Tokyo stocks rallied Wednesday after the Bank of Japan announced that it has decided to change the framework of its bond-buying program and will not take interest rates further into negative territory, while the yen's fall also boosted sentiment.

The 225-issue Nikkei Stock Average ended up 315.47 points, or 1.91%, from Tuesday at 16,807.62. The broader Topix index of all First Section issues on the Tokyo Stock Exchange finished 35.70 points, or 2.71%, higher at 1,352.67, according to Japan's (Kyodo) News Agency.

Every industry category on the main section gained ground, led by banking, insurance and securities house issues.
