Izanagi (イザナギ/伊邪那岐/伊弉諾) or Izanaki (イザナキ), formally referred to with a divine honorific as Izanagi-no-Mikoto , is the creator deity (kami) of both creation and life in Japanese mythology. He and his sister-wife Izanami are the last of the seven generations of primordial deities that manifested after the formation of heaven and earth. Izanagi and Izanami are held to be the creators of the Japanese archipelago and the progenitors of many deities, which include the sun goddess Amaterasu, the moon deity Tsukuyomi, and the storm god Susanoo. He is a god that can be said to be the beginning of the current Japanese imperial family.

A creator deity or creator god is a deity responsible for the creation of the Earth, world, and universe in human religion and mythology. In monotheism, the single God is often also the creator. A number of monolatristic traditions separate a secondary creator from a primary transcendent being, identified as a primary creator.
