Yorii Tamayodo Suitengu Festival Fireworks Festival - Fireworks launched from the ruins of Hachigata Castle, one of Japan's Top 100 Castles
The Yorii Tamayodo Suitengu Festival fireworks light up the Tamayodo riverbed in Yorii Town, Saitama, on August 1, 2026, with about 5,000 shells over two hours from 19:00. The show accompanies a rite known as 'Kanto's greatest water festival', a tradition dating to 1931. Star-mines and set pieces spread across the night sky for some 65,000 visitors. Yorii Station, served by JR, Tobu and Chichibu Railway lines, is a 15-minute walk from the south exit — trains are the easy way in.
Held on August 1, 2026 on the Tamayodo riverbed — a prefectural-designated scenic spot — the show runs 19:00 to 21:00 with around 5,000 shells including star-mines and set pieces. Yorii Station's south exit (JR, Tobu, Chichibu Railway) is a 15-minute walk away. No parking is provided at the venue; the site is about 15 minutes by car from the Hanazono IC via Route 140, but traffic controls operate around the venue on the day, so rail is the safer bet. Stalls line the riverbed for the festival, paid seats are available, and a leisure sheet helps on the stony, sandy ground.
