Typhoon Dujuan has killed at least four people, injured 22, and left tens of thousands of homes without power in Japan, according to authorities. The storm brought violent winds reaching 144 km/h (89 mph) before moving away from the coast and out into the Pacific, prompting the Fire and Disaster Management Agency to lift or downgrade most heavy rain and landslide warnings across the region.
Landslide Toll and Missing Persons Near Tokyo
The severe weather triggered multiple destructive landslides across Kanagawa and Chiba prefectures near Tokyo. In Yokosuka, Kanagawa prefecture, mud flowing into a home killed a woman in her 60s, according to public broadcaster NHK. Police and firefighters launched search operations for a couple in their 70s.
Local authorities in Chiba confirmed that three people died in a series of landslides that struck the prefecture. Search operations continued for six people missing after torrential rains collapsed homes and blocked roads, according to disaster management officials. Over 460 houses sustained damage during the storm.
Infrastructure Damage and Flight Cancellations
Infrastructure took a heavy hit as the typhoon swept across the capital region. Officials reported that 45,000 households in Chiba remained without electricity on Tuesday, down from the peak of the storm’s impact.
Transportation networks suffered major disruptions. Japan Airlines canceled 135 flights, while All Nippon Airways scrapped 140 flights. Ahead of the storm’s landfall, more than 1.6 million residents in and around Tokyo received non-mandatory evacuation advisories from the Fire and Disaster Management Agency. The severe weather also forced the early closure of one of the world’s biggest video game trade fairs in Tokyo and disrupted select events at the ongoing Asian Games.
Record-Breaking Rainfall and Climate Context
Although Dujuan weakened while tracking northeast, it dumped historic amounts of rain across parts of the Tokyo area. Oshima, an island located approximately 120 kilometers (75 miles) south of central Tokyo, recorded 832 millimeters (nearly 33 inches) of rain over a 48-hour period. That total amounts to more than double the island’s average rainfall for the entire month of September, according to NHK reports. Meanwhile, rainfall in Tokyo’s Edogawa ward reached a record 282.5 millimeters over 24 hours.
Japan frequently experiences strong typhoons in late summer and early autumn. Scientists note that human-driven climate change is intensifying the risk posed by heavy rains because a warmer atmosphere holds significantly more moisture.
