Tsuyoshi SHIGA, a researcher of shrines listed in the Engishiki Jinmyocho (register of shrines and deities in the book of regulations of the Engi era), believes Shimo Goryo-jinja Shrine to be Izumoinoheno-jinja Shrine (classified as a Taisha) listed in the Engishiki Jinmyocho but its history is unclear and there is no mention of Izumoinoheno-jinja Shrine in the history records held at Shimo Goryo-jinja Shrine.
