Of all the examples to pick ;) that one's super wrong for Japan.
Unlike many other countries, Japanese houses aren't treated as an investment.
So they don't have widely unaffordable housing, unlike what's happening elsewhere.
There's a bunch of info about this online if you're interested. Random example here:

This is among the best ways to learn things: just say something and read people people explaining how that is wrong :-)
Nevertheless, let me mention a relevant fun fact: I even remember there was a research paper (or maybe a non-academic experiment somewhere on Reddit or so, I fail to recall for sure) which says postulating something wrong publicly is way more efficient than asking a question - much more people rush to emerge passionately addressing all the flaws of your opinion in details and with references than when you ask.
