About
This early-summer festival takes place at Yasumiya on the shore of Lake Towada, a caldera lake in Towada-Hachimantai National Park. It had been held 60 times, but rising costs and staff shortages led organizers to consider calling it off. For 2026, ninety years after the area became a national park, organizers condensed the usual two days into a single day. By day, food stalls and kitchen cars line a lantern-lit fair area while performers take the stage. After dark, balloon lanterns float over the water, personal message fireworks are launched, and a fireworks display lights up the lake as the finale; a night cruise lets you watch it all from the water. There are no bins on site, so plan to take your trash home.
