Japan’s Fire and Disaster Management Agency confirmed two deaths from landslides triggered by Typhoon Dujuan in the Kanto region. In Yokosuka city in Kanagawa prefecture, a woman in her 60s died after her home was inundated by mud flowing from a landslide, according to the Yokosuka City Fire Department. A 51-year-old man operating heavy machinery to clear road debris was killed by a separate landslide in Sodegaura city in Chiba prefecture, local police told Kyodo News.
Public broadcaster NHK reported that four other people remained missing following additional landslides in the area as of Tuesday morning. The Japan Meteorological Agency recorded 832 millimetres of rain over 48 hours on Oshima island south of Tokyo, more than double the island’s average September rainfall total. This deluge prompted the agency’s highest-level landslide warning for parts of the Izu island chain and led local officials to open multiple evacuation shelters.
Nearly two million residents received evacuation orders or advisories as the storm approached on September 21, according to tallies from prefectural authorities. Mayors in cities such as Kamakura warned that flooded roads made car travel dangerous and urged residents to seek higher ground. Flooding also affected parts of Ichikawa city east of Tokyo and led to submerged homes in multiple municipalities across Chiba prefecture.
Tokyo Electric Power Company stated that more than 46,000 households in Chiba remained without electricity early on September 22. The outages followed gusts reaching 194 kilometres per hour that accompanied sustained winds of 130 kilometres per hour, measurements published by the Japan Meteorological Agency showed. Crews worked to restore power but faced obstacles from fallen trees and ongoing heavy rain in affected zones.
Japan Airlines cancelled 135 flights while All Nippon Airways grounded 140 as the typhoon disrupted operations at Haneda and Narita airports, company statements indicated. Several rail lines in Chiba, Ibaraki and western Tokyo suspended services, including some conventional routes operated by East Japan Railway, according to transport ministry updates. The storm also forced the early closure of the Tokyo Game Show on its final day, organisers announced amid safety concerns.
The Japan Meteorological Agency noted that Dujuan had weakened as it tracked northeast away from the coast toward the Aleutian Islands by Tuesday. This latest event adds to a series of powerful typhoons that have disrupted events including the Asian Games hosted in Japan this season, various regional reports observed. Authorities continued to monitor rivers and landslide-prone areas even after most warnings were downgraded.
