One day, an old woman is washing clothes at a river when a large peach comes floating down the stream. She brings it home to her husband and, just as they're about to cut it open, out pops a healthy baby boy. The old couple name the boy Momotaro (Peach Boy) and raise him to be a fine young man. One day, Momotaro hears about a band of ogres who are terrorizing surrounding villages. He sets off to conquer them, recruiting a dog, monkey and pheasant as retainers along the way, and does many heroic deeds.
