I based my opinion on the apparent lack of return policies in Japan. On the few occasions I wanted to return merchandise here, I've found that the stores don't carry such policies. In the US, you'd be hard pressed to find a store that doesn't have some kind of policy for returns.
That as well as the problems many of my other foreign friends have had with settling problems over their cell phone bills and things like that. It just seems like Japan puts a good face forward, but what happens behind the scenes is not so satisfying. But, I'm sure this isn't the care everywhere in Japan... are there many stores that actually carry nice things like return policies? If so, please enlighten me.
