2026 Nagatoro Funatama Festival: A Full Day Course
This one-day course centers on the Nagatoro Funatama Festival (長瀞船玉まつり), held from 17:10 on August 15, 2026, around the Iwadatami rock shelf (岩畳), a scenic spot in Chichibu. During the day, visit Hodosan Shrine (宝登山神社), enjoy the sweeping panorama from the summit via the ropeway, and walk through the Iwadatami landscape carved by the raging currents of the Arakawa River (荒川). In the evening, have an early dinner along Iwadatami-dori Street (岩畳通り) before the festival begins in earnest at 17:10, when lanterns are set afloat on the Arakawa River. It's a day the whole family can enjoy, filled with the mountains, the river, and the lights of a Nagatoro summer night.
