TOKYO, Sept 22 (Reuters) - The Nikkei average rose 2 percent to a one-week high on Monday, buoyed by financial shares, on hopes for the $700 billion bank bailout proposed by the United States over the weekend to tackle the financial crisis.
Nomura Holdings <8604.T> shot up more than 8 percent after two financial industry sources told Reuters that Japan's largest brokerage has bid for both the Asian and European operations of U.S. investment bank Lehman Brothers <LEHMQ.PK>. [
]"The market mood has brightened thanks to the (U.S. bailout) proposal," said Kenichi Hirano, operating officer at Tachibana Securities.
"Investors are now watching whether it can reverse the course of the situation, because it has the potential to, but few people expect it to actually solve all the problems that we are facing," he said.
The Bush administration asked Congress on Saturday for $700 billion to bail out firms burdened with bad mortgage debt, seeking extraordinary authority as it tackles the worst financial crisis since the Great Depression. [
]But U.S. stock index futures opened lower on Sunday evening, suggesting U.S. stocks may give back some of Friday's massive rally, as investors awaited details of the proposed bank bailout.
The benchmark Nikkei average <
> added 236.04 points to end the morning session at 12,156.90, hitting its highest level since Sept. 12. The Nikkei ended Friday up 3.8 percent, though it shed 2.4 percent for the week.The broader Topix <
> gained 2.2 percent to 1,174.70.Yutaka Miura, deputy manager of the equity information department at Shinko Securities, said gains were capped after an initial rally as the market has recently advanced sharply and before a holiday on Tuesday in Japan.
"In the short term, the market is in a rebound phase due to a series of financial measures, including the strengthening of short-selling regulations," he said.
"But since stocks have jumped so rapidly, it's natural they take a breather."
Blue-chip exporters such as Canon Inc <7751.T> also climbed after a huge relief rally in U.S. stocks on Friday, encouraged by sweeping government measures to rescue the financial system and restore confidence in shaky markets.
In a bid to stabilise markets, U.S. securities regulators joined regulators from other countries in temporarily banning short sales of financial shares.
BANKS GAIN
Japan's top lender Mitsubishi UFJ Financial Group <8306.T> climbed 4.2 percent to 898 yen and No. 2 Mizuho Financial Group <8411.T> gained 4.3 percent to 466,000 yen.
Shares of Nomura jumped 8.5 percent to 1,416 yen.
Last week saw a dramatic reshaping of the financial landscape as AIG <AIG.N> was bailed out, Lehman Brothers <LEHMQ.PK> filed for bankruptcy and Merrill Lynch <MER.N> was forced into partnership with Bank of America <BAC.N>.
Digital camera maker Canon added 3.5 percent to 4,410 yen, while Sony Corp <6758.T> gained 3.3 percent to 3,480 yen.
Honda Motor Co <7267.T> jumped 6.6 percent to 3,550 yen, the top positive contributor to the Nikkei 225, also after the real <BRBY> soared 5 percent before the weekend. The automaker is the top seller in Brazil's massive motorcycle market.
Fellow automaker Suzuki Motor Corp <7269.T> gained 3.9 percent to 2,115 yen on gains in the Indian rupee. India is Suzuki's biggest market.
Trade was moderate on the Tokyo exchange's first section, with 1 billion shares changing hands, almost in line with last week's morning average.
