1920 Commemorative stamp for 1st national census of the Empire of Japan

The population of Japan at the time of the Meiji Restoration was estimated to be 34,985,000 on January 1, 1873, while the official original family registries (本籍, honseki) and de facto (or present registries (現住, genjū)) populations on the same day were 33,300,644 and 33,416,939, respectively. These were comparable to the population of the United Kingdom (31,000,000), France (38,000,000), Austria-Hungary (38,000,000), and the United States (38,558,371) in 1870.

Japan proper

Meiji government established the uniformed registered system of koseki (戸籍, family registries) in 1872, which is called Jinshin koseki (壬申戸籍).

The first national census based on 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 (km2)	Density (km2)	% 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
1930-10-01	64,450,005	7.9	382,264.91	169	24.0
1935-10-01	69,254,148	7.5	382,545.42	181	32.7
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 (except for the 1945 census values).

In Japan proper, the population of major cities was as follows:

In 1937 Japanese demographers projected the Japanese population in 1980 to reach 100,000,000, in accordance with observed growth rates.

Japanese overseas possessions

Japan annexed Taiwan after the First Sino-Japanese War, while victory in the Russo-Japanese War gained Japan the Kwantung Leased Territory, Karafuto, and Korea. These acquisitions increased the area controlled by Japanese to 262,912 square miles (680,939 km²).

Per the 1920 census, the total population of the Empire of Japan, including Taiwan, Korea and Karafuto was 77,005,112, which could be broken down as follows :

• Japan proper: 55,961,140
• Korea: 17,284,207
• Taiwan: 3,854,000
• Karafuto: 105,765

In 1925 the total population of Japan proper was 59,737,000; with Karafuto, Korea and Taiwan came to 83,458,000 subjects. In 1925 in the Kwantung Leased Territory, it was estimated that there were 91,000 Japanese (mostly military personnel and government workers) and 660,000 Chinese.

For the 1935 census for the whole Japanese empire, the figures are:

• Japan proper: 69,254,148 residents
• Korea: 22,899,038
• Taiwan: 5,212,426
• Karafuto: 331,943
• Kwantung: 1,656,726
• South Seas Mandate: 102,537

Total: 97,697,555 inhabitants

The estimated population in the exterior provinces in 1940 was:

• Korea: 24,327,326
• Formosa: 5,746,959
• Karafuto: 339,357
• Kwantung: 1,889,123 (of whom 309,029 were Japanese, and 2,185 other nationalities)
• South Seas Mandate: 121,128

Total: 105,226,101

Manchukuo

The population of Manchuria in early 1934 was estimated at 30,880,000. These numbers included 30,190,000 Chinese, 590,760 Japanese, and 98,431 other nationalities (Russians, Mongols, etc.). The Chinese numbers included 680,000 ethnic Koreans. In 1937, shortly after the foundation of Manchukuo, the government launched a twenty-year colonization program, with the goal of increasing the population through the immigration of 1,000,000 Japanese families (5 million people) between 1936 and 1956. This was in addition to the Japanese military garrison of approximately 300,000 men in 1937. Between 1938 and 1942 a contingent of young farmers of 200,000 arrived in Manchukuo; joining this group after 1936 were 20,000 complete families. In Shinkyo Japanese made up 25% of the population. By 1940, the total population of Manchukuo was estimated at 36,933,000, which included approximately 1 million Japanese civilian and 500,000 Japanese military personnel. These figures exclude that of the Kwantung Leased Territory and Dalien, which were included within that of the Japanese overseas territories.
