As I said 2 weeks ago, the odds that you will bump into a festival when you come to Japan in summer are quite high. One of them is fireworks shows. There are fireworks shows in almost every town in Japan over the summer holiday period between June and August. Wanna play fireworks yourself instead of watching? Unlike many other countries, it is legal to play with fireworks in Japan. It also explains why you will see shops put out loads of fireworks products in this time.
