Typhoon Dujuan has caused widespread destruction across eastern Japan, resulting in 10 confirmed deaths, four missing persons, and 28 injuries following record-breaking rainfall and severe landslides, according to disaster management officials. The storm severely impacted the Tokyo metropolitan area, particularly striking Chiba and Kanagawa prefectures between Monday and Tuesday.
Casualties and Damage Across the Tokyo Metropolitan Area
The Fire and Disaster Management Agency of Japan reported the updated casualty figures at noon local time, confirming fatalities across multiple prefectures. Six people died in Chiba prefecture, three in Kanagawa, and one in Miyazaki. Among the victims, a woman was found dead in Kanagawa, and a man was located inside a submerged vehicle in Chiba, according to local news agency Kyodo. Rescue operations and damage assessments revealed that six fatalities and two missing persons in Chiba resulted directly from severe landslides, as reported by local broadcaster NHK. The disaster management agency recorded damage to 659 homes, including 22 totally destroyed structures, 10 semi-destroyed buildings, 590 flooded homes, and 37 properties suffering partial damage.
Record Rainfall and Emergency Evacuations
The Japan Meteorological Agency (JMA) documented unprecedented precipitation levels during the storm’s passage. Oshima recorded a historic 48-hour rainfall total of 832 millimeters. In response to the escalating danger, local authorities issued evacuation orders for more than 1.9 million residents across six prefectures: Saitama, Ibaraki, Chiba, Tokyo, Shizuoka, and Kanagawa. Kanagawa prefecture accounted for the largest share of displaced residents, with evacuation orders issued for many people.
Transportation and Public Event Disruptions
The severe weather caused widespread disruption to regional transportation networks and major public events. On Monday, airlines canceled approximately 500 flights at Tokyo’s Haneda and Narita airports. Organizers were also forced to alter the schedule for the Tokyo Game Show—Asia's largest video game convention, held in Chiba—requiring the event to close a day early.
