80th Atsugi Ayu Festival - Powerful fireworks show coloring the night sky on the first day of the festival
The fireworks night that opens Atsugi's Ayu (sweetfish) Festival in Kanagawa—a two-day, October 10–11, 2026 celebration with the launch show on the Saturday. From the confluence of three rivers on the Sagami, roughly 10,000 shells rise in what the city bills as one of Kanagawa's largest displays. Star mines anchor the program, and the finale's 'Great Niagara' pours a cascade of light down toward the river surface.
The riverbed at the three-river confluence is about a 15-minute walk from Hon-Atsugi's east exit (and walkable from Ebina as well). Around it, the festival runs citizen-powered programming—parades, dance contests—across two days expecting over half a million visitors in total. The festival honors the ayu, the sweetfish that has long defined the river town's identity. Launch positions sit close to the viewing banks, so this is one for visitors who want physical impact over panorama. No event parking exists; the train is the plan. The festival's second day shifts to parades and dance contests, so out-of-town visitors usually target Saturday for the fireworks and Sunday for the daytime mood. Stations stay crowded long after the finale, so keep schedules loose, and let the October river wind carry the Niagara's reflection home in memory.
