Amaterasu (
literally "Shining Heaven"), is a technique used by Uchiha Itachi while enabling the Mangekyou Sharingan. It is named
after the Shinto sun goddess, Amaterasu. This jutsu is fire-element ninjutsu of
the highest order and creates unquenchable jet-black flames said to be as hot as the sun and capable of burning for seven days and seven nights, as well as through any material.
