At least 100 people are thought to have died after record rainfall caused flooding and landslides in western Japan.
Over two million peoples have been forced to leave their homes and more than 50 others are believed to be missing, the Japan Times reported.
Since Thursday, parts of western Japan have received three times the usual rainfall for the whole of July, causing rivers to burst their banks.
“We’ve never experienced this kind of rain before,” a weather official said.
Rescuers restarted their search through the mud for any survivors or the bodies of those killed on Monday morning as officials in Okayama prefecture say water levels were gradually receding and that emergency teams may be able to access the worst-hit areas on foot.
Prime Minister Shinzo Abe said on Sunday that rescuers were “working against time” to contain the situation.
“There are still many people missing and others in need of help,” he told reporters.
In the town of Motoyama, on Shikoku island, 583mm (23in) of rain fell between Friday morning and Saturday morning.
The situation may not abate quickly as further rain warnings are in effect, with more than 250mm predicted to fall in some areas by Monday.
Most of the deaths have occurred in Hiroshima prefecture.
