons who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended, or the Financial Promotion Order; or (ii) high net worth entities falling within Article 49(2)(a) to (d) of the Financial Promotion Order; or (iii) persons to whom it may otherwise lawfully be communicated (all such persons together being referred to as “relevant persons”).

RISK FACTORS

Investing in the notes involves risks. You should consider carefully the risks relating to the notes described below, as well as the other information presented in, or incorporated by reference into, this prospectus supplement and the accompanying prospectus, before you decide whether to invest in the notes. If any of these risks actually occurs, our business, financial condition and results of operations could suffer, and the trading price and liquidity of the notes offered could decline, in which case you may lose all or part of your investment. The following does not describe all the risks of an investment in the notes. Prospective investors should consult their own financial and legal advisers about risks associated with investment in a particular series of notes and the suitability of investing in the notes in light of their particular circumstances.

This prospectus supplement and the accompanying prospectus also contain forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including the risks described below, elsewhere in this prospectus supplement and in “Item 3. Key Information—Risk Factors” of our annual report on Form 20-F for the fiscal year ended March 31, 2023.

Risks Related to the Notes

The notes will be structurally subordinated to indebtedness and other liabilities of our subsidiaries, including Sumitomo Mitsui Banking Corporation.

As a holding company, our assets consist primarily of equity in and loans to our subsidiaries, in particular SMBC, and our ability to make payments on the notes depends on our receipt of dividends, loan payments and other funds from such subsidiaries. If our subsidiaries’ financial conditions materially deteriorate, or under certain other conditions, we may not be able to receive such funds from our subsidiaries due to legal restrictions, including under the Banking Act of Japan, or the Banking Act, the Companies Act of Japan, or the Companies Act, and the Deposit Insurance Act or as a result of contractual obligations, including loss absorption requirements, applicable to such subsidiaries. Claims of holders of the notes will be structurally subordinated to claims of creditors of our subsidiaries. In addition, our right to participate in any distribution of assets of any subsidiary (and thus the ability of holders of the notes to benefit as our creditors from such distribution) in bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceedings will be junior to creditors of that subsidiary, except to the extent that we may be recognized as a creditor of those subsidiaries in such proceedings. Claims of creditors of our subsidiaries include substantial amounts of long-term debt, deposit liabilities of SMBC and other banking subsidiaries, short-term borrowings, obligations under derivative transactions, trade payables and lease obligations. As a result, holders of the notes may receive less than full payment in the event of our bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceeding, even though the claims of creditors of our subsidiaries may be satisfied in full.

The notes will be subject to loss absorption if we become subject to orderly resolution measures under the Deposit Insurance Act and Japanese insolvency laws. As a result, the value of the notes could be materially adversely affected, and holders of the notes may lose all or a portion of their investment.

In November 2015, the Financial Stability Board, or the FSB, published its final Total Loss-Absorbing Capacity standards, or the TLAC standards. The final TLAC standards define certain minimum requirements for instruments and liabilities so that if a global systemically important bank, or G-SIB, fails, it will have sufficient loss absorbing and recapitalization capacity available in resolution. For more information regarding the FSB’s final TLAC standards, see “Item 4. Information on the Company—4.B. Business Overview—Regulations in Japan—Regulations Regarding Capital Adequacy and Liquidity—Capital Adequacy Requirement” in our annual report on Form 20-F for the fiscal year ended March 31, 2023, which is incorporated by reference herein.

In March 2019, the FSA published its public ministerial announcements, regulatory guidelines and related documents for the implementation of the TLAC standards in Japan, which we refer to herein as the Japanese

S-8

TLAC Standards. The Japanese TLAC Standards apply to Covered SIBs, which includes (i) Japanese G-SIBs, such as us, which are designated as G-SIBs by the FSA in accordance with the designation by the FSB, and (ii) any domestic systemically important bank in Japan, or Japanese D-SIB, that has been deemed to be in particular need for a cross-border resolution arrangement and as having particular systemic significance to the Japanese financial system if it fails. The Japanese TLAC Standards have applied to Japanese G-SIBs from March 31, 2019.

Under the FSB’s TLAC standards and the Japanese TLAC Standards, entities designated by the FSA as entities that would enter into domestic resolution proceedings for Japanese G-SIBs, or the Domestic Resolution Entities, are required:

In our case, the FSA designated SMFG as our Domestic Resolution Entity, which makes SMFG subject to the external TLAC requirements. The FSA also designated SMBC and SMBC Nikko Securities as our material subsidiaries in Japan, for which we are required to maintain a certain level of internal TLAC.

Under the Japanese TLAC Standards, unsecured senior debt issued by Japanese G-SIBs is not required to have any contractual write-down, write-off or conversion provisions in order to qualify as external TLAC instruments. In addition, unsecured senior debt issued by a Japanese G-SIB is not required to be contractually subordinated in order to qualify as external TLAC instruments, provided that the amount of excluded liabilities (as defined in the Japanese TLAC Standards) of such Japanese G-SIB which rank pari passu or junior to its unsecured senior liabilities does not exceed 5% of its external TLAC and the Japanese G-SIB’s creditors are recognized by the FSA as structurally subordinated to the creditors of its subsidiaries and affiliates. We intend for the notes to qualify as external TLAC instruments on the basis of, among other things, their structural subordination.

We expect to use the proceeds of the offering to extend unsecured loans to SMBC, which is designated as one of our material subsidiaries in Japan, as internal TLAC. In accordance with the Japanese TLAC Standards, these loans are required to be contractually subordinated to the excluded liabilities as defined in the Japanese TLAC Standards and have contractual loss absorption provisions that will act to discharge or extinguish the loans or convert them into SMBC’s ordinary shares upon a determination by the FSA that SMBC is non-viable due to material deterioration of its financial condition after recognizing that its liabilities exceed or are likely to exceed its assets, or that it has suspended or is likely to suspend payment of its obligations.

The notes are expected to be subject to potential losses through our liquidation pursuant to court-administered insolvency proceedings following the application of the orderly resolution powers under the Deposit Insurance Act. The Deposit Insurance Act, as amended in March 2014, provides the framework for resolving financial institutions, including financial holding companies, such as us, and operating banks. Such framework includes measures that may be applied to a financial institution prior to its failure, although there is no assurance that such measures would be applied in any given situation, and orderly resolution measures for financial institutions that have already failed or are likely to fail. In the FSA’s explanatory paper entitled “The FSA’s Approach to Introduce the TLAC Framework,” which was published in April 2016 and revised in April

S-9

2018, the FSA has identified Single Point of Entry, or SPE, resolution, in which resolution powers are applied to the ultimate holding company of a banking group by a single national resolution authority, as the preferred strategy for resolving currently designated G-SIBs in Japan. Under a possible model for SPE resolution of Japanese G-SIBs described in the Japanese TLAC Standards, if, with respect to a material subsidiary of a Japanese G-SIB that is designated as systemically important by the FSA, the FSA issues to the Domestic Resolution Entity of the Japanese G-SIB an order concerning the restoration of financial soundness, including recapitalization of, and restoration of liquidity to, such material subsidiary, such material subsidiary’s internal TLAC instruments will be written down or, if applicable, converted into common shares in accordance with the applicable contractual loss-absorption provisions of such internal TLAC instruments. The FSA may issue such an order pursuant to Article 52-33, Paragraph 1 of the Banking Act upon its determination that the material subsidiary is non-viable due to a material deterioration in its financial condition after recognizing that its liabilities exceed or are likely to exceed its assets, or that it has suspended or is likely to suspend payment of its obligations.

Following the write-down or conversion into common shares of internal TLAC instruments of the relevant material subsidiary, the relevant Domestic Resolution Entity’s liabilities may exceed its assets or it may suspend payment of its obligations. Under the Deposit Insurance Act, if the Prime Minister recognizes that liabilities of a financial institution, including a currently designated Domestic Resolution Entity, exceed or are likely to exceed its assets, or that it has suspended or is likely to suspend payment of its obligations and further recognizes that the failure of such financial institution may cause significant disruption in the financial markets or other financial systems in Japan, following deliberation by Japan’s Financial Crisis Response Council, the Prime Minister may confirm that “Specified Item 2 Measures (tokutei dai nigo sochi)” should be applied to such financial institution. Any such confirmation by the Prime Minister triggers the non-viability loss absorption provisions of Basel III Additional Tier 1 and Tier 2 instruments issued by the financial institution, causing such instruments to be written down or, if applicable, converted into common shares. The failed financial institution shall also be placed under special supervision by, or if the Prime Minister so orders, under special control of, the DIC, in which case, pursuant to Article 126-5 of the Deposit Insurance Act, the DIC would have broad authority to supervise or control the failed financial institution’s business, assets and/or liabilities, including the transfer of its systemically important assets and liabilities (which we expect in the case of our orderly resolution would include the shares of SMBC and other of our material subsidiaries based on the Japanese TLAC Standards) to a bridge financial institution established as a subsidiary of the DIC or such other financial institution as the DIC may determine, the repayment of certain of its liabilities and ultimately the initiation of court-administered insolvency proceedings with respect to such financial institution, in each case in accordance with the Deposit Insurance Act and other relevant laws. See “Item 4. Information on the Company—4.B. Business Overview—Regulations in Japan—Regulations for Stabilizing the Financial System—Deposit Insurance System” in our annual report on Form 20-F for the fiscal year ended March 31, 2023, which is incorporated by reference herein. In addition, to facilitate that transfer, the Prime Minister can designate certain assets that will be transferred to a bridge financial institution or to such other financial institution as part of our orderly resolution to be subject to a prohibition on attachment pursuant to Article 126-16 of the Deposit Insurance Act.

To facilitate our orderly resolution under the Deposit Insurance Act and Japanese insolvency proceedings, each holder and the trustee acknowledge, consent and agree (a) for a period of 30 days from and including the date upon which the Prime Minister confirms that Specified Item 2 Measures (tokutei dai nigo sochi) should be applied to us, not to initiate any action to attach any assets, the attachment of which has been prohibited by designation of the Prime Minister pursuant to Article 126-16 of the Deposit Insurance Act (or any successor provision thereto) and (b) to any transfer of our assets (including shares of our subsidiaries) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act (or any successor provision thereto), including any such transfer made pursuant to the authority of the DIC to represent and manage and dispose of our assets under Article 126-5 of the Deposit Insurance Act (or any successor provision thereto). The above permission may be granted by a Japanese court in accordance with the Deposit Insurance Act if (i) we are under special supervision by, or under special control of, the DIC pursuant to

S-10

the Deposit Insurance Act and (ii) our liabilities exceed or are likely to exceed our assets, or we have suspended or are likely to suspend payment of our obligations.

If we become subject to orderly resolution procedures under the Deposit Insurance Act, there can be no assurance that the exercise of measures available to the Prime Minister, the DIC or the Japanese courts to prevent disruption to financial markets or other financial systems in Japan would not adversely affect the rights of holders of the notes or the value of any holder’s investment in the notes. For example, if the shares of our subsidiaries are transferred to a bridge financial institution or such other financial institution as determined by the DIC, we would only be entitled to receive consideration representing the fair value of such shares, which could be significantly less than the book value of such shares. As a result, the recovery value of our residual assets in court-administered insolvency proceedings after the exercise of orderly resolution measures by the DIC may not be sufficient to fully satisfy our liabilities, including our obligations under the notes. In addition, the value of assets subject to a prohibition of attachment may decline while such prohibition is in effect, and following such period, holders will be unable to attach any assets that have been transferred to a bridge financial institution or such other financial institution as part of our orderly resolution.

