Muramatsu-san Kokuzo-do is a temple established by Priest Kukai in 807. Since then it had been under the protection of the successive domain lords of Satake clan for 500 years. In the Edo period, Tokugawa Ieyasu dedicated the land that produced 50 koku of rice to the temple. It was flourished under the protection of Tokugawa Mitsukuni. In back of the main hall is Muramatsu Daijingu Shrine, to which the deity of Ise Shrine was imparted during the reign of Emperor Kanmu (737-806). The shrine is famous for the custom of “Jusan Mairi,” in which 13-year-old boys and girls visit the shrine to pray for their future success of life. Kokuzo-do now belongs to Buzan School of Shingon Sect. Its main object of worship, the image of Kokuzo Bosatsu (Buddhist deity of wisdom and memory) is counted as one of 3 Finest Images of Kokuzo Bosatsu in Japan together with Asama Kokuzo-son in Ise and Yanaizu Kokuzo-son in Aizu. At the present time it is visited by a lot of people seeking for escaping evil spirits and success of life.
