TOKYO, Nov 25 (Reuters) - Japan's Nikkei average jumped 4.2 percent on Tuesday, as a surge in U.S. shares on Washington's decision to rescue Citigroup <C.N> encouraged investors to buy equities, with exporters such as Kyocera Corp <6971.T> bought after the yen remained below last week's high.
Another big exporter, Honda Motor Co <7267.T>, rose 5.4 percent to 2,055 yen. Investors shrugged off Honda's plan to build fewer cars in Japan, Europe and North America to reflect an increasingly bleak outlook for sales as the global economic crisis discourages big-ticket purchases. [
]Wall Street soared on Monday, posting its best two-day run since the aftermath of the 1987 stock market crash, as news of the Citigroup bailout spurred an enormous relief rally. [
]"A two-day rally in U.S. shares prompted market players to cover short positions here," said Norihiro Fujito, general manager of the investment research and information division at Mitsubishi UFJ Securities. The benchmark Nikkei <
> rose 335.29 points to 8,246.08 by midday, rebounding from a three-week trough of 7,406.18 hit on Friday.The broader TOPIX index <
> climbed 3 percent to 826.44.Japanese financial markets were closed on Monday for a national holiday.
Trade was light, with 918 million shares changing hands compared to last week's morning average of 932 million. Advancers outpaced decliners by nearly 3 to 1. The stock market rallied strongly in early trade but soon lost its momentum as investors hesitated to chase shares higher, believing the U.S. government's massive bailout of Citigroup does not mean an end to the financial crisis in the United States.
"Investors are likely to start wondering whether the U.S. government may need to rescue other banks, spending more money and boosting the budget deficit," said Yuuki Sakurai, general manager of financial and investment planning at Fukoku Mutual Life Insurance Co.
Shares in major banks rose across the board, following an overnight leap in Citigroup's share price. Mitsubishi UFJ Financial Group <8306.T>, Japan's largest bank, rose 3.5 percent to 509 yen, while Sumitomo Mitsui Financial Group <8316.T> jumped 8.2 percent to 330,000 yen.
Investors picked up exporters on a weaker yen. Kyocera, the world's No.4 solar cell maker, rose 4.4 percent to 4,940 yen, while Advantest Corp <6857.T>, the world's No.1 maker of chip testers, climbed 4.6 percent to 1,193 yen.
The yen traded at 96.70 yen per dollar <JPY=>, up slightly from Monday but keeping some distance from a three-week peak hit beyond 94 yen last week. [
