mate, none of those things pose any particular problems, unless its obvious to the japanese person you are talking to that you are just trying to offend, annoy or that you're simply unaware of how devoid of any manners you are... take your pick
The Japanese are always nice to your face.
thats only if you don't pay attention / you're not subtle enough to understand the messages etc
Try changing a 1000 yen note a few times in different locations.
Try going to a "public" bath house.
Try going to the "country" like Niigata ken for skiing
Try working in any area other than teaching English
zero problem whatsoever, even when my japanese was still crap...
Try discussing Japanese atrocities like Unit 731 and mass slaughters in Korea
no problem, you'll be faced with total denial, thats all... what d'u want to tell us about the extermination of the aborigines in australia, equal rights etc?... am not comparing but just asking, out of curiosity
Try asking why they don't pay any attention to international conventions
like? the kyoto protocol? the non-proliferation treaty? the geneva conventions? be specific...
Try asking a businessman what "enjo kosai" is
you mean, with a big wink etc, ask a japanese businessman you've just met whether he likes to have paid sex with underage girls???

why don't u try asking an aussie businessman that, and then report back to the board, how many teeth you've got left
