Which of these is a Japanese folk hero?

Kintarō (often translated as "Golden Boy") 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 Sakata no Kintoki. 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.

Kintarō is supposedly based on a real person, Sakata Kintoki, who lived during the Heian period and probably came from what is now the city of Minamiashigara, Kanagawa. He served as a retainer for the samurai Minamoto no Yorimitsu and became well known for his abilities as a warrior. As with many larger-than-life individuals, his legend has grown with time.
