Tokyo: Torrential rains have battered a wide swathe of eastern Japan that was hit by flooding and high winds from Typhoon Hagibis two weeks ago, sending rivers to the tops of their banks and prompting evacuation orders for tens of thousands.
At least 82 people were killed when Hagibis lashed central and eastern Japan, with nearly a dozen still missing.
Authorities warned of the chance of further landslides and flooding on Friday, especially in areas hit by levee breaks that have yet to be repaired even provisionally.
Evacuation orders were issued for at least 80,000 people in Chiba prefecture, just east of Tokyo, where rivers were rising precariously close to their banks and authorities warned the rain could continue for a few more hours.
Parts of Chiba were pounded by 86mm of rain in an hour on Friday morning, the third natural disaster to hit the area in the past six weeks.
Much of Chiba lost power, some areas for weeks, in Typhoon Faxai in September and then were hit by heavy rains due to Hagibis.
The rain was expected to pound the Tokyo area until evening and then move north.
Total rainfall in the area around Tokyo was likely to range from 200-300mm by evening, the Japan Meteorological Agency said.