The circumstances surrounding or triggering orderly resolution are unpredictable.

The occurrence of orderly resolution under the Deposit Insurance Act is inherently unpredictable and depends on a number of factors that may be beyond our control. Under the current framework, the commencement of the orderly resolution process is dependent upon, among other things, a determination by the Prime Minister, following deliberation by Japan’s Financial Crisis Response Council, regarding our viability, or the viability of one or more of our subsidiaries, and the risk that any failure may cause significant disruption in the financial markets or other financial systems in Japan. Under the Japanese TLAC Standards, as a possible model of a resolution of Japanese G-SIBs under the SPE resolution strategy, the application of Specified Item 2 Measures (tokutei dai nigo sochi) to us may result from, among other things, a loan that we extended to, or an investment we made in, or any other internal TLAC of, SMBC or any of our other material subsidiaries that are designated as systemically important by the FSA or that are subject to TLAC requirements or similar requirements by the relevant foreign authorities, being subjected to loss absorption before the failure of such subsidiary, pursuant to the terms of such loan or investment or other internal TLAC or in accordance with applicable laws or regulations then in effect. However, according to the Japanese TLAC Standards, the actual measures to be taken with respect to a Japanese G-SIB shall be determined by the relevant authorities on a case-by-case basis after taking into consideration the Japanese G-SIB’s actual condition. In addition, the application of orderly resolution measures under the Deposit Insurance Act is untested and will be subject to interpretation and application by the relevant regulatory and supervisory authorities in Japan. Moreover, it is uncertain how the relevant authorities would determine that our liabilities exceed or are likely to exceed our assets, or we have suspended or are likely to suspend payment of our obligations, which determination is required to commence an orderly resolution, and it is possible that particular circumstances that seem similar may result in different outcomes. Our creditors, including holders of the notes, may encounter difficulty in challenging the application of orderly resolution measures to us.

It may be difficult to predict when, if at all, we may become subject to orderly resolution. Accordingly, the market value of the notes may not necessarily be evaluated in a similar manner as other types of senior securities. Any indication that we are approaching circumstances that could result in us becoming subject to orderly resolution can be expected to have an adverse effect on the market price and liquidity of the notes.

The notes are unsecured obligations.

The notes are unsecured obligations and repayment of the notes may be compromised if:

S-11

If any of these events occurs then our assets may be insufficient to pay amounts due on the notes.

The Indenture and the notes do not restrict our ability or the ability of our subsidiaries to pledge, dispose or securitize our assets, pay dividends, incur indebtedness or issue or repurchase securities, and provide holders with limited protection in the event of a change in control and other actions we may take that could adversely impact your investment in the notes.

The Indenture and the notes do not contain any financial covenants or restrictions on our ability, or the ability of our subsidiaries, to pledge assets to secure any indebtedness, securitize assets, pay dividends on our shares of common stock, incur or assume additional indebtedness or other liabilities or repurchase our outstanding securities. These or other actions by us could adversely affect our ability to pay amounts due on the notes. In addition, the Indenture and the notes do not contain any covenants or other provisions that afford more than limited protection to holders of the notes in the event of a change in control.

There is no prior market for the notes and, if a market develops, it may not be liquid.

The notes are new securities which may not be widely distributed and for which there is currently no active trading market. Although we have made an application to the Luxembourg Stock Exchange to list the notes on the official list of the Luxembourg Stock Exchange and for such notes to be admitted to trading on the Luxembourg Stock Exchange’s Euro MTF Market, there can be no assurance that any liquid market for the notes will ever develop or be maintained. The underwriters have advised us that they currently intend to make a market in the notes that they distribute. However, the underwriters have no obligation to make a market in the notes and they may stop at any time. Furthermore, there can be no assurance as to the liquidity of any market that may develop for the notes or the prices at which you will be able to sell your notes, if at all. Future trading prices of the notes will depend on many factors, including:

Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including the time remaining to the maturity of the notes; the outstanding amount of the notes; and the level, direction and volatility of market interest rates generally.

In addition, in the event that our obligations in connection with maintaining the listing of the notes on the Luxembourg Stock Exchange become unduly burdensome, we may be entitled to, and may decide to, delist the notes from such securities exchange and seek an alternate listing for the notes on another securities exchange.

The ratings of the notes may change after issuance of the notes, and those changes may have an adverse effect on the market prices and liquidity of the notes.

The notes are expected to receive a credit rating from one or more credit rating agencies. Such ratings are limited in scope, and do not address all material risks relating to an investment in the notes, but reflect only the view of each rating agency at the time the rating is issued. There is no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn

S-12

entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Ratings may be affected by a number of factors which can change over time, including the credit rating agency’s assessment of: the issuer’s strategy and management’s capability; the issuer’s financial condition including in respect of capital, funding and liquidity; competitive and economic conditions in the issuer’s key markets; the level of political support for the industries in which the issuer operates; and legal and regulatory frameworks affecting the issuer’s legal structure, business activities and the rights of its creditors. The credit rating agencies may also revise the ratings methodologies applicable to issuers within a particular industry, or political or economic region. If credit rating agencies perceive there to be adverse changes in the factors affecting an issuer’s credit rating, including by virtue of changes to applicable ratings methodologies, the credit rating agencies may downgrade, suspend or withdraw the ratings assigned to an issuer and/or its securities. In particular, Fitch Ratings Japan Limited downgraded the long-term credit ratings of us and SMBC in December 2022 by one-notch from A to A-.

A downgrade or potential downgrade in these ratings or the assignment of new ratings that are lower than existing ratings could reduce the number of potential investors in the notes and adversely affect the prices and liquidity of the notes. A security rating is not a recommendation to buy, sell or hold the notes and may be subject to suspension, reduction or withdrawal at any time by the assigning rating agency.

The composition and characteristics of SOFR are not the same as those of U.S. dollar LIBOR, and SOFR is not expected to be a comparable replacement for U.S. dollar LIBOR.

In June 2017, the Federal Reserve Bank of New York (the “FRBNY”)’s Alternative Reference Rates Committee (the “ARRC”) announced SOFR as its recommended alternative to U.S. dollar LIBOR. However, the composition and characteristics of SOFR are not the same as those of U.S. dollar LIBOR. SOFR is a broad Treasury repurchase financing rate that represents overnight secured funding transactions and is not the economic equivalent of U.S. dollar LIBOR. While SOFR is a secured rate, U.S. dollar LIBOR was an unsecured rate. And, while SOFR is an overnight rate, U.S. dollar LIBOR was a forward-looking rate that represented interbank funding for a specified term. As a result, there can be no assurance that SOFR will perform in the same way as U.S. dollar LIBOR would have at any time, including, without limitation, as a result of changes in interest and yield rates in the market, bank credit risk, market volatility or global or regional economic, financial, political, regulatory, judicial or other events.

SOFR has a limited history, and the future performance of SOFR cannot be predicted based on historical performance.

The publication of SOFR began in April 2018, and, therefore, it has a limited history. In addition, the future performance of SOFR cannot be predicted based on the limited historical performance. Prior observed patterns, if any, in the behavior of market variables and their relation to SOFR, such as correlations, may change in the future. While some pre-publication historical data have been released by the FRBNY, such historical indicative data inherently involves assumptions, estimates and approximations. The future performance of SOFR is impossible to predict and therefore no future performance of SOFR may be inferred from any of the historical actual or historical indicative data. Hypothetical or historical performance data are not indicative of, and have no bearing on, the potential performance of SOFR. There can be no assurance that SOFR or Compounded Daily SOFR will be positive.

SOFR may be more volatile than other benchmark or market rates.

Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in other benchmark or market rates, such as three-month U.S. dollar LIBOR, during corresponding periods, and SOFR may bear little or no relation to the historical actual or historical indicative data. In addition, although changes in Compounded Daily SOFR generally are not expected to be as volatile as changes in daily levels of SOFR, the return on and value of the floating rate notes may fluctuate more than floating rate securities that are linked to less volatile rates.

S-13

Any failure of SOFR to maintain market acceptance could adversely affect the floating rate notes.

According to the ARRC, SOFR was developed for use in certain U.S. dollar derivatives and other financial contracts as an alternative to U.S. dollar LIBOR in part because it is considered a good representation of general funding conditions in the overnight U.S. Treasury repurchase agreement market. However, as a rate based on transactions secured by U.S. Treasury securities, it does not measure bank-specific credit risk and, as a result, is less likely to correlate with the unsecured short-term funding costs of banks. This may mean that market participants would not consider SOFR a suitable replacement or successor for all of the purposes for which U.S. dollar LIBOR historically was used (including, without limitation, as a representation of the unsecured short-term funding costs of banks), which may, in turn, lessen market acceptance of SOFR. Any failure of SOFR to maintain market acceptance could adversely affect the return on and value of the floating rate notes and the price at which investors can sell the floating rate notes in the secondary market.

The interest rate on the floating rate notes is based on a compounded SOFR rate, which is relatively new in the marketplace.

For each Interest Period (as defined below), the interest rate on the floating rate notes is based on Compounded Daily SOFR, which is calculated using the specific formula described under “Description of the Notes—Principal, Maturity and Interest for the Floating Rate Notes—Compounded Daily SOFR,” not the SOFR rate published on or in respect of a particular date during such Interest Period or an arithmetic average of SOFR rates during such period. For this and other reasons, the interest rate on the floating rate notes during any Interest Period will not be the same as the interest rate on other SOFR-linked investments that use an alternative basis to determine the applicable interest rate. Further, if the SOFR rate in respect of a particular date during the SOFR Observation Period for an Interest Period is negative, its contribution to Compounded Daily SOFR will be less than one, resulting in a reduction to Compounded Daily SOFR used to calculate the interest payable on the floating rate notes on the Interest Payment Date (as defined below) for such Interest Period.

In addition, limited market precedents exist for securities that use SOFR as the interest rate and the method for calculating an interest rate based upon SOFR in those precedents varies. Accordingly, the specific formula for the Compounded Daily SOFR rate used in the floating rate notes may not be widely adopted by other market participants, if at all. If the market adopts a different calculation method, that would likely adversely affect the market value of the floating rate notes. We may in the future also issue notes referencing SOFR that differ in terms of interest determination from the floating rate notes.

Compounded Daily SOFR with respect to a particular Interest Period will only be capable of being determined near the end of the relevant Interest Period.

The level of Compounded Daily SOFR applicable to a particular Interest Period and, therefore, the amount of interest payable with respect to such Interest Period will be determined on the Interest Determination Date (as defined below) for such Interest Period. Because each such date is near the end of such Interest Period, you will not know the amount of interest payable with respect to a particular Interest Period until shortly prior to the relevant Interest Payment Date and it may be difficult for you to reliably estimate the amount of interest that will be payable on each such Interest Payment Date. In addition, some investors may be unwilling or unable to trade the floating rate notes without changes to their information technology systems, both of which could adversely impact the liquidity and trading price of the floating rate notes.

