Yea, there are some easily defined planned residential neighborhoods in Japan - but honestly there are very few of them, especially compared to the US where there is pretty strict zoning in the suburbs - vs no zoning whatsoever in suburban/rural Japan.
I really like adding the landuses sub-block by sub-block, and in many cases plot to plot, because the imagery was good enough to do it.
it is also a ton easier than drawing all the houses - as the houses in Japan are 1/2 size and crammed very close to one another, so tracing them is very tedious.
Getting the basic landuses + parks in between the residential roads really adds detail to the map with little effort.
