History

According to tradition, the site began as Kosuge-yama Ganryu-ji, a Shugendo temple said to have been founded by En no Ozunu. Through repeated decline and rebuilding it carried on as a sacred site, and after the separation of Shinto and Buddhism in the Meiji era it became the present Kosuge Shrine. The premodern temple and the modern shrine are understood as one continuous history under the name of the holy mountain Kosuge-yama.
