1. Economic Needs: Japan was facing severe economic challenges due to the global Great Depression. Manchuria was seen as a resource-rich region that could provide access to raw materials like coal, iron, and timber, crucial for Japan's industrial growth.
2. Nationalism and Expansionism: Japan was motivated by a desire to expand its territory and strengthen its position as a major power in Asia. Manchuria was considered within Japan's sphere of influence, and some Japanese military and political leaders believed it was necessary to secure it to ensure Japan's security and prosperity.
3. Geopolitical Concerns: Japan was concerned about the growing influence of the Soviet Union in Manchuria and East Asia. They saw Manchuria as a strategic buffer zone to protect their interests in Korea and prevent Soviet expansion into the region.
4. Military Power and Prestige: The Japanese military sought to assert its strength and gain prestige by demonstrating its ability to successfully carry out military campaigns. Manchuria was seen as a relatively weak target, and the invasion provided an opportunity for the military to showcase its prowess.
5. Domestic Politics: The invasion of Manchuria also served as a diversionary tactic to divert attention away from internal political challenges and economic difficulties in Japan. It helped to rally public support around a common goal and consolidate the power of the military within the government.
