Typhoon Dujuan: Japan warns of flood and landslides as powerful typhoon approaches
A powerful Typhoon Dujuan is bearing down on Japan’s eastern coast, triggering emergency alerts, evacuations, and widespread disruption as authorities warn of record rainfall, floods, and landslides around Tokyo and the Kanto region. The storm—Japan’s 25th of the year—has led to hundreds of flight cancellations, suspended rail services, and logistical challenges for events tied to the Asian Games still underway in Nagoya. Officials have raised multiple alert levels, ordered evacuations for vulnerable residents, and urged people to stay indoors and heed warnings. With conditions expected to intensify through Tuesday, the focus is on safeguarding residents, coordinating emergency responses, and managing the knock-on effects on transportation and public events. The situation remains fluid as preparations continue and the public braces for possible further impacts.
