Named after the Shinto Sun Goddess, 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 is a fellow Mangekyō Sharingan dōjutsu, said to represent the. Itachi Uchiha was the first person to be shown to be able to use Amaterasu. He later gave the power to Sasuke Uchiha.

The jet-black flames of the Amaterasu are said to be as hot as the sun. The flames are extremely powerful, capable of burning through Jiraiya's Summoning: Toad Mouth Bind, which Jiraiya stated to be fire resistant. Not surprisingly, it appears to use a large amount of chakra. Though said in the data book to burn everything reflected on its retina, Zetsu also commented that the Amaterasu burned everything within Itachi's wide field of vision to cinders with an unholy black flame, to the degree of being able to burn an entire forest or village with it. It can even smother regular flames easily. Wherever the user focuses his eye, the flames will appear at the exact spot without moving, making it unavoidable as long as the user keeps his vision trained on the target. The flames are said to burn for seven days and seven nights, and cannot be extinguished with water or any other normal methods. However, it can be extinguished by the user's alternate eye. Jiraiya managed to seal some Amaterasu flames with Fire Sealing Method.



During the battle between Itachi and Sasuke, after Sasuke escaped Tsukuyomi, all genjutsu between the brothers became pointless. Itachi was forced to shift from his most powerful genjutsu to his most powerful ninjutsu. As opposed to Tsukuyomi, which originated in Itachi's left eye, the Amaterasu came from his right eye. Although not shown in its entirety when used while escaping Jiraiya, in the battle with Sasuke, Itachi's eyes were strained to the point that he drew tears of blood while executing Amaterasu.

When Sasuke met Madara Uchiha, Itachi's Mangekyō Sharingan automatically used Amaterasu. Madara later explained that Itachi had implanted Amaterasu in Sasuke's eye to detonate upon seeing Madara's Sharingan. Sasuke used his own Amaterasu whilst fighting Kirābī, but used his left eye as opposed to Itachi, who had used his right. Like Itachi's, his eyes began to bleed as well. After Karin was accidentally hit with Amaterasu, Sasuke used his right eye to suppress the flames, and did the same with Kirābī.
