Japan’s Silver Week holiday travel has been severely disrupted as Typhoon Dujuan closes in on Greater Tokyo and the Kanto region, affecting domestic and international visitors. Typhoon Dujuan is closing in on Greater Tokyo and the Kanto region, grounding flights, suspending trains, and triggering official landslide and flooding warnings across a stretch of coast during Japan’s peak travel period.
Typhoon Dujuan reached a central atmospheric pressure of 965 hPa as it approached the Japanese coast, with wind gusts of up to 180 km/h. The Japan Meteorological Agency has issued Level 4 landslide and inundation warnings for the Izu Islands and parts of Kanto, with up to 200 millimeters of rainfall forecast for Kanto and 150 millimeters for Tokai in the initial 24-hour period, with subsequent totals forecast to reach 300 millimeters or more in the hardest-hit areas. The northern Izu Islands are under a Level 5 landslide warning. Japan Airlines cancelled 120 domestic and 15 international flights, while ANA cancelled 140 domestic flights at Haneda and Narita. JR East and Tokaido Shinkansen services have implemented precautionary slowdowns and selective line suspensions along coastal routes. The storm hit during Silver Week — one of Japan’s busiest annual holiday travel periods.
For travelers and residents across Greater Tokyo, Typhoon Dujuan’s arrival threatens immediate rail suspensions and airline ground stops during peak Silver Week travel. With over 200 millimeters of rainfall forecast within 24 hours, regional train operators are executing planned precautionary halts. Commuters should verify automated schedule alerts through official transport portals and prepare emergency battery backups before localized suburban drainage systems become overwhelmed.
JMA radar tracking shows Dujuan’s outer rainbands generating localized linear precipitation bands — known in Japanese meteorology as “senjo-kousuitai” — over the Izu Peninsula well before the eye reaches central Honshu. This contributes to documented hazards including heavy rain, flooding, landslides, and overflowing rivers across exposed areas of the Izu Peninsula and Kanto. Japan’s extreme weather resilience infrastructure, including Tokyo’s Metropolitan Area Outer Underground Discharge Channel, is operational ahead of peak storm conditions.
East Japan Railway suspended services on some lines in Chiba, Ibaraki, and western Tokyo, with other operators announcing precautionary service reductions ahead of peak storm conditions.
Are flights and trains operating normally in Tokyo during Typhoon Dujuan? No. Japan Airlines and ANA have cancelled a combined 260 domestic flights and 15 international Japan Airlines flights at Haneda and Narita airports. JR East and Tokaido Shinkansen have implemented precautionary slowdowns and selective line suspensions across coastal Kanto and Tokai routes as heavy rain advisories remain active.
The JMA issues regular track and rainfall advisories as conditions develop. Typhoon Dujuan is forecast to exit northeast Honshu and move into the Pacific, with the JMA providing updates on the projected timeline. Travelers should check airline and rail operator sites before leaving accommodation and follow local evacuation advisories for shelter locations.
