The national weather agency issued a flood and landslide warning Wednesday for the Sea of Japan coast, with heavy rain expected from eastern to western Japan during the day and Thursday.
The Meteorological Agency issued storm warnings for parts of Shimane and Tottori prefectures.
In Matsue, the capital of Shimane, the Iu River reached a level that risked flooding. The two prefectures instructed about 310,000 and 19,000 residents to evacuate, respectively.
There were reports of damage caused by landslides and flooding at multiple locations in Matsue and the city of Izumo, also in Shimane Prefecture, according to the municipal governments. The agency said 75 millimeters of rainfall was recorded in Izumo in one hour on Wednesday.
The municipal government of Matsue postponed COVID-19 vaccinations for some 200 older people scheduled for Wednesday due to the rain.
In Shizuoka Prefecture, record rains have loosened the earth in some locations and increased the risk of disasters similar to a large mudslide that occurred there late last week, the agency said.
The death toll from the mudslide, in the city of Atami in the prefecture, rose to seven on Tuesday, with 27 people remaining unaccounted for.
