Interior Shrine of Iyemitsu (Haiden), Nikko
There are no images in Shinto shrines, and the sole object that the people look up to during their worship is a round metal mirror hanging on the wall. The mirror is, as I understand it, supposed to represent the idea of truth, and also the idea of finding ones god in ones self.
