The States has Airsoft IPSC community. And we all know how easy it is to get a gun there.
And don't forget in 2004 a kid from Japan won the IPSC world championship. Now handguns are illegal in Japan so he trained with airsoft and a month or real firearms shooting before the competition. [I'll try to find the actual article later]
There seems to be enough interest. There's no reason we can't start an airsoft IPSC event ourselves over here.
