Kamiumi

In Japanese mythology, the story of the birth of the gods (神産み, Kamiumi) occurs after the creation of Japan (Kuniumi) and refers to the birth of the 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, Kagutsuchi, 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 Susanoo, 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:

During Kagustuchi's birth, Izanami's genitals were burned and she was mortally wounded. In her agony, from her vomit, urine and feces more gods were born.

After the agony, Izanami dies. At the time Izanagi crept moaning about the body and mourned her death. From his tears Nakisawame () was born. Subsequently Izanagi buried Izanami on Mount Hiba. His sadness turned into anger and he decided to kill Kagutsuchi with a ten-grasp sword called Ame-no-ohabari (, also known as Itsu-no-ohabari).
