Katakura Dam

Katakura Dam is a gravity dam in Kimitsu that holds water for irrigation and regional water management. The structure creates a reservoir that supplies water to surrounding farmland and communities in the area.

The dam was completed in 1974 and became a key piece of water management infrastructure for the region. It has since supported agricultural needs and water distribution throughout the surrounding area.

The neighboring Kameiwa Cave contains a turtle-shaped stone formation, discovered in the early 2000s, which influenced its current name.

The best way to reach the dam is through Shimizu Keiryu Hiroba park, which has walking trails and connects to Lake Sasagawa. Wear sturdy shoes since pathways along the area can be uneven in places.

The dam system includes Nomizo Falls, where fireflies appear seasonally in early summer near the flowing water. This natural display makes the location a special spot for nature observers during warmer months.
