Chiba heavy rain causes 10 deaths and massive logistics disruption

Chiba heavy rain urban flooding abandoned vehicles logistics disruption energy storage damage

The heavy rainfall in Chiba Prefecture, referred to as the ‘Reiwa 8 August Chiba Heavy Rain,’ has caused significant casualties and infrastructure damage. Authorities report 10 deaths and 2 people missing following the extreme weather event, which saw Chiba City's Chuo Ward record a 24-hour rainfall of 367 mm—the highest since statistical records began 76 years ago.

Logistics and transportation have been severely impacted. Major delivery services, including Japan Post, Yamato Transport, and Sagawa Express, have reported delays or suspended operations at various locations due to flooding. In Chiba City, approximately 2,500 vehicles were left abandoned due to flooding, creating hazards for traffic and complicating recovery efforts for towing services.

Infrastructure damage extends to the energy sector. Grid Synapse Co., Ltd. has initiated free damage assessment support for high-voltage energy storage facilities in the region to check for flooding and operational integrity. While many major road closures have been resolved, some local prefectural roads remain blocked due to landslides and road damage.
