TOKYO, Feb 19 (Reuters) - Japan's Nikkei share average rose on Thursday, tracking Wall Street's gains in tech shares and buoyed by renewed optimism about Prime Minister Sanae Takaichi's big-spending plan.

The Nikkei .N225 advanced 0.63% to 57,505.93, as of 0037 GMT, while the broader Topix .TOPX rose 0.47% to 3,825.08.

Semiconductor-related shares lifted the Nikkei index the most. Chipmaking equipment maker Tokyo Electron 8035.T climbed 4% and chip-testing equipment manufacturer Advantest 6857.T gained 2.1%.

Takaichi was formally reappointed as prime minister on Wednesday following a historic general election victory earlier this month. She has pledged to increase investment through targeted public spending to boost consumption and revitalise economic growth.

"With all cabinet ministers reappointed, swift policy execution is expected, which is seen as another positive for the stock market," said Ryotaro Sawada, senior analyst at Tokai Tokyo Intelligence Laboratory, in a research note.

The largest percentage gainer in the index was GS Yuasa Corp 6674.T, up 6.1% after the battery maker unveiled plans to build a new lithium-ion battery factory in Japan.
