Tokyo - Tokyo stocks bounced back Wednesday after Wall Street's overnight rally.

The benchmark Nikkei 225 Stock Average rose 115.35 points, or 1.59 per cent, to 7,383.91.

The broader Topix index of all first-section issues was up 7.58 points, or 1.04 per cent, at 737.86.

Exporters were helped by the US dollar's advance against the yen, as a weaker currency helps boost Japanese companies' earnings.

On currency markets at 9 am (0000 GMT), the dollar traded at 96.52-57 yen, up from Tuesday's 5 pm quote of 95.35-37 yen.

The euro traded at 1.2867-72 dollars, up from late Tuesday's quote of 1.2747-49 dollars, and at 124.25-30 yen, up from 121.54-58 yen. (dpa)
