The Yamagawa port which is famous for bonitos holds a festival invoking the prosperity of the port and safe sailing.
Some events such as a fireworks display (June 3rd 20:00 ~), fishing boat parades (June 4th, 8:30 ~9:30), dance parades (June 4th 10:10 ~ 11:40), and other things will be held.
Catching live fish with your bare hands (June 4th 14:30 ~ / children only / there is a charge / The tickets are sold at the port) is especially worth joining!
