That's true for Tokyo and some big cities, but not true in the rest of Japan, which is very much built around cars with crumbling public transport.
As for food - lots of fried stuff in Kyushu everywhere you go. I'm thinking it must be the metabolism rather than the diet. However, yes, food portions are small by default. You have to ask "omori" to get the bigger one, and there are even bigger sizes offered sometimes!
