+ Tokyo!
(all maps at the same scale)
What's crazy is Tokyo manages to pack the population of London and Paris combined in the same space without having to resort to super
high densities. The densest urban district of Tokyo, Toshima, has a population density of only 22,008 inh. per km² (57,001 ppsm), whereas
Paris's 11th arrondissement has a population density of 42,236 inh. per km² (109,391 ppsm), and in fact the entire City of Paris inside the
Périphérique (excluding the Bois de Boulogne and Bois de Vincennes) has a population density of 25,757 inh. per km² (66,711 ppsm), higher
than the densest district of Tokyo.
