Komaki Dam, Gravity dam in Tonami, Japan.
The Komaki Dam rises 79.2 meters above the Shō River, featuring 17 tainter gates for spillway control and Francis-type turbines generating 90.2 megawatts of power.
Completed in 1930 after five years of construction, this engineering achievement marked a milestone as the largest arch-gravity dam in East Asia at that time.
The dam operates boat services through Shogawa Gorge, where passengers hear traditional Gokayama folk songs while viewing the surrounding mountains and waters.
Visitors reach the dam via a 70-minute Kaetsuno bus ride from Shin-Takaoka Station, with the last portion requiring a brief walk to the entrance.
The structure maintains two separate water routes: one leading to Omaki Spa, accessible only by boat, and another offering views along the Nagasaki Bridge course.
