Tokyo`s Nikkei stock index rose 1.17 percent by the lunch break Monday, reversing early losses in the wake of a pledge by world leaders to restore global growth and news that Japan is in recession.

The benchmark gained 98.80 points to 8,561.19, after climbing 2.72 percent on Friday.

Official data released just before the opening bell showed Japan`s economy contracted 0.1 percent in the three months to September, shrinking for a second straight quarter.
