It is difficult to identify the image of the wall No. 8 by the iconographic characteristic, however, it is estimated as Monju Bosatsu (an attendant figure of the left of Shaka Nyorai) since the image on the wall No. 11, which is paired with the image on the wall No. 8, is Fugen Bosatsu (an attendant figure of the right of Shaka Nyorai).
図像的特色からは尊名の確定が困難であるが、この絵と対をなす11号壁が普賢菩薩（釈迦如来の右脇侍）像であることから、8号壁の像は文殊菩薩（釈迦如来の左脇侍）像であると判断される。
