At least six people were killed on Saturday as Typhoon Shanshan moved eastward through Japan, causing heavy rains that inundated wide areas.
These prompted landslide and flood warnings hundreds of kilometers from the storm's center. Footage from state broadcaster NHK showed cars driving up to their tires on flooded roads in the country's southwest and houses with parts of their roofs torn off.
The storm reached Kyushu on Thursday, bringing record rainfall. One person is missing and more than 100 are injured, according to Japan's Fire and Disaster Management Agency.
Kyushu Electric Power said more than 35,000 households were without power in Kagoshima prefecture in southern Kyushu.
At 12:50 p.m. (3:50 p.m. JST), Shanshan was centered in the Pacific Ocean about 300 miles (480 km) southwest of Tokyo, dumping heavy rain as far north as the northernmost tip of Hokkaido, although the storm was downgraded to a tropical depression on Friday.
Wind gusts reached a maximum of 25 m/s (90 km/h). Authorities have issued flood and landslide warnings across the country since the storm began, halting air and rail service, and closing factories.
The storm is expected to weaken to a tropical depression over the weekend, but heavy rains are expected to continue, according to a NHK report.
