Japan has deployed tens of thousands of troops and rescue workers after one of the strongest storms in years hit, killing at least 18 people.
Typhoon Hagibis made landfall south of Tokyo on Saturday, moving north and bringing severe flooding.
Thirteen people are missing from the storm, public broadcaster NHK said.
In central Nagano prefecture, water surrounded Japan's famous bullet trains while helicopters plucked stranded residents from rooftops.
A total of 27,000 military troops and other rescue crews have been deployed in relief operations, authorities said.
