Takataki Dam

Takataki Dam is a concrete gravity dam spanning the Yoro River in Chiba Prefecture, measuring 379 meters long and 24.5 meters high. The structure holds back water to create a reservoir that stretches behind it.

Planning began in 1974 following repeated flooding in the region, and construction finished in 1990. The project was designed to address water shortages and prevent future flood damage.

The Takataki Dam Memorial Hall presents exhibits about water management and displays the technical achievements of Japanese engineering in dam construction.

The dam supplies water to surrounding communities while managing flood risk in the region. Visitors can explore the area around the reservoir or fish when conditions permit.

During construction, engineers used innovative belt conveyor technology to efficiently place large quantities of concrete. This method was specially adapted for the structure's wide, low-profile design.
