Experience a summer night in Mizugo Oe where lantern floating and fireworks overlap

About this spot

The Mizugo Oe Summer Festival Lantern Floating and Fireworks Display is Oe Town's signature summer festival, combining the tradition of floating lanterns on the Mogami River on August 15, the day the war ended, to honor the war dead, with a fireworks display. The light of countless lanterns flowing across the water's surface illuminates the nighttime Mogami River quietly and beautifully. When the fireworks launch begins at 7 PM, the flickering light of the lanterns and the light of the fireworks overlap above the Mogami River, creating a uniquely fantastical sight that cannot be experienced at other fireworks displays. Fireworks launched from the Mogami River surrounded by the Yamagata countryside reflect in the water's surface and bloom large in the night sky, creating brilliant flowers of light in the clear summer night air. The time spent quietly viewing the fireworks as a family while sensing the meaning of prayer embodied in the lantern floating becomes a cherished memory of summer.

Tips

Check the official announcement from Oe Town beforehand regarding whether the event will be held in case of bad weather. After the display ends, surrounding roads become congested, so it's recommended to wait a bit before leaving after the fireworks finish. The floodplain has areas with minimal lighting, so be sure to bring a small light. Confirm the schedule of return transportation in advance.

Best time to visit

During the 7:00 PM to 8:50 PM event hours. From just after sunset when the lanterns begin to spread across the water's surface through the fireworks finale, the time is unforgettable.
