Although there are many theories in regard to the exact year of making and where they were first enshrined, it is generally believed that the nine dry-lacquer statues and Shukongoshin-zo statue have been enshrined from the beginning and the other four earthen statues are Kyaku-butsu (which were moved from other Hall later on).
細い制作年代や当初の安置状況については諸説あるが、9体の乾漆像と執金剛神像が当初からの安置仏で、残りの塑像4体は客仏（後世に他の堂から移された像）とするのが通説である。
