Kizakai Ōmonoimi Shrine was once a hub for practitioners of the ascetic religion Shugendō in the Yashima area, the center of mountain worship on Mt. Chokai.

Various rituals and practices were held here throughout the year, such as entering of the mountain in the spring and autumn, and a ritual called the “insect repelling festival.” Of these rituals, the “insect repelling festival” is still held today, and is designated as an Intangible Folk Cultural Property of Akita Prefecture.
