Why drink Australian beer in Japan? (you can do that when you get back) -- might as well try Japanese beers while you're there. Where else can you purchase alcohol from vending machines?! Enjoy your time in Japan and just immerse yourself in the culture and language - for better or worse (every culture/society has its good and bad elements). Worry about experiencing Aussie things for when you're in Australia. When I was in Japan I made a conscious effort to distance myself from the English language and Anglo-culture and tried as much as possible to immerse myself in Japanese language and culture.
