The Miroku image was engraved on a rock measuring approximately 16 m in height and 15 m across but has been completely lost with the exception of the halo cavity so that the original grandeur of the image can now only be inferred from images within 'Kakuzensho' (a collection of iconographical drawings by the Shingon)' and the painting 'Kasagi Mandala-zu' Painting (Important Cultural Property) at the Museum Yamatobunkakan.
弥勒磨崖仏は高さ約16メートル、幅約15メートルの岩に刻まれたが、現状では光背の窪みが確認できる程度で像の姿は全く失われており、往時の像容は「覚禅鈔」（図像集）所収の図像や、大和文華館所蔵の「笠置曼荼羅図」（重要文化財）からしのぶほかない。
