The 29th Imabari Citizens' Festival Onmaku Fireworks Colorful fireworks color the night sky
The 'Onmaku' fireworks close Imabari's citizen festival on 9 August — roughly 10,000 shells in five acts fired along Imabari Port's long breakwater, a display billed as one of the largest in the Chugoku-Shikoku region. The name is local dialect for 'loads and loads', and the climactic run of 100 oversized shells honours it. Last year's crowd: 240,000. The show runs 20:00–20:55.
The long breakwater shapes the whole event: choreography spreads horizontally across the harbour's mouth, music-synced launches punctuate the acts, and viewing space follows the causeway for a kilometre-scale front row. This is a big, loud, properly local festival finale. JR Imabari Station is 15 minutes on foot. Parking is paid and reservation-based, so confirm arrangements on the official site; with 240,000 attendees, arrive 1.5–2 hours early for a front-facing spot and expect dense walkways both coming and going.
