Japan Issues Highest Emergency Warning for Oshima Town Amid Typhoon Champi Rainfall

The Japan Meteorological Agency (JMA) has issued a Level 5 emergency warning, its highest alert, for Oshima Town in the Izu Islands. This follows 387.5mm of rain in 24 hours, which caused a landslide in Yokosuka, Kanagawa. The extreme rainfall is linked to Typhoon Champi, which is intensifying more rapidly than anticipated in the Mariana Islands and is projected to deepen further, posing continued severe risks.
