Typhoon Tapah, which has injured dozens of people in southern and southwestern Japan, weakened to an extratropical cyclone on Monday in the Sea of Japan, the Meteorological Agency said.
Strong winds continue to hit many areas, and torrential rain was expected in Hokkaido and the Tohoku and Tokai regions.
The agency warned residents in these areas to prepare for violent winds, high waves and heavy rain.
The season’s 17th named storm, which traveled over the sea through Monday morning, caused strong winds that injured 57 in Okinawa and Kyushu over the weekend, according to the Fire and Disaster Management Agency.
One person suffered serious injuries in Miyazaki Prefecture, the disaster agency said. Most of the injuries were not considered serious.
Kyushu Electric Power Co. said blackouts continued to affect six of the seven prefectures on the island of Kyushu and more than 14,000 homes were left without power Monday.
Some air and rail traffic disruption also continued in the region, Kyushu Railway Co. and airlines said.
The extratropical cyclone brought heavy rain to Miyagi, Kochi, Mie and Kumamoto Prefectures the same day.
