You know, like I mentioned before, I think with the sunglasses (especially at night) no one dares stare at me, even in Akita (except some of the kids, but then the parents look kinda nervous). I think it's because (1) it makes me a doubly-intimidating gaijin (cuz, you know, already semi-gojira-sized), and (2) they can't tell if I'm looking back, so nobody does more than glance quickly and look away.
I guess I look like a loony rock star or something. I'd much rather look at least slightly approachable, but しょうがない。
I think it really freaks out people when I bow at them, though. I don't think any of these older サラリーマン were expecting that.
