From Japanese Folklore
Shokuro, in order to stand well with Toru, the magistrate of his district, promised him that he would catch the Thunder God. “If,” said Shokuro, “I were to tie a human navel to the end of a kite, and fly it during a stormy day, I should be sure to catch Raiden, for the Thunder God would not be able to resist such a repast. The most difficult part of the whole business is to secure the meal.”
With this scheme in view Shokuro set out upon a journey in quest of food for the Thunder God. On reaching a wood he chanced to see a beautiful woman named Chiyo. The ambitious Shokuro, without the least compunction, killed the maid, and, having secured his object, flung her corpse into a deep ditch. He then proceeded on his way with a light heart.
Raiden, while sitting on a cloud, happened to notice the woman’s body lying in a ditch. He descended quickly, and, being fascinated by the beauty of Chiyo, he took from his mouth a navel, restored her to life, and together they flew away into the sky.
Some days later Shokuro was out hunting for the Thunder God, his kite, with its gruesome relic, roaring high over the trees as it flew hither and thither in a strong wind. Chiyo saw the kite, and descended nearer and nearer to the earth. At last she held it in her hands and saw what was attached. Filled with indignation, she looked down in order to see who was flying the kite, and was much astonished to recognise her murderer. At this juncture Raiden descended in a rage, only to receive severe chastisement at the hands of Shokuro, who then made his peace with Chiyo, and afterwards became a famous man in the village.
