Japanese rule (1910–1945) Japanese rule (1910–1945) encompassed imperial expansion by Empire of Japan across East Asia, Northeast China, and the Pacific Ocean following the Russo-Japanese War and the First Sino-Japanese War. The period included formal annexations, colonial administrations, industrial projects, cultural policies, resistance movements, and wartime mobilization culminating in defeat after the Pacific War and the Soviet–Japanese War (1945).

Background and Annexation (Pre-1910 and 1910)

In the aftermath of the First Sino-Japanese War and the Treaty of Shimonoseki, the Meiji Restoration-era Imperial Japanese Army and Imperial Japanese Navy projected power that continued through victories in the Russo-Japanese War and diplomatic outcomes at the Treaty of Portsmouth. The annexation of Korea followed intervention during the Donghak Peasant Revolution and influences from the Kapsin Coup era, leading to the Japan–Korea Treaty of 1910 and establishment of the Government-General of Korea. Concurrently, the Treaty of Shimonoseki ceded Taiwan to Japan, prompting the creation of the Taiwan Governor-General and integration into the Empire of Japan colonial system.

Colonial Administration and Governance

Administration relied on institutions such as the Governor-General of Korea and Governor-General of Taiwan, supported by the Ministry of Home Affairs (Japan) and the Imperial Household Agency for legitimacy. In Manchuria, the Kwantung Army's influence and the creation of the State of Manchukuo involved figures like Zhang Xueliang indirectly, while diplomats in the Ministry of Foreign Affairs (Japan) negotiated ambiguous sovereignty after the Mukden Incident. Colonial police apparatuses included the Special Higher Police and the Kenpeitai, and legal frameworks drew on the Meiji Constitution and ordinances issued by Prime Minister cabinets such as those of Ito Hirobumi and Terauchi Masatake.

Economic Policies and Infrastructure Development

Economic integration featured investments by conglomerates like the Mitsui, Mitsubishi, Sumitomo, and Nippon Steel Corporation-linked entities, with projects such as the Chōsen Railway and the South Manchuria Railway Company underpinning resource extraction from Korea and Manchuria. Agricultural reforms targeted cash-crop production in Taiwan and Korea while industrialization fostered factories in Keijo and Dairen; financiers from the Zaibatsu coordinated with the Bank of Japan and the Ministry of Commerce and Industry (Japan). Infrastructure works included ports like Keelung, rail networks, and hydroelectric schemes exemplified by the Soyang Dam-era predecessors and projects influenced by engineers associated with the Imperial Japanese Army logistical corps.

Cultural Assimilation and Education

Cultural policy emphasized assimilation through systems modeled on institutions such as the Ministry of Education (Japan), including curricula promoting State Shinto rites, use of Japanese language in schools, and the deployment of officials from the Home Ministry and Bureau of Cultural Affairs. In Taiwan and Korea language and identity policies intersected with institutions like the Joseon Sinsaeng-era schools transformed under the Tokyo Imperial University pedagogical influence. Efforts to naturalize elites involved honors such as the Order of the Rising Sun and administrative co-option of local elites, while media control extended via newspapers aligned with conglomerates and censorship from the Police Bureau and House of Peers-era political norms.

Resistance, Nationalism, and Independence Movements

Resistance ranged from armed rebellions invoking leaders like Ahn Jung-geun and networks connected to the Korean Provisional Government to intellectual movements influenced by exiles in Shanghai, Wuhan, and Moscow. In Taiwan, indigenous uprisings intersected with activists linked to the Formosan Association for Public Affairs-era predecessors and figures such as Lin Hsien-tang advocating political rights. Organized parties and movements included the Korean Independence Movement, anti-colonial fighters collaborating with the Soviet Union and the Chinese Communist Party during the Second Sino-Japanese War, and organizations that drew upon international law debates at forums like the Paris Peace Conference precedents.

Wartime Mobilization and Military Control (1937–1945)

After the Marco Polo Bridge Incident and the escalation into the Second Sino-Japanese War, civilian administration increasingly yielded to the Imperial General Headquarters and military organs such as the Kwantung Army and the Southern Expeditionary Army Group. Mobilization involved conscription overseen by the Ministry of War (Japan) and labor drafts administered through offices linked to the South Manchuria Railway Company and ministries coordinating with the Greater East Asia Co-Prosperity Sphere doctrine promoted by propagandists like Kuniaki Koiso and Hideki Tojo. Occupation policies included military governors, internment practices administered by the Kenpeitai, and exploitation of resources during campaigns including the Battle of Shanghai and the Philippine Campaign (1941–1942).

End of Rule and Postwar Legacy (1945)

The collapse followed defeats at Midway, Leyte Gulf, and the Okinawa Campaign, the atomic bombings of Hiroshima and Nagasaki, and the Soviet invasion of Manchuria, culminating in Instrument of Surrender (1945) and Allied occupation under Supreme Commander for the Allied Powers. Postwar processes engaged the International Military Tribunal for the Far East and repatriation efforts managed by the Allied Council for Japan, while decolonization led to independence for Philippines, restitution to Republic of China (1912–1949), and the emergence of Republic of Korea and the Republic of China (Taiwan) as postwar states. Legacies endure in territorial arrangements involving Kuril Islands disputes, legal precedents from the San Francisco Peace Treaty, economic continuities linked to former Zaibatsu successors, and historical memory shaped by institutions such as universities and museums across Seoul, Taipei, Tokyo, and Beijing.
