The 79th Ibusuki Onsen Festival Fireworks fills Ibusuki Central Park in southern Kagoshima on September 27, 2026, launching about 4,000 shells from 7:30 p.m. Nearly eight decades of continuity make it a fixture of the onsen city's calendar. Admission is free, food stalls ring the park, and parking is arranged — with the hot-spring district a short walk away, the post-show soak is the traditional finale.
Ibusuki, at the subtropical southern end of Kagoshima, has run its onsen festival for 79 years, and the fireworks remain its public climax. On September 27, 2026, about 4,000 shells go up from 7:30 p.m. over Ibusuki Central Park, a short walk from the hot-spring district. The format is classically open: free admission, no paid seating, food stalls around the park perimeter, and festival parking. September evenings in southern Kyushu stay warm, so the post-show crowd drifts naturally into the onsen district rather than dispersing — plan a late bath and an overnight stay to do the festival properly. The executive committee's dedicated site (onsenmaturi.com) carries the year's schedule and any weather decisions. The 7:30 p.m. start suits the warm southern evening.
Seventy-nine years running: 4,000 shells over an onsen city at Kagoshima's subtropical edge.
