Approximately 10,000 fireworks illuminate the night sky above the Usui River—the climax of the Ichinoseki Summer Festival

About this spot

The Usui River Opening Fireworks Festival, featuring the finale of the Ichinoseki Summer Festival, is one of Tohoku's premier summer celebrations, with approximately 10,000 fireworks launching from upstream and illuminating the night sky. Viewed from the riverside park, the fireworks burst directly overhead with tremendous impact, and the ribbon of light reflecting on the water's surface creates beauty unique to riverbank fireworks displays. Each succession of starbursts and large shells draws cheers, and the final climax delivers thunderous salvos overlapping with the river's flow, creating an awe-inspiring grand finale resonating through your entire body. Completing a full day's journey with the Usui River that began with the clear stream of Genbikei, this memorable 75 minutes stands as a fitting conclusion.

Tips

Check with Ichinoseki City's official announcement or the festival's official information on the day for any weather-related cancellations. After the show ends, the area around the venue and the road to Ichinoseki Station become very crowded—enjoy the afterglow where you are before moving with time lag. Check the final train and bus departure times in advance and plan with time to spare. A small light is useful for the dark riverbed path on the way back.
