The shrine’s home page (Japanese) traces its roots back to a temple founded in the Muromachi Period. A document called the Hanyain Bunsho, which has been designated as a tangible cultural asset by Fujimi-shi, notes the foundation of a temple, Shūgen-dera, as a sub-temple of the Kyōto-based Shōgo-in. As a result of the government-enforced separation of shrines and temples (shin-butsu bunri) in the early Meiji Period a new religious institution, the Mizumiya Shinden, where Amaterasu Ōkami and four other gods were worshipped was set up. Over a century later, in 1993, this was renamed Mizumiya Jinja.
