Why are Japanese fireworks beautiful?
The foremost feature of Japanese fireworks is that they form a beautiful circular shape. With a booming sound, petals of sparks radially spread from the center. This is because Japanese fireworks are designed with circles, whereas many others are in column shape. The beautiful circle of fireworks is created by regularly arranging gunpowder balls called “stars” inside a sphere.
Leisure fireworks started in the early 17th century in Japan. Like other countries, Japanese fireworks started with column shapes, but it is said that spherical fireworks techniques were developed in the late 19th century. This production method has influenced various evolutions to Japanese fireworks; for example, it made it possible to make fireworks in complex shapes, such as the shape of Saturn or a heart, through the arrangement of gunpowder balls. These developments of gunpowder formulas also added unusual colors such as lemon yellow or marine blue to the fireworks.
The recent significant evolution in fireworks is the technique to change colors. That enables the colors change in the middle of explosion, or show the color again after disappearance. Fireworks enthusiasts go to fireworks displays expecting to see new shapes and colors each year.

Fireworks have a short lifespan of about five seconds from the time they are fired until they disappear into the sky. Pyro technicians spend several months producing fireworks just for this moment. Let’s see the firework production process of Niigata Pyrotechnics Corporation, one of the leading fireworks studios in Japan.
1. Blending gunpowder
An oxidizing agent and chemicals are added to the gunpowder. The color of the firework is determined by the composition of these substances.
2. Making “stars”
The blended gunpowder is dissolved with water and starch, and made into a liquid. Then, this gunpowder liquid is poured over a core material such as a rapeseed in a rotating pot and drying it to form a layer. After repeating this process, it becomes gunpowder balls called stars. One piece of a star makes one petal of a firework. A star is an important element that determines the appearance of the firework, and it requires a high level of skill to make stars that are uniform in size.
3. Packing gunpowder
Dried stars are arranged in a semi-globular paper bowls, to which fuses are attached, and the gunpowder is packed into the inside of the starts for detonating the bowls in the air. Two semi-globular bowls are combined to make one ball.
4. Reinforcing firework balls
Reinforcing balls packed with gunpowder with craft paper.
The firework balls are complete after the gunpowder balls are thoroughly dried in the dry room.
6. Installing the cylinders for firing the fireworks
The cylinders for firing fireworks and the shooting devices are installed in specified positions. This process is carried out carefully because the fireworks may not fire as planned or an accident may occur if there is a mistake during this process.
