Especially in its right elbow lifted up to chest height, the dynamic pose of this dashing statue evokes the Bishamonten at Ganjōjuin Temple in Shizuoka made by the famous Buddhist sculptor Unkei (?–1223) in 1186. Armor protecting the neck made from a different kind of wood hangs down from the helmet by chains. This statue comes from the Hōtōin (a.k.a. the Kototō) at Iwashimizu Hachimangū Shrine in Kyoto.

This statue originally came from Iwashimizu Hachimangū Shrine in Kyoto Prefecture. The masculine expression suggests that the Buddhist sculptor who was influenced by Kei school made this work. Gold paint has been broadly applied and depicted more figurative motives such as cloud with dragon, phoenix and flower with leaf, instead of geometric pattern. The lappet of the helmet (Shikoro) was carved from a different wood and it was hooked by chains.
