The Naka Shrine

A shrine in Konoha. In the main hall, beneath the seventh tatami mat from the far right, is a secret meeting place of the Uchiha clan. Only the Uchiha can know about. In there is a tablet containing the clan's secrets. The tablet can only be read with specific dôjutsu, with the Sharingan, Mangekyô Sharingan, and Rinnegan being able to read more than the other, respectively. Here the secrets of the Mangekyô Sharingan are written, as is the story of the Sage of the Six Paths and the Ten-Tailed Beast.
