Amaterasu

Amaterasu is the highest level Fire Release technique, as well as one of the most powerful ninjutsu in existence. It is said to represent the, the antipode to Tsukuyomi, a genjutsu of similar power and a fellow Mangekyō Sharingan dōjutsu.

The jet-black flames of the Amaterasu; said to be as hot as the sun, ignite whatever the user looks on, either a specific point, or anything in the user's field of vision. They're unavoidable as long as the user keeps their eyes focused on their target. The flames are extremely powerful, capable of burning through anything and can even smother regular flames easily. Amaterasu is said to burn for seven days and seven nights, and cannot be extinguished with water or any other normal methods. Use of the technique also puts a great deal of strain on the user, causing the eyes to bleed. After gaining the Mangekyō Sharingan, Sasuke Uchiha has shown that not only could he extinguish the flames at will but he could even manipulate the flames themselves as well.

Influence
As from the ancient Japanese myth and religion of Shintoism Amaterasu, Tsukuyomi, and Susanoo are all gods. When Izanagi washed his face after escaping the underworld his left eye became the Sun Goddess, Amaterasu.
