Typhoon Dujuan Batters Japan’s Pacific Coast, Four Dead and Six Missing

Typhoon Dujuan brings torrential rain, flooding and landslides to Japan’s Pacific coast, leaving widespread damage across affected communities.

 Tokyo, September 22, 2026: Typhoon Dujuan has brought torrential rain, flooding and landslides to parts of eastern Japan, leaving at least four people dead and six others missing, according to the latest reports from Japanese authorities and public broadcaster NHK.

The storm affected areas around Tokyo and the wider Kanto region, with Kanagawa and Chiba among the areas facing serious disruption. Landslides triggered by intense rainfall damaged homes and blocked roads, while emergency teams continued search and rescue operations in affected communities.

Heavy Rain Triggers Flooding and Landslides

Dujuan produced exceptionally heavy rainfall across parts of eastern Japan. Oshima, south of central Tokyo, recorded 832 millimetres of rain over 48 hours, more than twice its usual September rainfall, according to NHK reports cited by multiple outlets. Tokyo’s Edogawa Ward also recorded 282.5 millimetres in 24 hours, a record for the area.

The intense downpours caused rivers to overflow and water to spread across residential areas. Landslides also buried or damaged houses in parts of Chiba and Kanagawa, prompting continued rescue operations.

Thousands of Homes Lose Power

The storm also disrupted electricity supplies across the region. More than 45,000 households in Chiba were without power as authorities dealt with the effects of the storm. More than 460 homes were reported damaged.

Transport services were also disrupted, with flights and railway operations affected as heavy rain and strong winds moved across eastern Japan. Earlier warnings had urged residents in vulnerable areas to remain alert for flooding, landslides and dangerous conditions.

Typhoon Moves Away From Japan

By Tuesday morning, Typhoon Dujuan had moved away from Japan and out over the Pacific, allowing authorities to lift or downgrade many of the heavy-rain and landslide warnings. However, saturated ground conditions mean that the risk of additional landslides can remain even after the main storm has moved away.

Emergency authorities continue to assess damage while rescue teams search for people reported missing. The full extent of the damage is expected to become clearer as crews reach areas affected by flooding and landslides.
