2026 Kozushima Nagisa Fireworks Festival - Full-Day Course

This full-day course centers on the Kozushima Nagisa Fireworks Festival, held on Monday, August 3, 2026, letting you enjoy the whole of Kozushima in the Izu Islands. During the day, pay your respects at Awamikoto Shrine, the island's guardian shrine, and peer into the exceptionally clear sea from the Akasaki Promenade along the cliffs. Before evening, take a swim in the shallow waters of Takoh Bay Beach, and once the sun starts to lean, move to the village near the harbor to have dinner and secure a spot. At night, look up at fireworks rising into the sky right beside the pier at Kozushima Port (Maehama Port), accompanied by the sound of the waves. This plan lets you fully enjoy a summer day surrounded by blue sea, with a quietness found only on an island reachable solely by boat.
