Japan's Nikkei stock average edged up 0.4 percent on Wednesday to close at a two-week high, with short-covering buoying the market as the yen fell against the dollar while metals shares rose after gold hit a record high.
Silicon wafer maker Sumco Corp dragged on the market as it plunged nearly 9 percent after swinging to an operating loss.
New funding plans by the Bank of Japan to support the economy announced after the close on Tuesday were greeted with disappointment although not enough to send the market lower.
Market players said they were now focusing on a meeting between BOJ governor Masaaki Shirakawa and Prime Minister Yukio Hatoyama set for later on Wednesday.
The BOJ announced that it would offer 10 trillion yen ($115 billion) in new short-term funds, but stopped short of more aggressive measures to support the economy.
"The market wasn't happy after the announcement, but short-covering is preventing further falls — partly on the weaker yen, and partly on gains by Chinese shares," said Noritsugu Hirakawa, a strategist at Okasan Securities.
"Plus hopes that something may emerge from the meeting today between Shirakawa and Prime Minister Hatoyama are making it hard to sell."
The benchmark Nikkei inched up 36.74 points to 9,608.94 to close at its highest level since Nov. 18. The broader Topix rose 0.1 percent to 858.74.
Shirakawa said the new funding operation the central bank announced on Tuesday could be considered quantitative easing in a broad sense.
The BOJ said it would pump more cash into the banking system after an emergency meeting which it called in the face of political pressure to help fight deflation and avert recession before upper house polls next year.
"It's not as if the market didn't welcome the BOJ's move at all because we can still expect some impact as the central bank is set to supply money," said Yutaka Miura, a senior technical analyst at Mizuho Securities.
"But the meeting's result was less than the market had expected and its effectiveness appears to be also limited."
