This annual race is held to continue the tradition of the sabani, a traditional Okinawan sailing boat made of wood and measuring from five to 10 meters in length. The course extends for about 36 kilometers from Furuzamami Beach on Zamami Island to Naha Port. Guided by conditions at sea, participants hoist sails when the wind is blowing and row their boats when the wind dies down. The competitive race is very popular and attracts many spectators every year. One of the highlights of this event is the sight of more than 40 sabani lined up at the starting line.
