Japan’s fairly simple urban zoning scheme seems to work quite well. There’s essentially a sliding scale from light residential to heavy industrial, but “lighter” uses are always allowed in “heavier” zones.

> but “lighter” uses are always allowed in “heavier” zones. As far as I know, this is true of the American zoning system, as well.

  In the US you can usually build "lighter" within a category, up to a point, but not across categories (e.g. you could build a single family home in a high density residential zone, but not in a commercial zone). I'm not sure how that compares to Japan's system, but from GP's comment it sounds like you can cross categories there.

    It depends on your local law. Where I live, we have mixed use, office residential, general office and warehousing. All broadly allow home building of various types. Going the other way, the rules are quite detailed as to what sort of commercial operations you could start from a residential property in those zones, subject to superseding HoA restrictions.

    Japan’s system is more about what would disrupt QoL around it. If you want to open a small bakery in the middle of a residential neighborhood you can do so. Not really economically viable, but some people run these things out of just the front room of their house.

      Why wouldn't it be economically viable ? It's been done like this for centuries in France.

        Most people buy around the stations. It’s not theoretically impossible, I just don’t get the idea that these places are exceptionally profitable.

  It’s not. US zoning often strictly regulates usage.

  This is almost never true in practice in the US.

  One of the major differences with the American system is that the Japanese government only has twelve types of zones that local governments are allowed to use. https://urbankchoze.blogspot.com/2014/04/japanese-zoning.html https://urbankchoze.blogspot.com/2014/04/japanese-zoning.htm... American zoning codes get really complicated really fast, particularly around what businesses are considered low-nuisance in what neighborhood. Especially the moment people start getting worried about parking. Particularly home businesses, like daycare, hair salons, even the humble lemonade stand can all be zoned down to a single hair.
