Because the standing statue of Fudo Myoo in Joraku-ji Temple in Kanagawa Prefecture, which was made by Unkei at nearly the same time of the Fudo Myoo statue in Ganjoju-in Temple, was shaped with heaven-and-earth eyes although its body was virtually identical to that of the statue in Ganjoju-in Temple, it seems that Unkei distinguished facial expressions.
願成就院の不動明王像とほぼ同時期に運慶が制作した、神奈川県・浄楽寺の不動明王立像は、胴部が願成就院とほぼ同一の造形であるものの顔面が天地眼の相で彫られていることから、運慶が相の彫り分けを行っていたことが伺える。
