I think housing is a bad example to use wrt Japan.
Japan is one of the few markets in the world where, for the most part, only land has value. Buildings LOSE value over time. This is for multiple reasons but mostly due to ever-changing earthquake-related construction regulations such that it's almost always cheaper to rebuild from scratch than keep an edifice and retrofit to regulations.
This is also why Japan has more architects than any other country- if buildings are not kept and are almost always destroyed after a 30 year mortgage, the owner can build whatever they want and not have to be concerned about resale value- so lots of unique residential architecture.
Alastair Townsend first covered this in ArchDaily years ago and it went on to be covered extensively by NPR and other outlets.
