“Tokyo is one of the few cities in which supply has kept up with demand, keeping a crisis from developing. But that is due largely to deregulated housing policies that other countries would have a hard time reproducing.”
This “crisis” is completely artificial and the solution is obvious: take off the zoning straight jacket and make it legal to build higher density housing.
Property owners should have zero authority over anything outside of their property lines. Giving Joe Blow the ability to shout down and bikeshed new developments is idiotic.
