Izanagi

Izanagi is a dōjutsu that even the Uchiha clan deemed forbidden. Danzō, with the ten Sharingan implanted in his right arm, is able to use this technique to escape fatal injuries like Amaterasu and Susanoo through as yet unknown means. When this is done, one of the ten Sharingan on his arm closes for every fatal damage that he sustains. This jutsu carries great risk to the user.

Influence
Like many Sharingan jutsu, this jutsu is named after a Shinto kami. In this case it is Izanagi-no-Mikoto, who, together with his sister and wife Izanami-no-Mikoto, created the islands and other deities of Japan.

One of the most famous stories about Izanagi-no-Mikoto tells the tale of how he goes into Yomi, the Japanese underworld, to retrieve Izanami-no-Mikoto after she died giving birth to the Shinto fire god Kagutsuchi-no-Kami. After he fails to retrieve her and leaves Yomi again, he washes himself in a stream. As he cleans his left eye, Amaterasu-Ōmikami is born, as he cleans his right eye, Tsukuyomi-no-Mikoto is born, and as he cleans his nose, Susanoo-no-Mikoto is born.
