Seventeen others were feared dead a day after flooding hit a nursing home in a rural area of Kumamoto prefecture, broadcaster NHK reported.
About 50 people were rescued from the home in Kuma Village, some 950 kilometres south-west of Tokyo, Kyodo News reported on Sunday, citing Kumamoto prefectural officials.
Authorities in Kumamoto ordered about 200,000 residents to flee their homes as they were still warning of torrential rains, mudslides, flooding and swollen rivers in the region.
A seasonal rainy front had dumped heavy rains in the prefectures of Kumamoto and Kagoshima since Saturday.
Rainfall of up to 200 millimetres was forecast for southern Kyushu, 150 millimetres for the Tokai region in central Japan and 100 millimetres for northern Kyushu and the south-western island of Shikoku and the Kinki region by Monday morning, according to the Japan Meteorological Agency.
