TOKYO (Reuters) -Japan's Nikkei share average climbed 6% on Tuesday, rebounding from a 1-1/2-year low hit in the previous session, as investors scooped up stocks, encouraged by signs of a recovery on Wall Street.

As of 0202 GMT, the Nikkei index was up 6.5% at 33,161.72, while the broader Topix traded 6.8% higher at 2,444.44.

"Investors bought back stocks as they thought the shares were oversold. They saw signs of a market recovery as U.S. stock futures rose in Japan trade," said Takamasa Ikeda, senior portfolio manager, GCI Asset Management.

The S&P 500 and the Dow closed lower, while the technology-heavy Nasdaq posted marginal gains on Monday following a roller coaster session.[.N]

U.S. semiconductor index climbed 2.7% overnight, while S&P and Nasdaq futures each rose more than 1% in Asia trade on Tuesday, signalling cues of a recovery.

Both the Nikkei and Topix are down roughly 13% from levels before U.S. President Donald Trump's Liberation Day tariff announcement, raising concerns about the impact on export-dependent Japan.

Japanese Prime Minister Shigeru Ishiba said on Monday that during a phone call with Trump, he expressed disappointment with the tariff policies and urged him to reconsider.

Gains on Tuesday were further supported by optimism that tariffs on Japan could be eased through negotiations between the two nation's leaders, Ikeda said.
