The shrine stands on part of the former grounds of the Shikinaisha Nyashiro-ni-masu-Amateru-mitama-jinja, where it was long served as a subordinate shrine. In March 1669 (Kanbun 9) that shrine moved to the northwest corner and the two were separated. A new worship hall was built in 1979 (Showa 54).

The shrine is popularly called Ibo-mizu Jinja because it is believed to cure warts, and its grounds hold a spring known as Ibo-mizu, recorded in the Settsu-shō as "Tama no Ii" and in the Settsu Meisho Zue as "Yorube no Mizu", credited with healing various illnesses. Within the precinct stand Sumiyoshi Jinja and Sakura-hime Inari Jinja.
