TOKYO, Sept 30 (Reuters) - Japan's Nikkei average was flat in cautious trade on Wednesday, with investors hesitant to actively take positions ahead of a series of economic data releases, while Toyota Motor Corp <7203.T> fell following a U.S. recall announcement.
The stock market lost steam after the dollar/yen <JPY=> exchange rate fell below 90 yen, though some exporters such as Honda Motor Co <7267.T> managed to hold on to their gains.
"The yen below 90 yen against the dollar is having a negative impact, while investors are gradually taking a wait-and-see approach as they wait for important economic indicators both in Japan and overseas," said Mitsuo Shimizu, deputy general manager at Cosmo Securities.
Among a raft of economic indicators due this week, the Bank of Japan will issue its tankan survey of corporate sentiment for July-September on Thursday and U.S. jobs data is due on Friday.
"But investors don't want to aggressively sell stocks, either, due to demand and supply concerns as there still could be end-of-month-related buying today," Shimizu said.
In light trade, the benchmark Nikkei <
> inched up 6.58 points to 10,106.78, after rising 0.9 percent the previous day.The broader Topix <
> was flat at 904.40.On Tuesday, the S&P 500 Index <.SPX> shed 0.2 percent as the Conference Board's Consumer Confidence Index for September fell, underscoring concerns about personal finances amid the worst U.S. job market in 26 years. [
] [ ]TOYOTA SOFT, EXPORTERS RISE
Toyota fell 0.8 percent to 3,540 yen after saying it would recall some 3.8 million vehicles because of the risk that a loose floormat could force down the accelerator, a problem suspected of causing crashes that have killed five people. [
]But market players said they weren't too concerned about the impact on the company's stock price, with one saying recalls usually don't have a lasting effect on shares.
NGK Insulators <5333.T> shot up 8.1 percent to 2,065 yen after the producer of insulators for power utilities and high-energy density batteries raised its profit forecasts for the year to March 2010, citing a steady recovery in demand for auto and electronics-related products.
Other exporters climbed, though many trimmed some of their earlier gains. The yen stood around 89.77 yen <JPY=> to the dollar in early Asia trade, after hitting an eight-month high against the greenback at 88.23 yen on Monday.
Many Japanese exporters have set their exchange rate assumptions for the dollar around 90-95 yen for the current fiscal year to March.
The impact of a stronger yen on earnings of exporter companies is a concern for market players as a stronger Japanese currency eats into exporters' profits when they are repatriated.
Honda Motor Co <7267.T> added 1.7 percent to 2,750 yen, while electronics parts maker Kyocera Corp <6971.T> rose 0.7 percent to 8,370 yen and Tokyo Electron Ltd <8035.T> climbed 1.2 percent to 5,750 yen.
Some 723.7 million shares changed hands on the Tokyo exchange's first section, below last week's morning average of 1 billion. Declining stocks outnumbered advancing ones by 830 to 685. (Editing by Hugh Lawson)
