Nagaoka Festival Grand Fireworks Festival — Enjoy a rare showcase of large fireworks hard to see elsewhere
The confirmed fireworks launch dates for this festival are listed below.
Nagaoka's grand fireworks rise over the Shinano River on both 2 and 3 August, from 19:20 to 21:25, in a display that carries the memory of the air raid that destroyed the city — a memorial for those lost, thanks to those who rebuilt, and a prayer for lasting peace. Viewing seats line both banks, a rare layout that lets oversized shells fill the entire river width.
Few fireworks events carry this weight of history. The two-night programme uses oversized shells freely across the broad river, and the twin-bank layout means every position looks directly at the launch — an experience particular to Nagaoka's geography. Around 340,000 visitors came across the two nights last year, so free-area space becomes competitive from early afternoon; expect crowded walkways and station gates. JR Nagaoka Station is a 30-minute walk from the venue. Parking exists but its arrangements change year to year — confirm on the official site, and if buying seats, do so in advance.
