Ichihara Floods: Streets Become Rivers in Chiba Deluge
21 Aug
Summary
- Floodwaters inundated Ichihara, Chiba, during August 13-14 rainfall.
- Security footage captured rising waters engulfing residential streets.
- Residents experienced multiple inundations due to a failed drainage system.
During August 13 and 14, torrential rainfall inundated residential streets in Ichihara, Chiba Prefecture. Security camera footage from the Chiharadai district showed floodwaters rising rapidly, turning roads into impassable rivers. Early evening on August 13 saw visible crosswalks, but by around 7 p.m., the water level had risen significantly, immobilizing vehicles.
Although the rain briefly weakened after 8 p.m., allowing visibility and pedestrian movement, intense downpours returned from 9 p.m. The water surged higher, covering vehicle license plates and creating swift, muddy currents. One resident described their home flooding 45 centimeters, experiencing the water receding only to return with renewed force.
Preliminary figures indicated an intense 93.5 millimeters of rain fell in the hour up to 8 p.m. in the affected district. City officials attributed the flooding to the prolonged downpour exceeding the capacity of the local drainage system, leading to accumulation in low-lying areas. This event followed similar damage from heavy rain in October 2019, for which municipal work had been done to improve stormwater drains.
