Japan Lowers Izu Islands Mudslide Alert to Level 4 After Record Rain

Japan's Meteorological Agency downgraded the Level 5 mudslide special warning to a Level 4 mudslide danger warning for Oshima Town, Toshima Village, and Niijima Village in the Izu Islands. The change was announced on Monday, September 7, 2026. The downgrade comes as heavy rain conditions ease, but officials warn that the ground remains unstable due to record rainfall in the area. Residents are urged to maintain strict vigilance against potential mudslides despite the reduced alert level. The Izu Islands have experienced significant precipitation from a seasonal rain front, which continues to linger and poses ongoing risks. Local authorities are monitoring the situation closely as the region recovers from the severe weather event.
