Usa's Port Festival closes its two-day run — September 19 and 20, 2026 — with about 5,500 shells fired off the north breakwater of Nagasu Fishing Port in Oita, launches from 8:00 p.m. Roughly 5,000 spectators gather along the harbor. The organizer is the Awashima Shrine activity group, a reminder of how shrine tradition and port festivity intertwine; food stalls, paid seating, and parking complete the working-harbor setting.
On the northern coast of Oita, the port town of Usa gives its autumn festival a maritime finale: across two evenings, September 19 and 20, 2026, roughly 5,500 shells launch from the north breakwater of Nagasu Fishing Port, starting at 8:00 p.m. The organizing Awashima Shrine activity group gives the night a festival pedigree that pure tourism events lack, and the crowd of around 5,000 spreads along the quay where paid seating secures the best sightlines and food stalls keep the harbor festive. Parking is available for drivers. The two-date format is forgiving — if weather spoils one evening, the other remains. Festival-day details circulate mainly through the committee's Instagram account, so check it before traveling. The 8:00 p.m. start keeps both evenings relaxed after dinner.
