"If the weakening yen trend continues, there will likely be continuous buying in Japan stocks in the midterm," said Hidenori Suezawa, chief strategist at Nikko Cordial Securities.
The benchmark Nikkei gained 1.4 percent, or 148.99 points, to 10,529.76. That was the highest level since its May 14 peak of 10,551.69, which now becomes its next target.

The Nikkei breached the psychologically important barrier of 10,500 yen after the ADP Employer Services report showed US private employers added 297,000 jobs in December, the largest ever gain, adding to evidence the US economy is on a recovery path. The jobs figures come two days ahead of the US government's closely watched and more comprehensive payrolls report for December, prompting economists to raise forecasts for that data.
"Markets will now wait for US payrolls on Friday for confirmation of the strong trend. But investors will then focus more on how the US data will impact the dollar/yen rate," said Hiroaki Osakabe, a fund manager at Chibagin Asset Management.
"Investors have already taken in stride positive news from the US and will now look for new trading factors. After Friday they will immediately shift their focus to the performance of US companies as the earnings season starts next week."

Fuji Heavy Industries, the maker of Subaru vehicles, surged 4.1 percent to 685 yen after Goldman Sachs hiked its rating to "buy" from "neutral" and added the stock to its "conviction buy list". The brokerage said in a report that Fuji's October-December quarter earnings will likely prompt the company to raise its full-year outlook for the fiscal year ending in March.
But Fast Retailing plunged 5.1 percent to 12,400 yen after the firm said on Wednesday that same-store sales at its Uniqlo clothing chain in Japan dropped 15.5 percent in December, marking the fifth straight month of year-on-year declines.
