Japan had such a system in the building-line system that was abolished in 1950. That system worked reasonably effectively to structure new development in the areas where it was applied in the 1930s, although it suffered from a crucial weakness compared to its German model in that in Japan all roads above the minimum width were considered building lines, and not just those created by municipal design. That loophole allowed building on many narrow existing lanes, and the situation only got worse after 1950 when even that weak regulation of urban development on the fringe was removed.
