Naramata Dam

The Naramata Dam is a rock-fill dam in Minakami that rises 158 meters and spans 520 meters across a valley. The structure holds back water to create a large reservoir for the surrounding region.

Construction began in 1973 and the dam was completed in 1990, representing a major step in the region's water management development. The project was part of broader infrastructure efforts to control water resources across the prefecture.

Local restaurants in Minakami serve Dam Curry, where rice is molded to resemble the dam's shape, showing how the structure has become part of local food culture. This dish reflects the pride residents take in their region's engineering landmark.

The dam can be reached by taking the Joetsu Shinkansen to Jomo-Kogen station, then connecting to local transportation to the site. The area offers viewing points where you can walk along the dam and observe how water is managed for the region.

The dam serves a dual purpose as both a flood control structure and a hydroelectric power station, generating electricity while protecting the region. This combination makes it efficient in meeting different water management needs simultaneously.
