TOKYO: Japan's Nikkei share average rose on Wednesday, brushing a 12-day high, buoyed by strong earnings for blue chips such as Sony and Sharp and the yen's slide to near two-week lows against the dollar.
The Nikkei ended the day up 0.86 per cent at 22,746.70 after touching 22,775.47, its highest since July 20.
