Jinnichi (860-December 29, 916) was a priest of the Shingon sect from the early to late Heian Period. He was also called "Hakuun Joko."
Jinnichi received Kanjo (a consecration ceremony by pouring water onto the top of a monk's head) by Yakushin ENJOJI in Hakuun-ji Temple on Mt. Atago, Kyoto and learned Shingon Esoteric Buddhism from Gensho and Ensho. He served as Joko of Hakuun-ji Temple and in 916 was appointed as Risshi (Buddhist priest).
