Himorogi (神籬; lit. "divine fence") in Shinto terminology are sacred spaces or altars used to worship. In their simplest form, they are square areas with green bamboo or sakaki at the corners without architecture. These in turn support sacred ropes (shimenawa) decorated with streamers called shide. A branch of sakaki or some other evergreen at the center acts as a yorishiro, a physical representation of the presence of the kami, a being which is in itself incorporeal.
During the Aoi Festival in Kyoto the himorogi is a square space surrounded by green branches with an evergreen tree at the center as a yorishiro. A more elaborate himorogi can also be made with a straw mat on the ground with on it a ceremonial 8-legged stand called an hassoku-an (八足案; eight leg an) decorated with shimenawa and sacred emblems.
