The tropical storm, sweeping through the southernmost Japanese prefecture of Okinawa, is expected to head towards Amami Oshima island on Tuesday.
Japan’s southernmost region of Okinawa was bracing for the arrival of Typhoon Jangmi on Monday, a storm system expected to bring severe rain and winds.
The Japan Meteorological Agency said that the Okinawa Islands, the Sakishima Islands and the Daitō Islands, face high risks of landslides and high waves.
The agency predicts gusts of up to 162km/h, before moving on to the Amami region on Tuesday.
Residents have been urged to avoid nonessential travel and stay on high alert, while elderly people and others who may need more time are warned to evacuate in parts of both the Okinawa and Amami regions.
Heavy rain is expected on Wednesday in the coastal Kanto region, which includes Tokyo.
More than 400 flights mainly scheduled by All Nippon Airways in and out of Okiwana have been cancelled due to the incoming storm.
According to the Japan Meteorological Agency, this is the sixth Typhoon of the year.
In 2025, Japan experienced a total of 27 typhoons, higher than the average of 25.
