Watch Approximately 3,500 Fireworks Launching Offshore, Lighting Up the Sea

About this spot

An offshore fireworks display held in the Oshima Kamijima/Koe Harbor area on July 25, 2026 (Saturday), 8:00-8:30 p.m. The fireworks, presented as an offering to the Seventeen-Night Festival at Itsukushima Shrine, launch from a platform barge offshore and approximately 3,500 fireworks illuminate the quiet island night sky. This is a special 30-minute experience unique to a small harbor town surrounded by sea, where fireworks echo alongside the sound of waves. The fireworks spreading across the night sky of an island surrounded by water on all sides create an emotional landscape distinctly different from urban fireworks displays, evoking the distinctive character of remote islands.

Tips

In rough weather, the event may be cancelled or postponed, so check the official announcement on the day to confirm. After the fireworks end, the ferry terminal area will be crowded, so confirm return ferry times in advance. Since it will be dark underfoot, a smartphone light is helpful for safety.

Best time to visit

Timed for the 8:00-8:30 p.m. event. Secure your viewing spot along the harbor at least 30 minutes before the start.
