Reiwa 8 Iruma Base Summer Festival ~ Evening of Bon Odori and Fireworks ~ - Highlights include star mines and No. 4 shells
The Iruma Air Base Summer Festival opens the usually closed JASDF base in Sayama, Saitama Prefecture, on July 22, 2026, with bon-odori dancing, a taiko drum opening at 17:30 and about 900 fireworks between 20:20 and 20:50. Base stalls sell beer, ramune, seafood grills and yakisoba, and three pedestrian gates connect to Seibu Railway stations on foot.
A rare chance to step inside an active air base: the grounds open to the public for an evening of bon dancing and fireworks, drawing about 42,000 visitors. The taiko drums open the program at 17:30 before the 30-minute fireworks finale. Enter through the Inariyama gate (10-minute walk from Inariyama-koen Station), the main gate (15 minutes) or the temporary gate (13 minutes), both from Iruma-shi Station — there is no parking, so come by train. With several gates, fix your meeting point by gate name, and bring cash for the stalls.
