Origins and History of Okazaki Castle Town Ieyasu Summer Festival Fireworks Display

The event originated with the dedication fireworks held on the Oto River as part of Sugō Shrine’s festival, which dates back to the Edo period.

Records show that a fireworks display attended by the feudal lord was held in 1818, with fireworks launched by each town in the castle town.

The first Tourist Summer Festival Fireworks Display was held in 1948, after the war, and in 1958 the Sugō Festival joined the city-sponsored fireworks display, establishing the format that continues today.
