Tokyo - Tokyo stocks rose upon opening Thursday after the Federal Reserve said it would buy more than 1 trillion dollars in bonds, but they ended the morning session lower as the US central bank's move caused the dollar to fall against the yen, hitting exporters' shares.
The benchmark Nikkei 225 Stock Average temporarily rose above 8,000 before falling 49.28 points, or 0.62 per cent, to 7,922.89.
The broader Topix index of all first-section issues also dropped 0.9 points, or 0.12 per cent, to 763.77.
