Tateyama Okami refers to the deities enshrined at Mount Tateyama in present-day Toyama Prefecture, one of Japan's three sacred mountains along with Mount Fuji and Mount Haku. The mountain has long been venerated as a dwelling place of kami associated with its dramatic alpine terrain, snow, and volcanic features, and it became a major center of Shugendo mountain asceticism blending Shinto and Buddhist practice. Tateyama Okami is honored primarily as a guardian spirit of this sacred peak and the natural forces embodied within it, rather than for any specific promised benefit.
