Amaterasu is the sister of Susano'o, the god of the sea and storms, and of Tsukuyomi, the god of the moon. All three were created from Izanagi, when he washed his face to clean the dirtiness of Yomi, the underworld. Amaterasu was born when Izanagi washed out his left eye, Tsukuyomi was born from the washing of the right eye, and Susano'o from the washing of the nose.
