Usa Jingū (宇佐神宮), also known as Usa Hachimangū (宇佐八幡宮), is a Shinto shrine in the city of Usa in Ōita Prefecture in Japan. Emperor Ojin, who was deified as Hachiman-jin (the tutelary god of warriors), is said to be enshrined in all the sites dedicated to him; and the first and earliest of these was at Usa in the early 8th century.