The secondary trading market for securities linked to SOFR may be limited.

Since SOFR is a relatively new market rate, the floating rate notes may have no established trading market when issued, and an established trading market may never develop or may not be very liquid. If SOFR does not prove to be widely used as a benchmark in securities that are similar or comparable to the floating rate notes, the trading price of the floating rate notes may be lower than those of securities that are linked to rates that are more

S-14

widely used. Similarly, market terms for securities that are linked to SOFR, including, but not limited to, the spread over the reference rate reflected in the interest rate provisions, may evolve over time, and as a result, trading prices of the floating rate notes may be lower than those of later-issued securities that are based on SOFR. Investors in the floating rate notes may not be able to sell the floating rate notes at all or may not be able to sell the floating rate notes at prices that will provide them with a yield comparable to similar investments that have a developed secondary market, and may consequently suffer from increased pricing volatility and market risk.

SOFR may be modified or discontinued and the floating rate notes may bear interest by reference to a rate other than Compounded Daily SOFR, which could adversely affect the value of the floating rate notes.

SOFR is a relatively new rate, and the FRBNY (or a successor), as administrator of SOFR, may make methodological or other changes that could change the value of SOFR, including changes related to the method by which SOFR is calculated, eligibility criteria applicable to the transactions used to calculate SOFR, or timing related to the publication of SOFR. If the manner in which SOFR is calculated is changed, that change may result in a reduction of the amount of interest payable on the floating rate notes, which may adversely affect the trading prices of the floating rate notes. The administrator of SOFR may withdraw, modify, amend, suspend or discontinue the calculation or dissemination of SOFR in its sole discretion and without notice (in which case a fallback method of determining the interest rate on the floating rate notes as further described under “Description of the Notes—Principal, Maturity and Interest for the Floating Rate Notes—Benchmark Transition” will apply) and has no obligation to consider the interests of holders of the floating rate notes in calculating, withdrawing, modifying, amending, suspending or discontinuing SOFR.

If we or our designee determine that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred in respect of SOFR, then the interest rate on the floating rate notes will no longer be determined by reference to SOFR, but instead will be determined by reference to a different rate, which will be a different benchmark than SOFR, plus a spread adjustment, which we refer to as a “Benchmark Replacement,” as further described under “Description of the Notes—Principal, Maturity and Interest for the Floating Rate Notes—Benchmark Transition.”

If a particular Benchmark Replacement or Benchmark Replacement Adjustment cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected, recommended or formulated by (i) the Relevant Governmental Body (such as the ARRC), (ii) the International Swaps and Derivatives Association, Inc. (“ISDA”) or (iii) in certain circumstances, we or our designee. In addition, the terms of the floating rate notes expressly authorize us or our designee to make Benchmark Replacement Conforming Changes with respect to, among other things, changes to the definition of “Interest Period,” the timing and frequency of determining rates and making payments of interest and other administrative matters. The determination of a Benchmark Replacement, the calculation of the interest rate on the floating rate notes by reference to a Benchmark Replacement (including the application of a Benchmark Replacement Adjustment), any implementation of Benchmark Replacement Conforming Changes and any other determinations, decisions or elections that may be made under the terms of the floating rate notes in connection with a Benchmark Transition Event, could adversely affect the value of the floating rate notes, the return on the floating rate notes and the price at which you can sell such floating rate notes.

Any determination, decision or election described above will be made in the sole discretion of us or our designee. Any exercise of such discretion by us may present us with a conflict of interest. In addition, if we appoint an affiliate as our designee, any exercise of such discretion may present us or such affiliate with a conflict of interest.

In addition, (i) the composition and characteristics of the Benchmark Replacement will not be the same as those of SOFR, the Benchmark Replacement may not be the economic equivalent of SOFR, there can be no assurance that the Benchmark Replacement will perform in the same way as SOFR would have at any time and

S-15

there is no guarantee that the Benchmark Replacement will be a comparable substitute for SOFR (each of which means that a Benchmark Transition Event could adversely affect the value of the floating rate notes, the return on the floating rate notes and the price at which you can sell the floating rate notes), (ii) any failure of the Benchmark Replacement to gain market acceptance could adversely affect the floating rate notes, (iii) the Benchmark Replacement may have a limited history and the future performance of the Benchmark Replacement cannot be predicted based on historical performance, (iv) the secondary trading market for floating rate notes linked to the Benchmark Replacement may be limited and (v) the administrator of the Benchmark Replacement may make changes that could change the value of the Benchmark Replacement or discontinue the Benchmark Replacement and has no obligation to consider your interests in doing so.

We or our affiliates may participate in press activities or publish research that could affect the market value of the floating rate notes.

We or one or more of our affiliates may, at present or in the future, participate in press activities or publish research reports with respect to movements in interest rates generally, or with respect to the LIBOR transition to alternative reference rates or SOFR specifically. Such press activities or research may be modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding the floating rate notes. Any of these activities may affect the market value of the floating rate notes.

We or our designee may make determinations with respect to the floating rate notes.

We or our designee may make certain determinations with respect to the floating rate notes as further described under “Description of the Notes.” If a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, we or our designee will have the right to make certain determinations with respect to the floating rate notes in our or our designee’s sole discretion as further described under “Description of the Notes—Principal, Maturity and Interest for the Floating Rate Notes—Benchmark Transition.” Any of these determinations may adversely affect the value of the floating rate notes, the return on the floating rate notes and the price at which you can sell such floating rate notes. Moreover, certain determinations may require the exercise of discretion and the making of subjective judgments, such as with respect to Compounded Daily SOFR or the occurrence or non-occurrence of a Benchmark Transition Event and any Benchmark Replacement Conforming Changes. These potentially subjective determinations may adversely affect the value of the floating rate notes, the return on the floating rate notes and the price at which you can sell such floating rate notes. For further information regarding these types of determinations, see “Description of the Notes—Principal, Maturity and Interest for the Floating Rate Notes.”

USE OF PROCEEDS

We estimate that the net proceeds (after deducting underwriting commissions and estimated offering expenses) from the sale of the notes will be approximately $                 million. We intend to use the net proceeds of this offering to extend unsecured loans, intended to qualify as internal TLAC, to SMBC. SMBC intends to use the proceeds of the loans for general corporate purposes.

SMBC’s Bond Portfolio

SMBC’s bond portfolio is principally held for ALM purposes, with a small number of securities being held for inventory purposes for sales to customers. Most of SMBC’s bond portfolio is comprised of fixed-rate Japanese and local government bonds and high quality corporate bonds denominated in yen. On a non-consolidated basis, the approximate average duration of SMBC’s yen-denominated bond portfolio, including Japanese government bonds, or JGBs, but excluding private placement bonds, bonds held-to-maturity and bonds for which fair value hedge accounting is applied, was 2.8 years and 2.4 years as of March 31, 2022 and 2023, respectively. Bonds are also held to enhance liquidity, and, when needed, they can be used as collateral for call money or other money market funding or short-term borrowing from the Bank of Japan, or the BOJ. Sales of bonds are made from time to time in order to recognize discretionary gains. SMBC’s Treasury Department actively monitors the interest rate and maturity profile of its bond portfolio as part of our overall risk management.

DESCRIPTION OF THE NOTES

The following description of the notes supplements and, to the extent inconsistent therewith, replaces the description of the general terms and provisions of our senior debt securities set forth in the accompanying prospectus under the heading “Description of the Debt Securities.” It is important for you to consider the information contained in this prospectus supplement and in the accompanying prospectus and any applicable pricing term sheet in making your investment decision with respect to the notes. Whenever a defined term is referred to but not defined in this section, the definition of that term is contained in the accompanying prospectus or in the Indenture.

General

The notes will constitute senior debt securities to be issued under a senior indenture between us and The Bank of New York Mellon, as trustee, dated as of March 9, 2016, or the Base Indenture, as supplemented by the First Supplemental Indenture dated as of July 16, 2019 between us and The Bank of New York Mellon, as trustee, together with the Base Indenture, the Indenture. The Indenture is qualified under the U.S. Trust Indenture Act of 1939, as amended. The Indenture is more fully described in the accompanying prospectus. Copies of the Indenture and any amendments or supplements thereto will be available at the offices of the trustee.

We will issue the notes in minimum denominations of $200,000 and integral multiples of $1,000 in excess thereof. The notes of each series will be represented by one or more registered notes in global form without coupons deposited with a custodian and registered in the name of DTC or its nominee, in each case for credit to the accounts of direct and indirect participants, including Euroclear and Clearstream. In certain circumstances, the notes may be represented by definitive notes in certificated form. See “Description of the Debt Securities—Form, Book-entry and Transfer” in the accompanying prospectus.

The notes will not be redeemable prior to maturity, except as set forth below under “—Redemption for Taxation Reasons,” and will not be subject to any sinking fund.

Each series of notes will constitute our direct, unconditional, unsecured and unsubordinated general obligations and will at all times rank pari passu without any preference among themselves and with all our other unsecured obligations, other than our subordinated obligations and except for statutorily preferred obligations.

We are a holding company and conduct substantially all of our operations through our subsidiaries. As a result, claims of holders of the notes will be structurally subordinated to claims of creditors of our subsidiaries. In addition, our right to participate in any distribution of assets of any subsidiary (and thus the ability of holders of the notes to benefit as our creditors from such distribution) in bankruptcy, corporate reorganization, civil rehabilitation, liquidation or similar proceedings will be junior to creditors of that subsidiary, except to the extent that we may be recognized as a creditor of those subsidiaries. In addition, various statutes and regulations may restrict our subsidiaries from paying dividends or making loans or advances to us, including the Banking Act, the Companies Act and the Deposit Insurance Act. The restrictions could prevent our subsidiaries from paying the cash to us that we need in order to make payments under the notes. See “Risk Factors—Risks Related to the Notes—The notes will be structurally subordinated to indebtedness and other liabilities of our subsidiaries, including Sumitomo Mitsui Banking Corporation.”

Principal, Maturity and Interest for the Fixed Rate Notes

We expect to issue one or more series of fixed rate notes with the initial aggregate principal amount(s) and maturity date(s) set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering.” Principal in respect of the fixed rate notes will be repaid at maturity at a price of 100% of the principal amount.

S-26

Interest on the fixed rate notes of each series will accrue at the rate per annum, and from the date, set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering.” We will pay interest on the fixed rate notes of each series semiannually in arrears on the dates set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering,” to the persons in whose names the fixed rate notes are registered as of the close of business on the fifteenth day before the due date for payment (whether or not a Business Day). Interest on the fixed rate notes will be paid to but excluding the relevant interest payment date. We will compute interest on the fixed rate notes on the basis of a 360-day year consisting of twelve 30-day months. We will pay the principal of and interest on the fixed rate notes in U.S. dollars or in such other coin or currency of the United States as at the time of payment is legal tender for the payment of public and private debts.

