According to the temple records, it was built in 642 to enshrine the Buddha statue presented by King Seong (reigned 523–554) of Baekje. Later, with the patronage of Minamoto no Yorimoto and the Hojo clan, the temple expanded to become a full monastic compound. Both Master Shinran and Master Ippen visited and worshipped at this temple. The temple became popular as a major temple for the worship of Amitabha Buddha in Nagasaki. The temple was damaged and repaired many times before assuming its present appearance. The temple belongs to both the Tendai and Pure Land schools of Japanese Buddhism.
