Tokyo - Tokyo stocks opened higher Wednesday on a weaker yen and overnight rises in the US market.

The Nikkei 225 Stock Average gained 133.69 points, or 1.01 per cent, to 13,318.65. The index rose 3 per cent at the end of Tuesday trading to exceed the 13,000 level for the first time since July 14.

The broader Topix index of all first-section issues was also up 19.01 points, or 1.48 per cent, to 1,306.75.

On currency markets at 9 am (0000 GMT), the dollar was quoted at 107.22-27 yen, up from Tuesday's 5 pm quote of 106.44-47 yen. A weaker yen helps boost Japanese companies' overseas earnings.
