one of the largest empires in history. The total amount of land under Japanese sovereignty reached in 1942.
By 1943, it accounted for more than 20% of the world's population at the time with 463 million people in its occupied regions and territories.

After Japan was defeated by the Allies in 1945, the colonial control over the far-flung territories from Tokyo ended. The extent of Japanese governance was restricted to the ''naichi'' (excepting Karafuto Prefecture, which was
annexed by the Soviet Union); the
Nanpō and
Ryūkyū Islands were returned to Japan in 1968 and 1972 respectively.

''. But this effort was less an initial step toward colonial expansion than it was a reassertion of national authority over territories traditionally within the Japanese cultural sphere.
Acquisition of colonies
At the start of the twentieth century the rate of population increase in Japan was seen as a potential problem for the Japanese government, and colonial expansion into Korea and Manchuria was seen as a possible solution.
Taiwan
Between 1895 and 1945,
Taiwan, including the
Pescadores, was a
colony of the
Empire of Japan; following the defeat of
Qing China

in the
First Sino-Japanese War, it ceded Taiwan to Japan under the terms of the
Treaty of Shimonoseki. The short-lived
Republic of Formosa resistance movement was quickly suppressed by the Japanese military. The
fall of Tainan ended organized resistance to Japanese occupation and inaugurated five decades of Japanese rule.
Since Taiwan was Japan's first overseas colony, the central and colonial governments turned their efforts into making the island a "model colony". These resulted in the modernization of the island's economy, infrastructure, industry, public works, and
assimilation of its population.
In 1945, after the defeat of the
Empire of Japan in
World War II, Taiwan was placed under the control of the

Korea
In the late 19th and early 20th centuries, various Western countries competed for influence, trade, and territory in
East Asia, and Japan sought to join these modern colonial powers. The newly modernized
Meiji government of Japan turned to Korea, then in the
sphere of influence of China's
Qing dynasty. The Japanese government initially sought to separate Korea from Qing and make Korea a
Japanese satellite to further their security and national interests.
In January 1876, Japan employed
gunboat diplomacy to pressure
Korea, under the
Joseon Dynasty, to sign the
Japan–Korea Treaty of 1876, which granted
extraterritorial rights to Japanese citizens and opened three Korean ports to Japanese trade. The rights granted to Japan under this
unequal treaty,

Commodore Perry.
Japanese involvement in Korea increased during the 1890s, a period of political upheaval.
Korea was occupied and declared a Japanese
protectorate following the
Japan–Korea Treaty of 1905; it was annexed in 1910 through the
annexation treaty.

. Following the
Meiji Restoration in 1868, Japanese settlers were sent to southern Sakhalin to exploit its resources. Japan ceded southern Sakhalin to Russia in 1875 in exchange for the Kuril Islands under the
Treaty of Saint Petersburg. After achieving victory in the
Russo-Japanese War, Japan was ceded southern Sakhalin under the terms of the
Treaty of Portsmouth. Japan established its colonial government in 1907, whereupon South Sakhalin was renamed
Karafuto Prefecture.
Japanese and Korean migrants to the colony developed the fishing, forestry and mining industries. Taking advantage of the
Russian Civil War, the
Imperial Japanese Army occupied northern Sakhalin between 1920 and 1925; afterwards Japan retained favorable coal and oil concessions therein until 1944. In 1943, Karafuto was elevated to ''

in the
First Sino-Japanese War, Japan was ceded the southern part of the
Liaodong Peninsula under the terms of the
Treaty of Shimonoseki.
Diplomatic pressure from Russia, Germany, and France forced Japan to quickly relinquish the territory, which allowed Russia to lease it from China in 1898. In 1905, Russia was defeated in the
Russo-Japanese War; under the terms of the
Treaty of Portsmouth, Russia returned the Liaodong Peninsula to Japan, whereupon it was renamed the
Kwantung Leased Territory
The Kwantung Leased Territory ( ja, 關東州, ''Kantō-shū''; ) was a leased territory of the Empire of Japan in the Liaodong Peninsula from 1905 to 1945.

