LEAD: Tokyo stocks fall as investors secure gains before U.S. jobs data.

TOKYO, Nov. 5 Kyodo

(EDS: ADDING DETAILS AND PRICES)

Tokyo stocks fell Thursday morning as investors secured gains while awaiting U.S. jobs data for fresh cues, and exporters were weighed down as the yen rose relative to the U.S. dollar.

The 225-issue Nikkei Stock Average lost 113.63 points, or 1.15 percent, from Wednesday to 9,730.68. The broader Topix index of all First Section issues on the Tokyo Stock Exchange was down 6.49 points, or 0.74 percent, to 874.78 after briefly touching positive territory.

Decliners were led by pulp and paper, air transport, and securities issues. The only gainers were the mining, consumer finance and banking sectors.

''As in the U.S. market, there are simply no buying incentives today,'' said Masumi Yamamoto, a Daiwa Securities SMBC Co. market analyst. ''Investors are only picking up specific stocks such as Nissan Motor and others with good earnings reports, as well as resource-related issues.''

The Dow Jones Industrial Average managed only modest gains Wednesday after the Federal Reserve's decision to maintain its ultra-easy credit policy, largely as the market expected. A slight drop in the Nasdaq Composite Index triggered selling for gains in hi-tech shares in Tokyo, brokers said.

A weaker U.S. dollar weighed on Japanese exporters, brokers said. The dollar fell from its overnight high in the lower 91 yen zone to the lower 90 yen level at one point in the morning in Tokyo.

The losses in the key stock indexes were also aggravated in late morning trading by selling in the futures market, brokers said.

Investors in Tokyo are avoiding taking major positions ahead of U.S. employment figures due out Friday, Yamamoto said.

Attention is also on an interim earnings report from Toyota Motor Corp. later Thursday.

On the First Section, declining issues outnumbered advancing ones 1,171 to 360, with 143 others ending the morning unchanged.

Among electronics makers, Sony lost 55 yen, or over 2 percent, to 2,550 yen, while NEC fell over 3 percent.

Sanyo Electric, the morning leader in both value and volume terms, plunged 43 yen, or almost 20 percent, to 173 yen, after Panasonic Corp. launched a tender offer Thursday at 131 yen per Sanyo share.

Bucking the trend, oil and gas explorer Inpex climbed 37,000 yen, or almost 5 percent, to 793,000 yen on positive April-September earnings.

Nissan Motor, which raised its annual earnings outlook Wednesday, gained 7 yen, or about 1 percent, to 668 yen. Toyota Motor, which announced its withdrawal from Formula One racing after the 2009 season, ended unchanged at 3,610 yen.

Trading volume on the main section came to 982.65 million shares, up from Wednesday morning's 775.05 million.

The TSE's Second Section index was down 12.13 points, or 0.56 percent, to 2,144.91 on a volume of 65.82 million shares. On the Osaka Securities Exchange, the near-term December Nikkei 225 index futures contract was down 100 points to 9,720.
