I live in Japan and it's a virtual paradise for all the reasons you mention. However, unfortunately my parents are lardgoblins, and them coming to visit me is the height of humiliation, as they nearly have panic attacks at the sight of every staircase and it takes them every ton of effort to squeeze into a chair. Fuck, my mother almost didn't fit into a booth. A fucking booth! It's embarrassing enough in the US where they are sadly a very commonplace form factor, but I refuse to take them to places in Japan that I know or like, or where someone I know might see me with them. Just shameful...
