Urban Areas
Derived from 2002-2003 MODIS satellite data at 1 km resolution:

(below) Japan is one of the most populated countries. View from Kyoto to Tokyo.
Issues
New version of the MODIS-derived urban area grid is now available (announcement, data download) at 0.5 km and uses an improved algorithm for better accuracy:

No scale ranks. Missing just a couple polygons for points included in populated places.
Could be split apart (intersected with thiessen polygons derived from populated places points) and joined with populated places points to derive names and population values (and density).
