Watching a Japanese fireworks festival, it’s natural to wonder: how much does one of those cost? The answer is more interesting than you’d think.
Price depends on the shell size
Shell size is measured in go. A small 3-go shell (about 9 cm across) costs a few thousand yen; a shakudama (10-go) shell (about 30 cm) jumps to tens of thousands of yen. The bigger the shell, the more powder and the more painstaking the work — and the wider it blooms.
Why they’re expensive: handmade
Most Japanese shells are still made by hand — mixing the powder, forming the tiny ‘stars’, drying them, and packing them into the shell with millimetre precision. A large shell can take months to build. The price isn’t just materials; it’s a craftsman’s labour.
Launching costs extra
Buying a shell isn’t the same as launching it. You need licensed pyrotechnicians, permits, setup, and a check for unexploded shells afterward — so launching even one shell privately costs several times the shell price. At big festivals, security alone can run into the tens of millions of yen.
Prices are general estimates and vary by maker and year.
