Overview
- Japan’s Meteorological Agency said Saturday that Typhoon No.25 was west of Chichijima, moving about 25 km/h with a central pressure of 975 hPa, sustained winds near 30 m/s and gusts up to 45 m/s.
- Forecasters expect the storm to turn north and intensify while approaching the Izu Islands and the Pacific coast of eastern Japan on Sept. 20–21 and it could reach or make landfall near the Bōsō Peninsula around Sept. 21.
- The agency warned of violent winds, high waves and warning‑level heavy rain that could trigger landslides, low‑land inundation and river flooding across Kantō, Tōkai, Kinki and Pacific coastal areas of eastern Japan.
- The timing during the long holiday raises the chance of major travel and service disruption, and authorities urged residents to prepare emergency supplies, secure property and follow local evacuation orders.
- Forecasts show heavy rainfall totals that could reach about 300 mm in parts of Kantō and Tōkai on Sept. 21, but the storm’s exact track and intensity can change so residents should monitor official updates closely.
