Shijūku-in ［四十九院］: A temple of the Tendai school in Kambara of Suruga Province, Japan, where Nikkō, Nichiren’s eventual successor, entered the priesthood and spent his childhood. After Nichiren went to live at Mount Minobu in 1274, Nikkō used the temple as a center for his propagation activities in the Fuji area. Gon’yo, the temple’s administrator, became antagonistic toward Nikkō and other followers of Nichiren including Nichiji, Shōken, and Kenshū, and expelled them from the temple, claiming that their teachings were false. Nikkō sent a joint petition to the Kamakura shogunate condemning the expulsion as unreasonable and requesting an official religious debate with Gon’yo.
