Around here you pretty much NEVER see anyone wearing sunglasses unless it`s a fashion queen trying to look like a "celebitch" (An actual word they use to refer to themselves...) You don`t even see people wear them while driving - only the occasional truck drivers.

No one will actually think you`re a gangster, but they are sort of associated with that... Just like tattoos. No one will mistake you for something you aren`t, but the image still carries the connections and will not give a good impression. You might be able to get away with it in Tokyo or Osaka, but I know that around here it`s definitely not a common thing.

Oh, and an update on the polarized outlets. I actually took a look, and all the outlets in my house are polarized and about 1/3rd of them have the third prong.
