Tokyo  - Stocks bounced back Friday in Tokyo after the yen weakened against the dollar and the US market rose overnight because of its government's measures to help the financial sector.

The benchmark Nikkei 225 Stock Average, which fell below 8,000 Thursday, rose 199.69 points in morning trading, or 2.51 per cent, to 8,149.34.

The broader Topix index of all first section issues was also up 11.07 points, or 1.41 per cent, at 797.48.

On currency markets at 9 am (0000 GMT), the dollar was quoted at 91.17-20 yen, up from Thursday's 5 pm quote of 89.48-50 yen.

A lower yen makes Japanese producers' products cheaper overseas and boosts their foreign earnings.

The euro traded at 1.2787-92 dollars, down from late Thursday's quote of 1.2845-46 dollars, and at 116.60-65 yen, up from 114.94-98 yen. (dpa)
