About this spot
Held on Sunday, August 2, 2026 at 20:00, this offshore fireworks display takes place on the sea about 250 meters offshore from Ajirohama Beach. About 400 fireworks shells launch one after another from offshore in the Sea of Japan, spreading light across the quiet night sea. Though compact in scale, watching the fireworks up close with the sound of the waves gives a sense of presence unique to a seaside fireworks display. As the finale to a day of sea swimming and cool relief beneath the trees, enjoy the fireworks slowly with your family.
