Stacked zoning exists in the US and was very common in the wave of local zoning adoptions in the 1920's. Over time, other forms have tended to replace it or be selected for initial ordinances. I suspect Japan's history of zoning like many of it's political institutions arose under rather different circumstances in the 1940's, hence it is national law rather than local.
Anyway, I qualified "residential" with "prohibited".