If any payment is due on the fixed rate notes on a day that is not a Business Day, we will make payment on the date that is the next succeeding Business Day. Payments postponed to the next succeeding Business Day in this situation will be treated as if they were made on the original due date. Postponement of this kind will not result in a default under the fixed rate notes, and no interest will accrue on the postponed amount from the original due date to the next succeeding Business Day.

All payments in respect of the fixed rate notes will be subject in all cases to any applicable fiscal laws or other laws and regulations, and, except as described in “Description of the Debt Securities—Taxation and Additional Amounts” in the accompanying prospectus, no additional amounts will be payable as a result of the withholding or deduction of any taxes or duties of whatever nature imposed or levied as a result of such laws or regulations.

The term “Business Day” as used under “—Principal, Maturity and Interest for the Fixed Rate Notes” means any day which is not a day on which banking institutions in The City of New York, London or Tokyo are authorized or required by law, regulation or executive order to close.

Principal, Maturity and Interest for the Floating Rate Notes

We expect to issue one or more series of floating rate notes with the initial aggregate principal amount(s) and maturity date(s) (each, a “Floating Rate Notes Maturity Date”) set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering.” Principal in respect of the floating rate notes will be repaid at maturity at a price of 100% of the principal amount.

The floating rate notes of each series will bear interest at a rate per annum equal to Compounded Daily SOFR (as defined below) plus a margin (the “Margin”) set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering,” payable on each interest payment date set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering,” subject to adjustment as explained below (each, an “Interest Payment Date”), beginning on the first interest payment date as set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering,” and ending on the Floating Rate Notes Maturity Date or, if redeemed early, the date of such redemption. In no event shall the rate of interest for the floating rate notes be less than 0% for any Interest Period (as defined below).

Interest on the floating rate notes of each series will accrue from (and including) the issue date, set forth in the applicable pricing term sheet and described on the cover page of this prospectus supplement and under “Prospectus Supplement Summary—The Offering,” to (but excluding) the Floating Rate Notes Maturity Date or, if redeemed early, the date of such redemption. If any Interest Payment Date (other than the Floating Rate Notes Maturity Date or any redemption date under “—Redemption for Taxation Reasons”) falls on a day that is not a

S-27

Business Day, such Interest Payment Date will be adjusted in accordance with the Modified Following Business Day Convention. The term “Modified Following Business Day Convention” means that the relevant date shall be postponed to the first following day that is a Business Day (and interest will continue to accrue to, but excluding, such succeeding Business Day), unless that day falls in the next calendar month in which case that date will be the first preceding day that is a Business Day (and interest will accrue to, but excluding, such preceding Business Day). If the Floating Rate Notes Maturity Date or redemption date under “—Redemption for Taxation Reasons” would fall on a day that is not a Business Day, then any interest, principal or additional amounts, if any, as the case may be, will be paid on the next succeeding Business Day, and no interest shall accrue from and after the Floating Rate Notes Maturity Date or such redemption date.

The term “Business Day” as used under “—Principal, Maturity and Interest for the Floating Rate Notes” means a day that is a U.S. Government Securities Business Day (as defined below) and that in The City of New York, London and Tokyo, is not a day on which banking institutions are authorized or required by law, regulation or executive order to close.

We will pay interest on the floating rate notes of each series to the persons in whose names the floating rate notes are registered as of the close of business on the fifteenth day before the Interest Payment Date (whether or not a Business Day).

As further described herein, on each Interest Determination Date, the Calculation Agent (each as defined below) will calculate the amount of accrued interest payable on the floating rate notes of each series on the related Interest Payment Date by multiplying (i) the outstanding principal amount of the floating rate notes by (ii) the product of (a) the interest rate for the relevant Interest Period multiplied by (b) the number of days in the relevant Interest Period divided by 360. We will pay the principal of and interest on the floating rate notes in U.S. dollars or in such other coin or currency of the United States as at the time of payment is legal tender for the payment of public and private debts.

Secured Overnight Financing Rate

The Secured Overnight Financing Rate is published by the Federal Reserve Bank of New York and is intended to be a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities.

The Federal Reserve Bank of New York notes on its publication page for the Secured Overnight Financing Rate that use of the Secured Overnight Financing Rate is subject to important limitations, indemnification obligations and disclaimers, including that the Federal Reserve Bank of New York may alter the methods of calculation, publication schedule, rate revision practices or availability of the Secured Overnight Financing Rate at any time without notice.

Compounded Daily SOFR

The term “Compounded Daily SOFR” means, in respect of each Interest Period, the rate of return on a daily compounded interest investment during the relevant SOFR Observation Period (with the daily SOFR reference rate as the reference rate for the calculation of interest) and will be determined by the Calculation Agent on the relevant Interest Determination Date in accordance with the following formula:

with the resulting percentage being rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005 per cent. being rounded upwards (e.g., 9.876541 per cent. (or 0.09876541) being rounded

S-28

down to 9.87654 per cent. (or 0.0987654) and 9.876545 per cent. (or 0.09876545) being rounded up to 9.87655 per cent. (or 0.0987655)) and where:

“SOFR_i” for any U.S. Government Securities Business Day “i” in the relevant SOFR Observation Period, is equal to the SOFR reference rate for that U.S. Government Securities Business Day “i”;

Notwithstanding anything to the contrary in the documentation relating to the floating rate notes, if we or our designee determines on or prior to the relevant Reference Time (as defined below) that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining Compounded Daily SOFR or the then-current Benchmark (as defined below), then the benchmark replacement provisions set forth below under “—Benchmark Transition” will thereafter apply to all determinations of the rate of interest payable on the floating rate notes.

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest payable for each Interest Period on the floating rate notes will be an annual rate equal to the sum of the Benchmark Replacement (as defined below) and the applicable Margin.

The Bank of New York Mellon will serve as the “Calculation Agent” for the floating rate notes.

In the absence of gross negligence or willful default, the Calculation Agent’s determination of Compounded Daily SOFR and its calculation of the applicable interest rate for each Interest Period will be conclusive and binding on us and the holders of the floating rate notes. The Calculation Agent will make available the interest rates for current and preceding Interest Periods by delivery of such notice through such medium as is available to participants in DTC, Euroclear and Clearstream, or any successor thereof, and in accordance with such applicable rules and procedures as long as the floating rate notes are held in global form. We have the right to remove the Calculation Agent at any time, which removal will take effect on the date of the appointment by us of a successor Calculation Agent.

Benchmark Transition

Notwithstanding anything to the contrary in the documentation relating to the floating rate notes, if we or our designee determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to the-then current Benchmark, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the floating rate notes in respect of all determinations on such date and for all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, we or our designee will have the right to make Benchmark Replacement Conforming Changes (as defined below) from time to time without the consent of the Holders.

Any determination, decision or election that may be made by us or our designee pursuant to these Benchmark Transition provisions, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection (i) will be conclusive and binding on us, the trustee, the paying agent, the Calculation Agent and any other agents and the holders of the floating rate notes absent manifest error, (ii) if made by us, will be made in our sole discretion, (iii) if made by our designee, will be made after consultation with us, and the designee will not make any such determination, decision or election to which we object and (iv) notwithstanding anything to the contrary in the documentation relating to the floating rate notes, shall become effective without consent from the holders of the floating rate notes or any other party.

S-30

Any determination, decision or election pursuant to these Benchmark Transition provisions not made by our designee will be made by us on the basis as described above. The designee shall have no liability for not making any such determination, decision or election. In addition, we may designate an entity (which may be our affiliate) to make any determination, decision or election that we have the right to make in connection with these Benchmark Transition provisions.

We will promptly give notice of the determination of the Benchmark Replacement, the Benchmark Replacement Adjustment and any Benchmark Replacement Conforming Changes to the trustee, the paying agent, the Calculation Agent and the holders of the floating rate notes; provided that failure to give such notice will have no impact on the effectiveness of, or otherwise invalidate, any such determination.

For purposes of these Benchmark Transition provisions:

“Benchmark” means, initially, Compounded Daily SOFR; provided that if we or our designee determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded Daily SOFR (including any daily published component used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement;

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by us or our designee as of the Benchmark Replacement Date:

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by us or our designee as of the Benchmark Replacement Date:

S-31

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of “Interest Period,” changes to the timing and frequency of determining rates and making payments of interest, rounding of amounts or tenors, and other administrative matters) we or our designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if we or our designee decides that adoption of any portion of such market practice is not administratively feasible or if we or our designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as we or our designee determines is reasonably practicable);

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

S-32

“Corresponding Tenor” with respect to a Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding Business Day adjustment) as the applicable tenor for the then-current Benchmark;

“designee” means a designee as selected and separately appointed by us in writing;

“ISDA Definitions” means the 2021 ISDA Interest Rate Derivatives Definitions published by the International Swaps and Derivatives Association, Inc. or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time;

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor;

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective upon the occurrence of an index cessation date with respect to the Benchmark (including any daily published component used in the calculation thereof) for the applicable tenor excluding the applicable ISDA Fallback Adjustment;

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is the Compounded Daily SOFR, the SOFR Determination Time, or (2) if the Benchmark is not the Compounded Daily SOFR, the time determined by us or our designee after giving effect to the Benchmark Replacement Conforming Changes;

“Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/ or the Federal Reserve Bank of New York or any successor thereto; and

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

Redemption for Taxation Reasons

The notes of each series may be redeemed at our option, in whole, but not in part, at any time, subject to prior confirmation of the FSA (if such confirmation is required under applicable Japanese laws or regulations then in effect), on giving not less than thirty (30) nor more than sixty (60) days’ notice of redemption to the holders (which notice shall be irrevocable and shall conform to all requirements with respect to such notice as set forth in the Indenture) at a redemption price equal to 100% of the principal amount of such notes together with accrued and unpaid interest to (but excluding) the date fixed for redemption and any additional amounts thereon, if we have been or will become obliged to pay additional amounts with respect to such series as described in “Description of the Debt Securities—Taxation and Additional Amounts” in the accompanying prospectus as a result of any change in, or amendment to, the laws or regulations of Japan or any political subdivision or any authority thereof or therein having power to tax, or any change in application or official interpretation of such laws or regulations, which change or amendment becomes effective on or after the original issuance date of the notes of such series and such obligation cannot be avoided by the taking of reasonable measures available to us; provided, that no such notice of redemption shall be given sooner than ninety (90) days prior to the earliest date on which we would be obliged to pay such additional amounts were a payment then due in respect of such notes. Prior to the publication of any notice of redemption pursuant to this paragraph, we shall deliver to the trustee a certificate signed by an authorized officer stating that the conditions precedent to our right to so redeem have been fulfilled and an opinion of independent legal or tax advisor of recognized standing to the effect that we have become or will be obliged to pay such additional amounts as a result of such change or amendment.

S-33

Events of Default and Remedies

Holders of the notes will have certain rights if an event of default occurs. You should read the information under the heading “Description of Debt Securities—Events of Default and Rights of Acceleration—Senior Debt Securities” in the accompanying prospectus.

