Typhoon Dujuan triggered 275 flight cancellations across Japan Airlines and ANA on Monday, disrupting operations at Tokyo Haneda and other airports as severe weather moved towards eastern Japan. Japan Airlines cut 135 services and ANA 140, with the disruption hitting domestic schedules hardest and affecting some international flights. The cancellations came as the storm brought strong winds, heavy rain and warnings of further transport disruption across the Kanto region.
The bulk of the impact fell on Haneda, the country’s busiest domestic hub, while Narita and Hachijojima also saw disruption. Several reports placed the number of affected passengers at about 42,600. The Japan Meteorological Agency warned that rainfall could exceed September’s monthly average in some areas, raising the risk of landslides and local flooding.
The storm also fed into wider transport and infrastructure problems, including rail suspensions and power cuts in Chiba prefecture, where more than 4,000 homes were reported without electricity. The cancellations illustrate how quickly severe weather can remove significant capacity from Japan’s domestic network during peak travel periods and force carriers to reshuffle operations at short notice.
