Stocks rose in Tuesday morning trading in Tokyo as investors bought battered shares from the previous day's gains and the US dollar advanced against the yen, dpa reported.
But gains were capped in the wait-and-see mood before the US government's release of its bank rescue plan.
The benchmark Nikkei 225 Stock Average went up 15.51 points, or 0.19 per cent, to 7,984.54.
The broader Topix index of all first section issues was also up 3.4 points, or 0.44 per cent, at 782.3.
On currency markets at 9 am (0000 GMT), the dollar traded at 91.30-35 yen, up from Monday's 5 pm quote of 91.16-18 yen.
The euro traded at 1.2960-65 dollars, up from late Monday's quote of 1.2895-97 dollars, and at 118.35-40 yen, up from 117.55-59 yen.
