Fireworks festival is held on Sakurabuchi of Toyokawa, which is flowing through the city on the evening of August 13 every year, one of the summer traditions of Shinshiro City, the Nagasaki fireworks festival.

The number of fireworks to be launched is about 2,000. Because of the terrain interposed between mountains and mountains, explosive sounds of fireworks can resonate and you can enjoy powerful sounds that can not be heard elsewhere. In addition, the appearance of the silver waterfall flowing down from the 150 m wire stretched across Toyokawa is one of the highlights of the fireworks display with breathtaking beauty.
