TOKYO (Kyodo) -- Tokyo stocks ended at new all-time highs for a fourth straight trading day on Tuesday, with the Nikkei index briefly rising above the 45,000 line for the first time, boosted by semiconductor-related shares amid hopes for robust demand.

The 225-issue Nikkei Stock Average advanced 134.15 points, or 0.30 percent, from Friday at 44,902.27. The broader Topix index finished 7.87 points, or 0.25 percent, higher at 3,168.36.

Japanese markets were closed Monday for a public holiday.

On the top-tier Prime Market, the main gainers were oil and coal product, transportation equipment and farm and fishery issues.

The U.S. dollar weakened to the upper 146 yen level in Tokyo as expectations for an interest rate cut by the Federal Reserve grew after the U.S. Senate confirmed Stephen Miran, one of President Donald Trump's close aides, to serve on the central bank board, dealers said.

At 5 p.m., the dollar fetched 146.88-90 yen compared with 147.37-47 yen in New York at 5 p.m. Monday.

The euro was quoted at $1.1794-1795 and 173.24-28 yen against $1.1755-1765 and 173.34-44 yen in New York late Monday afternoon.

The yield on the benchmark 10-year Japanese government bond ended at 1.605 percent, up 0.010 percentage point from Friday's close, as the debt was sold amid rises in Tokyo stocks.

Stocks climbed as some key U.S. stock indexes finished at all-time highs Monday on hopes that the Fed will ease monetary policy after data showed a slowing labor market, while chip shares were bought on prospects for solid demand for artificial intelligence.

The market was also lifted after the United States and China reached a deal to keep TikTok operational in the United States, helping to fuel expectations for progress in bilateral trade talks, brokers said.

"Chip shares were strong due to the effect of lower U.S. interest rates while market participants took the positive view that U.S.-China talks are heading in a friendly direction," said Masahiro Yamaguchi, head of investment research at SMBC Trust Bank.

Although the Nikkei benchmark exceeded the 45,000 mark for the first time, it failed to finish above the threshold as some investors locked in gains after recent steep rises.
