At least five people have died and six others remain missing after powerful Typhoon Dujuan swept across eastern Japan, bringing torrential rain, landslides and widespread flooding, authorities said Tuesday.
Japan’s Fire and Disaster Management Agency reported five deaths, including three in Chiba Prefecture, one in neighboring Kanagawa Prefecture and another in Miyazaki Prefecture. The agency also reported 23 injuries, including three people seriously injured, while at least 468 homes had been damaged. Rescue teams continued searching for missing people in areas affected by landslides and flooding.
Dujuan, the 25th typhoon of Japan’s 2026 season, moved northeastward away from the Japanese archipelago and into the Pacific by Tuesday. Although the storm weakened as it moved away, authorities warned that the danger had not completely passed because saturated ground and swollen rivers could still trigger landslides and flooding.
The storm produced exceptionally heavy rainfall across the Izu Islands and the Kanto region. Oshima in the Izu Islands recorded 832 millimeters of rain in 48 hours, the highest amount recorded there for that period since observations began in 1991. The rainfall was more than twice the island’s average rainfall for the entire month of September.
Tokyo also experienced unusually intense rainfall. The Edogawa area recorded record-breaking rainfall, while parts of Chiba and Kanagawa were hit by flooding and landslides. In Kanagawa, rescue workers searched homes affected by landslides on the Miura Peninsula.
The storm also disrupted electricity and transportation. More than 45,000 households in Chiba remained without power on Tuesday, while hundreds of homes were reported damaged. Major airlines canceled more than 270 flights, affecting tens of thousands of passengers, while several railway services around Tokyo were suspended or disrupted.
The storm also affected major events and daily life in the capital. Some events connected with the Asian Games were disrupted, while a major video-game trade fair in Tokyo was forced to close early because of the severe weather.
More than 1.6 million residents in and around Tokyo were urged to evacuate as the typhoon approached, according to Japan’s disaster management authorities. The warnings were issued amid concerns over flooding, landslides, strong winds and overflowing rivers.
The Japan Meteorological Agency had earlier issued its highest-level landslide warning for parts of the Izu Islands as Dujuan approached. Even after the typhoon moved away, officials urged residents to remain cautious because continued rainfall and unstable ground could create additional hazards.
Dujuan comes during a year marked by severe weather events in several parts of the world. Scientists have said that human-driven climate change can increase the risk of extreme rainfall because warmer air can hold more moisture, potentially intensifying rainfall during storms.
For Japan, the immediate focus remains on rescue operations, restoring electricity and transportation services, and monitoring areas where heavy rain has left the ground unstable. Authorities continue to warn residents in affected regions to stay alert for further landslides, flooding and swollen rivers even as Dujuan moves farther into the Pacific.
