Yomikaki Dam

Yomikaki Dam is a concrete gravity structure built across the Kiso River in Okuwa that manages water flow through its substantial mass. The design relies on the weight of the structure itself to hold back water and regulate its passage downstream.

The structure was completed in 1960 by Hazama Corporation as part of Japan's post-war reconstruction efforts. This infrastructure was built during a period when the country prioritized developing water management and power generation capabilities.

The surrounding walking paths near the dam structure allow residents to observe seasonal changes in water levels while learning about regional hydrology.

Walking paths around the structure offer vantage points to observe water levels and the surrounding landscape. Access is typically straightforward, allowing visitors to explore the area on foot.

The dam's position at coordinates 35.658889°N and 137.620278°E creates a water regulation point that supports multiple downstream communities.
