Tokyo's benchmark Nikkei index rallied more than 1.1% on Monday on bargain-hunting with investors still optimistic for a new US stimulus package.
The Nikkei 225 index gained 1.11%, or 260.50 points, to close at 23 671.13, while the broader Topix index rose 1.25%, or 20.29 points, to 1 637.98.
"Hopes for a new US stimulus package are still sustaining sentiment," while investors bought on dips following two days of declines, said Toshikazu Horiuchi, a broker at IwaiCosmo Securities.

China-related shares faced modest pressure after Beijing released figures showing the world's number two economy expanded at a slower rate than expected in July-September.
