    Momotaro and his friends

    The most famous old tale among the Japanese is most likely Momotaro (桃太郎 in Japanese). The summary of the story is as follows : “A boy, who was born from a peach and came from an upstream, was named Momotaro. When he grows up, he takes some Kibidango (sweet dumpling made with mocha flour and millet flour, 吉備団子 in Japanese), and sets off on a journey to subjugate the Oni (devils, 鬼 in Japanese). On the way, Momotaro finds a dog, a monkey and a Japanese pheasant, and they become his followers. The 4 arrive at Onigashima, (the island of Oni, 鬼が島 in Japanese) where the Onis are waiting for them. After a hard battle, the 4 beat the Onis, and take back the treasures that the Onis stole from the people, and Momotaro brings peace to the world.”
