Typhoon Chan-hom is moving northwest toward Japan's Pacific coast and is expected to make landfall on Tuesday, Aug. 11 [1, 3].
The storm threatens to disrupt critical transportation networks and air travel in the Kanto region, including the Tokyo metropolitan area, during a peak summer period.
Designated as the 15th storm of the 2026 Pacific typhoon season [1], the system is being driven toward the mainland by prevailing atmospheric conditions, the Japan Meteorological Agency said [4, 1]. On Monday at 9 a.m., the storm was moving at a speed of 15 kph [2].
Forecasters expect the system to impact the Pacific coast, specifically within the Ibaraki and Fukushima prefectures [1]. However, other reports indicate the storm may make landfall closer to the broader Kanto region [5].
The timing of the landfall remains subject to slight variation. Some reports indicate the storm will arrive Tuesday afternoon [6], while other data suggests it may make landfall overnight [7].
Japanese airlines have already begun halting flights as the system nears Tokyo [7]. Local authorities said the storm will likely affect transportation systems throughout the Kanto region as it moves inland [5].
Residents in the projected path are monitoring updates from the Japan Meteorological Agency as the storm continues its northwest trajectory toward the main island [4, 1].
“The storm threatens to disrupt critical transportation networks and air travel in the Kanto region.”
The approach of Typhoon Chan-hom highlights the vulnerability of Japan's high-density transport hubs in the Kanto region. Because Tokyo serves as the nation's primary economic and transit artery, even a moderate tropical system can trigger cascading delays across national logistics and international travel schedules.
