He also goes by other names like Masakatsu-akatsukachi-hayahi-ame-no-oshihomimi which means "Truly Winning Have I Won with Rushing Might Ruling Grand Rice Ears of Heaven".

[1][better source needed] He was born out of a kami-making competition between Amaterasu and Susanoo.

In many versions, Susanoo took Amaterasu's beads and crushed them within his mouth, which created five male kami.

[5][1] The first one to be born was Amenooshihomimi, second was Ame-no-hohi, third was Amatsuhikone, fourth was Ikutsuhikone, and Kumanokusubi was the fifth.

[3][6][7][8] In some versions, Amaterasu gave Amenooshihomimi a bronze mirror, which was called Yata no Kagami.
