I think the health of Japanese people is caused by:
1) One does a LOT more walking in Japan than in North America, due it not being a society based on cars. There is also almost nowhere to sit down in public, so people have to stand a lot too.
2) Food science isn't nearly as universal in Japan as in North America. Most food here is actual food, and not something cooked up in a lab. The strange exception to that is cheese - you cannot buy real cheese at a normal grocery store, just processed crap. Tons of Japanese food isn't health-food (ramen, katsu, karaage, korokke, etc), but it's not a pile of chemicals so it's not too bad for you either.
They don't have inherent genetic benefits, since iirc Asian-Americans actually have shorter lifespans than whites, and every Japanese exchange student I know (hundreds) gained a significant amount of weight when they went to Canada.
So in short, I don't think you need to knock yourself out trying to avoid carbs in Japan, since you're going to lose that weight just through normal Japanese-style life.
