What this is
Okazaki is the historical birthplace of Mikawa fireworks — a regional pyrotechnic tradition stretching back centuries — and this annual summer display is where that heritage is most dramatically on show. Master pyrotechnicians fire shells ranging from 4-inch bursts on the Otogawa River up to massive 10-inch shells on the Yahagi River, with specialty effects including melody mines, picture fireworks, and goldfish-shaped displays. The 2026 edition marks both the 78th running of the festival and Okazaki City's 110th anniversary, giving it added ceremonial weight.
Who should go
Anyone with a serious interest in Japanese fireworks culture rather than just a casual summer outing — the Mikawa tradition is genuinely distinct and this is one of the best places in the country to see it performed at scale. Families, couples, and solo travellers all attend; the dual-river setup means crowds spread across two viewing areas.
Good to know
Free riverside viewing spots are available on a first-come basis, but paid reserved seating sections are typically sold through eplus.jp and pia.jp — both accept foreign credit cards, and convenience store pickup at Lawson is the most practical option for visitors without a Japanese delivery address. The event spans two rivers simultaneously, so it is worth deciding in advance which bank you want to watch from, as moving between them during the display is difficult once crowds are in place. Vendors selling food, drinks, and festival goods line the approach routes, but cash is strongly recommended as many stalls do not accept cards. The display typically runs for around 90 minutes. Note that the city listing places this under Nagoya, but the event takes place in Okazaki — plan your transport accordingly.
