View Approximately 2,500 Fireworks Launching Over the Shomei River from the Riverside

About this spot

The Isahaya Mantoro Kawa Matsuri (諫早万灯川まつり), held annually in summer along the Shomei River, is Isahaya City's summer festival tradition, with approximately 2,500 fireworks lighting up the night sky. Fireworks launched from above the river appear large and centered from the riverside, with light shimmering on the water's surface creating an enhanced nighttime waterside atmosphere. As the fireworks explode, the sound resonates through the city, and the festive energy blends with the summer night air in an unforgettable way. The rapid-fire finale leading to the climax has impressive power fitting to conclude this day's journey. From the viewing point you scouted during the daytime, enjoy the fireworks together with the river.

Tips

Check official announcements from Isahaya City or the festival organizing committee regarding whether the event will proceed in case of bad weather. After the show ends, roads from the Shomei River area toward Isahaya Station become very congested. It's recommended to enjoy the lingering atmosphere along the river for a while rather than rushing to leave immediately, then depart with a time delay. Confirm your return parking or public transportation schedules in advance.
