TOKYO, Nov 11 (Reuters) - Japan's Nikkei share average

rose on Tuesday, with tech shares leading the advance after Wall

Street peers rallied overnight on optimism that an end was in

sight to the U.S. government shutdown.

The tech-heavy Nikkei climbed 0.7% to 51,269.56

about an hour into the trading day, and earlier touched a

one-week high of 51,513.16.

Artificial intelligence-focused startup investor SoftBank

Group jumped 4.8%, single-handedly contributing 193

index points of the Nikkei's total 406-point advance. The

company will report earnings after the close of trading.

Under the surface, though, the Nikkei was split, with 121 of

its 225 components rising, 98 falling and six trading flat.

The broader Topix added a more muted 0.3% to

3,327.93.

"Chip- and data-center stocks certainly stand out," said

Maki Sawada, a strategist at Nomura Securities.

"But even within that group, there are exceptions."

The nearly even split between gainers and losers "shows that

there's no single, big driving force, and some traders are

taking the opportunity to lock in profits", she said.

Chip-making machinery manufacturer Tokyo Electron ( TOELF )

added 0.3%. Chip-maker Renesas advanced 3.2%.

Chip-testing equipment maker Lasertec ( LSRCF ) jumped 3.9%,

but larger peer Advantest ( ADTTF ) eased 0.4%.

Sony Group ( SONY ), which will also report earnings after

the close of trading, added 0.4%.
