The Japanese occupation of Burma was the period between 1942 and 1945 during World War II, when Burma was occupied by the Empire of Japan. The Japanese had assisted formation of the Burma Independence Army, and trained the Thirty Comrades, who were the founders of the modern Armed Forces (Tatmadaw). The Burmese hoped to gain support of the Japanese in expelling the British, so that Burma could become independent.
In 1942, Japan invaded Burma and, on 1 August 1943, nominally declared the colony independent as the State of Burma. A pro-Japanese government led by Ba Maw was installed. However, many Burmese began to believe the Japanese had no intention of giving them real independence.
