japan can get away with it because they have a societal code the far out weighs the US!! go up to most business after hours and the doors are unlocked. At least thats the way it was when I lived there for 3 1/2 years. the only down side is if they ever got invaded. Japan is an actual peaceful society. they dont have the garbage we do...
Common factor is other countries....Denmark, Sweden, etc....I hate to say it....but they don't have a certain demographic like we do.......Just Sayin. You know the didn do nufin crowd.
