A shrine built to worship the place where Sukuhikona no Mikoto (a god in Japanese mythology) who appears in the Kojiki and Nihon Shoki is said to have died. The temple was completed in 1932, and Sangoden was completed two years later.
Sango-den is built on the north slope along the approach, with about 90% of the floor area protruding into the mountain cliff, and the longest leg is 8.3 meters. In addition to the traditional pierced construction method, modern techniques are also actively incorporated into the construction. Additionally, the upper one-story section has glass doors on three sides, creating an open interior space.
