Ishizuchi Mountain Tengu Legend

The Ishizuchi Mountain tengu legend concerns Hōkibō, a great tengu said to inhabit Ishizuchi Mountain (1,982 m), the highest peak in western Japan. Hōkibō is counted among Japan's Eight Great Tengu and stands as the emblematic tengu of Shikoku Shugendo. According to tradition, the mountain was opened as a sacred site by En no Gyōja in 701 (the fifth year of Emperor Monmu's reign). The core of practice involves ascending a cliff face known as the "chain place" (kusariba) using chains—a demanding ordeal that tests the commitment of ascetics. Hōkibō is said to oversee these trials and to bar those lacking sincere intent from approaching the summit.

The narrative unfolds in three movements: first, En no Gyōja's opening of Ishizuchi and the establishment of the ascetic practice-ground; second, Hōkibō's positioning as the mountain's master; and third, encounters between ascetics and pilgrims with Hōkibō. Shikoku Shugendo forms a distinct practice region linking Ishizuchi in Iyo, Yokokurayama in Tosa, and Kotohira in Sanuki, constituting a central pillar of Western Japanese mountain asceticism alongside the Ōmine and Katsuragi traditions of the Kinai region. The bond between the chain ordeal and tengu lore embodies the symbolic structure of Shugendo itself.

The primary sites of transmission are Ishizuchi Mountain, spanning Saijō and Kumakōgen in Ehime; the Ishizuchi Shrine's summit sanctuary and Jōjusha below it; and the main shrine at the foot (Nishi'nomiya Honsha, Saijō). The temples Senshōji and Yokominejī in the mountain valley form the core of Ishizuchi Shugendo practice and serve as outer pilgrimage sites within the Shikoku Eighty-Eight Sacred Places circuit. The founding narrative shares archetypal elements with En no Gyōja traditions at Ōmine in Nara Prefecture.
