The Enma-o, Shimyo, Shiroku, Kushijin and Ankoku Doji statues, which are enshrined in Enma-do, were formerly owned by Nishi-Kannon-ji Temple on the western base of Mt. Tenno in Shimamoto-cho, Osaka Prefecture but were transferred to Hoshaku-ji Temple after this temple closed during the anti-Buddhist movement at the beginning of the Meiji period.
閻魔堂安置の閻魔王、司命、司録、倶生神、闇黒童子の各像は、天王山西麓の大阪府島本町にあった西観音寺旧蔵で、同寺が明治の廃仏毀釈で廃寺になったため宝積寺に移された。
