Typhoon Dujuan Triggers 275 Flight Cancellations Across Tokyo Airports

Typhoon Dujuan disrupted air travel across Tokyo on Monday, September 21, 2026, with major carriers canceling a combined 275 flights as the storm approached the Kanto region during Japan’s busy Silver Week holiday period.

What travelers in Tokyo are seeing at Haneda and Narita

Published coverage and airline advisories indicate the bulk of cancellations centered on Tokyo’s two main gateways: Haneda Airport (HND), which handles the city’s largest volume of domestic flights, and Narita International Airport (NRT), a major hub for long-haul international departures and arrivals. Flight information displays at Haneda showed widespread cancellations and rolling delays as schedules were adjusted around deteriorating conditions.

The 275-flight total reflects cancellations by Japan’s two largest airlines, with additional disruption expected from knock-on effects such as aircraft and crew being out of position. Even when an individual flight remains scheduled, day-of-travel reliability can change quickly as wind, rainfall bands, and runway operating limits shift hour by hour.

For travelers connecting through Tokyo, the practical impact often extends beyond the canceled segment. Missed onward connections, rebookings on later departures, and limited same-day seat availability can turn a short disruption into a multi-day travel change, particularly during a holiday week when loads are typically higher.

Airline cancellations: the numbers, and which flights are most affected

Reports indicate All Nippon Airways (ANA) and Japan Airlines (JAL) accounted for the 275 cancellations in the Tokyo area as Typhoon Dujuan drew closer to Kanto. Coverage of the day’s operations has described a heavy concentration in domestic routes, which are more frequent and more exposed to short-notice schedule adjustments.

Published coverage also indicates JAL canceled 120 domestic flights, and ANA canceled 140 flights, with some international cancellations also reported for JAL. While domestic flights typically dominate the cancellation count, international departures can be affected when widebody aircraft rotations, airport slot timing, and crew duty limits become difficult to manage under weather constraints.

Low-cost and regional operators also posted typhoon-related notices. Jetstar Japan, for example, posted travel alerts warning of potential impacts at Narita spanning September 21 into September 22, with some cancellations listed in its updates. These carriers can be especially sensitive to disruption because tight aircraft utilization leaves fewer spare planes to recover the schedule.

How rebooking and refunds are being handled right now

Airlines serving Tokyo have been steering customers toward self-service tools as call centers and airport counters face heavy demand. Japan Airlines posted an “Important Notice” for September 21 identifying Tokyo Haneda and Tokyo Narita as affected airports and advising passengers to keep checking flight status as additional decisions could be made later in the day.

JAL’s publicly posted guidance for weather disruptions indicates customers can generally change to another flight or request a refund when a cancellation or significant delay is decided, with online deadlines tied to the alternate flight departure and check-in timing. Travelers booked through third-party agencies are typically directed back to the original seller for changes, which can add time during high-volume disruption events.

U.S. and international carriers also issued waivers for Tokyo-area itineraries. Delta Air Lines published a typhoon advisory for Tokyo-Haneda that includes rebooking flexibility through a defined travel window later in the week, a common approach that allows customers to move trips without paying a fare difference when conditions disrupt normal operations.

Storm timing and why Tokyo’s holiday travel is vulnerable to disruption

Typhoon Dujuan approached Tokyo during Silver Week, a cluster of national holidays that can increase leisure travel demand and compress availability for last-minute alternatives. Coverage describing conditions on Monday pointed to heavy rainfall affecting parts of the Izu Islands and the wider Kanto region, a setup that can bring runway crosswinds, reduced visibility, and ground-handling interruptions even when an airport remains open.

In Tokyo, the transportation consequences are rarely limited to the airport perimeter. When strong winds or heavy rain affect regional rail lines and highway access, passengers can struggle to reach terminals on time, and airport staffing and baggage operations can slow. That combination can amplify delays and trigger additional cancellations beyond those announced early in the day.

For travelers watching the storm track, the most useful planning frame is often the airline’s operational window rather than the exact centerline forecast. Carriers may cancel proactively to avoid stranding aircraft and crews, then resume gradually as the storm passes and ramp operations can be conducted safely.

What to do if your Tokyo flight is canceled or still showing “on time”

For passengers scheduled to depart from or arrive into Haneda or Narita, the most actionable step is to monitor the operating carrier’s flight status and any published “special handling” or waiver notices, then make changes as soon as eligible. When cancellations mount, later flights can sell out quickly, and the best alternatives are often secured early in the disruption cycle.

Travelers whose flights are still operating should plan for airport access delays and longer processing times. Weather events can create chokepoints at check-in, security, and boarding, and last-minute gate changes are common as airlines reshuffle aircraft and consolidate loads across fewer departures.

If rebooking options are limited, consider adjusting the itinerary to depart a day later, switching between Tokyo’s airports when permitted by the carrier, or rerouting via another Japanese gateway if seats are available. For international itineraries, travelers may also want to confirm whether bags are checked through on revised routings and whether overnight accommodation is needed if new departures fall on the following day.
