Millions Evacuate as Typhoon Dujuan Brings Torrential Rain and Flooding to Japan

Powerful Typhoon Dujuan has brought heavy rainfall, strong winds and flooding to Japan’s eastern regions, prompting evacuation advisories for more than a million people and disrupting transportation across the country.

The storm moved along Japan’s Pacific coast on Monday, September 21, threatening areas around Tokyo, including Chiba and Kanagawa prefectures. Authorities warned residents about the risks of landslides, flash flooding and dangerous winds as the weather system intensified.
According to reports from Japanese media, at least two people died after heavy rainfall triggered landslides, while others remained missing. In Kanagawa, emergency crews carried out search operations following reports of homes being struck by mud and debris.

The Japan Meteorological Agency issued severe weather warnings and urged residents in affected areas to remain vigilant. Some warnings were later downgraded, although dangerous conditions continued in parts of the Izu Islands and other coastal regions.
The storm also caused widespread disruption to daily life. More than 50,000 households experienced power outages, while hundreds of flights were cancelled and some railway services suspended. Businesses and event organizers were forced to change their plans as heavy rain affected transportation and public safety.

Major events, including activities connected to the Tokyo Game Show and outdoor festivals, were disrupted by the weather. The storm also affected preparations and scheduling during Japan’s Silver Week holiday period.
As Typhoon Dujuan moved northeast away from the coast, officials continued to monitor rainfall and the potential for additional flooding and landslides. Residents in vulnerable areas were advised to follow local evacuation guidance and stay informed about changing weather conditions.

The storm highlights the continuing risks Japan faces from powerful tropical weather systems, particularly in densely populated regions where heavy rainfall can quickly overwhelm infrastructure and threaten communities.
