Ootani Check dam

Ootani Check dam is a small water control structure in Fukuyama designed to slow down water flow in local drainage channels. It helps prevent soil erosion on slopes and reduces the speed of water movement during storms and heavy rain.

The dam was built as part of traditional water management practices that developed over time across the Hiroshima region. Such structures were created to address erosion and flooding problems common in Japan's mountainous areas.

The structure exemplifies Japanese engineering methods for controlling water flow while maintaining the natural balance of the surrounding environment.

The structure sits within a local drainage system that becomes active during rainfall. Visitors should be cautious in wet weather since water flow can increase significantly.

The structure uses traditional building methods and local materials specially adapted to the area's geological conditions. This approach allows it to function effectively for decades with minimal maintenance.
