The Cult
Hachiman's cult was a state affair from the start. His head shrine at Usa in Kyūshū — three sanctuaries in the distinctive Hachiman-zukuri style — anchored a grand festival and, more consequentially, an oracle: for centuries the court consulted Usa on succession, rebellion, and the casting of the Great Buddha, and the answers moved armies. Iwashimizu, founded south of the capital in 859–60 after an oracle chose the site, was tended as a shrine-temple complex by Buddhist clergy — the medieval jingūji pattern — and its network carried his name along the Inland Sea. Below the great houses, branch shrines multiplied by kanjō invitation until Hachiman altars stood in nearly every province. Peasants prayed to him for harvest and protection; archers for aim; the state for victory.
