Typhoon approaches eastern Japan, prompting flood and landslide warnings

A powerful typhoon was approaching Japan’s Pacific coast on ​Monday (September 21, 2026), bringing torrential rain, violent winds and ‌a heightened risk of landslides across the ​Kanto region and other ⁠parts of eastern Japan, the weather agency said.

The Japan Meteorological Agency (JMA) warned that conditions could ‌deteriorate rapidly as Typhoon Dujuan was forecast to pass close to ‌the Tokyo metropolitan area later ‌in ⁠the day.

Heavy rain has already ⁠drenched parts of the Izu Islands, Chiba Prefecture and other Pacific coastal areas, with some locations ​recording more than ‌300 mm (12 inches) of rainfall since Saturday (September 19, 2026).

The JMA said downpours could intensify from Monday afternoon as the typhoon nears ‌the Kanto region, an area ​that includes Tokyo and surrounding prefectures.

At the Asian Games in central ⁠Japan’s Aichi Prefecture, organisers postponed the equestrian eventing competition until Tuesday (September 22, 2026) due to ‌the approaching typhoon.
