Tokyo  - The Tokyo market opened lower Thursday following Wall Street's overnight plunge, after disappointment spread over the US government's bail-out plan.

The benchmark Nikkei 225 Stock Average lost 186.27 points, or 2.34 per cent, to end morning trading at 7,759.67.

The broader Topix index of all first section issues was also down 14.61 points, or 1.88 per cent, to 763.49.

A wide range of issues were sold at the Tokyo market Thursday after it was closed Wednesday for a national holiday.

The market was hit hard as the US government's bail-out plan for its financial sector failed to revive investor confidence.

On currency markets at 9 am (0000 GMT), the dollar traded at 90.29-34 yen, down from Tuesday's 5 pm quote of 91.33-34 yen. Japanese financial markets were also closed Wednesday.

The euro traded at 1.2863-68 dollars, down from late Tuesday's quote of 1.2894-96 dollars, and at 116.17-22 yen, down from 117.76-80 yen. dpa()
