The home of Mikawa fireworks, this is one of the biggest displays in Aichi, with spots by the river reserved a day in advance by many. With a history dating back to the Edo period, the festival uses 70% locally produced fireworks. As a clan stronghold, Okazaki was one of the few towns allowed to produce gunpowder, lead by the Ono family. Spectators from across the prefecture and beyond gather for the event with food stalls, entertainment and music. The show lasts two hours and has some seriously impressive displays, so arrive early and grab a seat!
