Naka Shrine
Inside the shrine
The Naka Shrine (南賀ノ神社, Naka no Jinja, literally meaning: Shintō Shrine of Southern Joy) is 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. In there is a tablet containing the clan's secrets. The tablet can only be read with specific dōjutsu, with the Sharingan, Mangekyō Sharingan, and Rinnegan being able to read more than the other, respectively. Here the secrets of the Mangekyō Sharingan are written, as is the story of the Sage of the Six Paths and the Ten-Tailed Beast. To date there has been no mention of Madara Uchiha having Nagato read the tablet before his death.
