Gozu Tennō (牛頭天王, lit. "Ox-Headed Heavenly King") is a syncretic Japanese deity of disease and healing. Originally imported to Japan from mainland Asia, he was regarded since the Heian period both as a causer of and protector against epidemics and eventually became amalgamated with the native kami Susanoo during the medieval and early modern periods. During the Meiji period, when the government mandated the separation of Shinto and Buddhism, Shinto shrines dedicated to Gozu Tennō such as Yasaka Shrine in the Gion district of Kyoto or Tsushima Shrine in Tsushima, Aichi Prefecture officially reidentified their enshrined deity as Susanoo.
