Japan’s expansion in the lead-up to World War II was driven by a complex mix of nationalism, militarism, and economic pressures. The rise of militarist factions within the government, combined with a deep-rooted belief in Japan’s destiny as Asia’s dominant power, set the stage for aggressive expansion into Manchuria and China. Tensions with Western powers, economic struggles, and the increasing influence of the military shaped Japan’s foreign policy, ultimately leading to its involvement in World War II.
