Rescue services jumped into action early Sunday morning, using helicopters to pluck stranded people from balconies and roofs, and inflatable boats to access residential streets turned into raging rivers, after Japan was lashed by Typhoon Hagibis, the most powerful storm to strike the country in decades.
At least 10 people were killed and 16 were missing as of Sunday morning, and hundreds of thousands were forced to abandon their homes.
Fourteen rivers flooded, the public broadcaster NHK reported, after record-breaking rains. In Nagano prefecture, northwest of Tokyo, a levee burst on the Chikuma river, flooding a wide area of Nagano city.
Another four levees across the flood zone had also collapsed, according to NHK.
