Gion cult

Gion worship (祇園信仰, Gion shinkō) is a Shinto cult. Originally it revolved solely around Gozu Tenno, but during the Separation of Shinto and Buddhism of the Meiji era the government mandated it shift to revolving around Susanoo.

The main shrines are Yasaka Shrine in Kyoto, Hiromine Shrine in Hyogo Prefecture, and Tsushima Shrine in Aichi Prefecture

There are many other cults of Susanoo that are not derived from the Gion faith, but rather from indigenous Shinto traditions without Buddhist influence.^{[citation needed]} These include Susa Shrine, and Yaegaki Shrine.^{[citation needed]}

Gozu Tenno was originally a Buddhist-style Onmyōdō deity, and is generally considered to be the guardian deity of Jetavana, the monastery where the Buddha studied.

According to legend, from the 6th to 7th centuries CE, Hōdō traveled from India through China and the Korean kingdom of Baekje and eventually arrived in Japan. He is recognized as the founder of temples in the mountains of Harima Province and is associated with several chokugan-ji (勅願寺), Buddhist temples built at the request of the reigning emperor.

Tradition holds that when Hōdō came to Japan, he was accompanied by the deity Gozu Tennō (牛頭天王; Sanskrit: Gośīrṣa devarāja), who was later enshrined at Hiromine Shrine and Yasaka Shrine and is venerated in the Gion faith.

While engaged in ascetic practice on Mount Rokkō at the Kumoga Iwa Rock (雲ヶ岩), Hōdō is said to have been approached by the deity Vaiśravaṇa riding on purple clouds. It was after this encounter that Hōdō built Tamon-ji in Hyōgo Prefecture to enshrine the Kumoga Iwa Rock, Rokkō-Hime-Daizen-no-Kami (六甲比命大善神), and the Shinkyō Iwa Rock.

The description in Shinnaiden [ja] is prominent. In China, he was influenced by Taoism, and in Japan, he further merged with Susanoo, the Kami of Shinto. This is because both Gozu Tenno and Susanoo were considered to be plague gods. He was considered to be the Buddha Bhaisajyaguru.
