The 3rd Yonezawa Sengoku Fireworks brings warring-states-era spectacle to the Yonezawa Municipal Baseball Stadium on October 10, 2026, from 6:30 p.m. — about 8,000 shells themed on the sengoku age, before an audience of roughly 15,000. The stadium format means ticketed, organized seating plus food stalls and on-site parking: closer to a produced arena show than a riverbank free-for-all, and already a fixture in just its third year.
Sengoku — Japan's warring-states age — supplies the staging for Yonezawa's young fireworks event, now in its third year on October 10, 2026. The venue is the municipal baseball stadium: a contained arena where roughly 8,000 shells launch from 6:30 p.m. for about 15,000 spectators, with themed production leaning into the city's warlord history. Contained means ticketed — paid seating sold in tiers — plus food stalls in the concourse zones and stadium parking for arrivals. October in the Yonezawa basin is already deep autumn; the organizers plan for cold-night viewing, and so should you. Ticket sales and program details run through the event's official site (sengokuhanabi.com), which also posts the themed program notes that give the night its narrative.
