They don’t just make fireworks here — they design them.
Inside a Japanese factory, an automatic Tamahariki machine wraps each firework shell with surgical precision, layering paper until the thickness is perfect.
That precision controls how the blast spreads and how the colors bloom — turning chemistry and timing into a flawless sphere of light.
Packed inside each shell are tiny “stars” made from metal compounds; when the core charge fires, they scatter and spell color across the sky.
Watch how centuries of craft meet modern engineering to design a single, breathtaking burst.
