> I would rather pay 15% more on goods and 30% less on rent. Exactly. Housing and the housing market in Japan is an interesting beast. Based on my limited understanding as someone who has sort-of briefly looked at buying a home in Japan, houses are not really financial investments. For example, compare house prices in Japan (including the land) with a house in Australia.
Indeed, Japanese houses are designed to be disposable. Likely a result of them being built historically out of wood and paper and the abundance of wood.
The difference is partly the attitude towards houses, but it also has to do with how difficult it is for foreign investors to speculate in the market, the ubiquity of public transit (which makes accessibility as a value-driving feature mostly moot), the way the building code precludes a "missing middle" (or "missing cheap place"), and other features of modern Japanese society that are alien to Americans (and Canadians, but weirdly not always to Britons).
The point is that there are lots of ways to chip away at the affordability issue. It's just that ALL of them necessarily attack RE investors' ability to exploit their property to the fullest extent possible.
One last anecdote: South Korea is similarly situated to Japan, but is also facing an extreme affordability crisis. So, there is the suggestion that NONE of the material aspects matter if the owner class is determined to wring every cent out of you. The changes disincentivize gouging, but in the end, you just have to have property owners willing to acknowledge housing as a an affordable necessity and not a profit center built on the backs of a captive audience...
