Approximately 20,000 fireworks bloom in the autumn night sky—Oyama's largest fireworks festival
About this spot
The Oyama Summer Festival (Oyama Fireworks) is one of the largest fireworks festivals in the Kanto region, held at the Omokawa riverside in Oyama City, Tochigi Prefecture, featuring approximately 20,000 fireworks. The fireworks launched from the wide riverbank have nothing obstructing them, and the spectacle of large blooms reaching high into the night sky is extraordinary. Viewing fireworks in the clear autumn air offers a dignified beauty distinct from summer festivals. The experience of watching from the riverside—with the band of light reflected in the river surface and the sound of fireworks resonating through your body—is a fitting climax to the day. The memory of sharing this moment with your family will surely remain in your hearts for a long time.
