En no Ozuno is Banished to Izu Ōshima

En no Ozuno, a notable Japanese mystic and apothecary, faced banishment to the remote island of Izu Ōshima. A significant figure in Japanese spiritual practices, he would later be regarded as the founder of Shugendō, a syncretic religion that combines elements of Shinto and Buddhism. This event marked a pivotal moment in his life, as the banishment was partially due to allegations regarding his spiritual practices and medicine. Izu Ōshima's isolation served as both a punishment and an opportunity for reflection that ultimately shaped his teachings.
