The invasions of Manchuria in 1931 and China in 1937 by Japan represent a crucial juncture in 20th-century Asian history. These aggressions triggered profound shifts in international alliances and set the stage for the Pacific Theatre of World War II.
The Manchurian Incident (1931)
Prelude to Invasion
- Japan's victory in the Russo-Japanese War (1904-1905) had already given it a foothold in Manchuria.
- The global economic downturn post-1929 affected Japan's export-dependent economy, increasing the impetus for territorial expansion.
The Mukden Incident
- Japanese military personnel sabotaged the South Manchuria Railway, attributing the act to Chinese dissidents.
- Used as a pretext for the invasion, asserting the need to protect Japanese interests.
Occupation and Control
- Manchuria was swiftly overtaken by the Kwantung Army, showcasing Japan's military prowess.
- Strategic cities and railways were secured within months, establishing de facto control over the region.
Manchukuo and International Legitimacy
- Japan's puppet state, Manchukuo, was an attempt to legitimise its control.
- However, the move was largely unrecognised, with the notable exception of Nazi Germany and Fascist Italy.
The Lytton Report
- The League of Nations dispatched the Lytton Commission to investigate, culminating in the Lytton Report which condemned Japan's actions.
- Japan's subsequent exit from the League marked its international isolation.
The China Incident (1937)
Marco Polo Bridge Incident
- A minor skirmish at the Marco Polo Bridge near Beijing escalated into full-blown warfare.
- Japan leveraged the incident to launch a comprehensive invasion of China.
Tactics and Expansion
- By the end of 1938, Japan controlled major coastal cities and the Chinese heartland.
- The 'Three Alls Policy' (kill all, loot all, burn all) was indicative of Japan's scorched earth strategy.
Nanjing Massacre
- In December 1937, Japanese forces captured Nanjing, resulting in mass atrocities against civilians and prisoners of war.
- The massacre severely tainted Japan's international image and fuelled anti-Japanese sentiment globally.
Western Diplomatic and Economic Reactions
Gradual Escalation of US Sanctions
- Initial US sanctions were limited to moral embargoes, such as the 1938 "Moral Embargo" which opposed the sale of aircraft to Japan.
- The embargo expanded to include a wide array of materials critical to Japan's war and industrial efforts.
Impact of the Embargoes
- Japan's reliance on imports for essential resources made the embargoes particularly debilitating.
- The restrictions exacerbated Japan's resource scarcity, intensifying the need for securing resource-rich territories.
The Tripartite Pact (1940)
Strategic Alliance Formation
- Seeking to consolidate power and deter American intervention, Japan formalised alliances with Germany and Italy.
- The pact was a defensive agreement, promising mutual assistance if one of the signatories was attacked by a power not already involved in the war (e.g., the United States).
Implications for the United States
- The Tripartite Pact was a direct challenge to US influence and deterrence in the Pacific.
- It effectively ended any remnants of diplomacy between the US and Japan.
Japan's Military Governance
The Role of the Army in Politics
- The success in Manchuria emboldened the military faction within the government, leading to an increase in its influence over political and economic policy.
- Military leaders often bypassed or coerced civilian government, effectively steering national policy.
Political Turmoil and Assassinations
- The 1930s saw political assassinations and attempted coups, such as the February 26 Incident, reflecting the volatile domestic political climate.
- Militarists sought to purge political opponents and steer Japan towards totalitarianism.
Socio-Economic Changes
Mobilisation and Propaganda
- The government mobilised the nation for total war, including intensive propaganda campaigns to justify invasions.
- Propaganda extolled the virtues of the Japanese spirit and the destiny to lead Asia against Western colonialism.
Economic Strain and Prioritisation
- The wartime economy prioritised military needs over civilian, leading to rationing and controls.
- Industrial production was reoriented towards the war effort, affecting everyday life in Japan.
