Minamoto no Yorimitsu
is a folk hero from Japanese folklore. A child of superhuman strength, he was raised by a yama-uba ("mountain witch") on Mount Ashigara. He became friendly with the animals of the mountain, and later, after catching Shuten-dōji, the terror of the region around Mount Ōe, he became a loyal follower of Minamoto no Yorimitsu under the new name . He is a popular figure in Bunraku and kabuki drama, and it is a custom to put up a Kintarō doll on Boy's Day in the hope that boys will become equally brave and strong.
