The dollar was a tad higher against the yen but moderately fell against the euro in Asia trade Thursday, as investors largely kept a wait-and-see stance ahead of the release of U.S. jobs data later in the day.

Around 0450 GMT, the dollar was higher at Y123.35, compared with Y123.17 late Wednesday in New York. The U.S. currency, however, weakened against the euro on short covering, with the common currency changing hands at $1.1072, compared with $1.1053 overnight.

With no signs of progress in Greek bailout talks ahead of Sunday's referendum on eurozone bailout conditions, investors are now shifting their focus back to U.S. fundamentals to shape their views on the likely timing for the Federal Reserve to raise short-term rates.

On Wednesday, Greece's Prime Minister Alexis Tsipras said that Greeks backing bailout terms demanded by the country's international creditors at a coming referendum are "accomplices" to those looking to continue austerity in the crisis-hit nation. Mr. Tsipras also blamed international creditors for the country's decision to shut down banks earlier this week.

Eurogroup head Jeroen Dijsselbloem said Wednesday there are no grounds for further talks on Greece at this point.

"Market sentiment is slightly biased upward," on better-than-expected U.S. ADP jobs and ISM manufacturing numbers overnight, said Shinichiro Kadota, vice president of research at Barclays in Tokyo. In addition, there are deep-seated views among market players that Greeks will back the eurozone bailout conditions at Sunday's referendum.

But "investors found it difficult to make moves ahead of the jobs data," said Mr. Kadota. "If the pair stays around its current level, I guess I have to say there's a possibility" of the pair reaching Y124 after a strong jobs report. But he said he's not sure if the market will fully react to the data in the usual way due to the Greek issue.

Barclays expects nonfarm payrolls grew by 250,000 in June, better than a market consensus for 233,000.

Still, some participants warned about taking strong positions ahead of a three-day weekend in the U.S. and the Greek referendum on Sunday, with many investors poised to close out their positions beforehand.

"It's impossible to take lopsided positions," ahead of the weekend for fears about risk aversion and the resultant yen buying potentially kicking in on Monday depending on the results of the Greek referendum, said Yasuaki Amatatsu, senior analyst of global markets research at Bank of Tokyo-Mitsubishi UFJ.

In other currency pairs, the euro was at Y136.53 from Y136.14.

The WSJ Dollar Index, a measure of the dollar against a basket of major currencies, was down 0.04% at 87.15.
