The thing I find interesting is that in Japan, there is still plenty of access to unhealthy food. Street food vendors are everywhere- crepes, croquette, takoyaki, curry with fried pork cutlets, you name it. But quick, cheap, HEALTHY food is also easily available. Even the vending machines are mostly loaded with water, coffee, and unsweetened tea, with little options for sodas. It's so much easier to eat healthier over there even with a busy lifestyle, and therefore it's harder to make excuses if you end up getting fat.
