Amaterasu's brother, the storm god Susano'o, had vandalized her rice fields, threw a flayed horse at her loom, and brutally killed one of her maidens due to a quarrel between them. In turn, Amaterasu became furious with him and retreated into the Heavenly Rock Cave, Amano-Iwato. The world, without the illumination of the sun, became dark and the gods could not lure Amaterasu out of her hiding place.
