It normally consists of a connecting section linking the honden (sanctuary, closed to the public) to the haiden (oratory).[1] In heiden, offerings (heihaku), consisting of strips of paper or silk or white and red clothing, are offered to the kami.[2]
If the shrine is built in the Ishi-no-ma-zukuri style,[3] its stone pavement is lower than the floor of the other two rooms, and it is called, hence the name.[4] It can also be called or in other ways, and its position can sometimes vary. In spite of its name, nowadays it is used mostly for rituals.
The size of the heiden also varies considerably and there are some exceptions regarding its location. For example, the Naikū heiden at Ise Shrine is located beyond the four walls that surround the sacred quarter.
