* Nikkei gains 1.5 pct, trade moderate before BOJ and Fed
* Banks cheered by overseas news but uncertainty remains
* Exporters climb as yen edges down against dollar
* Hitachi up after reshuffle, restructuring announcement
By Elaine Lies TOKYO, March 17 (Reuters) - The Nikkei stock average rose 1.5 percent on Tuesday, as banks like Mizuho Financial Group <8411.T> extended gains on improved sentiment about the global financial system and hopes for fresh policy steps from Japan's government.
Exporters also advanced on a weaker yen, but gains were capped after Wall Street snapped a four-day rising streak, hurt when American Express Co <AXP.N> said the number of people struggling to make credit card payments had grown.
Hitachi Ltd <6501.T> rose 1 percent, erasing earlier losses, after tapping a power business veteran as its new CEO and saying it would split-off its ailing automotive and consumer units as it races to restructure its sprawling operations. [
]Market analysts said that while the Nikkei is unlikely to test a 26-year low just under 7,000 any time soon, much uncertainty lingers.
Bank of America <BAC.N>, Citigroup <C.N> and JPMorgan Chase & Co <JPM.N> have said they were in the black for this year, while British bank Barclays Plc <BARC.L> said on Monday it made a strong start to 2009. [
]"We still can't really relax, since we won't know the full details of their profits until quarterly results come out, and there's still a lot of uncertainty," said Takashi Ushio, head of the investment strategy division at Marusan Securities.
"But they do seem to have pulled back from the worst danger."
Expectations for fresh Japanese government policies, including possible stock-buying steps and possible purchases of subordinated debt issued by banks to help bolster their capital, were providing support. [
] But April and May could be rough months for equities markets as companies in both nations start announcing results. The Japanese business year ends on March 31."We're going to have to see results to really know what's going on, both in Japan and America, with investors focusing mainly on forecasts for the next business year -- and this could prove very bad," said Nagayuki Yamagishi, strategist at Mitsubishi UFJ Securities.
"It's a question of whether current hopes will be betrayed, or not."
The benchmark Nikkei <
> gained 114.67 points to 7,818.82, while the broader Topix < > rose 1.5 percent to 752.59.BANKS FORGE UPWARDS Banks took heart from rises by Bank of America and Citigroup <C.N>, but overall trade was moderate as investors waited for results from two-day meetings of the Bank of Japan and the Federal Reserve, both of which start on Tuesday.
Mitsubishi UFJ Financial Group <8306.T> rose 3.4 percent to 456 yen and Mizuho Financial Group <8411.T> gained 3.7 percent to 196 yen. Sumitomo Mitsui Financial Group <8316.T> rose 5 percent to 3,170 yen.
The dollar edged up 0.2 percent to 98.38 yen <JPY=>, supporting the exporters. [
] <FXNEWS>Honda rose 2.2 percent to 2,295 yen and Canon Inc <7751.T> gained 1.2 percent to 2,625 yen. Toyota Motor Corp <7203.T> rose 3.1 percent to 3,030 yen. The Nikkei business daily reported that the company plans to slash the price of its current generation Prius hybrid car by 19 percent to 1.89 million yen ($19,250), matching rival Honda's hot-selling Insight.
Hitachi, which is facing a $7.1 billion loss, rose 1.1 percent to 266 yen. "While the new management team and restructuring proposal are an improvement in terms of speed, Hitachi's core businesses are unclear and measures to improve its sector standing in our view look weak," UBS analyst Hitoshi Shin wrote in a note to clients.
"No earnings improvement is likely aside from that due to improved external conditions."
Still, UBS maintained a "neutral" rating on the stock and kept the price target unchanged at 260 yen after the news.
Trade was moderate on the Tokyo exchange's first section, with 954 million shares changing hands, compared with last week's morning average of 1 billion.
