This is only tangentially relevant. Japan has a culture where it's accepted that residential property is relatively medium term, and should be upgraded or rebuilt semi-regularily. Contrast that to real estate as an investment/heritance vehicule in the west.
Also, personnaly I wouldn't be ready to live in a Tokyo flat and I suspect most of the target population isn't either. That we may not have a choice down the line is likely, but another issue.

I think I'd live in a Tokyo flat if it cost $1200/month for a one-bedroom spot in the centre! [0] (with outstanding public transit, too)
For that price, you can get a bunk-bed in San Francisco [1]

This sounds like an excuse. The city of Tokyo alone builds more housing every year than the entire state of California: https://www.thenational.ae/business/property/want-affordable...
Tokyo is an in-demand city in an earthquake prone area, and they've managed to create enough housing to stay ahead of demand.
