TOKYO (Kyodo) -- Tokyo stocks fell slightly Tuesday as investors locked in gains following the record closing highs of both the Nikkei and Topix indexes the previous day, although the market remained firm as investors scooped up issues seen as underperforming.

The 225-issue Nikkei Stock Average ended down 162.10 points, or 0.25 percent, from Monday at 64,996.09. The broader Topix index finished 4.11 points, or 0.10 percent, lower at 3,938.46.

On the top-tier Prime Market, the main decliners were pharmaceutical, nonferrous metal and wholesale trade issues.

The U.S. dollar moved slightly around the 159 yen line in Tokyo as a wait-and-see mood prevailed amid U.S.-Iran peace talks.

At 5 p.m., the dollar fetched 159.19-21 yen compared with 158.96-98 yen in Tokyo at 5 p.m. Monday.

The euro was quoted at $1.1637-1639 and 185.26-30 yen against $1.1637-1638 and 184.99-185.03 yen in Tokyo late Monday afternoon.

The yield on the benchmark 10-year Japanese government bond ended up 0.030 percentage point from Monday's close at 2.720 percent, rebounding from the previous day's buying.

U.S. markets were closed Monday for a public holiday.

Stocks were pressured after the Nikkei index surged more than 5,300 points over the past three trading days, with some technology shares, including Advantest and Tokyo Electron, leading declines following recent gains.

Meanwhile, companies whose shares have underperformed recently were actively bought, helping maintain market sentiment. Heavyweight SoftBank Group also extended gains after a report last week that OpenAI, in which the group invests, is preparing to file for an initial public offering.

"The market's firm tone has been sustained as investors are picking up underperformers, reaffirming expectations for higher prices of Japanese stocks," said Toshikazu Horiuchi, equity strategist at IwaiCosmo Securities Co.

Optimism over the Middle East situation continued to support sentiment, briefly lifting both indexes into positive territory after a report said a proposed peace deal includes the full reopening of the Strait of Hormuz about 30 days after an agreement is reached.
