The first national census based on a full sampling of inhabitants was conducted in Japan in 1920 and was conducted every five years thereafter. Per the Statistics Bureau of the Ministry of Internal Affairs and Communications, the population distribution of Japan proper from 1920 to 1945 is as follows

Date	Population	% Change	Area	Density	% Urban
1920-10-01	55,963,053	NA	381,808.04	147	18.0
1925-10-01	59,736,822	6.7	381,810.06	156	21.6

1940-10-01	73,114,308	5.6	382,545.42	191	37.7
1945-11-01	71,998,104	-0.7	377,298.15	195	22.8

The above figures include Hokkaidō, the northernmost island, sparsely populated, with area similar to the state of Maine; the central island of Honshū, larger than Ohio and Indiana, site of the most important cities and industrial centers; and smaller islands of Kyūshū and Shikoku, and Okinawa.
