Hachiman shrines A syncretic entity worshiped as both a kami and a Buddhist daibosatsu, Hachiman is intimately associated with both learning and warriors. In the sixth or seventh century, Emperor Ōjin and his mother Empress Jingū came to be identified together with Hachiman. First enshrined at Usa Hachiman-gū in Ōita Prefecture, Hachiman was deeply revered during the Heian period. According to the Kojiki, it was Ōjin who invited Korean and Chinese scholars to Japan, and for this reason he is the patron of writing and learning. Because as Emperor Ōjin he was an ancestor of the Minamoto clan, Hachiman became the of the Minamoto samurai clan of Kawachi (Osaka).

The same three kami are enshrined elsewhere in the network, sometimes under a different name. However, while Munakata Taisha enshrines all three in separate islands belonging to its complex, branch shrines generally do not; which kami they enshrine depends on the history of the shrine and the myths tied to it. Tenjin shrines The Tenjin shrine network enshrines 9th-century scholar Sugawara no Michizane. Sugawara had originally been enshrined to placate his spirit, not to be worshiped. Michizane had been unjustly exiled in his life, and it was therefore necessary to somehow placate his rage, believed to be the cause of a plague and other disasters. Kitano Tenman-gū was the first of the shrines dedicated to him. Because in life he was a scholar, he became the kami of learning, and during the Edo period schools often opened a
