legend

At the dawn of time, Susano-o, the spirit of the sea and storms, was making ready to leave heaven and to gush down to Earth. His sister, the far-shining Sun Goddess, said, “Oh, impetuous brother of mine. Before you go, let us exchange tokens of our love and affection for one another.” Susano-o bowed to his sister, drew his sword from his side, and presented it to her. She accepted the gift, and then chewed off pieces of the metal blade in her mouth, before spitting them out.
