He was fourth born of the five children of the jewels of Amaterasu.[4][5] In another version he comes from Susanoo-no-Mikoto's jewels directly and is thus his son.[1]
Birth
He was born out of a kami-making competition between Amaterasu and Susanoo. In many versions of the story, Susanoo took Amaterasu's beads and crushed them within his mouth, which created five male kami.[6][7] The first one to be born was Ame-no-oshihomimi, second was Ame-no-hohi, third was Amatsuhikone, fourth was Ikutsuhikone, and Kumanokusubi was the fifth.[5][8]
