When you say Japan imports more than it exports, for who? Corporations? Because major Japanese corporations export, Toyota, Honda, Sony, Nintendo etc. We're talking about favorable conditions for corporations here.

Personally, I didn't say the government is "intentionally" weakening the yen, but when the yen is weak, the people who "matter", don't complain or try improve the situation because it's good for exports. If the biggest companies in Japan are happy, I'm sure those who keep them happy are well looked after too.

If you care about a poor old lady in her house, you wouldn't want to see the price of everything go up.
