Tokyo shares closed up 1.94 percent Wednesday, rebounding from losses over the first two trading days of the new year, as Wall Street provided a strong lead while the yen eased against the dollar.
The benchmark Nikkei-225 index ended 307.08 points higher at 16,121.45, and the Topix index of all first-section shares rose 1.79 percent, or 22.98 points, to 1,306.23.

Investors are awaiting the release of minutes from the Federal Reserve's most recent policy meeting later Wednesday to see if another cut in its stimulus could be on the cards.

Traders are also eyeing key US jobs data due later this week for signs of a firming recovery in the world's biggest economy.
"There is a risk the US non-farm payrolls data awaited later this week will disappoint," an equity trading director at a foreign brokerage told Dow Jones Newswires.
"But the opposite scenario -- a strong report -- could also generate fears of an acceleration in the Fed's tapering programme, from which a rise in interest rates could prove unfriendly to equity markets."
On Wednesday the Nikkei was lifted by a weaker yen, with the dollar buying 104.89 yen against 104.69 yen in New York trade.
