Chubu · NiigataFireworks
A small Niigata town launches the world’s biggest firework, a metre-wide shell that blooms nearly 800 metres across the night sky.
Overview
The Katakai Fireworks, part of the Asahara Shrine autumn festival in the Katakai district of Ojiya, Niigata, is famous for launching the world’s largest firework: the yonshakudama, a shell over a metre in diameter that bursts into a flower roughly 800 metres wide. As a dedication to the shrine funded by the community, the display is intimate yet astonishing, set against a mountain backdrop. It ranks among Echigo’s three great fireworks festivals.
When & Where
The festival is held over two nights each September; in 2026 it falls on 11 and 12 September. Dedication fireworks light the evening of the 11th, and the grand finale on the 12th features the record-setting yonshakudama alongside thousands of other shells. It takes place in the Katakai district of Ojiya City, near Asahara Shrine. Nearest hub: Ojiya Station, with local shuttle or taxi access to the launch area.
Getting There
Ojiya is reached via Nagaoka on the Joetsu Shinkansen, transferring to the JR Joetsu Line for Ojiya Station; from there, seasonal shuttle buses or taxis run toward Katakai. Public transport is limited and roads are busy on festival nights, so plan your return in advance and allow plenty of time. Nights in the hills can be cool, so bring a layer.
What to Expect
The atmosphere is community-driven: many shells are dedicated by local families and businesses, announced before they launch. The climax is the yonshakudama, whose deep concussion you feel as much as hear, followed by an enormous, slowly falling flower of light. Expect food stalls, a shrine-festival mood and a strong sense of local pride.
Tickets & Access
Some viewing is possible from public areas, while paid reserved seating is typically offered and recommended given the crowds; check the official tourism information for the current arrangements and booking. Bring cash for stalls, a mat for seating, and pack out your rubbish.
Tips for Visitors
Reserve seating early and arrive well before dark to settle in. Stay for the 12th if you can, as that is when the record-breaking shell is launched. Combine with Ojiya’s famous nishikigoi (koi carp) culture and nearby hot springs.
