The broader Topix index of all first-section issues also lost 51.07 points, or 5.28 per cent, to trade at 915.84.

On currency markets at 9 am (0000 GMT), the dollar was quoted at 98.17-22 yen, down from Wednesday's 5 pm quote of 99.37-38 yen.

The euro was quoted at 1.2913-18 dollars, up from Wednesday's 5 pm quote of 1.2842-43 dollars, and at 126.77-87 yen, down from 127.61-65 yen. (dpa)
