The 14th Iyo Sai Festival Fireworks Festival Cannot take your eyes off the powerful extra-large star mine
The Iyo-sai Matsuri Fireworks close the summer festival held on the last Saturday and Sunday of July in Iyo City, Ehime, with the 2026 edition set for July 26 at the Iyo Port breakwaters. Around 10,000 fireworks fill the hour from 8:00 pm, and last year's edition drew about 100,000 spectators. Launches use two breakwaters spanning roughly 350 meters in total, and paid seating sits close to the launch sites. The signature pieces are the Kinryu-kyo Super Star Mine played over the sea and underwater fireworks that bloom some 120 meters across. Both Iyo City Station and Gun-chu Port Station are a 10-minute walk; free parking holds about 600 cars.
Because the launches come from two breakwaters that bracket the venue, bursts open across a wide front of the bay rather than from a single point, and the short distance between seats and launch sites puts sound and light right on top of you. The underwater fireworks — opening roughly 120 meters across — exploit the broad water surface in a way river venues cannot. Both JR Iyo City Station and the Iyo Tetsudo Gun-chu Port Station sit about 10 minutes away on foot. Free parking offers around 600 spaces but fills up, so the organizer recommends public transport. Note there are no food stalls on site, so bring what you need.
