Typhoon Chan-hom Hits Japan Right as Obon Travel Peaks

Japan's busiest domestic travel week of the year is starting under a cloud, literally. Typhoon Chan-hom, tracked by Japan's Meteorological Agency as Typhoon No. 15, made landfall in southern Ibaraki Prefecture around 8 p.m. on August 11 with sustained winds near 25 meters per second. According to the Japan Meteorological Agency, it was the first typhoon on record to make landfall in Ibaraki since tracking began in 1951, a notable milestone driven by the storm's unusual east-to-west path around a high-pressure system parked north of the archipelago. The timing could not be more inconvenient for travelers. Obon, Japan's largest domestic travel holiday, runs August 13 to 16 this year, and with Mountain Day on August 11 attached to the front of it, many workers get six straight days off starting the 11th. That means the country's trains, flights, and highways were already bracing for their heaviest crowds of the year just as the storm came ashore. The immediate damage was contained but real. All Nippon Airways canceled 58 flights serving Haneda and Narita on August 11, and Japan Airlines canceled several more, together affecting well over 800 passengers. JR East suspended sections of the Joban Line, which runs north from Ibaraki through Fukushima toward Miyagi, while the Tokaido Shinkansen between Tokyo and points west avoided a large-scale shutdown. By the morning of August 12, operations at the major Tokyo airports and on the core Shinkansen network were reported back to close to normal, though regional lines in the Tohoku and Joban corridors were still working through delays. The bigger risk for anyone booking a Japan trip right now is not Chan-hom itself, which is expected to weaken to a tropical depression by Wednesday afternoon, but the fact that it hit during the exact week when Japan's rail and air networks have zero slack. Obon reserved Shinkansen seats routinely sell out weeks ahead, and railways add a peak-period surcharge on top of normal reserved-seat fees, roughly 200 yen extra on August 13 and 14, and 400 yen extra on the 15th and 16th. When a storm forces cancellations into a week that is already sold out, rebooking options shrink fast and standing-room-only travel on unreserved cars becomes common. What should travelers actually do. If you already hold Shinkansen reservations or domestic flights for August 12 through 16, check your carrier's app or website directly rather than relying on headlines, since JR East and the airlines update service status by line and route as conditions change through the day. Travelers connecting through Narita or Haneda in the next 48 hours should build in extra buffer time before any onward international connection, since a backlog from Tuesday's cancellations can ripple into subsequent departures even after weather clears. If you are still deciding when to fly into Japan for a trip touching this week, shifting arrival to August 17 or later avoids both the tail of any storm-related disruption and the worst of the Obon return rush, when trains heading back into Tokyo see their own crowding spike. Mid-August is peak typhoon season in Japan, and this is unlikely to be the last storm to test the network before autumn. Japan's Meteorological Agency had already flagged a second system approaching Okinawa in the same week, a reminder that anyone with Japan travel booked through September should keep travel insurance with storm coverage in place and register for airline text or app alerts rather than checking only once before departure. For international visitors, the practical lesson from Chan-hom is less about this single storm and more about the calendar: booking around Obon in mid-August means accepting that both crowding and weather risk are at their yearly peak, so build flexibility into any itinerary that touches this window.
