Izanagi is a dōjutsu that has the power to connect illusion and reality, which the Uchiha clan deemed forbidden due to the terrible consequences of its use. However, according to Madara Uchiha, only those who possess and can control the powers of both the Uchiha and Senju are capable of utilizing the complete form of this particular technique.
Izanagi is a genjutsu that's meant to be cast on oneself instead of others, and it's the most powerful among such genjutsu. When activated, the caster removes the boundaries between reality and illusion within their personal space. To a degree, this allows the user to control their own state of existence. The actual effects of Izanagi vary from user to user, dependent on their level of dominance over the required bloodlines, but all seem to involve the ability to deem negative events an illusion and positive events a reality, in regard to themselves.
When Izanagi is activated, it is capable of turning injuries and even death inflicted upon the user into mere illusions. Whenever the user receives a fatal injury, their body fades away as a genjutsu. The user then returns back to reality, physically real and unscathed. Danzō, in an effort to make practical use of the jutsu, had ten Sharingan embedded onto his right arm. This allows Danzō to increase the length of time that Izanagi can stay active, as well as the number of times he could use it in succession. However, not being of Uchiha blood, this technique requires substantial amount of chakra for Danzō to use, which is made possible only by the transplant of Hashirama Senju's DNA to increase his energy.
Though the sustained time of the jutsu can greatly differ between individuals, Danzō is implied to have had Orochimaru forcibly extend the time it takes for each eye to close to as long as one minute. After the aforementioned time, the eye used to activate Izanagi will permanently close and be stricken with blindness forever, which is not at all unlike Mangekyō Sharingan overuse-induced blindness. It is this side effect of Izanagi that caused the Uchiha to label the technique a kinjutsu.
The Sage of the Six Paths is said to have also been able to manipulate this respective technique, as he bore the origins behind the two necessary bloodlines, most notably using the ability in order to create the nine tailed beasts from the chakra of the Ten-Tailed Beast. As stated by Madara Uchiha; the exact process he utilized initially involved the administration of imagination, and the spiritual energy which forms the basis of "yin" chakra to create shape and form from nothingness. Then through the application of vitality, and the physical energy which forms the basis of "yang" chakra, he would breath life into the prior form. Thus a technique with the power to turn imagination into reality was born, known as Izanagi.
Like the various jutsu used with the Sharingan, 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.
