Japanese Ambitions in Southeast Asia Before 1941

Japan aimed to establish a Greater East Asia Co-Prosperity Sphere under its domination, encompassing:

• Economic control of resource-rich areas (oil, rubber, tin).
• Military control of strategic points (bases, straits).
• Political control over conquered territories.

This imperial vision drove expansion into Manchuria (1931), China (1937), and ultimately Southeast Asia after 1941.
