From the transformation bodies (J. kebutsu) of Amida Nyorai (Skt. Amitābha) in the crown of each of these bodhisattvas, both can be identified as Kannon (Skt. Avalokiteśvara). Two bodhisattva figures likewise realized through the repoussé technique resembling these ones appear as part of an Amida triad; they are the attendant bodhisattvas that flank Amida Nyorai (Skt. Amitābha) in a work found among the collection of Hōryūji Treasures at Tokyo National Museum (No. 202). It seems as though the two independent images of Kannon found here were made after a similar model as the attendant bodhisattvas of the triad from Hōryūji.

This cast bronze statue of Kannon with the large transformed Buddha (kebutsu) atop its head is a valuable example of repoussé Buddhas that were used to ornament the interior walls of temple halls. When repoussé images were produced, a bronze plate was laid atop of the matrix and the image was hammered out with a mallet.
