Bungo Province
The honor of the holiest Shinto shrine of Bungo Province (豊前一宮, "Buzen ichinomiya") was given to Usa Shrine known as Usa Hachimangu or Usa Jingu in Usa district (today Usa, Ōita). Usa shrine had not only religious authority but also political influence to local governance, but their influence was reduced until the Sengoku period.
