Japan's weather agency and local authorities warned on September 21 that Typhoon Dujuan was approaching the Kanto region's Pacific coast, bringing risks of torrential rain, flooding, swollen rivers, violent winds and landslides. A Level 5 landslide emergency warning was issued for Oshima, while some municipalities in Tokyo and Kanagawa issued Level 4 evacuation orders.

Why it matters

This is a developing life-safety event. People in affected areas should follow the latest Japan Meteorological Agency and municipal alerts, comply with evacuation orders, and stay away from rivers, slopes and flooded roads. Transport and flights may be disrupted; the overall toll and damage remain unconfirmed.

Full report

The Japan Meteorological Agency warned on September 21 that powerful Typhoon Dujuan was approaching Kanto along Japan's Pacific coast. Intense rain could rapidly cause surface flooding, swollen rivers and landslides. Reuters reported that rainfall exceeded 300 millimetres in some locations and that a top-level landslide emergency warning was issued for Oshima.

Tokyo's Minato City updated its notice at 2:15 p.m. local time on September 21, issuing Level 4 evacuation orders for designated landslide-risk zones. Authorities in Yokosuka and Kawasaki in Kanagawa also announced typhoon-related evacuation measures or opened shelters. Alerts can change quickly as rain bands and river levels shift, so readers should use JMA and municipal live updates.

Weathernews said in an update at 6:24 p.m. that the typhoon was then closest to Kanto, with heavy rain in Chiba and Ibaraki expected to continue into the evening. The Izu Islands and Kanto coast remained at risk from landslides, low-lying flooding, swollen rivers, strong winds and high waves. People should avoid rivers, coasts, slopes and water-covered roads unless travel is essential.

A social-media video included in the email lead claimed that a vehicle was fully submerged around Chiba and Narita. N Globe could not verify that the video was recorded there on September 21. Public searches also found widely circulated submerged-vehicle footage from deadly flooding in Chiba and Narita on August 14, so this report does not use the video as evidence or repeat its casualty and damage claims.

The typhoon track, official weather warnings and some evacuation orders are confirmed. As of publication, N Globe had not verified a complete casualty or damage toll from this episode in Kanto.
