The original temple was built in 1234 by Hōnen’s disciple, Genchi (1183-1238) in memory of his master and was named Chion-in. While the temple was affiliated more closely in the early years with the Seizan branch of Jodo Shu, its 8th head priest, Nyoichi (1262 – 1321) was deeply influenced by the priest Ryōkū, a disciple of Ryōchū who was the 3rd head of the Chinzei branch of Jodo Shu Buddhism, and disciple of Bencho. Later Nyoichi’s successor Shunjō (1255-1355) advanced this further by citing a biography where Genchi’s disciple Renjaku-bo and Ryōchū agree that there existed no doctrinal differences between them.Wikipedia
