Magical Nagatoro Funatama Festival with lanterns floating on the river

About this spot

Held on August 15, 2026, from 5:10 PM to 8:45 PM along the Arakawa River near Iwatatami. This traditional memorial service honors those lost to water and prays for river safety. As darkness falls, countless lanterns float on the river, creating a mystical band of light in the darkness unique to Nagatoro, surrounded by mountains and river. This long-standing local tradition combines quiet prayer with the cool summer night air along the riverside.

Tips

Riverside lighting becomes limited after dark; bring a flashlight or use your smartphone light. Temperature drops at night, so wear a light jacket. Large crowds are expected; keep children close by hand.

Best time to visit

From 5:10 PM start. After sunset, when lanterns float on the river (around 6:30 PM onward), the most mystical atmosphere is created.
