Teradomari Port Festival Marine Fireworks Festival - A grand star mine blooming across both the sea surface and above the sea
Teradomari's Marine Grand Fireworks light up the Sea of Japan coast in Nagaoka, Niigata, on Friday, August 7, 2026, from 19:30 to 20:45 with 5,000 shells. Grand star-mines spread their light across both sea and sky — a flourish only an offshore launch can deliver — while spectators take in the show from the sand with the sea breeze in their faces. The 2025 edition drew 23,500 visitors. The venue offers 2,500 free parking spaces, and taxis run about 15 minutes from JR Teradomari Station.
Teradomari's summer show sends 5,000 shells up over the Sea of Japan in quick succession. Its grand star-mines stretch light across both the surface and the sky above — bold staging that only a launch site at sea allows — and the payoff holds your attention to the final shell. Viewing centers on the sands of Teradomari Port and the central swimming beach, where the classic move is spreading a straw mat and settling in with the salt wind. The venue provides 2,500 free parking spaces, but rail arrivals need taxis: about 15 minutes from JR Teradomari Station, 45 from JR Nagaoka Station. Taxi queues lengthen after the finale, so sort your ride home in advance.
