As a port, Kuchinotsu began to flourish upon the arrival of the European traders. The town owes much to the sea so each year a Marine Festival is held.
The festival is held over two days. The first, taking advantage of the cooler evening temperatures, includes the opening ceremony, a parade of fishing boats and various performances. The events on day two include a dragon boat race and fireworks display with 2,600 fireworks launched over the sea in the evening to round things off.
