I don’t know about Tokyo or what the options really are for raising kids in Japan. But I think (I’ll join you here with spewing opinion/ conjecture everywhere) in the US a lot of people intentionally leave cities once they decide to have kids. When you are a young professional in your 20s, it’s still very popular to live in dense urban centers, but then as you get married and start having kids, the vast majority of people move out to the suburbs or more rural areas. Now, obviously this is a privileged class of people, and maybe there are different trends in socioeconomic classes above and below them. And perhaps they move out of the city for other reasons (the price of housing, the quality of schools, etc), but I think access to nature also plays a part. But I say this as a girl scout troop leader, so I’m definitely biased.
