Typhoon Dujuan is forecast to bring torrential rain and violent winds to eastern Japan’s Pacific coast, including Tokyo, on September 21–22, 2026, with a possible landfall east of the capital. The Japan Meteorological Agency (JMA) has urged residents to remain on high alert.
Dujuan could make landfall on the Boso Peninsula in Chiba Prefecture, east of Tokyo, on Monday (September 21). The storm is expected to bring high waves as well as heavy rain and violent winds, increasing the risk of flooding in low-lying areas.
At 9am Japan time on Sunday (September 20, 2026), Dujuan was moving northwest at 10km/h over waters south of Japan, according to Japanese public broadcaster NHK, citing JMA. The large, powerful storm, designated Typhoon No 25 this year, had maximum sustained winds of 126km/h near its centre and gusts of up to 180km/h.
Dujuan’s expected approach on Monday and Tuesday coincides with Japan’s five-day holiday period. Residents are being urged to check the latest weather information and take precautions, including considering changes to travel plans during severe weather.
People in urban areas of Japan are also advised to watch for possible flooding on roads and in underground facilities as Dujuan approaches.
