Please stop extrapolating your anecdotal personal experience. Japanese people are eccentric (at least relatively to the rest of the world cultures); and anyone living there will have to consider that nuance when dealing with them.

That being said, your odds of getting into trouble in Japan are close to nil. It's a quiet safe and friendly environment.

My experience with Japanese people have been largely positive. But again, you have to take their eccentricity into a large context to reconcile their behavior with your expectations.
