The story of Momotarō, the Peach Boy, is a popular Japanese fairy tale.
Once upon a time, there was an old couple. When the woman went to a stream, she spotted a massive peach floating on the water. She took it home so she and her husband could eat it. But when they cut it open, they found a little boy inside - Momotarō. The boy grew up with them like their own son. He was incredibly strong, but also pretty lazy.
Years went by. When a bunch of ogres kept terrorising the village, Momotarō decided to head over to the ogre island and sort out the troublemakers. For provisions, his mum gave him a bag of millet dumplings (kibi dango).
On the way to the island, Momotarō met a monkey, a dog, and a pheasant. He fed them the millet dumplings and became mates with them. Together, they reached the ogre island and beat the ogres.
Momotarō and his mates headed back to the village and lived happily ever after.
