Millions on Alert as Typhoon Dujuan Threatens Tokyo Region With Flooding and Landslides
Millions of people across eastern Japan were placed on alert as Typhoon Dujuan approached the Tokyo metropolitan region, bringing intense rain and powerful winds.
Authorities urged more than 1.9 million people to evacuate or take steps toward evacuation as the storm moved through the Pacific side of Japan. Tokyo, Chiba, Kanagawa, Ibaraki and Shizuoka were among the areas affected by evacuation information at different stages of the storm.
The Japan Meteorological Agency warned that heavy rainfall could trigger landslides and flooding, particularly in areas close to steep slopes and rivers.
The Izu Islands experienced some of the heaviest rainfall. Izu Oshima recorded more than 600 millimeters within 24 hours, while parts of Chiba also received more than 300 millimeters.
The extraordinary rainfall increased the risk of saturated soil collapsing on hillsides. Authorities therefore advised residents in vulnerable areas to move before roads became inaccessible.
A Level 5 landslide warning was issued for northern areas of the Izu island chain, while Level 4 warnings were reported in several parts of the Kanto region. Japanese officials have repeatedly stressed that residents should use local evacuation information and not wait for conditions to become life-threatening.
The storm also created difficulties for people living in Tokyo and surrounding areas. Flooded roads, suspended rail services and cancelled flights made normal travel difficult.
Japan Airlines cancelled 120 domestic flights and All Nippon Airways cancelled approximately 140. East Japan Railway suspended some operations across affected areas.
The weather also affected major public events. The Tokyo Game Show cancelled its Monday programme, while an equestrian eventing competition at the Asian Games was postponed.
The storm’s timing was significant because Japan was observing Silver Week, when many people travel for holidays. The combination of heavy rain and increased passenger movement put additional pressure on transportation services.
Weather officials also warned of the possibility of linear rain bands. These bands can concentrate heavy rainfall over particular areas and may cause sudden flooding even when the storm itself is moving away.
For Tokyo residents, officials recommended avoiding unnecessary travel and staying away from underground areas that could quickly fill with water.
People were also advised not to approach rivers, drainage channels or flooded roads to take photographs or assess damage. Rapidly rising water can create dangerous currents and make roads unsafe even for larger vehicles.
The storm also affected government schedules. Prime Minister Sanae Takaichi delayed her planned trip to New York for the United Nations General Assembly because of the weather.
Emergency services continued monitoring rainfall, river levels and landslide risks as Dujuan moved northeast.
The situation demonstrated why Japanese authorities place strong emphasis on early evacuation. Once heavy rain intensifies, roads can become impassable and emergency response can become more difficult.
Officials continued to advise residents to monitor official announcements and move to safer locations whenever evacuation orders applied to their area.
Although typhoons are a recurring feature of Japan’s weather, the combination of strong winds and exceptionally heavy rainfall can create rapidly changing risks.
With the storm continuing to affect eastern Japan, authorities remained focused on flood prevention, landslide monitoring and keeping residents away from areas where conditions could become dangerous.
