Fuji school ［富士門流］ ( Fuji-monryū): A Buddhist school in Japan derived from Nikkō (1246–1333), one of the six senior priests appointed by Nichiren and his designated successor. In 1289 Nikkō left Kuon-ji temple, which Nichiren had founded at Minobu, and moved to a place at the foot of Mount Fuji. He did this because Nikō, another of the six senior priests, had influenced Hakiri Sanenaga, the steward of the Minobu area and a follower of Nichiren, to engage in actions and practices that deviated substantially from Nichiren’s teachings. Though Nikkō warned them repeatedly on this account, they disregarded him. After leaving Minobu, Nikkō settled in the Fuji district on the southwestern flank of Mount Fuji, where Nanjō Tokimitsu, one of Nichiren’s lay followers and a strong supporter of Nikkō, ruled as steward. Nikkō established a temple there named Taiseki-ji; this became the head temple of the Fuji school, which revered Nichiren and Nikkō as its founders. This school was the origin of what is today Nichiren Shōshū.
