Places such as Kannabi (a place such as a mountain or forest where the divine spirit resides), Iwasaka (the area a deity sits) and Himorogi (a temporarily erected altar used as a place of worship) were considered to be borders between the actual world and the sacred area whereby these places were marked with sacred ropes as barriers and, in some cases, became kinsokuchi (a tabooed land).
神奈備（かむなび）や磐境（いわさか）や神籬（ひもろぎ）などは、その神域との端境であると考えられ、結界としての注連縄が張られ、時には禁足地ともなった。
