Technology of shooting up
What is necessity for holding on good fireworks display?
Off cource,that is quality of each shells and combination of each other and whole story of display.
And one more, that is rhythm or tempo of launching. Rhythm means Japanese "Ma" and "Kankyu" in here. "Ma" is interval and pause. "Kankyu" is high and low speed or loose and tight of tempo. When talk to about Japanese traditional launching style cannot do without these both feelings.
This Olympic display, taking electronic firing system, making a sign of fire is analog style,too. That is push the fireing button all together to the sign of director. It's look like very old-fashioned at a glance, but this is consummated skill of Japanese traditional launching style. Put all launching rhythm into director's intuition and experience that cultivated many years. This is what Japanese launching technique.
We can safely say that pyrotechnist of Nagano are show both high quality japanese shells and performance of shootng up it on this Olympic project.
Five shooting up area at a long distance. It was impossible to connect fireing cable each spot. Could not centralized control to fire at one place, so firing sign through director's transceiver to each person in charge of firing.
Pyrotechnists have rehearsed the play many times for the work in perfect harmony. All 15 fireworks factory in Nagano meet together in a hall, such opportunities do not occur every day, never after this time. Normally, almost they not work with each other.
