TOKYO, Jan 24 (Reuters) - Japan's Nikkei average rose 1.4 percent on Thursday after Wall Street rebounded on optimism that a rescue for U.S. bond insurers may be in the offing, with proposals to support the Tokyo stock market also giving a boost.
Exporters such as Canon Inc <7751.T> surged, while battered property shares were snapped up by investors seeking bargains. Banks gained on strength in their U.S. peers.
Shares briefly rose over 2 percent after sentiment was buoyed by news that members of Japan's ruling Liberal Democratic Party are debating emergency steps to help the stock market, including tax exemptions on dividend income and capital gains.
A draft of the proposals included a call for the Bank of Japan to cut interest rates back to zero and return to quantitative easing, in which the banking system is flooded with excess cash. It also said the government should consider establishing a sovereign wealth fund.
Market participants were sceptical.
"If they could carry out these proposals it would be incredible, but I don't think anybody in the market believes they really will. After all, they'd lose a lot of tax money and how would they keep the government going then?" said Masayoshi Okamoto, head of dealing at Jujiya Securities.
"This is positive not for its content but for the message it sends, that the government and Bank of Japan are ready to do something aggressive," said Okamoto.
Nearly all of the Nikkei's gains were based on short-covering in the wake of Wall Street's rebound, players said.
The Dow Jones industrial average <
> surged nearly 300 points on optimism that a government plan to rescue ailing bond insurers is taking shape and could prevent more huge credit losses, while confidence is growing that aggressive interest rate cuts by the Federal Reserve could help stabilise the economy."Wall Street was a roller coaster yesterday, but the chance of support for bond insurers is quite positive, since it shows authorities may respond faster than to the subprime mortgage crisis," said Takashi Ushio, head of the investment strategy division at Marusan Securities.
The benchmark Nikkei was up 1.4 percent at midsession at 13,013.92 after earlier rising as high as 13,134.77, a gain of more than 2 percent.
The broader TOPIX index <
> was up 1.9 percent at 1,273.89 after earlier also surging above 2 percent.PROPERTY POSITIVE
Property-related shares, which have been sharply sold this month, surged on buying by investors attracted by their valuation as well as technicals suggesting a rebound.

Mitsubishi Estate Co Ltd <8802.T>, the second-largest property firm, gained 7.3 percent to 2,500 yen and Tokyu Land Corp <8815.T> was up 7.6 percent at 803 yen.
