Japan: Torrential Rains in Chiba Leave 13 Dead and Thousands of Damages

Wednesday 19 August 2026 - 08:15

The toll from the torrential rains that hit Chiba Prefecture, east of Tokyo, continues to rise. Local authorities reported on Tuesday that 13 people have died, while one person remains missing following the exceptional rainfall recorded last week.

The meteorological phenomenon also caused significant material damage. More than 2,300 homes were affected, with flooding impacting both the lower levels and the upper floors of buildings.

Roads Still Congested with Vehicles

The consequences of the severe weather are particularly visible on the road network. Approximately 2,700 vehicles swept away or stranded by the waters remain abandoned on several routes.

This situation complicates clearance operations and severely disrupts traffic. The blocked vehicles have caused significant slowdowns and traffic jams in several areas of the prefecture.

Authorities continue their cleanup and damage assessment operations, while some areas remain affected by the aftermath of the flooding.

Exceptional Rainfall Occurred Within Hours

The most intense precipitation was recorded between last Thursday and Friday. Its magnitude prompted the Japan Meteorological Agency (JMA) to issue its highest alert level in certain areas.

Level 5, corresponding to the highest degree of the Japanese meteorological alert system, indicates a particularly significant risk to the population, especially due to heavy rains and landslides.

The rapid succession of rain episodes has thus favored flooding and increased the risk of landslides in several sectors.

Search Operations Continue

As the human toll now stands at 13 dead, authorities continue to search for one missing person. Operations remain mobilized to try to find any potential victims and secure the most affected areas.

The extent of the material damage also reflects the severity of the meteorological episode. With over 2,300 homes damaged and thousands of vehicles stranded, restoring the infrastructure could take several days, or even longer depending on the areas.

This episode once again highlights the vulnerability of certain regions in Japan to intense rainfall and the associated risks of flooding and landslides.
