Is that why Japan's elderly are all homeless?

Japan has an over-abundance of housing.

That's interesting given that land is very scarce in Japan. Suddenly, they decided to all squeeze together, make it clean and also be patient with one another. Something tells me this is about societal culture more than anything else.

Given the declining population predicted by OP, US housing stock will also grow in abundance by the time young people hit retirement age.
