Asahi City Iioka YOU-Yu Festival 2026 Coastal Fireworks Festival - The star mines blooming in the night sky are simply breathtaking
On the open sands of Iioka Beach in Asahi, Chiba, roughly 5,000 shells—centered on mid-size 2.5 to 4-go rounds—launch close enough to feel. The beach is famous as the model for the drama 'Fireworks, Should We See It from the Side or the Bottom?', a connection the festival's own site embraces. Beyond the October 3 evening show, the day brings bazaars, stage performances and night stalls from around noon. All parking is paid, advance-reservation only.
From Sobu-line Iioka Station, the city's community bus runs about 10 minutes to Hagisono, a 5-minute walk from the beach; drivers coming via the Sosa IC need about 30 minutes but will hit event-day road closures. The beach itself, selected among Japan's 100 Great Shorelines, is closed to vehicles—every legitimate parking space is paid, advance-reservation only, with sales opening in early September and nothing sold on the day, and no free lots at all. The festival grounds open around midday with bazaars until 15:00, then fireworks from 19:15 to 20:00 before crowds that historically approach 98,000. Stormy weather cancels, with no reserve date. From the sand, the low viewing angle makes even mid-size shells feel enormous—most spectators spread a ground sheet rather than chairs, since sightlines sit nearly level with the launches, and the night stalls behind the beach handle dinner.
