Tokyo's Nikkei index climbed to around a two-month high Tuesday morning, supported by gains on Wall Street amid speculation that a likely Republican victory in U.S. midterm elections would make it difficult for Democratic President Joe Biden to go ahead with planned tax hikes.
The 225-issue Nikkei Stock Average rose 352.06 points, or 1.28 percent, from Monday to 27,879.70. The broader Topix index was up 20.87 points, or 1.08 percent, at 1,954.96.
On the top-tier Prime Market, gainers were led by insurance, marine transportation and precision instrument issues.
