[1] Kagutsuchi's birth burned his mother Izanami, causing her death.
His father Izanagi, in his grief, beheaded Kagutsuchi with his sword, Ame no Ohabari (天之尾羽張), and cut his body into eight pieces, which became eight volcanoes.
Kagutsuchi's corpse created numerous deities, which typically includes Watatsumi, Kuraokami, Takemikazuchi, Futsunushi, Amatsu-Mikaboshi, and Ōyamatsumi.
[2][3] Kagutsuchi's birth, in Japanese mythology, comes at the end of the creation of the world and marks the beginning of death.
[4] In the Engishiki, a source which contains the myth, Izanami, in her death throes, bears the water goddess Mizuhanome, instructing her to pacify Kagu-tsuchi if he should become violent.
