In an alternate writing in the second section of the Kamiumi in Nihonshoki, there is a tale that Wakumusubi who was born of the deity of fire Kagutsuchi and the deity of earth Haniyamahime whom Izanami gave birth immediately before she died, produced silkworm and mulberry from her head and five grains inside her navel.
また、日本書紀における神産みの第二の一書には、火の神カグツチと、イザナミが亡くなる直前に生んだ土の神ハニヤマヒメの間に生まれたワクムスビ（稚産霊）の頭の上に蚕と桑が生じ、臍（ほぞ）の中に五穀が生まれたという説話がある。
