Kumano Grand Fireworks Display — Co-starring of Oni Castle rocks and maritime fireworks
The Kumano Grand Fireworks take place at Shichirimihama Beach in Kumano City, Mie Prefecture, on Monday, August 17, 2026, from 19:00 to 21:30. Set against the open sand beach facing the Kumano Nada and the nationally scenic Onigajo rocks, about 10,000 fireworks light up the sky and the sea, drawing some 120,000 visitors. The signature is the 'kaijo jibaku' — shells detonated on the sea itself, including a 3-shaku shell spreading about 600 meters wide and two boats tossing shells into the water to burst. The venue is a 5-minute walk from JR Kumano-Shi Station; parking is 2,000 yen per day (some 3,000).
The Kumano Grand Fireworks, one of Japan's best-known seaside displays, light up Shichirimihama Beach in Kumano City on Monday, August 17, 2026, from 19:00 to 21:30. About 10,000 shells rise with the Kumano Nada and the nationally scenic Onigajo rocks behind them, drawing roughly 120,000 visitors. What sets this festival apart is fireworks detonated on the sea itself: a 3-shaku shell bursting into a ring about 600 meters across, and two boats throwing shells into the water one after another to explode them on the surface — a spectacle unlike anything launched from land. The venue is a 5-minute walk from JR Kumano-Shi Station; by car it is about 50 minutes (25 km) south of the Kisei Expressway Owase-Kita IC on Route 42, and restrictions are planned on the Kumano-Owase road that day, so allow extra time. Parking is 2,000 yen per day (some 3,000), and paid seats are best bought in advance.
