The dollar was largely unchanged against the yen and the euro in quiet trading in Asia on Friday, with the reduced number of market participants amid the holiday season avoiding any major moves.

As of 0515 GMT, the dollar was at Y120.20 from Y120.15 late Thursday in North America. The euro was at $1.2216 from $1.2222.

After flows related to commercial transaction settlements ran their course in the middle of the morning, the dollar became largely static, with its downside well supported above Y120, as fears about risk factors such as tumbling oil prices receded.

Investors played down a slew of Japanese economic indicators released earlier in the day such as inflation, industrial output and labor data. While the data showed inflation slowing in Japan, despite efforts to get it to increase, the market reaction to the November figures was largely muted.

"Although it may be premature to say Y120 is completely supported, I feel that Y115 and Y117 are a considerable distance from where we are now," said Marito Ueda, director of FX Prime byGMO.

After the return of participants in the U.S. and Europe from the Christmas vacation, Mr. Ueda said the focus will be on whether the dollar will test its upside beyond a recent high of Y121.86 set on Dec. 8 and approach the Y122 line during the coming week.

"It's the market of a stronger dollar rather than a weaker yen," and investors will likely shift their focus more to the growing gap in interest rates between U.S. and Japan, said Mr. Ueda.

With U.S.-Japan bond yield differentials widening rapidly since earlier this month, the dollar may "rise (against the yen) as it catches up with the gap after market liquidity normalizes," following the holiday season this week, said J.P. Morgan chief FX strategist Junya Tanase.

Noting that the yield gap between two-year Japanese government bonds and the corresponding U.S. Treasurys is now at the widest level since May 2010, Mr. Tanase estimates that a dollar-yen rate consistent with the gap should be in a range up to the lower half of the Y126-level from the lower half of the Y121-level.

Earlier Friday, government data showed the rate of increase in Japan's core consumer price index--adjusted for volatile fresh-food prices and the impact of a national sales tax increase in April--fell to 0.7% in November from a 0.9% rise the previous month.

Industrial production fell 0.6% from the previous month, adjusted for seasonal variations, according to separate data, confounding economists' forecast for a 0.8% increase.

These figures indicate that the economy is still struggling to emerge from a recession. The yield on the benchmark 10-year Japanese government bonds fell to a record low of 0.300% following the release of the data. But stock investors largely shrugged off the figures. The Nikkei Stock Average was up a moderate 0.1% in afternoon trading.

In other currency trading, the euro was at Y146.82 from Y146.83.

The WSJ Dollar Index, a measure of the dollar against a basket of major currencies, was up 0.07% at 82.52.
