TOKYO, Sept 12 (Reuters) - Japan's Nikkei share average

hit a record high on Friday, tracking Wall Street's strong

finish overnight, but the gains were limited as the market

turned cautious about the rally.

As of 0152 GMT, the Nikkei rose 0.7% to 44,668.23,

after gaining as much as 1.16% to a record intraday high of

44,888.02 earlier in the session.

For the week, the index is set to rise 3.8%.

The broader Topix rose 0.35% to 3,158.8 and headed

for a 1.7% weekly gain.

"Gains of Japanese equities are small relative to the

strength of Wall Street," said Seiichi Suzuki, chief equity

market analyst, Tokai Tokyo Research Institute.

"That is a sign that investors started feeling that the

market is overheated."

Wall Street's main indexes notched record-high closes on

Thursday as U.S. inflation and jobless data fuelled expectations

that the Federal Reserve will cut interest rates this month.

The S&P 500 climbed 0.85%, while the Nasdaq

gained 0.72% and the Dow rose 1.36%.

The Nikkei's strong rally was partly supported by active

buying of the Nikkei stock futures ahead of the fixing of

special quotation prices, Suzuki said.

The buying of futures slowed after the special quotation,

used to set values on index options and futures, settled earlier

in the session.

The closely watched settlement price, known in Japan as the

special quotation, or SQ, is calculated from the opening prices

of the 225 shares in the Nikkei share average on the second

Friday of the month.

On Friday, Chip-related Tokyo Electron ( TOELF ) and

Advantest ( ADTTF ) rose 2.99% and 1.35%, respectively.

Fibre optic cable maker Fujikura ( FKURF ), a gauge for data

centre investments, gained 1.75%.

Uniqlo-brand owner Fast Retailing ( FRCOF ) rose 1.56%,

providing the biggest boost to the Nikkei.

Technology investor SoftBank Group slipped 0.17%,

giving back some of the 15% surge this week, which added fuel to

the Nikkei's rally.
