We not only have zones, but we layer on historic districts, parking minimums, setbacks, etc., going further than just not mixing commercial and residential. We mandate certain lifestyles in a pretty big way. A big shock vs. living in Japan where one can choose very different lifestyles.
I also miss the freedom Japanese architects seemed to have, where a building shaped like a treehouse would be just one of several interesting buildings.
