Arimine Lake is an artificial lake created by the construction of the Arimine Dam. The dam took five years to build. Efforts were taken to ensure that the natural surroundings were protected and the Arimine Forest Cultural Village was established. As a result, the area has remained unspoilt and has been designated as the Toyama Natural Park, National Rest Home and one of Japan's top 100 forests and water sources.

The fresh green and red leaves of the beech, oak and maple trees are wonderful. A sight of particular beauty is that of red leaves in autumn with the snow-covered Mt. Yakushi in the background. Wadagawa Valley, which lies between Komi and the dam, is so beautiful it will take your breath away. And it's not just the scenery that's so attractive, but the natural treasury of precious plants and wild birds.　

The camping area at the shoreside is popular for people who like the outdoors.
