Japan expanded her empire in the 1930s and 1940s to include parts of China and Southeast Asia

Explanation;
Japanese expansion in East Asia began in 1931 with the invasion of Manchuria and Shanghai in 1932, then continued in 1937 with a brutal attack on China. Other expansion were; Japanese expansion into Hopei in 1933, expansion into inner Mongolia in 1937.
In early 20th century Japans population rapidly increased to a point that in 1937 the population was 70 million people. The country could not sustain itself on its own because of the lack of arable land, which brought the need to expand into Manchuria (Northeast region of China).
