While true, I was mostly speaking of zoning. I consider things like gender norms as being cultural and not necessarily overlapping with their city zoning. From a pure urban design perspective, its basically perfect in my opinion. (That said, it's not entirely correct that culture and urban design are separate. I'm not sure Japanese cities can be recreated in America, if for no other reason than there is a huge gulf between how individuals view and interact with society in Japan vs. America)

It's also worth noting that while stressors from gender norms exist in Japan, the idea that their suicide rate is extremely high is somewhat outdated. Its been decreasing over the last few decades, while countries like the US and many European countries have increased, to the point where there isn't that much of a difference between the regions.
