Shinto
In Shinto, altars are found in shrines. Originating in ancient times, himorogi are temporarily erected sacred spaces or "altars" used as a locus of worship. A physical area is demarcated with branches of green bamboo or sakaki at the four corners, between which are strung sacred border ropes (shimenawa). In the center of the area a large branch of sakaki festooned with sacred emblems (hei) is erected as a yorishiro, a physical representation of the presence of the kami and toward which rites of worship are performed.
In more elaborate cases, a himorogi may be constructed by placing a rough straw mat upon the ground, then erecting a ceremonial eight-legged stand (hakkyaku an) upon the mat and decorating the stand with a framework upon which are placed sacred border ropes and sacred border emblems. Finally the sakaki branch is erected in the center of this stand as the focus of worship.
