Bring a Japanese fireworks festival to your Minecraft night sky

Japanese Fireworks Festival is a command-driven datapack that recreates the motion, pacing, color transitions, and lingering trails of Japanese fireworks. It includes a fully sequenced grand show as well as an independent continuous mode for screenshots, videos, festivals, and multiplayer events.

Highlights

A 180-launch grand program lasting about 169 seconds
Ten launch tubes arranged in front and back rows for visual depth
Different burst heights selected for each firework and scene
A separate 103-launch continuous program that loops until stopped
Three particle-quality presets for groups of different sizes
Optional HUD-free filming mode
Custom positional launch, burst, distant echo, and taiko sounds
A grand 240-trail Shidare Yanagi finale

Japanese firework styles

Kiku (Chrysanthemum): spherical bursts with luminous trailing stars
Botan (Peony): clean moving stars without long trails
Nishiki Kamuro: long-lasting golden crown trails
Gin Kamuro: bright silver crown trails
Yashi (Palm): a small number of thick, branching trails
Tora-no-O (Tiger Tail): powerful trails rising from the launch tubes
Youraku: quiet fragments that drift slowly through the air
Hachi (Bee): small stars that move erratically across the sky
Rings, Saturn, UFO, heart, Creeper, and Zombie shaped fireworks
