TOKYO, Nov 16 (Reuters) - The likely $15.5 billion share issuance by Mitsubishi UFJ Financial Group (8306.T) and Hitachi Ltd (6501.T) is the latest blow to Japan's long-suffering investors, but it won't be the last.

Japanese companies have already raised $40 billion through issuing common stock and convertible bonds this year, tapping a modest share market rebound for much-needed cash after the financial crisis -- but at the same time heavily diluting the holdings of their current shareholders.

The fundraising, mainly from financial firms but including technology, industrial and real estate companies, has put pressure on stock prices across the board and sparked investor concern about more share sales to come.

"This is the biggest factor why Japanese shares lag behind U.S. and European shares," said Takeshi Osawa, senior fund manager at Norinchukin Zenkyoren Asset Management, referring to the fundraising rush.

"It's going to stay that way if we keep seeing these new share issues that suck several hundred billions of yen out of the market each time." <-------------------------------------------------------------- Graphic tracking Japan issuance: r.reuters.com/cyk79f Graphic of issuance by sector: r.reuters.com/fyk79f --------------------------------------------------------------- > Japan's benchmark Nikkei 225 .N225 has risen only 10 percent this year, making it the worst performing stock market among the Group of Seven major industrial nations.

The U.S. Dow Jones Industrial Average .DJI has gained 16 percent, while Britain's FTSE 100 .FTSE is up 19 percent.

Hitachi, Japan's biggest electronics firm by sales, said on Monday it will raise up to 416 billion yen in a share sale, after fees. Shares of Hitachi made their biggest one-day slide in six months after sources told Reuters about the public issue, the company's first in 27 years. [ID:nT155947]

UNCERTAIN OUTLOOK

Hitachi and others are looking to issue shares now out of fear of a market downturn in the near future, said Mitsushige Akino, chief fund manager at Ichiyoshi Investment Management.

"The outlook is uncertain. If they don't raise funds now they could have a tough time doing so in the future," he said.

Japan's economy grew 1.2 percent in the third quarter, the fastest pace in more than two years, but that was partly due to government stimulus. The better-than-expected economic growth also failed to mask signs of weakness in private consumption and factory output. [ID:nT150510]