Japan temporarily occupied Outer Manchuria in 1918, but returned it to in
Soviet Union in 1922. Inner Manchuria came under the control of the Chinese warlord
Zhang Zuolin during the

was renamed Hsinking and became the capital of Manchukuo. An
imperial palace was specially built for the emperor. He was, however, nothing more than a figurehead and real authority rested in the hands of the Japanese military officials. The Manchu ministers all served as front-men for their Japanese vice-ministers, who made all decisions.
Anti-Japanese Volunteer Armies were organized by the Chinese in Manchuria and the
pacification of Manchukuo required a war lasting several years.
During the 1930s the Japanese colonized Manchukuo. With Japanese investment and rich natural resources, the

experienced rapid economic growth. Manchukuo's industrial system became one of the most advanced, making it one of the industrial powerhouses in the region. Manchukuo's steel production exceeded Japan's in the late 1930s. The Japanese Army initially sponsored a policy of forced industrialization modeled after the Five Year Plan in the Soviet Union
[Maiolo, Joseph ''Cry Havoc How the Arms Race Drove the World to War, 1931-1941'', New York: Basic Books, 2010 page 30] but subsequently private capital was used in a very strongly state-directed economy. There was progress in the area's social systems and many Manchurian cities were modernized. Manchukuo issued banknotes and postal stamps, and several independent banks were founded. The
Chinese Eastern Railway was bought from the Soviet Union In 1935. Traditional lands were taken and redistributed to Japanese farmers with local farmers relocated and forced into
collective farming units over smaller areas of land.
During this period Manchukuo was used as a base from which to invade China. In the summer of 1939, a border dispute between Manchukuo and the
Mongolian People's Republic resulted in the
Battle of Khalkhin Gol. During this battle, a combined
Soviet Army and Mongolian force defeated the Japanese
Kwantung Army (''

'') supported by limited Manchukuoan forces. The
Soviet Union declared war on Japan on 8 August 1945 under the agreement at the
Yalta Conference and invaded Manchukuo from outer Manchuria and Outer Mongolia. This was called
Manchurian Strategic Offensive Operation. The Army of Manchukuo was defeated and the Emperor was captured by Soviet forces. Most of the 1.5 million Japanese who had been left in Manchukuo at the end of World War II were sent back to their homeland in 1946-1948 by U.S. Navy ships in the operation now known as the
Japanese repatriation from Huludao.

Economic development
According to Atul Kohli, the David K.E. Bruce Professor of International Affairs and Professor of Politics and International Affairs at
Princeton, "the Japanese made extensive use of state power for their own economic development and then used the same state power to pry open and transform Korea in a relatively short period of time". Japan was "decisive in altering both the nature of the Korean state and the relationship of this state to various social classes." How the Japanese centralized bureaucratic style of government was transferred to Korea; how they developed Korean human capital by a considerable expansion of education; how the Japanese invested heavily in infrastructure. Kohli's conclusion is that "the highly cohesive and disciplining state that the Japanese helped to construct in colonial Korea turned out to be an efficacious economic actor. The state utilized its bureaucratic capacities to undertake numerous economic tasks: collecting more taxes, building infrastructure, and undertaking production directly. More important, this highly purposive state made increasing production one of its priorities and incorporated property-owning classes into production-oriented alliances". This sprawling bureaucratic state continued post-
World War II and after the
Korean War. Japan's early colonial industrialisation of Korea also made it easier to rebuild after the Korean War, because there was no need to begin industrialisation ''
ab initio''. Examining Korea's policies and achievements in the 1960s and 1970s, Kohli states that during this period the country was firmly heading towards "cohesive-capitalist development, mainly by re-creating an efficacious but brutal state that intervened extensively in the economy". South Korean economic development was not market-driven—rather the "state intervened heavily to promote exports, using both market and non-market tools to achieve its goals".
