Yasaka Magatama

Using the complete form of Susanoo, Itachi creates the Yasaka Magatama with its right arms, consisting from three tomoe bound together through their centre's by a single circular chakra thread. Due to this structure, the tool acts in a similar manner to that of a shuriken when thrown by Susanoo, rapidly spinning towards the intended opponent until its ultimate collision. Itachi asserts that this is his strongest long-range technique.
