TOKYO, March 23 (Reuters) - Japan's Nikkei jumped 3.4 percent on Monday to post its highest close in seven weeks, with banks including MUFG 8306.T jumping on optimism about U.S. plans to help a strained financial system, while a weaker yen helped exporters.

The news encouraged investors to take more risks, igniting a broad-based rally in Tokyo stocks.
“Investors bet the U.S. government won’t disappoint them again with its measures to stabilise the U.S. financial system,” said Tsutomu Yamada, a market analyst at Kabu.com Securities. “That has prompted market participants to buy back stocks.”
The benchmark Nikkei .N225 gained 269.57 points to 8,215.53, its highest close since Jan. 29.
The broader Topix .TOPX added 3.5 percent to 791.56, its highest finish since Feb. 4.
Hopes for the U.S. plan boosted U.S. stock futures SPc1 by nearly 2 percent.
Many Japanese investors close their books at the end of this month, prompting institutions such as pension funds to buy to prop up stock prices.
“Investors find it hard to sell off stocks now and the Nikkei will likely consolidate around 8,000, at least until the G20 meeting in April,” said Yumi Nishimura, manager at Daiwa Securities SMBC.
Shares of Mitsubishi UFJ Financial Group (MUFG), Japan’s biggest bank, jumped 4.7 percent to 512 yen. It said on Monday it planned to close 50 branches and cut 1,000 jobs to continue slimming down its operations since its 2005 merger, as a tumbling stock market depletes its earnings. [ID:nT168347]

Mitsubishi rose 7.7 percent to 1,323 yen.
Oil and gas field developer Inpex 1605.T climbed 6.7 percent to 730,000 yen.
Exporters gained as the dollar was trading around 96.15 yen JPY=, after falling as far as 93.55 on Thursday. [FRX/] Investors welcome a weaker yen as it boosts exporters' profits when repatriated.
Electronics parts maker Kyocera Corp 6971.T added 3.8 percent to 6,820 yen, while industrial robot maker Fanuc Ltd 6954.T advanced 4.1 percent to 6,890 yen. The two stocks were the top positive contributors to the Nikkei 225.
