^^ internal flights are under a$150.. by comparison, the shinkansen from tokyo to nagano is about a$120. so niseko is not much more expensive. http://www.jal.co.jp/yokosojapan/

also, hakuba is just as full of drunk aussies as niseko. if you want to avoid the cultural cringe the best thing you can do is to make sure you don't stay in a place that looks like it'll attract aussies... then you'll be mostly ok.

ps. it's not hard to find a half-decent selection of cereal in japan.. taking weetbix is pretty funny
