Tokyo stocks jumped 2.28 per cent on Wednesday to close at their highest level in nearly three years thanks to a weaker yen and receding concerns over Europe's debt crisis. The benchmark Nikkei 225 index closed up 247.23 points at 11,113.95, its highest finish since April 2010, while the Topix index of all first-section shares rose 1.51 per cent, or 13.91 points, to 934.67.
