The typhoon is coming "very close to the Pacific coast" of eastern Japan, centring on Tokyo, and is expected to move towards northern provinces from late Wednesday and early Thursday, the meteorological agency said.

"There are also risks that it may make landfall," it said, warning it could dump 350 millimetres (13.7 inches) of rain over the greater Tokyo region over the 24 hours by Thursday noon.