The events of default applicable to senior debt securities issued by us prior to March 31, 2019 (the “Pre-2019 Senior Debt”) provide for a 15-day cure period with respect to any failure by us to pay the principal and premium, if any, of any series of such Pre-2019 Senior Debt. In response to the Japanese TLAC Standards, which came into effect on March 31, 2019, we have modified the events of default applicable to the notes to provide for a 30-day cure period in the event of a principal or premium default. Accordingly, holders of the notes would not be entitled to accelerate their notes until after the expiration of a 30-day cure period, as compared to a 15-day cure period for holders of Pre-2019 Senior Debt, in the event that we fail to pay the principal and premium, if any, on the relevant series of notes when due.

The Trustee

The Bank of New York Mellon, a banking corporation organized and existing under the laws of the State of New York with limited liability, will be the trustee for the notes. The trustee may, subject to certain conditions, act as trustee for other securities issued by us or by our affiliates.

Paying Agent, Transfer Agent, Registrar and Calculation Agent

The Bank of New York Mellon, a banking corporation organized and existing under the laws of the State of New York with limited liability, will initially act as paying agent, transfer agent and registrar for each series of the notes and as calculation agent for the floating rate notes. We may change the paying agent, transfer agent, calculation agent or registrar without prior notice to holders of the notes, and we or any of our subsidiaries may act as paying agent, transfer agent, calculation agent or registrar.

Governing Law

The notes will be, and the Indenture is, governed by and construed in accordance with the laws of the State of New York.

TAXATION

Japanese Taxation

The following is a general description of certain aspects of Japanese taxation applicable to the notes. It does not purport to be a comprehensive description of the tax aspects of the notes. Prospective purchasers should note that, although the general tax information on Japanese taxation is described hereunder for convenience, the statements below are general in nature and not exhaustive.

Prospective purchasers are advised to consult their own legal, tax, accountancy or other professional advisers in order to ascertain their particular circumstances regarding taxation. The statements below are based on current tax laws and regulations in Japan and current income tax treaties executed by Japan all as in effect on the date of this prospectus supplement and all of which are subject to change or differing interpretations (possibly with retroactive effect). Neither such statements nor any other statements in this document are to be regarded as advice on the tax position of any beneficial owner of the notes or any person purchasing, selling or otherwise dealing in the notes or any tax implication arising from the purchase, sale or other dealings in respect of the notes.

The Notes

The notes do not fall under the concept of so-called “taxable linked bonds” as described in Article 6, Paragraph (4) of the Special Taxation Measures Act, i.e., bonds of which the amount of interest is to be calculated by reference to certain indexes (as prescribed by the Cabinet Order No. 43 of 1957, as amended, or the Cabinet Order, under the Special Taxation Measures Act) relating to the issuer of the notes or a specially-related person of the issuer.

Representation by Investor upon Distribution

By subscribing to the notes, an investor will be deemed to have represented that it is a beneficial owner that is, (i) for Japanese tax purposes, neither an individual resident of Japan or a Japanese corporation, nor an individual non-resident of Japan or a non-Japanese corporation that in either case is a specially-related person of the issuer or (ii) a Designated Financial Institution, as defined below. The notes are not as part of the distribution by the underwriters under the applicable underwriting agreement at any time to be directly or indirectly offered or sold to, or for the benefit of, any person other than a beneficial owner that is described in (i) or (ii) above, except as specifically permitted under the Special Taxation Measures Act.

Interest Payments on Notes and Redemption Gain

The following description of Japanese taxation (limited to national taxes) applies exclusively to interest on the notes and the redemption gain, meaning any positive difference between the acquisition price of the interest-bearing notes of the holder and the amount which the holder receives upon redemption of such interest-bearing notes, or the Redemption Gain, where such notes are issued outside Japan and payable outside Japan. In addition, the following description assumes that only global notes are issued for the notes, and no definitive notes and coupons that are independently traded are issued, in which case different tax consequences may apply. It is not intended to be exhaustive and prospective purchasers are recommended to consult their tax advisers as to their exact tax position.

1. Non-resident Investors

If the recipient of interest on the notes or of the Redemption Gain with respect to interest-bearing notes is an individual non-resident of Japan or a non-Japanese corporation for Japanese tax purposes, as described below, the Japanese tax consequences on such individual non-resident of Japan or non-Japanese corporation are

S-35

significantly different depending upon whether such individual non-resident of Japan or non-Japanese corporation is a specially-related person of the issuer. Most importantly, if such individual non-resident of Japan or non-Japanese corporation is a specially-related person of the issuer, income tax at the rate of 15.315% of the amount of such interest will be withheld by the issuer of the notes under Japanese tax law.

1.1. Interest

(1) If the recipient of interest on the notes is an individual non-resident of Japan or a non-Japanese corporation having no permanent establishment within Japan or having a permanent establishment within Japan but where the receipt of the interest on the notes is not attributable to the business of such individual non-resident of Japan or non-Japanese corporation carried on within Japan through such permanent establishment, no Japanese income tax or corporate tax is payable with respect to such interest whether by way of withholding or otherwise, if certain requirements are complied with, inter alia:

(i) if the relevant notes are held through certain participants in an international clearing organization such as DTC or certain financial intermediaries prescribed by the Special Taxation Measures Act and the Cabinet Order (each such participant or financial intermediary, a Participant), the requirement that such recipient provide, at the time of entrusting a Participant with the custody of the relevant notes, certain information prescribed by the Cabinet Order together with the Special Taxation Measures Act and the ministerial ordinance and other regulations thereunder, or the Act, to enable the Participant to establish that the recipient is exempt from the requirement for Japanese tax to be withheld or deducted, or the Interest Recipient Information, and advise the Participant if such individual non-resident of Japan or non-Japanese corporation ceases to be so exempted (including the case where it became a specially-related person of the issuer), and that the issuer of the notes prepare and file a certain confirmation prescribed by the Act, or the Interest Recipient Confirmation, in a timely manner based upon the Interest Recipient Information communicated through the Participant and the relevant international clearing organization; and

(ii) if the relevant notes are not held by a Participant, the requirement that such recipient submit to the relevant paying agent a written application for tax exemption (hikazei tekiyo shinkokusho), or the Written Application for Tax Exemption, together with certain documentary evidence, and that the issuer of the notes file the Written Application for Tax Exemption so received with the competent local tax office in a timely manner.

Failure to comply with such requirements described above (including the case where the Interest Recipient Information is not duly communicated as required under the Act) will result in the withholding by the issuer of the notes of income tax at the rate of 15.315% of the amount of such interest.

(2) If the recipient of interest on the notes is an individual non-resident of Japan or a non-Japanese corporation having a permanent establishment within Japan and the receipt of interest is attributable to the business of such individual non-resident of Japan or non-Japanese corporation carried on within Japan through such permanent establishment, such interest will not be subject to a 15.315% withholding tax by the issuer of the notes, if the requirements concerning the Interest Recipient Information and the Interest Recipient Confirmation or the Written Application for Tax Exemption as set out in paragraph 1.1(1) above are complied with. Failure to do so will result in the withholding by the issuer of the notes of income tax at the rate of 15.315% of the amount of such interest. The amount of such interest will be subject to regular income tax or corporate tax, as appropriate.

(3) Notwithstanding paragraphs 1.1(1) and (2), if an individual non-resident of Japan or a non-Japanese corporation mentioned above is a person who has a special relationship with the issuer of the notes (that is, in general terms, a person who directly or indirectly controls, or is directly or indirectly controlled by, or is under direct or indirect common control with, the issuer of the notes) within the meaning prescribed by the Cabinet Order under Article 6, Paragraph (4) of the Special Taxation Measures Act (such person is referred to as a specially-related person of the issuer) as of the beginning of the fiscal year of the issuer of the notes in which the

S-36

relevant interest payment date falls, the exemption from Japanese withholding tax on interest mentioned above will not apply, and income tax at the rate of 15.315% of the amount of such interest will be withheld by the issuer of the notes. If such individual non-resident of Japan or non-Japanese corporation has a permanent establishment within Japan, regular income tax or corporate tax, as appropriate, collected otherwise than by way of withholding, could apply to such interest under Japanese tax law.

(4) If an individual non-resident of Japan or a non-Japanese corporation (regardless of whether it is a specially-related person of the issuer) is subject to Japanese withholding tax with respect to interest on the notes under Japanese tax law, a reduced rate of withholding tax or exemption from such withholding tax may be available under the relevant income tax treaty between Japan and the country of tax residence of such individual non-resident of Japan or non-Japanese corporation. As of the date of this prospectus supplement, Japan has income tax treaties, conventions or agreements whereby the above-mentioned withholding tax rate is reduced, generally to 10% with, inter alia, Australia, Canada, Finland, France, Hong Kong, Ireland, Italy, Luxembourg, the Netherlands, New Zealand, Norway, Portugal and Singapore. Under the tax treaties between Japan and the United States, the United Kingdom, Denmark, Germany, Austria, Belgium, Sweden, Spain or Switzerland, interest paid to qualified United States, United Kingdom, Danish, German, Austrian, Belgian, Swedish, Spanish or Swiss residents is generally exempt from Japanese withholding tax (for Belgium, only for a Belgian enterprise). Under the current income tax treaties between Japan and France, Australia, the Netherlands or New Zealand, certain limited categories of qualified French, Australian, Dutch or New Zealand residents receiving interest on the notes may, subject to compliance with certain procedural requirements under Japanese law, be fully exempt from Japanese withholding tax on payments of interest on the notes (provided that no exemption will apply to pension funds in the case of Australia and New Zealand). In order to avail themselves of such reduced rate of, or exemption from, Japanese withholding tax under any applicable income tax treaty, individual non-residents of Japan or non-Japanese corporations which are entitled, under any applicable income tax treaty, to a reduced rate of, or exemption from, Japanese withholding tax on payment of interest by the issuer of the relevant notes are required to submit an Application Form for Income Tax Convention regarding Relief from Japanese Income Tax and Special Income Tax for Reconstruction on Interest (as well as any other required forms and documents) in advance through the issuer of the relevant notes to the relevant tax authority before payment of interest.

(5) Under the Act, if an individual non-resident of Japan or a non-Japanese corporation that is a beneficial owner of the notes becomes a specially-related person of the issuer, or an individual non-resident of Japan or a non-Japanese corporation that is a specially-related person of the issuer becomes a beneficial owner of the notes, and, if such notes are held through a Participant, then such individual non-resident of Japan or non-Japanese corporation should notify the Participant of such change in status by the immediately following interest payment date of the notes. As described in paragraph 1.1(3) above, as the status of such individual non-resident of Japan or non-Japanese corporation as a specially-related person of the issuer for Japanese withholding tax purposes is determined based on the status as of the beginning of the fiscal year of the issuer in which the relevant interest payment date falls, such individual non-resident of Japan or non-Japanese corporation should, by such notification, identify and advise the Participant of the specific interest payment date on which Japanese withholding tax starts to apply with respect to such individual non-resident of Japan or non-Japanese corporation as being a specially-related person of the issuer.

1.2. Redemption Gain

(1) If the recipient of the Redemption Gain is an individual non-resident of Japan or a non-Japanese corporation having no permanent establishment within Japan or having a permanent establishment within Japan but where the receipt of such Redemption Gain is not attributable to the business of such individual non-resident of Japan or non-Japanese corporation carried on within Japan through such permanent establishment, no income tax or corporate tax is payable by way of withholding or otherwise with respect to such Redemption Gain.

