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

reversed early gains to trade marginally lower on Friday as

declines in Uniqlo-brand owner Fast Retailing ( FRCOF ) erased gains in

technology heavyweights.

The Nikkei was down 0.1% to 39,595.96 as of 0158 GMT, after

rising as much as 0.8% earlier in the session. The index is on

track to lose 0.5% for the week.

The broader Topix was up 0.73% at 2,832.86.

Fast Retailing ( FRCOF ) tanked 6.7% after the company said

on Thursday higher U.S. tariffs would start impacting its U.S.

operation significantly from later this year and it planned to

raise prices to mitigate the blow.

"Investors were worried about Fast Retailing's ( FRCOF ) outlook for

the next fiscal year. Still, gains of technology stocks

supported the index," said Kentaro Hayashi, senior strategist at

Daiwa Securities.

The market also sold stocks as soon as the Nikkei approached

the psychologically important level of 40,000, strategists said.

Chip-testing equipment maker Advantest ( ADTTF ) rose 0.9%

to track a 0.75% gain in the Philadelphia SE Semiconductor Index

overnight.

Air-conditioning maker Daikin Industries ( DKILF ) climbed

2,87%.

Silicon wafer maker Sumco ( SUMCF ) jumped 3.95% to become

the best percentage gainer on the Nikkei.

Bank shares advanced, aiding gains in the Topix, with

Mitsubishi UFJ Financial Group ( MUFG ) and Sumitomo Mitsui

Financial Group ( SMFG ) rising 2.66% each.

Toyota Motor ( TM ) added 1.66%.

Seven & I Holdings ( SVNDF ) rose 3.63% after the convenience

store operator posted a 9.7% rise in quarterly operating profit,

beating analysts' estimates.
