Flow of the course
About this spot
The Shimabara Onsen Gamadasu Fireworks Festival is a summer tradition in which about 2,000 fireworks color the night sky over the Ariake Sea. 'Gamadasu' is a word in the Shimabara dialect meaning 'to do one's best,' and the festival has long been loved by local residents. Fireworks launched from the sea have nothing to obstruct them, so you can enjoy the great blossoms of light opening head-on in the wide night sky over the Ariake Sea. Watching the fireworks under a night breeze carrying the scent of the sea has an openness and impact unique to a seaside festival. Enjoy a leisurely summer night in Shimabara with your family while gazing at the distant lights of Kumamoto on the opposite shore. Once the finale ends, it's a good idea to relax around the harbor and enjoy the afterglow until the crowds thin out before heading home.

Tips
Check the festival's official announcements or information from Shimabara City for whether the event will proceed in bad weather. The start time is not yet fixed, so check the day's event information in advance. After the event, roads around Shimabara Outer Port and toward Shimabara Station get congested, so it's safer to head home a bit later than everyone else. It gets dark underfoot, so use a small flashlight or your smartphone's light.
Best time to visit
Timed to the festival's schedule. Settle into your viewing spot 20-30 minutes before the start
