Actually, I don't think it's a case of where you live. I think it's a case of where you lived before.
I'm assuming from your avatar that you're American. What you don't usually appreciate is that in America, practically everything is cheaper than most other developed countries. You've had it better than everyone else for years, and when you leave your own country you suddenly find out what it's like to live in the rest of the world. If you'd come from somewhere like the UK, you wouldn't find Japanese pricing particularly unusual. In fact in many respects it's often cheaper.
You act as though it's by random undeserved chance that things are cheaper in the US. But really US prices are a strong argument against cartels, protectionism, controlled economies, and lack of competition. These are areas the US is strong in, thankfully, which is why prices are cheaper in the US.
But *sigh*, I'll be prepared to pay out the wazoo in Japan.
