Daiitoku Myōō (Skt. Yamāntaka) is one of the Five Wisdom Kings of the esoteric Buddhist pantheon, though icons of this powerful deity were occasionally made as an independent icon. This deity was the principal icon used in prayers to repel the enemies of Buddhism or to achieve victory in warfare. Its tempered mode of carving and the sense of tranquility to the entire statue exemplify the style of images made in the latter part of the Heian period (794–1185).
