Momotaro - Peach Boy

Momotarō (桃太郎?) is a popular hero from Japanese folklore. His name literally means Peach Tarō; as Tarō is a common Japanese boy's name, it is often translated as Peach Boy.
In the tale, an old couple never where able to have children, and one day when they were fishing on the river, a big peach came to the shore, and when they open it a baby was inside the peach. So that is why the old couple who became their parents named him after the peach.
