It forms part of Seppiko-Mineyama Prefectural Natural Park.

Mount Seppiko is a place for the ascetic practices of Shugendō in this region.

Mount Seppiko also is considered to be developed for Shugensha, practitioners of Shugendō.

Kaya Jinja was originally a typical example of Shinbutsu shūgō, literally "fusion of practices from both Shinto and Buddhism", and had a Buddhist temple, Seppiko-san Kongo Chingo-ji, just beside the Shinto shrine.

Mount Seppiko is one of the mountains which still have some areas which women are prohibited from entering, in order not to disturb the training of Shugensha.
