Let's go to fireworks festival "Hanabi" in Japan.

Traditional Japanese fireworks are called rocket fireworks, launched as balls from a cylinder.
There are many points to observe, from the altitude of the blast to the alignment of the blast stars (powder that generates light and smoke of fireworks), the shape of the star, and the trails of smoke.
As with cherry blossom viewing, it is standard to bring a picnic sheet and relax on the grass while sharing a beer or meal with friends.
