The Japanese meteorological agency warned the typhoon would bring strong winds and downpours, which could trigger landslides and floods as well as lightning strikes and tornados across the nation.
Violent gusts swept away roof tiles on some houses in Kochi city in western Japan.
"There was a big 'bang, bang'. That woke me up," a local elderly man in Kochi told national broadcaster NHK.
Cities in the expected path of the typhoon were already taking measures to mitigate possible danger.
East Japan Railway announced that it would gradually suspend train services in and around Tokyo and end all trains around 8pm (1100 GMT), shortly before the typhoon was to draw near the Japanese capital.
Keep safe guys!
