Kumano's biggest festival, and actually one of the biggest fireworks festivals in Japan, occurs on August 17th of every year. People come from all over Japan, clogging the trains and highways, camping out on the beach and in the Aeon department store, just for this day. Fireworks will shake the ground, take up the entire horizon, and last for hours and hours. Takes place on Kumano's endless coastline at about 7pm, but don't expect any space on the beach for a big group unless you come early, as the town's residents began to stake out their own spaces by tying down tarps on the beach days before. Prime space can be reserved online, but it's easy to see from anywhere on the beach. If you will be coming by train, it is recommended you reserve limited express tickets two weeks in advance.
