Japan is doing great? Ha ha ha!!! They have been wrestling with an incredible banking crisis for years now, and more than a few analysts think the entire banking system could crash anytime. Basically, when a company is in debt and can't pay, the banks (for YEARS) would simply loan the company more money, compounding the problem. So, there are billions and billions of bad loans on the books that will never, ever be paid. They've made significant progress but aren't out of the woods yet.
Incidentally, foreign investment is starting to move into Japan, particularly US investment. They've only recently opened up their country to outside investment of any significance, bowing to pressure from the US and others to open their market.
