Typhoon Dujuan Threatens Japan With Torrential Rain and Violent Winds

Japan is bracing for Typhoon Dujuan as the powerful storm approaches the country’s eastern coast, threatening heavy rain, violent winds, flooding and dangerous waves.

Dujuan is expected to make its closest approach to eastern Japan on Monday, September 21, putting the Kanto region—including the Tokyo area—on alert during Japan’s Silver Week holiday.

The Japan Meteorological Agency says the storm is expected to pass close to the Kanto-Koshin region Monday afternoon and evening before accelerating northeastward.

A Dangerous Combination of Wind and Rain

The biggest threats will come from torrential rainfall, damaging winds, flooding and landslides.

Forecast rainfall could reach approximately 300 millimeters (12 inches) in parts of the Izu Islands, Tokai and Kanto during periods of the storm. Eastern Japan and the Tohoku Pacific coast are also expected to receive heavy rain.

The storm’s large size means dangerous weather can arrive well before the center of Dujuan reaches its closest point to Japan.

Strong winds could knock down utility poles, scatter debris and cause power outages. Coastal areas face dangerous surf and high waves, while heavy rain could cause rivers to rise and trigger landslides.

Timeline

Monday, September 21: Dujuan makes its closest approach to the Kanto region. The heaviest rain and strongest winds are expected during the afternoon and evening.

Monday night into Tuesday, September 22: The typhoon moves northeastward along Japan’s Pacific side, with heavy rain and strong winds continuing into Tohoku.

Wednesday, September 23: Dujuan is expected to move well east of Hokkaido and transition into an extratropical low.

Transportation could also be heavily affected. Train service, flights and other travel may face delays or cancellations as the storm moves through eastern Japan.

Officials are urging residents to monitor local warnings, avoid unnecessary travel during the worst conditions and stay away from flooded roads, swollen rivers and exposed coastal areas.

Dujuan’s exact impacts will depend on its final track, but Monday into Tuesday is the critical window for eastern Japan.
