Rescue workers in Japan continued searching for the missing on Wednesday as the death toll from one of the worst typhoons to hit the country rose to 74,.
Public broadcaster NHK said 12 were missing and more than 220 injured after Typhoon Hagibis lashed through the Japanese archipelago at the weekend.
Throughout the eastern half of the main island of Honshu, 52 rivers had flooded over.
Residents in Fukushima prefecture, which has seen the highest number of casualties, were busy dumping water-damaged furniture and rubbish onto the streets. Many elderly remained in evacuation centres, unable to clean up their homes.
In Date city, farmer Masao Hirayama said the water had reached about 2 metres deep in his house, when he and his son were rescued by boat and taken to an evacuation centre.
"I feel down," Hirayama, 70, said, adding that the flood had swept away all his green houses and farming equipment. "All that is left is the land."
Hirayama said he had rebuilt his house in 1989, raising the ground level following a flood in 1986.
Prime Minister Shinzo Abe said the government would spend 710 million yen ($A9.7million) to facilitate disaster relief.
