That's why some Japanese people have 10 tv's and bright led's all over their vehicles. They are compensating for their small pizzas.

see as much as I love the idea of spending a few years in japan, I couldnt do it purely because of food portions.
im 6'2 235 lbs and am very active, and have to eat alot to keep my energy up. I think I would starve to death in japan, or elsewise wind up ordering 7-14 meals just for myself at restaurants there.
