The storm is heading north of Japan’s third-largest island, Kyushu, and is expected to bring heavy rain throughout the week, the Japan Meteorological Agency (JMA) said on Monday.
About 10 million people in Kyushu were advised to seek shelter in sturdy buildings or move to higher ground before the storm hit Sunday. Such advice is not mandatory and in the past authorities have made efforts to encourage people to leave their homes. On Sunday, Kyushu authorities took the unusual step of issuing a rarely used “special warning” to convey the severity of the threat posed by the storm.
A “large-scale disaster” could also be imminent with major floods and landslides, the JMA warned. “The highest level of vigilance is required for rising water levels and river flooding, landslide disasters and land flooding,” he said on Sunday.
Several prefectures including the cities of Fukuoka and Nagasaki have been without power since the typhoon hit on Sunday, Kyushu Electric power company said. At least 17 people have been injured by the typhoon so far, authorities added.
Nanmadol is expected to travel across central Japan toward Tokyo in the coming days and will retain much of its strength as it moves, experts warned.
Ferry and bullet train services, and hundreds of flights have been canceled across the country due to dangerous weather.
Residents were asked to be vigilant to avoid possible aftershocks.
