Japanese shares surged on Wednesday for the first rise in five trading days as market sentiment was buoyed by receding worries about emerging economies, dpa reported. The benchmark Nikkei 225 Stock Average gained 403.75, or 2.7 per cent, to end at 15,383.91 while the broader-based Topix index was up 31.87 points, or 2.6 per cent, at 1,256.18. In Japan on Wednesday, export-linked stocks were bolstered by the yen's fall against major currencies. A weaker yen makes Japanese goods more competitive overseas and improves repatriated revenues. On currency markets at 3 pm (0600 GMT), the dollar traded at 103.36-40 yen, up from Tuesday's 5 pm quote of 102.77-79 yen. The euro was quoted at 141.20-21 yen, up from 140.42-45 yen late Tuesday and at 1.3660-3661 dollars, little changed from 1.3664-3665 dollars.
