The benchmark Nikkei 225 index was up 1.18 percent, or 201.06 points, at 17,212.59 in early trade, while the broader Topix index edged up 1.29 percent, or 16.37 points, to 1,284.83.

"Japanese shares are seen led by purchases on the backdrop of rallies in European and US bourses with... a cheap yen," Mizuho Securities said in a note.

"Gains will likely continue on expectations for an autonomous rebound after sharp drops in recent sessions and expectations for large-scale US economic stimulus."

"On the other hand, worries over the further spread of the new coronavirus in Europe will continue to weigh on the market," it added.

The dollar fetched 107.48 yen in early Asian trade, against 107.64 yen in New York late Tuesday.

In Tokyo, major exporters were higher, with Toyota surging 4.65 percent to 6,661 yen, Sony soaring 6.01 percent to 6,184 yen, and Olympus rallying 6.40 percent to 1,511 yen.

Panasonic was up 0.88 percent at 732.2 yen while construction machine maker Komatsu was up 2.71 percent at 1,627.5 yen.

SoftBank Group was down 8.81 percent at 3,329 yen after a report said the Japanese company may not buy $3 billion of shares in WeWork from existing investors as part of its planned bailout of the US-based co-working facilities provider.

The drop in imports is seen as part of the impact of the coronavirus on economic activities, analysts said.

On Wall Street, the Dow ended up 5.2 percent at 21,237.38.
