He sails down river to the city, where he asks for a job with the government and goes to the home of a rich "daimyo" (lord), whose daughter is an attractive princess. They say no because he is so tiny, but give him a job entertaining the princess. While they travel together, they are attacked by a big monster that swallows Issun-boshi. The boy defeats the monster by pricking him from within with his needle/sword. The monster spits out Issun-boshi and drops a magical Uchide's Mallet as he runs away. As a reward for his bravery, the princess uses the power of the mallet to make him grow. Issun-bōshi and the princess stay friends and get married later.
