Hachiman - Samurai Worship

Samurai Worship

Because as Emperor Ōjin he was an ancestor of the Minamoto clan, Hachiman became the tutelary kami (氏神, ujigami?) of the Minamoto samurai clan. Minamoto no Yoshiie, upon coming of age at Iwashimizu Shrine in Kyoto, took the name Hachiman Taro Yoshiie and through his military prowess and virtue as a leader, became regarded and respected as the ideal samurai through the ages. After Minamoto no Yoritomo became shogun and established the Kamakura shogunate, Hachiman's popularity grew and he became by extension the protector of the warrior class the shogun had brought to power. For this reason, the shintai of a Hachiman shrine is usually a stirrup or a bow.

Throughout the Japanese medieval period, the worship of Hachiman spread throughout Japan among not only samurai, but also the peasantry. So much so was his popularity that presently there are 25000 Shinto shrines in Japan dedicated to Hachiman, the second most numerous after shrines dedicated to Inari. Usa Shrine in Usa, Oita prefecture is head shrine of all of these shrines and together with Iwashimizu Hachiman-gū, Hakozaki-gū and Tsurugaoka Hachiman-gū, are noted as the most important of all the shrines dedicated to him.

The crest of Hachiman is in the design of a mitsudomoe, a round whirlpool or vortex with three heads swirling right or left. Many samurai clans used this crest as their own, ironically including some that traced their ancestry back to the mortal enemy of the Minamoto, the Taira of the Emperor Kammu line (Kammu Heishi).
