2026 Suigo Oe Summer Festival Lantern Floating and Fireworks Display (水郷大江夏まつり灯ろう流し花火大会): A Full-Day Course

This full-day course is centered on the Suigo Oe Summer Festival Lantern Floating and Fireworks Display (水郷大江夏まつり灯ろう流し花火大会), held on Saturday, August 15, 2026, and lets you enjoy the nature of Oe Town (大江町), Yamagata Prefecture (山形県), and its surroundings from midday onward. In the afternoon, experience the nature of Oe Town, where the clear waters of the Mogami River (最上川) meet the scenery of the surrounding hills, and stroll through the historic temples and shrines of the Atarazawa area and the parks along the Mogami River. In the evening, secure a spot around Tateyama Park (楯山公園) and enjoy the fantastical summer night where lanterns drifting on the water's surface overlap with the fireworks. August 15, the anniversary of the end of the war, is the day when lanterns are floated in memory of those who came before, and the scene created together with fireworks coloring the night sky has a quiet emotional power unique to this festival. A summer night spent as a family, listening to the sound of the Mogami River, watching the lanterns sway, and looking up at the fireworks overhead, will likely become a memory that stays with your children for a long time.
