Yes, Japan could well be a very different country in the not too distant future. I think the figures are also skewed by the amount of people who still live with their parents. A setup that allows them to live on their part-time/temporary pay without the burden of rent or a mortgage. Such options aren’t going to last forever though, and what happens when they cease to? Then like you say, there’s the skipping of health insurance, no hope of savings/pension etc. Things could be very rough for an awful lot of people.
