The Nature of Japanese Rule
- Japan established a military government across occupied territories, claiming to free Asia from Western imperialism through the Greater East Asia Co-Prosperity Sphere.
- In reality, Japan imposed authoritarian control, strict censorship, and economic exploitation to serve its war needs.
- Colonial structures were replaced by Japanese military administrators, who often ruled harshly and relied on fear, forced labor, and food requisition.
- Japan mobilized local elites and nationalist leaders, promising independence to gain cooperation, though power remained with the Japanese army.
- Propaganda stressed Pan-Asian unity, but racial hierarchies and brutality contradicted Japan’s liberation rhetoric.
Greater East Asia Co-Prosperity Sphere
- Japan’s imperial vision of economic and political unity in Asia under its leadership, often used to justify conquest.

Burma under Japanese Occupation (1942–1945)
Nature of Rule
- Japan invaded Burma in 1942, promising liberation from British rule and forming the Burmese Independence Army (BIA) led by Aung San.
- Initially, Japan allowed a puppet government under Ba Maw (1943), proclaiming Burmese independence but maintaining Japanese military control.
- Economic exploitation was severe: rice and oil were requisitioned for Japan’s war effort, leading to famine and inflation.
- Burmese civilians faced forced labor on projects such as the Burma–Thailand Railway, which caused thousands of deaths.
Impact
- By 1944, resentment grew as the Japanese occupation became increasingly brutal and exploitative.
- Aung San and other nationalists switched sides in March 1945, joining the Allied-supported Anti-Fascist People’s Freedom League (AFPFL).
- Japan’s fall left Burma with armed nationalists and an emerging leadership, paving the way for independence in 1948.
- The occupation fostered both national unity and militarization, shaping Burma’s postwar politics.
