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 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.

Influence

 * Like many Sharigan Jutsu, this jutsu is named after a Shinto Kami. In this case it is Izanagi-no-Mikoto, one of two Kami that bore the islands and other dieties of Japan along with his sister and wife Izanami.
