Typhoon Dujuan is bearing down on Tokyo, and the disruption is already substantial. At least 275 flights have been cancelled across Japan, with Japan Airlines alone scrapping 120 domestic and 15 international services and All Nippon Airways pulling another 140 domestic flights. Rail operators in Tokyo and nearby prefectures have suspended services on several routes, and more than 4,000 households in Chiba, just east of the capital, were without power on Monday.
The Japan Meteorological Agency has flagged an alarming forecast: rainfall accumulating through Tuesday could exceed what the region normally receives across the whole of September — potentially record-breaking totals. Authorities are warning of flooding and landslides and urging residents and visitors to stay alert as conditions deteriorate.
The storm is no lightweight. At the last reported position, Dujuan was generating winds of about 144km/h and sat roughly 110km from Hachijojima, one of Tokyo's outlying islands.
The knock-on effects reach well beyond airports and train stations. Tokyo Game Show — one of the biggest video game trade fairs in the world, which had opened the previous Thursday — shut its doors early, cancelling its final day entirely. A major outdoor music festival and a baseball fixture in Chiba were also called off as the region braced for the worst.
If you're in Japan right now, the key advice is to expect fast-changing conditions. Transport schedules can shift with little notice, so check airline and rail operator updates before heading to stations or airports, keep an eye on JMA warnings, and build slack into any onward travel plans. Anyone with a flight booked in or out of Tokyo in the next day or two should contact their airline proactively — many carriers offer fee-free rebooking during major weather events — and consider travel insurance cover for weather-related delays if you haven't already.
Japan sits squarely in typhoon season between roughly May and October, with August and September the peak months, so this is a good reminder for anyone planning a trip in that window: keep itineraries flexible, sign up for weather alerts, and know what your airline and hotel policies cover before a storm arrives.
