Rescuers are continuing to search for missing people in eastern Japan, where torrential rains caused flooding and mudslides last Friday.
The disaster killed 10 people in Chiba and Fukushima prefectures. A woman in her 50s and a man in his 30s are unaccounted for.
Authorities say at least 500 homes were destroyed or flooded in Chiba, Fukushima, Ibaraki and Saitama prefectures. Officials are still trying to assess the extent of the damage.
Some of the flooded houses had already suffered damage when Typhoon Hagibis swept through Japan two weeks ago.
