Kagutsuchi's birth burned his mother Izanami, causing her death. His father Izanagi, in his grief, beheaded Kagutsuchi with his sword, Ame no Ohabari, and cut his body into eight pieces, which became eight volcanoes.The blood that dripped off Izanagi's sword created a number of deities, including the sea god Watatsumi and rain god Kuraokami.

Kagutsuchi's birth, in Japanese mythology, comes at the end of the creation of the world and marks the beginning of death. In the Engishiki, a source which contains the myth, Izanami, in her death throes, bears the water god Mizuhame, instructing her to pacify Kagutsuchi if he should become violent. This story also contains references to traditional fire-fighting tools: gourds for carrying water and wet clay and water reeds for smothering fires
