I'm almost definite that japan invaded Burma from Jan 15 to May 15 1942. They gained a lot by doing that.
Japan's expansion began in 1931. In the year, Japanese troops took over Manchuria in northeastern China. Six years later, Japanese armies swept into the heartland of China. They expected quick victory. Chinese resistance, however, caused the war to drag on. This caused a strain on Japan's economy. To increase their resources, Japanese leaders looked toward the rich European colonies of Southeast Asia.
