The U.S. dollar was firmer in the upper 156 yen range Tuesday morning in cautious Tokyo trading, a day after Japanese authorities were suspected to have stepped in to push the Japanese currency sharply higher after its drop to a new 34-year low.
At noon, the dollar fetched 156.72-73 yen compared with 156.30-40 yen in New York at 5 p.m. Monday.
The euro was quoted at $1.0706-0707 and 167.78-81 yen against $1.0716-0726 and 167.33-43 yen in New York late Monday afternoon.
Tokyo stocks were higher, led by exporters that were boosted by the yen's weaker tone against the dollar. Solid gains in the tech sector also helped lift the stock market.
The 225-issue Nikkei Stock Average rose 524.25 points, or 1.38 percent, from Friday to 38,459.01. The broader Topix index was up 54.06 points, or 2.01 percent, at 2,740.54.
Japanese financial markets were closed on Monday for a national holiday.
