Tsukiyomi is a Shinto deity, brother or Amaterasu and Susanowo. He ruled over the moon & night in the Shinto religion. He appears only in two myths, one where he is born opposite his sister, Amaterasu, and with his brother Susanowo, and one where he kills a food goddess.
Tsukiyomi is a very underrated god.