(2) If the recipient of the Redemption Gain is an individual non-resident of Japan or a non-Japanese corporation having a permanent establishment within Japan and the receipt of such Redemption Gain is

S-37

attributable to the business of such individual non-resident of Japan or non-Japanese corporation carried on within Japan through such permanent establishment, such Redemption Gain will not be subject to any withholding tax but will be subject to regular income tax or corporate tax, as appropriate.

(3) Notwithstanding paragraphs 1.2(1) and (2), if an individual non-resident of Japan or a non-Japanese corporation mentioned above is a specially-related person of the issuer as of the beginning of the fiscal year of the issuer of the notes in which such individual non-resident of Japan or non-Japanese corporation acquired such notes, the Redemption Gain will not be subject to withholding tax but will be subject to regular income tax or corporate tax, as appropriate, under Japanese tax law, regardless of whether such individual non-resident of Japan or non-Japanese corporation has a permanent establishment within Japan; provided that an exemption may be available under the relevant income tax treaty.

2. Resident Investors

If the recipient of interest on the notes is an individual resident of Japan or a Japanese corporation for Japanese tax purposes, as described below, regardless of whether such recipient is a specially-related person of the issuer, in addition to any applicable local tax, income tax will be withheld at the rate of 15.315% of the amount of such interest, if such interest is paid to an individual resident of Japan or a Japanese corporation (except for (i) a Designated Financial Institution which complies with the requirement for tax exemption under Article 6, Paragraph (11) of the Special Taxation Measures Act, or (ii) a Public Corporation, etc., as defined below, or a Specified Financial Institution, as defined below, to which such interest is paid through the Japanese Custodian, as defined below, in compliance with the requirement for tax exemption under Article 3-3, Paragraph (6) of the Special Taxation Measures Act.) In addition to the withholding tax consequences upon resident investors as explained in this section 2, resident investors should consult their own tax advisors regarding income tax or corporate tax consequences otherwise than by way of withholding, bearing in mind, especially for individual residents of Japan, the change to the taxation regime of bonds which took effect on January 1, 2016.

2.1. Interest

(1) If an individual resident of Japan or a Japanese corporation (other than a Specified Financial Institution or a Public Corporation etc. who complies with the requirement as referred to in paragraph 2.1(2)) receives payments of interest on the notes through certain Japanese payment handling agents, each a Japanese Payment Handling Agent, income tax at the rate of 15.315% of the amount of such interest will be withheld by the Japanese Payment Handling Agent rather than by the issuer of the notes. As the issuer of the notes is not in a position to know in advance the recipient’s status, the recipient of interest falling within this category should inform the issuer of the notes through a paying agent of its status in a timely manner. Failure to so inform may result in double withholding.

(2) If the recipient of interest on the notes is a Japanese public corporation or a Japanese public-interest corporation designated by the relevant law, or a Public Corporation etc., or a Japanese bank, a Japanese insurance company, a Japanese financial instruments business operator or other Japanese financial institution falling under certain categories prescribed by the relevant Cabinet Order under Article 3-3, Paragraph (6) of the Special Taxation Measures Act, each, a Specified Financial Institution, that keeps its notes deposited with, and receives the interest through, a Japanese Payment Handling Agent with custody of the notes, or the Japanese Custodian, and such recipient submits through such Japanese Custodian to the competent tax authority the report prescribed by the Act, no withholding tax is levied on such interest. However, since the issuer of the notes is not in a position to know in advance the recipient’s such tax exemption status, the recipient of interest falling within this category should inform the issuer of the notes through a paying agent of its status in a timely manner. Failure to so notify the issuer of the notes may result in the withholding by the issuer of the notes of a 15.315% income tax.

(3) If an individual resident of Japan or a Japanese corporation (except for a Designated Financial Institution which complies with the requirements described in paragraph 2.1(4)) receives interest on the notes not through a

S-38

Japanese Payment Handling Agent, income tax at the rate of 15.315% of the amount of such interest will be withheld by the issuer of the notes.

(4) If a Japanese bank, a Japanese insurance company, a Japanese financial instruments business operator or other Japanese financial institution falling under certain categories prescribed by the Cabinet Order under Article 6, Paragraph (11) of the Special Taxation Measures Act, each, a Designated Financial Institution, receives interest on the notes not through a Japanese Payment Handling Agent and the requirements concerning the Interest Recipient Information and the Interest Recipient Confirmation or the Written Application for Tax Exemption as referred to in paragraph 1.1(1) above are complied with, no withholding tax will be imposed.

2.2. Redemption Gain

If the recipient of the Redemption Gain is an individual resident of Japan or a Japanese corporation, such Redemption Gain will not be subject to any withholding tax.

3. Special Additional Tax for Reconstruction from the Earthquake

Due to the imposition of a special additional withholding tax of 0.315% (or 2.1% of 15%) to secure funds for reconstruction from the earthquake of March 11, 2011, the withholding tax rate has been effectively increased to 15.315% during the period beginning on January 1, 2013 and ending on December 31, 2037. On or after January 1, 2038, all references to the tax rate of 15.315% in the foregoing descriptions will read 15%. There is also certain special additional tax imposed upon regular income tax due otherwise than by way of withholding for individual non-residents of Japan, as referred to in the foregoing descriptions, for the period mentioned above.

Capital Gains, Stamp Tax and Other Similar Taxes, Inheritance and Gift Taxes

Gains derived from the sale of notes outside Japan by an individual non-resident of Japan or a non-Japanese corporation having no permanent establishment within Japan are, in general, not subject to Japanese income tax or corporate tax.

No stamp, issue, registration or similar taxes or duties will, under current Japanese law, be payable in Japan by noteholders in connection with the issue of the notes, nor will such taxes be payable by noteholders in connection with their transfer if such transfer takes place outside Japan.

Japanese inheritance tax or gift tax at progressive rates may be payable by an individual, wherever resident, who has acquired notes from another individual as legatee, heir or donee.

U.S. Federal Income Tax Considerations

The following is a description of material U.S. federal income tax consequences of the ownership and disposition of the notes by the U.S. Holders described below, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person’s decision to acquire notes. This discussion applies to you only if you are a U.S. Holder who purchases notes of any series pursuant to this offering at the “issue price,” which is the first price at which a substantial amount of the notes of that series is sold to the public (not including bond houses, brokers or similar persons acting in the capacity of underwriters, placement agents or wholesalers), and who holds the notes as capital assets for U.S. federal income tax purposes. This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to you in light of your particular circumstances, including the possible effect of the special tax accounting rules under Section 451 of the U.S. Internal Revenue Code of 1986, as amended, or the Code, alternative minimum tax and Medicare contribution tax consequences and differing tax consequences that may be applicable to you if you are, for instance:

S-39

If you are a partnership (or any other entity treated as a partnership) for U.S. federal income tax purposes, the U.S. federal income tax treatment of your partners will generally depend on the status of the partners and your activities. If you are a partnership or a partner in such partnership, you should consult your tax adviser as to your particular U.S. federal income tax consequences of owning and disposing of the notes.

This summary is based on the Code, administrative pronouncements, judicial decisions and Treasury regulations, and the income tax treaty between the United States and Japan, or the Treaty, changes to any of which subsequent to the date of this prospectus supplement may affect the tax consequences described herein, potentially with retroactive effect. This summary does not address any state, local or non-U.S. tax considerations, or any U.S. federal tax consequences (including estate or gift taxes) other than U.S. federal income tax consequences.

If you are considering the purchase of notes, you should consult your tax adviser with regard to the application of the U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

You are a U.S. Holder if, for U.S. federal income tax purposes, you are a beneficial owner of a note and:

Interest

The floating rate notes should be treated as “variable rate debt instruments” for U.S. federal income tax purposes and the remainder of this discussion so assumes. It is expected, and therefore this discussion assumes, that the notes of each series will be issued without original issue discount for U.S. federal income tax purposes. Interest paid on a note will be taxable to you as ordinary income at the time it accrues or is received, in accordance with your method of accounting for U.S. federal income tax purposes. The amount of interest taxable as ordinary income will include amounts, if any, withheld in respect of Japanese taxes and any additional amounts paid with respect thereto as described under “Description of the Debt Securities—Taxation and Additional Amounts” in the accompanying prospectus. See “—Japanese Taxation—The Notes—Interest Payments on Notes and Redemption Gain—1. Non-resident Investors” for a discussion of the requirements for obtaining an exemption from Japanese withholding tax.

Interest will constitute foreign-source income for U.S. federal income tax purposes, which may be relevant in calculating your foreign tax credit limitation. Any Japanese withholding tax on interest payments will not be

creditable against your U.S. federal income tax liability if the withholding tax results from your failure to provide the Interest Recipient Information or the Written Application for Tax Exemption described in “—Japanese Taxation” above, or to the extent the tax can be reduced or eliminated under the Treaty (which generally provides for an exemption from Japanese income tax on interest income). In addition, U.S. Treasury regulations impose additional requirements for non-U.S. taxes to be eligible for credit in the absence of an election to apply the benefits of an applicable income tax treaty, and we have not determined whether these requirements have been met with respect to Japanese withholding taxes, if any. The rules governing foreign tax credits are complex, and you should consult your tax adviser regarding the availability of foreign tax credits in your particular circumstances. Instead of claiming a credit, subject to applicable limitations, you may be able to elect to deduct any Japanese withholding taxes in computing your taxable income. An election to deduct non-U.S. taxes instead of claiming foreign tax credits applies to all creditable non-U.S. taxes paid or accrued in the taxable year.

Sale or Other Taxable Disposition of the Notes

Upon the sale or other taxable disposition of a note, you will recognize taxable gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and your tax basis in the note. For these purposes, the amount realized does not include any amount attributable to accrued interest, which is treated as described under “—Interest” above. Your tax basis in a note will generally equal the amount you paid for such note.

Gain or loss realized on the sale or other taxable disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other taxable disposition the note has been held for more than one year. Long-term capital gains recognized by non-corporate taxpayers are eligible to be taxed at rates lower than those applicable to ordinary income. The deductibility of capital losses is subject to limitations. Gain or loss generally will be U.S. source for purposes of computing your foreign tax credit limitation.

Backup Withholding and Information Reporting

Information returns may be required to be filed with the Internal Revenue Service in connection with payments on the notes and proceeds received from a sale or other disposition of the notes unless you are an exempt recipient. You may also be subject to backup withholding on these payments in respect of your notes unless you provide your taxpayer identification number and otherwise comply with applicable requirements of the backup withholding rules or, if required, you provide proof of an applicable exemption. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against your U.S. federal income tax liability, provided the required information is timely furnished to the Internal Revenue Service.

Certain U.S. Holders who are individuals (or certain specified entities) may be required to report information relating to the notes or non-U.S. accounts through which they may be held. You should consult your tax adviser regarding your reporting obligations with respect to the notes.

