The Okazaki Castle Ieyasu Summer Festival Fireworks is one of the most spectacular summer events in central Japan, held in Okazaki City, Aichi—the birthplace of Tokugawa Ieyasu, one of the most influential figures in Japanese history.

Set along the banks of the Oto River and Yahagi River, this iconic fireworks festival combines centuries-old Mikawa fireworks traditions with breathtaking modern pyrotechnics. Reflected on the river’s surface and framed by the historic castle town, the display creates an unforgettable Japanese summer experience that attracts visitors from across Japan and around the world.

Experience Traditional Japanese Fireworks in the Birthplace of Tokugawa Ieyasu

Located in the heart of Okazaki, the festival takes place near Okazaki Castle, where Tokugawa Ieyasu was born in 1543. The historic surroundings provide a unique backdrop that blends Japanese heritage with one of the country’s most celebrated summer traditions.

The event showcases the renowned craftsmanship of the Mikawa region, famous for its long history of fireworks production. Visitors can enjoy a variety of impressive displays, including dramatic starmine, traditional handcrafted fireworks, and elaborate synchronized performances that light up the night sky.

Before the fireworks begin, guests can stroll through the historic castle area, sample local street food, and experience the lively atmosphere of a traditional Japanese summer festival. As darkness falls, thousands of fireworks illuminate the riverside, creating a stunning scene that is both culturally rich and visually spectacular.
