TOKYO (Reuters) - Japan's Nikkei share average rose to a one-week high on Wednesday, helped by a second-straight day of gains on Wall Street as investors bet that the Federal Reserve would temper worries about an imminent roll back of its stimulus programme.

The Nikkei <.N225> rose 2.0 percent to 13,265.53, while the Topix <.TOPX> gained 2.1 percent to 1,108.60.
