Typhoon Dujuan has moved past Japan but left behind record-breaking heavy rainfall in the Kanto region and the Izu Islands, causing landslides and floods that have resulted in at least two deaths and several missing persons.
On 22 Sep 2026 GMT+7, the Japan Meteorological Agency warned residents in the Kanto area and Tokyo's islands to closely monitor landslides and river overflows, even though Typhoon "Dujuan" had passed through Japan after bringing heavy rain that caused landslides and flooding in multiple areas.
The Meteorological Agency reported that Oshima city in the Izu Islands of Tokyo recorded accumulated rainfall of 832 millimeters over 48 hours until Monday, more than twice the average monthly September rainfall. In Yokosuka city, Kanagawa Prefecture, multiple landslides occurred, resulting in the death of a 60-year-old woman after mudflow entered her home. Police and firefighters are searching for a married couple in their 70s whose fate remains unknown.
Meanwhile, in Miura city, Kanagawa Prefecture, mudflows inundated a two-story residential building, causing a 20-year-old woman to go missing. Another woman, aged 30 and located about 2 kilometers away, is also still missing.
Additionally, in Kamakura city, flooding turned roads into river-like conditions, and hotel staff had to urgently pump water out of rooms. Chiba Prefecture was also affected by heavy rain. In Sodegaura city, a woman driving into a landslide area was hospitalized with minor injuries. A worker operating heavy machinery to clear debris from the road fell into a bamboo grove and later died.
Japanese authorities have urged the public to remain alert for landslides and rising or overflowing rivers, and have warned about strong winds and high waves in areas still affected by unstable weather conditions.
