Weird that this guy has lived in Japan for ten years, but he groups a bunch of culture aspects in with his evidence of poverty. Preparing a lunch box, recycling bath water for laundry, using kerosene heaters? These are just how things are done in Japan, no matter how much money you have. Maybe that's one of the cultural differences this author is missing. Most people in Japan, even when they are far more wealthy than their neighbors, still live exactly the same lifestyle.
