Typhoon No. 15 Hits Japan: Heavy Rain and Landslide Risks Persist
Typhoon No. 15 made landfall in Japan on September 4, 2025, bringing heavy rain and strong winds to western and eastern regions. According to the RSMC Tokyo – Typhoon Center, the storm formed from a tropical depression southeast of Minami Daitō Island on September 3 and strengthened into a typhoon. It initially moved north, then shifted northeast, skirting Miyazaki Prefecture’s coast before hitting land near Sukumo City in Kōchi Prefecture around 4 PM local time.
The typhoon is forecast to bring heavy rain across wide areas of western and eastern Japan through September 5, raising concerns over landslides, flooding, and river overflows. The combination of warm, moist air from the typhoon and a high-pressure system, along with a front crossing Honshu, is expected to intensify rainfall. Authorities warn that even after the worst of the rain passes overnight, saturated soils in Pacific-facing regions remain at high risk of landslides.
Residents and travelers in affected areas are advised to stay alert and follow official warnings from national meteorological services. The RSMC Tokyo – Typhoon Center provides valuable tracking information, but it is crucial to heed local advisories for safety. As the storm moves northeast, its impact may extend, so continued vigilance is essential.
