Japan's Nikkei ends at near 3-week high on Wall Street gains, trading firms jump

TOKYO, March 18 (Reuters) - Japan's Nikkei share average ended at a nearly three-week high on Tuesday, tracking Wall Street's overnight gains, driven by trading firms.

The Nikkei index .N225 rose 1.2% to 37,845.42, its highest close since February 27, in a third straight session of gains.

The broader Topix .TOPX rose 1.29% to 2,783.56.

"Investors were relieved to see some positive cues, such as Wall Street's gains and a rally of domestic trading houses, but the overall situation has not changed," said Yusuke Sakai, a senior trader at T&D Asset Management.

"The possible impact of the (U.S. President Donald Trump's) tariff policy weighs on the sentiment," Sakai said.

U.S. stocks gained for a second straight session on Monday, as investors sought bargains after Nasdaq's and the S&P 500's four-week tumble and assessed the latest economic data to gauge the impact of the Trump administration's policies. .N

In Japan, trading firms jumped after Warren Buffett's Berkshire Hathaway BRKa.N raised its holdings in five Japanese trading houses.

Mitsui & Co 8031.T rose 3.08% and Mitsubishi Corp 8058.T climbed 3.61%.

Uniqlo-owner Fast Retailing 9983.T rose 1.1% and chip-testing equipment maker Advantest 6857.T jumped 2.76%.

Earlier in the day, the Nikkei crossed 38,000 level for the first time since February 27, hitting 38,004.2 but failed to keep that level throughout the day.

Investors were not confident about the market outlook, said Shuutarou Yasuda, a market analyst at Tokai Tokyo Intelligence Laboratory.

"It's just that their worries about the U.S. tariff impact and the U.S. economic outlook were partially removed. They were not bullish about the market yet, which is why investors sold stocks as the Nikkei rose close to the 38,000 level," said Yasuda.

Defence-related shares, which had rallied on expectations for more defence spending, fell, with IHI 7013.T and Mitsubishi Heavy Industries 7011.T slipping 4.65% and 2.48%, respectively.
