Kumano Fireworks Festival 2026 Turns a World Heritage Beach Into Japan’s Most Resonant Summer Stage
On 17 August 2026, Kumano’s long pebble shore and the cliffs of Onigajo come together for a hanabi night that feels beautifully unlike a city fireworks show. With sea-launched shells, 300 years of memory, and a beach that runs for more than 20 kilometres, this is summer in Japan at its most specific and unforgettable.
