Approximately 2,000 Fireworks Over Ariake Sea, Enjoying Summer Fireworks with the Sea Breeze

About this spot

The Shimabara Onsen Gamadasu Fireworks Festival is a summer tradition where approximately 2,000 fireworks light up the night sky over Ariake Sea. "Gamadasu" is a local dialect term meaning "do one's best," and this festival is beloved by local residents. Fireworks launched from the sea have nothing to obstruct them, and the grand blooming lights open wide across the night sky of vast Ariake Sea, enjoyed directly from the front. Fireworks viewed while breathing in the salt-scented night breeze offer an openness and impact unique to seaside festivals. With the lights of Kumamoto across the water glimmering in the distance, enjoy Shimabara's summer night slowly with your family. After the finale, it's recommended to linger at the harbor until congestion subsides before heading home.
