The temple was built in his own residence by the vassal Sukuya Mitsunori [Yadoya Mitsunori] of the Five-year-old Shōgon Hōjō Tokiyori [Tokigyo], with his brother Nichirō of Nichiren as an opening mountain. Gwangju's father Gyōki was the person who handed over Nichiren's "Rissho-an-kokuen" to Tōyori, who later attributed himself to Nichiren-Nichirō. In front of the main temple stands a stone monument, about 3m high, which is a photograph of Nichiren's autograph. On the right side of Yamanaka, there is a dungeon that imprisoned Nichiren when he was exiled to Sado. The precincts are planted with four seasons of flowering trees such as plums and camellias, giving a gorgeous atmosphere. It is famous for the giant tree of a 200-year-old kaido, which is about 5m high, 1.2m rooting around and produces light-red flowers in early April. About 300 species of hydrangeas can be seen from early May to early June.
