Amaterasu is a Mangekyō Sharingan dōjutsu and the highest level Fire Release technique. According to Zetsu, it is one of the most powerful ninjutsu in existence. It is said to represent the "Material World and Light" (物質界と光, Busshitsukai to Hikari) and is the antipode to Tsukuyomi. It was also known as Hinokagutsuchi (火之加具土命, Added Tool Earth Lord of Fire) by Indra Ōtsutsuki.
The jet-black flames of the Amaterasu, said to be the fires from hell that are as hot as the sun, ignite at the focus of the user's vision. They're unavoidable as long as the user keeps their eyes focused on their target. The flames are capable of burning through anything in their path, even smothering regular fire techniques with ease. Amaterasu is said to burn for seven days and seven nights, and cannot be extinguished with water or any other normal methods. However, the flames burn fairly slowly, allowing anyone struck by Amaterasu an opportunity to remove whatever or body parts have been caught ablaze. Use of the technique also puts a great deal of strain on the user, usually causing their eyes to bleed.
It has been shown that users of this technique can seal it into another person's Sharingan to be set off by a certain visual, such as a specific target, for a one-off attack. Generally, users of this technique merely cast it and can quench the flames with enough control. However, the flames can be controlled if the user possesses the power of Blaze Release: Kagutsuchi in their other eye, being able to use the flames for a variety of purposes.
- Amaterasu, like Tsukuyomi and Susanoo, is a god in ancient Japanese myth and the Shintō religion. Amaterasu, the Sun Goddess, was born from the left eye of Izanagi when he performed the cleansing ritual after escaping the underworld.
- In the anime, Indra Ōtsutsuki used a technique that was later named Hinokagutsuchi by Naruto: Shinobi Collection Shippū Ranbu. However, as it is virtually identical to Amaterasu, the two techniques shall be treated as the same ability on Naruto Fanon.
