Lanterns the size of a tatami matline the river for a kilometre.
The Furutone River Lantern Festival (古利根川流灯まつり) is Sugito's summer event, held every early August. About 250 handmade lanterns, each roughly the size of a tatami mat, float on the water for about 1 km along the river's bends. The tourism association calls it "the Milky Way come down to earth", and in 2026 it was held for the 31st time.
