The shrine legend tells that Toyouke no Okami was originally enshrined at Manaihara (now the site of the external sessha (auxiliary shrine (dedicated to a deity close-related to that of a main shrine)) Okumiya Manai-jinja Shrine) and the shrine was named Yosano Miya.
社伝によれば、元々真名井原の地（現在の境外摂社・奥宮真名井神社）に豊受大神が鎮座し、匏宮（よさのみや、与佐宮とも）と称されていた。
