TOKYO, June 24 (Reuters) - Japan's Nikkei share average

eked out gains on Monday after a mixed session on Wall Street

last Friday, with export-related stocks getting some support

from a weaker yen.

The S&P 500 and Nasdaq closed slightly lower on Friday while

the Dow ended almost flat, with technical factors and a second

day of declines for Nvidia ( NVDA ) weighing on the market.

"What we're seeing is a repeat of what happened into the end

of May, where there was selling from these real money fund

managers to get back to benchmark weightings, particularly

things like the Nasdaq and Nvidia ( NVDA )," said Tony Sycamore, a market

analyst at IG.

That, in turn, weighs on the Nikkei, he added.

Japanese chip shares, in particular, which have been some of

the Nikkei's strongest performers over the past year, were

finding momentum hard to come by on Monday as a result.

The Nikkei rose 0.24% to 38,689.22 by the midday

break. The broader Topix was up 0.26% at 2,731.69.

Export-related stocks advanced as the yen weakened towards

the 160-per-dollar level. A weaker yen helps boost Japanese

exporters' overseas earnings when repatriated and increases

their competitiveness.

The Nikkei has traded in a narrow range in recent months,

with the index on track for a less than 1% gain this month after

a flat May.

"Since April, it's been in a period of consolidation", as

investors wait out currency and bond market volatility and look

for clarity from the Bank of Japan, IG's Sycamore said.

Among individual stocks, Toyota Motor ( TM ) rose 2.3%

and was among the top percentage gainers on the Nikkei. Soy

sauce maker Kikkoman ( KIKOF ) and Chugai Pharmaceutical ( CHGCF )

both climbed about 3%. SoftBank Group ( SFTBF ) inched up 0.6%.

Online service platform operator Mercari ( MRCIF ) was at the

bottom with a 4.1% decline.

Among chip-related shares, Tokyo Electron ( TOELF ) edged

down 0.1%, Disco Corp ( DISPF ) fell 0.8%, and Shin-Etsu Chemical ( SHECF )

slipped 0.1%. Advantest ( ADTTF ) edged up 0.1%.
