(Corrects first paragraph to say Nikkei closed over 33,000, not 30,000)

TOKYO - Japan's benchmark Nikkei gauge surged on Tuesday, closing over 33,000 for the first time in 33 years, led by technology shares on expectations of a flood of investment in chip-related companies.

SoftBank Group Corp jumped 5.25% on reports it may team up on an AI venture with ChatGPT operator OpenAI and that its semiconductor unit Arm is in investment talks with Intel Corp. Chip-testing equipment maker Advantest Corp soared 4.79%.

Toyota Motor Corp shares leapt 4.99% after the automaker announced plans to market next-generation battery electronic vehicles (EVs) from 2026.

The Nikkei climbed for a third-straight session, adding 1.8% to 33,018.65, closing above the key psychological level for the first time since July 1990. The broader Topix gained 1.16% to 2,264.79.

Global shares climbed on Monday ahead of closely watched U.S. inflation data on and policy decisions from the Federal Reserve, Bank of Japan, and other central banks.

Toyota's EV strategy "was well received by the market, and also last night the U.S. market was strong, so we have a strong market today," said Daiwa Securities strategist Kenji Abe.

With expectations of a soft landing in the U.S. and Fed easing later in the year, "this high valuation is likely to continue for the time being," he added.

Among Nikkei constituents, 170 companies advanced, while 54 declined. Drugmaker Eisai Co Ltd was an outlier, giving back 2.22% after a surge on Monday on positive news about its Alzheimer's treatment.

The auto sector rose 3.4% to become the best performer among the Tokyo Stock Exchange's 33 industry sub-indexes. A basket of paper producers was the biggest loser, falling 1.05%.
