Japan Airlines and All Nippon Airways cancel 275 flights as Typhoon Dujuan nears Tokyo

Disruption overview

Typhoon Dujuan has prompted Japan Airlines and All Nippon Airways to cancel 275 flights scheduled for 21 September 2026 as the storm makes a close pass of Tokyo. The cancellations include 135 Japan Airlines services, among them 15 international flights, and 140 domestic flights operated by All Nippon Airways, with routes in and out of the capital affected alongside regional services across Japan. Heavy rain and gusts of up to 144 km/h have also disrupted rail travel and left more than 4,000 households in Chiba without electricity. Because the disruption is weather-related and outside the airlines’ control, financial compensation is unlikely, but airlines should still provide care and assistance if your journey is affected.

Disruption details

On 21 September 2026, Japan Airlines and All Nippon Airways canceled 275 flights as Typhoon Dujuan moved toward the Tokyo metropolitan area, bringing major disruption to air travel at the start of the week.

For passengers, this meant sudden changes to travel plans, longer waits, and uncertainty before they even reached the airport. The affected services included domestic and international flights linked to Tokyo’s two airports, as well as regional routes across Japan.

The cancellations announced so far break down as follows:

• Japan Airlines canceled 120 domestic flights and 15 international flights.

• All Nippon Airways canceled 140 domestic flights.

• The airlines did not publish a full route list when the cancellations were announced.

That spread shows how widely the storm was already affecting operations before its closest pass to the capital. Flights in and out of Tokyo were hit alongside regional services, adding pressure across the network rather than in just one part of the country.

The weather threat behind those cancellations is serious. Japan’s Meteorological Agency warned of torrential rain, wind gusts of up to 144 km/h, flash flooding, and landslides as the storm approached eastern Japan. Rainbands linked to Typhoon Dujuan had already been soaking Pacific-facing prefectures since 19 September, and some places in the Izu Islands and Chiba Prefecture had recorded more than 300 mm of rainfall.

The disruption wasn’t limited to the air. Heavy rain had already caused rail problems on 20 September, with some operators suspending services in Tokyo and neighboring prefectures. By the morning of 21 September, more than 4,000 households in Chiba Prefecture were also without electricity.

Local governments urged residents to stay indoors and prepare for possible evacuation in flood-prone areas. Forecasters said total rainfall through 22 September could exceed the region’s average rainfall for the whole month, with the risk that narrow bands of intense rain could develop over Kanto and central Japan and trigger sudden local downpours.

The storm has also disrupted major events beyond transport. The final day of the Tokyo Game Show, an outdoor music festival, and a professional baseball game in Chiba were all canceled. In Aichi Prefecture, organizers of the Asian Games postponed the equestrian competition from 21 to 22 September.

Because these cancellations were caused by severe weather outside the airlines’ control, financial compensation under EC 261 is unlikely for passengers on EU-bound or EU-departing flights operated by these Japanese carriers. Still, that doesn’t mean you’re without support if your journey was disrupted.

If your flight was canceled or heavily delayed, your airline should still provide care and assistance such as meals, refreshments, accommodation when needed, and the choice between rerouting and a refund where applicable.
