Several areas have registered record levels of precipitation since torrential rainfall began lashing the country on Thursday, and 20 prefectures are on alert - three of them on the highest possible alert -- Gifu, Ehime, Kochi -- for overflowing rivers and disasters related to landslides and mudslides.
A 54,000-member team, including soldiers, police officers and firefighters were involved in the rescue efforts, for which 41 helicopters have also been deployed, Suga added.
Authorities have ordered the evacuation of over four million people in southwestern Japan.
The rains are the deadliest to hit Japan since August 2014, when 77 people died in Hiroshima.
