The Hamamatsu festival is famous for its large kites. At 11 am on May 3, more than 100 large kites fly in the sky. The kite holders stand at the Nakataima Sand Dunes and release them all at the same time, signaled by a trumpet call. The Nakatajima Sand Dunes, is one of three largest sand dune areas in Japan. The Nakatajima Dunes overlook Enshu-nada sea, so the place has the strong winds needed for flying kites. The kites are decorated with baby boys' names and marks or designs of each town ("chō)". People believe that the higher the kites fly, the healthier the baby boys grow up.
