Shinto Creation Myth
At the beginning of time, all matter that would become the world was mixed together in a great cloud. The lighter components rose up and became heaven, and the heavier parts descended and became a thick ocean of muddy water. A green sprout began to grow, and when it flowered the First God burst forth from it. This first god created Izanagi, the god of all that is light and heavenly, along with his wife and sister Izanami.
This First God gave Izanagi the task of finishing the creation of the world. Standing on a rainbow, Izanagi and Izanami plunged a jewel-crested spear into the ocean and stirred it. When they pulled it free, the water that dripped from the spear coagulated and formed the first island of Japan. The gods went down to the island, and from there created the rest of the Japanese archipelago.
