tout passe, tout casse, tout lasse

Why would the Japanese abandon their traditional style of housing? Without even watching the video, I can conjecture that population pressure meant building upwards (building downward in earthquake territory would have been folly, not to mention expensive), which would mean modern apartments, not old-style wooden houses, to allow for stacked residences (I hesitate to call them communities since neighbors in these places barely know each other). But the video mentions a host of other reasons, too, varying from sociocultural to practical.