BENEFIT PLAN INVESTOR CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase of the notes by (i) employee benefit plans that are subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended, or ERISA, (ii) plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code or provisions under any other U.S. or non-U.S. federal, state, local or other laws or regulations that are similar to such provisions of the ERISA or the Code (collectively, Similar Laws), and (iii) entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each as described in the foregoing clauses (i), (ii) or (iii) referred to herein as a Plan).

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code, or a Covered Plan, and prohibit certain transactions involving the assets of a Covered Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of Covered Plan or the management or disposition of the assets of such Covered Plan, or who renders investment advice for a fee or other compensation to such a Covered Plan, is generally considered to be a fiduciary of the Covered Plan.

Before authorizing an investment in the notes of a portion of the assets of any Plan, a fiduciary should consider the fiduciary standards of ERISA, the Code or any Similar Law in the context of the Plan’s particular circumstances. Among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA, the Code or any Similar Law and would be consistent with the documents and instruments governing the Plan.

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit Covered Plans from engaging in certain transactions involving the “plan assets” with persons or entities who are “parties in interest” under ERISA, or “disqualified persons” under Section 4975 of the Code (in either case, Parties in Interest) with respect to such Covered Plans, unless an exemption is available. A Party in Interest that engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the Covered Plan that engaged in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code.

As a result of our business, we, the underwriters, the trustee or our or their respective affiliates (collectively, the Sellers) may be Parties in Interest with respect to many Covered Plans. Where any of the Sellers is a Party in Interest with respect to a Covered Plan (either directly or by reason of such Seller’s ownership interests in its directly or indirectly owned subsidiaries), the purchase and holding of the notes (including any interest in a note) by or on behalf of the Covered Plan could be a prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless exemptive relief were available under an applicable exemption (as described below).

Certain prohibited transaction class exemptions, or PTCEs, issued by the U.S. Department of Labor may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase or holding of the notes. Those class exemptions include PTCE 96-23 (for certain transactions determined by in-house asset managers), PTCE 95-60 (for certain transactions involving life insurance company general accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 90-1 (for certain transactions involving insurance company pooled separate accounts) and PTCE 84-14 (for certain transactions determined by independent qualified asset managers). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code may provide a limited exemption for the purchase and sale of the notes and related lending transactions, provided that neither we, the underwriters nor any of our or their affiliates have or exercise any discretionary

S-42

authority or control or render any investment advice with respect to the assets of the Covered Plan involved in the transaction and provided further that the Covered Plan pays no more, and receives no less, than adequate consideration in connection with the transaction (the so-called “service provider exemption”). Each of the above noted exemptions contains conditions and limitations on its application. These exemptions do not, for example, provide relief from the self-dealing prohibitions under ERISA and the Code. It should also be noted that even if the conditions specified in one or more of these exemptions are met, the scope of relief provided by these exemptions may not necessarily cover all acts that might constitute prohibited transactions. Therefore, fiduciaries of Covered Plans considering acquiring and/or holding the notes in reliance on these or any other exemption should carefully review the exemption and consult with their counsel to confirm that it is applicable. There can be no assurance that any of these or any other statutory or class exemptions will be available with respect to any particular transaction involving the notes.

Certain governmental plans (as defined in Section 3(32) of ERISA), church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as described in Section 4(b)(4) of ERISA), or Non-ERISA Arrangements, are not subject to the fiduciary responsibility or prohibited transaction rules of ERISA or Section 4975 of the Code, but may be subject to Similar Laws. Therefore, fiduciaries of Non-ERISA Arrangements should consult with their counsel regarding the potential consequences of an investment in the notes under any applicable Similar Laws before acquiring the notes.

Representation

Each purchaser and subsequent transferee of a note (including any interest in a note) pursuant to this prospectus supplement, including any fiduciary purchasing a note (or interest therein) on behalf of a Plan or a Non-ERISA Arrangement, will be deemed to have represented, in its corporate and its fiduciary capacity, that either (i) it is not acquiring or holding the notes with the assets of a Plan or Non-ERISA Arrangement or (ii) its acquisition, holding and subsequent disposition of the notes will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation under any applicable Similar Law.

Each purchaser and holder of the notes has exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the notes does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any applicable Similar Laws. The sale of any notes to any Plan or Non-ERISA Arrangement is in no respect a representation by us, the underwriters or any of our or their affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement, or that such an investment is appropriate for Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.

Neither this discussion nor anything in this prospectus supplement is or is intended to be investment advice directed at any potential purchaser that is a Plan or Non-ERISA Arrangement, or at such purchasers and holders generally, and such purchasers and holders should consult and rely on their own counsel and advisors as to whether an investment in the notes is suitable and consistent with ERISA, the Code and any Similar Laws, as applicable.

UNDERWRITING (CONFLICTS OF INTEREST)

Under the terms and subject to the conditions set forth in an underwriting agreement dated                , 2023, between us and the underwriters named below, for whom SMBC Nikko Securities America, Inc., Goldman Sachs & Co. LLC, Jefferies LLC and Citigroup Global Markets Inc. are acting as the representatives, the underwriters have severally, and not jointly, agreed to purchase, and we have agreed to sell to the underwriters, the respective principal amount of the notes listed opposite their names below.

The underwriters are entitled to be released and discharged from their obligations under, and to terminate, the underwriting agreement in certain circumstances prior to paying us for the notes. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased. The underwriters are offering the notes subject to their acceptance of the notes from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the notes are subject to approval of certain legal matters by their counsel and to certain other conditions.

The underwriting agreement provides that we will indemnify the underwriters and their affiliates against specified liabilities, including liabilities under the Securities Act, in connection with the offer and sale of the notes, and will contribute to payments the underwriters and their affiliates may be required to make in respect of those liabilities.

Commissions

The underwriters have advised us that they propose initially to offer each series of the notes at the public offering prices listed on the cover page of this prospectus supplement. After the initial offering, the public offering prices, concessions or any other term of the offering may be changed. The underwriters have agreed to purchase each series of the notes from us at the public offering price, and we have agreed to pay the underwriters a fee of                 % of the principal amount of the fixed rate notes and a fee of            % of the principal amount of the floating rate notes.

The estimated expenses of the offering, not including the underwriting commissions, to be incurred in connection with the offer and sale of the notes, are payable by us and include the following:

We have agreed to reimburse the underwriters for certain expenses in connection with this offering.

S-44

Price Stabilization and Short Positions

In connection with the offering, SMBC Nikko Securities America, Inc., or the Stabilization Manager, and/or any person acting on behalf thereof, may purchase and sell the notes in the open market and engage in other transactions, subject to applicable laws and regulations. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the Stabilization Manager and/or any person acting on behalf thereof of a greater principal amount of the notes than they are required to purchase from us in the offering. Stabilizing transactions consist of bids or purchases by the Stabilization Manager and/or any person acting on behalf thereof for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress. These transactions may also include stabilizing transactions by the Stabilization Manager and/or any person acting on behalf thereof for the accounts of the underwriters.

In addition, the Stabilization Manager and/or any person acting on behalf thereof may impose a penalty bid. A penalty bid is an arrangement that permits the Stabilization Manager and/or any person acting on behalf thereof to reclaim a selling concession from a syndicate member in connection with the offering when the notes originally sold by the syndicate member are purchased in syndicate covering transactions.

These activities may stabilize, maintain or otherwise affect the market prices of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time.

No Sale of Similar Securities

We have agreed, during the period from the date of this document through and continuing until the closing of the offering, without the prior written consent of the underwriters, not to, directly or indirectly, issue, sell, offer or contract to sell, grant any option for the sale of, or otherwise transfer or dispose of, in any market outside Japan, any U.S. dollar-denominated senior debt securities of SMFG.

Market Making Activity

The notes are new issues of securities with no established trading market. We have made an application to the Luxembourg Stock Exchange to list the notes on the official list of the Luxembourg Stock Exchange and for such notes to be admitted to trading on the Luxembourg Stock Exchange’s Euro MTF Market. The underwriters have advised us that they presently intend to make a market in the notes after completion of this offering. SMBC Nikko Securities America, Inc. and our other broker-dealer affiliates may use this prospectus supplement and the accompanying prospectus in connection with these activities. Such market making activity will be subject to the limits imposed by applicable laws. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. Broker-dealers subject to prospectus delivery requirements may be unable to engage in market-making transactions during certain periods of the year. A liquid or active public trading market for the notes may not develop. If an active trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial public offering price, depending on the market for similar securities, our performance and other factors. See “Risk Factors—Risks Related to the Notes—There is no prior market for the notes and, if a market develops, it may not be liquid.”

Selling Restrictions

General

No action has been or will be taken by us that would permit a public offering of the notes, or possession or distribution of this prospectus supplement, the accompanying prospectus, any amendment or supplement hereto or thereto, or any other offering or publicity material relating to the notes in any country or jurisdiction outside

S-45

the United States where, or in any circumstances in which, action for that purpose is required. Accordingly, the notes may not be offered or sold, directly or indirectly, and this prospectus supplement, the accompanying prospectus, any amendment or supplement hereto or thereto, and any other offering or publicity material relating to the notes may not be distributed or published, in or from any country or jurisdiction outside the United States except under circumstances that will result in compliance with applicable laws and regulations.

Japan

The notes have not been and will not be registered under the FIEA, and are subject to the Special Taxation Measures Act. Each underwriter has represented, warranted, and agreed that (i) it has not, directly or indirectly, offered or sold and will not, directly or indirectly, offer or sell any of the notes in Japan or to any person resident in Japan for Japanese securities law purposes (including any corporation or other entity organized under the laws of Japan) or to others for reoffering or resale, directly or indirectly, in Japan or to, or for the benefit of, any person resident in Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the FIEA and any other applicable laws, regulations and governmental guidelines of Japan; and (ii) it has not, directly or indirectly, offered or sold and will not, as part of its distribution under the underwriting agreement at any time, directly or indirectly, offer or sell any of the notes to, or for the benefit of, any person other than a beneficial owner that is, (a) for Japanese tax purposes, neither (x) an individual resident of Japan or a Japanese corporation, nor (y) an individual non-resident of Japan or a non-Japanese corporation that in either case is a person having a special relationship with the issuer of the notes as described in Article 6, Paragraph (4) of the Special Taxation Measures Act or (b) a Japanese financial institution, designated in Article 6, Paragraph (11) of the Special Taxation Measures Act. Notwithstanding the aforementioned restriction, pursuant to the Special Taxation Measures Act, SMBC Nikko Securities America, Inc., acting in its capacity as an underwriter, will be permitted to acquire or purchase, as part of the distribution under the underwriting agreement of the notes, the remainder of the notes from any of the other underwriters, where such other underwriter has failed to sell to subsequent purchasers all of the notes that it acquired or purchased from us in its capacity as an underwriter.

Canada

The notes may be sold only in any province of Canada to purchasers purchasing, or deemed to be purchasing, as principal that are both accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement (including any amendment hereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Under Canadian securities law, National Instrument 33-105 Underwriting Conflicts (NI 33-105) provides disclosure requirements with respect to potential conflicts of interest between an issuer and underwriters, dealers or placement agents, as the case may be. To the extent any conflict of interest between us and any of the underwriters (or any other placement agent acting in connection with this offering) may exist in respect of this offering, the applicable parties to this offering are relying on the exemption from these disclosure requirements provided to them by section 3A.3 of NI 33-105 (Exemption based on U.S. disclosure).

