However, since the shrine originally was located in precincts of Horaku-ji Temple (Shingonshu sect, founded by Prince Shotoku) in the same town as a chinju-sha shrine (Shinto shrine on Buddhist temple grounds dedicated to the tutelary deity of the area), then was transferred to the current place by the Ordinance Distinguishing Shinto and Buddhism in early Meiji period to take over ujigami (a guardian god or spirit of a particular place in the Shinto religion) of Kuroda village (confirmed by a pair of stone lantern with the inscription of the transferred year as '1770'), the present location of Ioto-jinja Shrine technically is not the palace site.
ただし、もともとは鎮守社として同町の法楽寺（真言宗、聖徳太子開基）の境内にあったものが、明治時代初期の神仏分離令により現社地へ遷座し黒田村の氏神として引き継がれたという経緯（旧地より移した「明和7年(西暦1770年)」の紀年銘をもつ石燈籠１対により確認できる）の為、現在の庵戸神社は厳密には宮跡とはいえない。
