Tokyo stocks have clawed back early losses to end 0.50 per cent higher after upbeat Japanese inflation data and as fund managers bought shares to boost their portfolios at the end of the fiscal year.
The benchmark Nikkei 225 index, which opened 0.32 per cent lower on Friday, gained 73.14 points to finish at 14,696.03, while the Topix index of all first-section shares rose 0.82 per cent, or 9.62 points, to 1,186.52.
Friday's performance mirrored the day-earlier session when early losses gave way to gains by the close as bargain hunters scooped up shares and the yen weakened, a plus for Japanese exporters.
