TOKYO (Kyodo) -- Tokyo stocks ended mixed Thursday as investors locked in gains, sending the Nikkei index to a record intraday high for a third straight trading day on hopes for expansionary fiscal policies in Japan.

The 225-issue Nikkei Stock Average ended down 10.70 points, or 0.02 percent, from Tuesday at 57,639.84. The broader Topix index finished 26.88 points, or 0.70 percent, higher at 3,882.16, closing at a record high.

Japanese financial markets were closed on Wednesday for a national holiday.

On the top-tier Prime Market, main gainers were mining and nonferrous metal issues, while service and air transportation shares were notable decliners.

The U.S. dollar briefly weakened to the lower 152 yen level in Tokyo as the currency remained under pressure following a report earlier this week that Chinese regulators advised financial institutions to curb their holdings of U.S. Treasuries, dealers said.

The yen was also bought as concerns about Japan's fiscal health eased after Prime Minister Sanae Takaichi said Monday that the government will not issue deficit-covering bonds to fund the ruling party's pledged two-year suspension of the food tax, dealers said.

The Nikkei stock index briefly topped 58,000 for the first time on expectations for stimulus measures under the Takaichi government after Japan's ruling Liberal Democratic Party scored a landslide victory in the general election on Sunday.

Heavyweight technology shares advanced after a major U.S. semiconductor-manufacturing firm released an upbeat earnings report on Wednesday on the back of strong demand for artificial intelligence.

However, the market was pressured by declines in export-related issues amid a stronger yen and selling after surges, with the key Nikkei index adding more than 3,800 points over the past three trading days.

"There might have been a sense of accomplishment after the Nikkei surpassed the 58,000 line amid caution about overheating following the rapid rise," said Toshikazu Horiuchi, equity strategist at IwaiCosmo Securities Co.
