Typhoon Dujuan forces hundreds of flight cancellations, warnings of record rainfall near Tokyo

Typhoon Dujuan forced the cancellation of at least 275 flights in Japan on Monday and prompted warnings of potentially record-breaking rainfall as the storm moved closer to Tokyo, according to the Japan Meteorological Agency and airline reports.

Flight and transport disruption

Airlines reported large-scale cancellations. Japan Airlines cancelled 120 domestic and 15 international flights, while All Nippon Airways called off 140 domestic flights. Railway operators in Tokyo and neighbouring regions suspended services on some lines.

Warnings of heavy rain and strong winds

The Japan Meteorological Agency (JMA) warned that rain and winds were expected to intensify even before the typhoon’s arrival, and cautioned that total rainfall through Tuesday could exceed the average monthly rainfall for September.

“The total rainfall through Tuesday could exceed the average monthly rainfall for September, resulting in record-breaking heavy rain,” the JMA said.

The agency reported the typhoon’s wind speeds at 144 kilometres per hour while the storm was approximately 110 kilometres from Hachijojima, one of Tokyo’s farthest islands.

Local impacts and event cancellations

Authorities reported that more than 4,000 households in Chiba, near Tokyo, were without power. Local officials and the JMA warned residents of heavy rain and possible landslides.

Major events were disrupted: the final day of the Tokyo Game Show was called off on Monday, a large outdoor music festival in Chiba was cancelled, and a baseball match scheduled in Chiba was also called off.

Emergency response and ongoing risks

With strong winds, heavy rain and transport suspended in places, officials were urging vigilance. The JMA’s warning about rainfall exceeding the monthly average signals a heightened risk of flooding and landslides as the storm approaches.

What to expect next: further intensification of rain and winds before the typhoon’s arrival and continued disruption to flights, rail services and scheduled events.
