Izanami

Izanami is an ultimate dōjutsu of the Uchiha clan, in that it is capable of affecting an opponent regardless of their five senses. However, in exchange for the temporary ability that it grants the user, the Sharingan with which Izanami is cast becomes blind.

According to Itachi Uchiha, this technique is on par with Izanagi but unlike the latter, which is a technique capable of altering destiny, Izanami is instead one that decides it.

Influence
Like the various techniques used with the Sharingan, this technique is named after a Shintō god. In this case, it is Izanami, who, together with her brother and husband Izanagi, created the islands and other deities of Japan.

One of the most famous stories about Izanami tells the tale of how Izanagi goes into Yomi, the Japanese underworld, to retrieve her after she died giving birth to the Shinto fire god Kagutsuchi. In Yomi, he manages to get Izanami and they both try to leave, however Izanagi was not supposed to look at her before they escape. Right before they reach the exit, Izanagi looks back and sees her in a decayed form. Frightened, Izanagi flees from Yomi and blocks the cave. Izanami curses Izanagi saying that she will kill 1000 people per day. In response, Izanagi says that 1500 people will be born each day.
