Buying beer in Japan is easier then here in the states for me. I am over 40 and still get carded here. Granted I look much yonger then I am, its funny to get carded by people who where not even born when I was legal to drink. When they give me lip I always say "when 48 you are look as good you will not" while pointing at my latest eye candy girlfriend
But in Japan no one gives a second though to my age.