Upon receipt of this document, each Canadian purchaser hereby confirms that it has expressly requested that all documents evidencing or relating in any way to the sale of the securities described herein (including for

S-46

greater certainty any purchase confirmation or any notice) be drawn up in the English language only. Par la réception de ce document, chaque acheteur canadien confirme par les présentes qu’il a expressément exigé que tous les documents faisant foi ou se rapportant de quelque manière que ce soit à la vente des valeurs mobilières décrites aux présentes (incluant, pour plus de certitude, toute confirmation d’achat ou tout avis) soient rédigés en anglais seulement.

The notes may not be publicly offered, directly or indirectly, in Switzerland within the meaning of the Swiss Financial Services Act (the “FinSA”) and no application has or will be made to admit the notes to trading on any trading venue (exchange or multilateral trading facility) in Switzerland. Neither this document nor any other offering or marketing material relating to the notes constitutes a prospectus pursuant to the FinSA, and neither this document nor any other offering or marketing material relating to the notes may be publicly distributed or otherwise made publicly available in Switzerland.

Hong Kong

The notes may not be offered or sold by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies (Winding up and Miscellaneous

S-47

Provisions) Ordinance (Cap. 32, Laws of Hong Kong) or (ii) to “professional investors” as defined in the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder or (iii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies (Winding up and Miscellaneous Provisions) Ordinance (Cap. 32, Laws of Hong Kong), and no advertisement, invitation or document relating to the notes may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the laws of Hong Kong) other than with respect to notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.

Singapore

This document has not been and will not be registered as a prospectus with the Monetary Authority of Singapore. Accordingly, this document and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the notes may not be circulated or distributed, nor may any notes be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to any person in Singapore other than:

Where notes are subscribed or purchased under Section 275 of the SFA by a relevant person which is:

securities or securities-based derivatives contracts (each term as defined in Section 2(1) of the SFA) of that corporation or the beneficiaries’ rights and interest (howsoever described) in that trust shall not be transferred within six months after that corporation or that trust has acquired the notes pursuant to an offer made under Section 275 of the SFA except:

S-48

Any reference to the SFA is a reference to the Securities and Futures Act 2001 of Singapore and a reference to any term as defined in the SFA or any provision in the SFA is a reference to that term or provision as modified or amended from time to time including by such of its subsidiary legislation as may be applicable at the relevant time.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking and commercial banking services for us or our subsidiaries and affiliates, for which they received or will receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities), financial instruments (including bank loans), currencies and commodities for their own account and for the accounts of their customers, and such investment and securities activities may involve securities, instruments or assets of ours or related to our business. If any of the underwriters and their respective affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their respective affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their respective affiliates may also make investment recommendations and may publish or express independent research views in respect of such securities or instruments or in respect of assets, currencies or commodities that may be related to our business, and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities, instruments, currencies or commodities.

We have certain longstanding business arrangements with Goldman Sachs, including an arrangement for us to provide credit loss protection.

We have a strategic business alliance with Citigroup Inc., including an arrangement for Citigroup Inc. to provide us with global corporate and investment banking network access.

We have a strategic business alliance with Jefferies Financial Group, Inc. to collaborate on corporate and investment banking business opportunities, as well as in equity sales, trading, and research.

Conflicts of Interest

SMBC Nikko Securities America, Inc. is an affiliate of ours and, as a result, has a “conflict of interest” under Rule 5121. Consequently, this offering is being conducted in compliance with the provisions of Rule 5121. Because this offering is of notes that are rated investment grade, pursuant to Rule 5121, the appointment of a “qualified independent underwriter” is not necessary. SMBC Nikko Securities America, Inc. will not confirm sales to accounts over which it exercises discretionary authority without the prior specific written approval of its customer.

Settlement

We expect delivery of the notes will be made against payment therefor on or about                 , 2023, which is the                  New York business day following the date of pricing of the notes. Under Rule 15c6-1 of the U.S. Securities Exchange Act of 1934, as amended, or the Exchange Act, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing of the notes will be required, by virtue of the fact that the notes initially will settle                  New York business days after pricing of the notes, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC utilizing a “shelf” registration process. Under this shelf registration process, we may, from time to time, sell the debt securities described in this prospectus in one or more offerings.

This prospectus provides you with a general description of the debt securities that we may offer. Each time we sell debt securities, we will provide a prospectus supplement that will contain specific information about the terms of the debt securities and the offering. The prospectus supplement may also add, update or change information contained in this prospectus. The prospectus supplement will supersede this prospectus to the extent it contains information that is different from, or conflicts with, the information contained in this prospectus. You should read this prospectus, any applicable prospectus supplement and any related free writing prospectus that we authorize to be delivered to you together with additional information described under the heading “Where You Can Find More Information” beginning on page 28 of this prospectus before purchasing any of our securities.

We have not authorized any other person to provide you with any information other than that contained or incorporated by reference in this prospectus or in any applicable prospectus supplement or free writing prospectus prepared by or on behalf of us or to which we have referred you. “Incorporated by reference” means that we can disclose important information to you by referring you to another document filed separately with the SEC. We are not responsible for, and can provide no assurance as to the accuracy of, any other information that any other person may give you. We are not making, nor will we make, an offer to sell securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information appearing in this prospectus or in any applicable prospectus supplement or free writing prospectus prepared by or on behalf of us or to which we have referred you, including any information incorporated by reference herein or therein, is accurate as of any date other than their respective dates. Our business, financial condition, results of operations and prospects may have changed since those respective dates.

In this prospectus and any prospectus supplement, where information is presented in millions of yen or thousands or millions of dollars, amounts of less than one thousand or one million, as the case may be, have been truncated. Where information is presented in billions or trillions of yen or billions of dollars, amounts of less than one billion or one trillion, as the case may be, have been rounded. Accordingly, the total of each column of figures may not be equal to the total of the individual items. All percentages have been rounded to the nearest percent, one-tenth of one percent or one-hundredth of one percent, as the case may be.

Unless otherwise specified or required by the context: references to “days” are to calendar days; references to “years” are to calendar years and to “fiscal years” are to our fiscal years ending on March 31; references to “$,” “dollars” and “U.S. dollars” are to United States dollars and references to “yen” and “¥” are to Japanese yen. Unless otherwise specified, when converting currencies into yen we use the Sumitomo Mitsui Banking Corporation’s median exchange rates for buying and selling spot dollars, or other currencies, by telegraphic transfer against yen as determined at the end of the relevant fiscal period. Unless the context otherwise requires, “SMFG,” the “issuer,” “we,” “us,” “our,” and similar terms refer to Sumitomo Mitsui Financial Group, Inc. as well as to its subsidiaries. “SMBC” refers to Sumitomo Mitsui Banking Corporation, which is one of our commercial banking subsidiaries, or to Sumitomo Mitsui Banking Corporation and its subsidiaries, taken as a whole, as the context requires. References to “non-consolidated” information are to the financial information solely of SMBC.

Our primary financial statements for SEC reporting purposes are prepared on an annual and semi-annual basis in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, or IFRS, while our financial statements for reporting in our jurisdiction of incorporation and Japanese bank regulatory purposes are prepared in accordance with accounting principles generally accepted in Japan, or Japanese GAAP.

For a description of certain differences between IFRS and Japanese GAAP, see “Item 5.A Operating Results—Reconciliation with Japanese GAAP” in our most recent annual report on Form 20-F filed with the SEC. You should consult your own professional advisers for a more complete understanding of the differences between IFRS, Japanese GAAP, U.S. GAAP and the generally accepted accounting principles of other countries and how those differences might affect the financial information contained or incorporated by reference in this prospectus or the accompanying prospectus.

Financial information for us contained or incorporated by reference herein is presented in accordance with IFRS or Japanese GAAP, as specified herein or in the relevant document being incorporated by reference. Financial information for SMBC contained or incorporated by reference herein is presented in accordance with Japanese GAAP.

DESCRIPTION OF THE DEBT SECURITIES

The following is a summary of certain general terms and provisions of the senior and subordinated debt securities, collectively the “debt securities,” that we may offer under this prospectus. The specific terms and provisions of a particular series of debt securities to be offered, and the extent, if any, to which the general terms and provisions summarized below apply to such securities, will be described in an applicable prospectus supplement or free writing prospectus that we authorize to be delivered in connection with such offering. If there is any inconsistency between the general terms and provisions presented here and those in the applicable prospectus supplement or free writing prospectus, those in the applicable prospectus supplement or free writing prospectus will apply.

Because this section is a summary, it does not describe every aspect of the debt securities. It is qualified in its entirety by the provisions of the senior and subordinated indentures (as described below) and the senior and subordinated debt securities, which have been filed as exhibits to the registration statement of which this prospectus is part. You should refer to those documents for additional information.

When we refer to “the Company,” “we,” “our,” and “us” in this section, we mean Sumitomo Mitsui Financial Group, Inc., excluding, unless the context otherwise requires or as otherwise expressly stated, any existing or future subsidiaries.

General

We may issue senior debt securities from time to time, in one or more series under a senior indenture between us and The Bank of New York Mellon, which we refer to as the senior trustee, dated as of March 9, 2016, as amended or supplemented from time to time. We may issue subordinated debt securities from time to time, in one or more series under a subordinated indenture between us and The Bank of New York Mellon, which we refer to as the subordinated trustee, dated as of September 17, 2019, as amended or supplemented from time to time. The senior indenture and the subordinated indenture are sometimes referred to in this prospectus collectively as the “indentures” and each, individually, as an “indenture,” and the senior trustee and the subordinated trustee are sometimes referred to in this prospectus as the “trustee.” The terms “senior indenture,” “subordinated indenture” and “indenture” as used herein may, depending on the context, refer to such indenture, as amended or supplemented.

The indentures provide that we may issue debt securities up to an aggregate principal amount as we may authorize from time to time. Neither of the indentures limits the amount of debt securities that we may issue thereunder, nor contains any limitations on the amount of other indebtedness or other liabilities that we or any of our subsidiaries may incur.

The senior debt securities of each series will constitute our direct, unconditional, unsecured and unsubordinated general obligations and will at all times rank pari passu without any preference among themselves and with all our other unsecured obligations, other than our subordinated obligations and except for statutorily preferred obligations.

The subordinated debt securities of each series will constitute our direct and unsecured obligations and will at all times rank pari passu and without any preference among themselves and at least equally and ratably with all of our indebtedness that is subordinated to “Senior Indebtedness” (as defined in the subordinated indenture) and is in priority to all of our perpetual subordinated indebtedness, including indebtedness in respect of preference or other shares or any other indebtedness which ranks, or is expressed to rank, pari passu with, or junior to, indebtedness in respect of perpetual subordinated indebtedness. The nature and extent of the subordinated ranking of, and the other subordination provisions applicable to, a series of subordinated debt securities will be further described in the applicable prospectus supplement relating to such series of subordinated debt securities.
