Tokyo - Tokyo stocks opened higher Wednesday on the US dollar's advance against the yen, but gains were capped due to lingering credit concerns.

The Nikkei 225 Stock Average gained 57.4 points, or 0.4 per cent, to 14,405.77.

The broader Topix index of all first-section issues was also up 2.01 points, or 0.14 per cent, at 1,403.99.

On currency markets at 9 am (0000 GMT), the dollar was quoted at 107.87-92 yen, up from Tuesday's 5 pm quote of 107.74-77 yen. A weaker yen helps boost Japanese companies' earnings.

The euro was quoted at 1.5515-20 dollars, almost unchanged from Tuesday's 5 pm quote of 1.5515-18 dollars, and at 167.45-50 yen, up from 167.19-23 yen. (dpa)
