TOKYO, May 15 (Reuters) - Japan's Nikkei share average

turned lower on Friday, as traders locked in profits on

high-flying tech shares heading into the weekend.

The Nikkei sagged 1.2%, or 768 index points, to

61,886.05 late in the morning session, reversing an earlier gain

of as much as 0.9%.

Chip-testing equipment maker Advantest ( ADTTF ) was the

biggest drag, slumping 5% to shave 310 index points from the

Nikkei. Heavyweight Tokyo Electron ( TOELF ) lost 2.4%, and

Fujikura ( FKURF ) tumbled 7.4%.

On Wall Street overnight, gains for U.S. tech shares lifted the

S&P 500 and Nasdaq Composite to all-time highs.

However, S&P 500 futures pointed to a 0.4% decline in

Asian hours on Friday.

Japan's broader Topix edged down 0.1% to 3,872.67,

flipping from an earlier 1.3% gain that took it to the highest

since February 27, the day it marked a record peak at 3,938.68.

Energy and automaker shares helped support the Topix, with ENEOS ( JXHGF )

climbing 4.5% and Honda ( HMC ) up 7.1%, extending

gains from Thursday, when it pledged at least 800 billion yen

($5.1 billion) in shareholder returns over three years.

For the week, the Topix was on track to rise about 1%,

although the Nikkei was headed for a 1.5% decline.

Compared to the Nikkei, "Topix has stood out this week"

during the peak of the corporate reporting season as "earnings

reports stoke some volatility in the market", said Nomura

equities strategist Wataru Akiyama.

Among the 33 Topix industry groups, 24 fell on Friday.

Nonferrous metals, which includes Fujikura ( FKURF ) and

Furukawa Electric ( FUWAF ), sank 4.6% to be the worst performer.

Of the Nikkei's 225 components, 131 fell and 94 rose.
