The confirmed fireworks launch dates for this festival are listed below.
Atami's sea-launch fireworks continue their winter calendar with three dates spanning December 6, 2026 to February 21, 2027, each firing about 3,000 shells over Atami Bay from 8:20 p.m. Roughly 8,000 people per night watch bursts born on the water. Free viewing runs along the bay, food stalls operate on show nights, and no parking is arranged — the onsen resort town walks to its fireworks.
Atami, the classic hot-spring resort on the Izu coast, is one of the few places in Japan where fireworks are a year-round institution, and the 2026-27 winter calendar keeps the tradition running: three dates between December 6, 2026 and February 21, 2027, each with roughly 3,000 shells launched from the bay — from the port's 7.5-meter quay line to the fishing facility — starting 8:20 p.m. Winter's dry, clear air is the season's argument: color hangs crisp over the water for the roughly 8,000 spectators per evening. Viewing is free along the bayfront; food stalls operate on show nights; no event parking is arranged, in keeping with a resort town built around its station. The Atami tourism association confirms dates through the season — pair a show with an onsen ryokan stay.
