Japan's economy shrank less than initially estimated in the first quarter but the broad impact from the coronavirus crisis is still expected to send the country deeper into recession.

A series of recent April data including exports, factory output and jobs figures suggested Japan is facing its worst postwar slump in the current quarter as the outbreak forced people to stay at home and businesses to close globally.

The world's third-largest economy shrank an annualized 2.2 percent in January to March, revised data showed on Monday, less than the 3.4 percent contraction indicated in a preliminary reading and compared with a median market forecast of a 2.1 percent drop.
