Tokyo stocks surged on Wednesday as a rise in prices for crude oil and a comparatively weak yen sent a broad swathe of issues higher including energy-linked shares and the market's key exporters.
The 225-issue Nikkei Stock Average climbed 421.03 points, or 2.64 percent, from Tuesday to 16,349.82, Xinhua news agency reported.
The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, jumped 31.63 points, or 2.43 percent, to 1,330.98.
All industry categories on the main section advanced, with insurance, mining and banking-linked shares comprising the morning's notable winners.
