Around 3,000 fireworks, including set pieces and Niagara-style cascades, rise between 19:15 and 20:45, following lantern boats and floating lanterns on the water. Roughly 70,000 people attend each year; Nagatoro Station on the Chichibu Railway is a five-minute walk away.
Nagatoro Funadama Festival Fireworks take place around the Nagatoro Iwadatami riverbank on August 15, 2026, with about 3,000 shells fired in a 90-minute program from 19:15.
