Overview
- Typhoon 8 accelerated along the Bōsō Peninsula and became an extratropical low offshore Fukushima on Saturday morning, the Japan Meteorological Agency said.
- Typhoon 7 tracked northeast‑east off the Tokai coast and was moving toward the Kanto region, with the JMA forecasting it would become extratropical over eastern waters in the early hours of June 28.
- Prefectural and municipal governments issued level‑4 landslide danger warnings for places such as Tateyama in Chiba, Miura in Kanagawa and Shimoda in Shizuoka, a signal that evacuations or immediate protective action may be needed.
- Weather stations recorded severe local conditions, including maximum gusts near 29 m/s at Izu Oshima and Katsuura and a 12‑hour rainfall total of 163.0 mm at Kimitsu/Sakahata, the highest June measurement at that site.
- Rail operators suspended multiple JR East lines including sections of the Sobu, Uchibo and Sotobo routes and cancelled dozens of services, and the JMA warned that small, fast‑changing storms can force rapid forecast revisions.
