Abstract
In the mid-seventeenth century, nearly all of the temple compounds on Koyasan were managed by Kongobu-ji temple. However, Koyasan of the thirteenth century was divided into three power bases: the Kongobu-ji faction, the Daidenbo-in faction, and the Kangosanmai-in faction. In the periphery of these three factions and not directly connected to any were the hijiri, who formed their own groups on Koyasan. In the thirteenth century the area known at present as Isshin'in-dani was occupied by a temple connected to Ninna-ji called Isshin-in, where hijiri known as shonin lived.
