Arimine Dam

Arimine Dam is a gravity dam in Toyama Prefecture that spans across the Wada River. The structure reaches 140 meters high and features two distinct bends in its middle section.

Construction of the dam began in 1956 by Hokuriku Electric Power Company following earlier efforts that were interrupted during World War II. The project represented major postwar infrastructure development for the region.

The dam creation led to the formation of Arimine Lake, which has become part of the regional identity and recreational activities in Toyama Prefecture.

The site is most accessible during dry days as rain can make roads around the dam area slippery. Visitors should wear sturdy shoes and use marked paths to get the best views of the structure and the reservoir.

The reservoir behind the structure holds a large volume of water and serves multiple purposes including irrigation, flood control, and water supply for industry and communities. This multifunctional role makes it more than just a power-generating facility for the surrounding region.
