ShintaiIn Shinto, shintai, or go-shintai when the honorific prefix go- is used, are physical objects worshipped at or near Shinto shrines as repositories in which spirits or kami reside. Shintai used in Shrine Shinto (Jinja Shinto) can be also called mitamashiro. In spite of what their name may suggest, shintai are not themselves part of kami, but rather just temporary repositories which make them accessible to human beings for worship. Shintai are also of necessity yorishiro, that is objects by their very nature capable of attracting kami.
YorishiroA 依り代/依代/憑り代/憑代 in Shinto terminology is an object capable of attracting spirits called kami, thus giving them a physical space to occupy during religious ceremonies. Yorishiro are used during ceremonies to call the kami for worship. The word itself literally means "approach substitute". Once a yorishiro actually houses a kami, it is called a shintai. Ropes called shimenawa decorated with paper streamers called shide often surround yorishiro to make their sacredness manifest.
Iwakura rockIwakura refers to the belief in rocks as Yorishiro containing Kami in ancient Shinto. It also refers to the rock itself, which is the object of worship. Nature worship, also known as spirit worship or animism, is a type of base faith that has been present in Japan since ancient times. This form of worship revolves around the belief in gods and spirits that reside in nature. In Shinto rituals, gods are said to have descended from shintai, a rock, and the yorishiro, called himorogi, was made the center of the ritual, symbolizing the divine power of the gods.
Shinto shrineA Shinto shrine is a structure whose main purpose is to house ("enshrine") one or more kami, the deities of the Shinto religion. The honden (本殿, meaning: "main hall") is where a shrine's patron kami is/are enshrined. The honden may be absent in cases where a shrine stands on or near a sacred mountain, tree, or other object which can be worshipped directly or in cases where a shrine possesses either an altar-like structure, called a himorogi, or an object believed to be capable of attracting spirits, called a yorishiro, which can also serve as direct bonds to a kami.
