Typhoon Dujuan battered Tokyo and eastern Japan, causing record rainfall, strong winds and landslides, including 832 mm of rain in 48 hours on Izu Oshima Island, Tokyo, Japan.
Izu Oshima is a volcanic island in the Izu Islands of Tokyo, Japan, in the Pacific Ocean.
Dujuan formed over the North western Pacific Ocean and became Japan’s 25th named storm of the season.
Warm ocean waters and rising moist air helped strengthen the tropical cyclone, while the Coriolis effect caused its rotation.
Interaction with Japan’s autumn rain front (Akisame zensen) intensified rainfall, flooding and landslides.
