Largest cities in Japan by population by decade

This article lists the ten most populous cities in Japan by decade, starting after the Meiji Restoration of 1868. The first Japanese Census was not conducted until 1920, but other civilian and military population counts were carried out in the prior years between 1872 and 1918, and those form the source data for this article. When data is not available right on the turn of the decade, the closest year is used.

1873

edit

In 1868, the Meiji Restoration deposed the Tokugawa Shogunate and founded the Empire of Japan. Many major cities had lost population since the Tokugawa Era, as samurai left the former castle towns after the collapse of the military order.

Source data is from "Nihon Chishi Teiyo" (日本地誌提要, the Japanese Topographical Outline).

1 1 Tokyo Tokyo 595,905 Formerly known as Edo, whose population is estimated to be over a million under the Tokugawa, but after the Meiji Restoration, roughly half the city's population emigrated. Nevertheless, Tokyo retained its position as Japan's largest city, which it had held since the mid 17th century.

1881

edit

Several major cities and towns actually lost population over the 1870s, as people continued to emigrate out of the former castle towns.

Source data is from the Fourth Joint Military-Government Report (第四回共武政表), a requisitioning document listing municipal populations and available resources and provisions.

1891

edit

In 1888, the government enacted a sweeping overhaul of the municipal government system, part of which involved a drastic program of municipality mergers. Overall, the "Great Meiji Mergers" cut the number of municipalities in Japan by more than three quarters, while dramatically increasing the size of many cities as they absorbed their surrounding towns and villages.

1950

edit

Japan emerged from the Second World War in defeat, under temporary American administration. Many cities had been attacked by American bomber forces, and many of the largest cities suffered further loss as residents evacuated to more rural regions of the country. Cities, though, were already recovering quickly from their wartime lows.

1960

edit

A series of municipal mergers throughout the 1950s known as the "Great Showa Mergers" cut the number of municipalities in Japan by almost two thirds, significantly increasing the size of many cities in the process. By this time, almost all of Japan's largest cities had recovered war losses and exceeded their prewar populations.

In the mid-2000s, another series of municipal mergers was enacted. The "Great Heisei Mergers" nearly halved the number of municipalities in Japan, once again increasing the size of some cities significantly and creating new towns and cities. Despite a mounting population loss in rural areas and some smaller cities, Japan's major cities continue to grow.
