Nearly 200,000 people in western Japan were urged to evacuate on Saturday as authorities warned of landslides and floods while the remnants of a tropical storm trickle over the country.
The Japan Meteorological Agency said "warm, moist air... was causing heavy rainfall with thunderstorms in western Japan" partly due to Kong-rey, which was downgraded to an extratropical low-pressure system from a typhoon.
The city of Matsuyama "issued the top-level warning, urging 189,552 residents in its 10 districts to evacuate and immediately secure safety," a city official told AFP.
While the evacuation was not mandatory, Japan's highest-level warning is typically issued when it is extremely likely that some kind of disaster has already occurred.
Forecasters warned that landslides and floods could affect western Japan on Saturday and eastern Japan on Sunday.
Due to rain, shinkansen bullet trains were briefly suspended between Tokyo and southern Fukuoka region in the morning before resuming on a delayed schedule.
Kong-rey smashed into Taiwan on Thursday as one of the biggest storms to hit the island in decades. It claimed at least two lives and knocked out power to tens of thousands of households.
Scientists say human-driven climate change is intensifying the risk posed by heavy rains because a warmer atmosphere holds more water.
