In Japanese mythology, the story of the birth of the gods occurs after the creation of Japan (Kuniumi). It concerns the birth of the divine (kami) descendants of Izanagi and Izanami.
According to the Kojiki, various gods were born from the relationship between Izanagi and Izanami until the fire deity, Kagu-tsuchi, at birth burned Izanami's genitals and wounded her fatally. Izanagi, witnessing the death of his beloved wife, in rage took the ten-grasp sabre and crushed his child, Kagutsuchi. A number of gods were born from the blood and remains of Kagutsuchi. Subsequently, Izanagi went to the land of Yomi (the world of the dead) to find Izanami, however when he found her, she had become a rotting corpse and from her parts other gods had arisen, causing the flight of Izanagi to the world of the living. Then Izanagi performed the misogi ritual purification through which more gods are born. The last of these are the three most important gods of Shinto: Amaterasu, goddess of the sun; Tsukuyomi, deity of the moon; and Susano'o, god of the sea.
After having created the Eight Large Islands (Ōyashima) and other islands during the creation of Japan, Izanagi and Izanami decided to give birth to other gods, among them household deities, deities of the wind, trees and meadows, all born spontaneously:
