Final answer:
Japan expanded during the 1930s to secure resources, establish their own empire, and combat perceived threats.
Step-by-step explanation:
Japan expanded during the 1930s for several reasons:
- The Japanese Empire sought to secure access to resources such as oil, which were key to their military power and overall industrial growth.
- They wanted to liberate Asia from European colonialism and establish their own empire in Eastern Asia.
- Japanese militarists viewed the rise of Communism in the Soviet Union and China as a threat and found ideological common ground with Fascism and National Socialism.
These factors led to Japan's aggressive expansionism in the 1930s, which ultimately contributed to the outbreak of World War II.
