In this worldview, the world is divided into realms; Utsushiyo, the actual world, the world of the living, Tokoyo (the perpetual country), also called Tokkoyo (eternal night), and the sacred world called Kakuriyo (the eternal, forever unchanging, distant land over the sea, or the world of the dead, or heaven).
世界観においては、現世（うつしよ）という現実世界と、常世・常夜（双方とこよ）または、幽世（かくりよ）といわれる神域に別れる。
