I guess if you look hard enough you'll find something, but otherwise you'll just be stuck in a crappy loop...
I have met kids as you describe, but so far they have been a minority of the younger Japanese (under 15) I have met. What surprises me is that such kids would come at me and say strange things in the street (or make comments about "gaijin"to their friends/parents assuming I can't understand what they say).
