Tokyo - Tokyo stocks opened higher Wednesday on optimism over the US economy and a weaker yen.

The Nikkei 225 Stock Average gained 130.23 points, or 0.93 per cent, to 14,179.49.

The broader Topix index of all first-section issues was also up 21.5 points, or 1.56 per cent, at 1,398.89.

On currency markets at 9 am (0000 GMT), the dollar was quoted at 104.90-95 yen, up from Friday's 5 pm quote of 104.72-74 yen. Japanese financial markets were closed Monday and Tuesday for the Golden Week national holidays.

A weaker yen makes Japanese products cheaper abroad and helps boost earnings of Japanese companies.

The euro was quoted at 1.5515-20 dollars, up from Friday's 5 pm quote of 1.5465-67 dollars, and at 162.79-84 yen, up from 161.96-162.00 yen. (dpa)
