Kintarou was a very strong even when he was still a baby, he lived in the mountains with his mother. His mother made him a red haragake with the kanji "gold" (金 Kin) on it. He often wore the haragake and brought his axe with him when he went outside to play. He made friends with the animals in the forests, and they often played sumo together. No one can ever beat Kintarou. A bear that was very proud of its strength once challenged Kintarou to a match. The bear launched at him, but Kintarou easily grabbed and threw the bear onto the ground.
One day, Kotarou and his animal friends reached a cliff overlooking a large river. There was no bridge to go across. The bear tried to knock over a tree to make a bridge, but was unable to do so. When it's Kintarou's turn, he easily uprooted the tree and placed it across the cliff. A samurai passing by saw the scene and was impressed by Kintarou's strength.
