Typhoon Dujuan left four people dead and 22 injured in Japan after lashing the country’s Pacific coast with torrential rain, triggering destructive landslides, and disrupting transportation and power supplies across the greater Tokyo area, according to Asharq Al-Awsat. As the storm moved away from Japan’s coast and out into the Pacific, authorities were able to lift or downgrade most heavy rain and landslide warnings, according to Malay Mail.

The Fire and Disaster Management Agency reported that three fatalities occurred in Chiba Prefecture and one in Kanagawa Prefecture, both located near Tokyo, according to Asharq Al-Awsat. In Sodegaura, Chiba, a 51-year-old man working to restore a damaged road died at a hospital after a landslide engulfed him and the hydraulic excavator he was operating, police stated in a report by Kyodo News. Additional landslide victims in Chiba included a woman in her 70s in Kamogawa and a woman in her 80s in Sanmu, who died when their homes collapsed, as reported by The Japan Times. In Yokosuka, Kanagawa Prefecture, a 64-year-old female resident died after mud and debris flowed into the first floor of her two-story home, according to The Japan Times and NBC News.
Search Operations and Ongoing Disasters
Police, firefighters, and the Self-Defense Forces conducted search operations in Chiba and Kanagawa prefectures for six people reported missing following landslides, according to The Japan Times and Asharq Al-Awsat. In Yokosuka, a couple in their 70s went missing about a kilometer away from where the first landslide struck after mud hit their home, according to The Japan Times. In the neighboring city of Miura, Kanagawa Prefecture, a landslide hit an apartment building, leaving a woman in her 20s and another woman unaccounted for, as noted by Kyodo News and The Japan Times.
The Japan Meteorological Agency had issued its highest-level landslide special warning for parts of the Izu Islands, including Oshima, before the warnings were later downgraded, according to The Japan Times and Malay Mail. The Cabinet Office applied the Disaster Relief Act to 25 municipalities following the heavy rains, according to The Japan Times. Over 460 houses were damaged across the region, according to Asharq Al-Awsat.
Record Rainfall and Infrastructure Impacts
Typhoon Dujuan dumped record-breaking rainfall across parts of the Tokyo area, with Oshima recording 832 millimeters of rain over a 48-hour period—more than double its average rainfall for the entire month of September, according to public broadcaster NHK reports cited by Asharq Al-Awsat. In Tokyo’s Edogawa Ward, rainfall reached 282.5 millimeters over 24 hours, according to Asharq Al-Awsat.
The severe weather caused widespread infrastructure disruptions, leaving about 45,000 households without electricity in the region, with the vast majority of blackouts concentrated in Chiba Prefecture, according to Tokyo Electric Power Grid data reported by The Japan Times and NBC News. Transportation networks were heavily impacted during a five-day holiday period, forcing the cancellation of more than 270 flights by All Nippon Airways and Japan Airlines—affecting roughly 40,000 travelers primarily at Tokyo’s Haneda airport—while JR East suspended services on several local lines, according to Kyodo News. The storm also forced the early closure of major events, including the Tokyo Game Show video game convention and concerts at the Rock in Japan music festival, according to BBC News.
