Tsukiyomi is the god of the moon in Shintoism and Japanese mythology. Tsukiyomi was born while Izanagi was bathing himself after escaping the underworld and the clutches of Izanami. Tsukiyomi was washed out of Izanagi's right eye. Tsukiyomi angered Amaterasu, the sun goddess, when he killed Uke Mochi. She refused to ever face him in the heavens again, forever separating day and night.
