It is said to be a festival that prays for a bountiful catch and the safety of boats, and has continued for 400 years. After men carry the portable boat back and forth between Furobashi Bridge and the post office, they head to the fishing port. From the fishing port, the portable boat is placed on a ship and sent to Bentenshima, and when it returns from Bentenshima, it is welcomed with fireworks. The area becomes lively with many people, and Kowaurura is enveloped in the excitement of the festival.
