Mount Fuji

is one of the tallest peak in Japan and lies 100 kilometres (62 mi) southwest of Tokyo. It is also one of the holiest sites in the country, as its own natural powers of purification were enough for the miko Tsukiyomi to seal the Kon blade of the Naginata of Kenkon. Only the spiritual power of Mount Hakurei came close to it, but when Mt. Hakurei was destroyed in a violent cataclysm caused by Naraku, Mount Fuji's legend and power was unrivaled. Mount Fuji was also the site where Akitoki Hōjō destroyed the Celestial Robe, throwing the garment into the mountain's crater so that its power could never be used for evil again, as it had been by the Princess Kaguya.

Trivia

 * Both times Mount Fuji appears in the series, it accompanies an appearance by Akitoki Hōjō. Akitoki and his family's connection to Mount Fuji and powerful objects linked to it makes historical sense given that Mount Fuji lies in what was once which was at one time controlled by the Hōjō clan; although by the time of the series, it had fallen into the hands of the ; the Hōjō clan's possession of these objects must therefore predate the series by at least several hundreds of years. Curiously, however, in the real world, the two Hōjō clans (both the family that once controlled the territory surrounding Mt. Fuji and Akitoki's family) were not related by blood, even though they shared the same name, crest, and even the same home province (Sagami Province, which lies between Suruga and Musashi Province).
