The Naka River (南賀ノ川, Naka no Kawa, Literally meaning: River of Southern Joy) is a river flowing through Konohagakure. The river is located on the land where the Uchiha clan once lived and prospered[1] and at some point, it passes through a deep ravine. It was at this river that Shisui gave Itachi his Sharingan and "erased his existence", but it was thought that Itachi had drowned him.