Pre-War Tensions and the Path to Pearl Harbor
Japan's Strategic Calculations
- The cumulative effect of embargoes, particularly the oil embargo, was a critical factor in Japan's decision to attack Pearl Harbor.
- Japan sought to neutralise the US Pacific Fleet to secure its ambitions in Southeast Asia and the Pacific.
Final Diplomatic Efforts
- In the months leading up to Pearl Harbor, Japan engaged in diplomatic negotiations with the US, which ultimately proved fruitless.
- The Hull Note, delivered in November 1941, demanded Japan's withdrawal from China and Indochina, which Japan considered an ultimatum.
Legacy and Consequences
The Foundation for the Pacific War
- The invasions of Manchuria and China laid the groundwork for Japan's broader ambitions in the Pacific.
- These events directly influenced the strategic planning and alliances that would come to fruition during World War II.
Reflections on International Law and Order
- Japan's defiance of international norms reflected the limitations of international organisations like the League of Nations.
- The period underscored the need for a more effective international system, which would later influence the formation of the United Nations.
The invasions by Japan into Manchuria and China not only reshaped the Asian continent but also had profound implications for global geopolitics. They precipitated a series of events that led to the wider conflict of the Second World War, and their legacy is reflected in the post-war international order. Understanding these invasions is critical for comprehending Japan's role in world history during the first half of the 20th century.
FAQ
Post-World War I economic conditions in Japan, characterised by recession and resource scarcity, were critical in shaping its aggressive foreign policy. The Great Depression had a devastating impact on Japan's economy, exacerbating unemployment and falling prices, which led to social unrest. In response, Japan pursued a policy of territorial expansion to secure natural resources, markets for its goods, and space for its growing population. The invasion of resource-rich Manchuria was partly motivated by these economic imperatives, as Japan sought to establish a self-sufficient empire insulated from global economic fluctuations.
The Marco Polo Bridge Incident was motivated by Japan's desire to further consolidate its power in China and to quell the growing resistance of Chinese forces. On the night of July 7, 1937, a skirmish between Japanese and Chinese troops near the bridge served as the pretext for Japan's full-scale invasion of China. The incident was escalated by the Japanese military as part of a broader strategy to initiate a war that would allow Japan to impose its rule over China and establish dominance in East Asia. The scale of the ensuing conflict far exceeded the initial clash, leading to widespread warfare across China.
The successful invasions of Manchuria and China bolstered the military's prestige in Japan, leading to an increase in their influence over government and society. Militarists gained substantial control over national policies, sidelining the civilian government and promoting a nationalistic, expansionist agenda. The invasions also precipitated a series of political assassinations and attempted coups, as militarists sought to eliminate political opposition. This led to the consolidation of a military regime that prioritised imperialist ambitions and facilitated the rise of totalitarianism in Japan, with Emperor Hirohito being increasingly relegated to a ceremonial role.
The US embargo, especially the 1940 embargo on oil and steel, had significant economic impacts on Japan's war effort in China. The embargo deprived Japan of essential materials needed for its military and industrial machinery. Without access to these resources, Japan's ability to sustain its military operations in China was severely compromised. The Japanese military faced shortages of fuel, which hindered its naval and air capabilities, and the industrial sector struggled to maintain production levels. This scarcity accelerated Japan's decision to seek new territories rich in resources, such as Southeast Asia, and ultimately led to the attack on Pearl Harbor as a pre-emptive move to secure its expansionist aims.
Pan-Asianism played a significant role in Japan's foreign policy and provided a philosophical justification for its invasions of Manchuria and China. This ideology promoted the idea of Asian unity against Western imperialism and portrayed Japan as the leader of an Asian bloc. It was used domestically to foster support for Japanese expansion by presenting it as a crusade for the liberation and unification of Asia under Japanese guidance. However, in practice, Japan's version of Pan-Asianism was marked by a hierarchical view that placed Japan at the centre, often resulting in exploitative and oppressive treatment of other Asian peoples.
Practice Questions
The Japanese invasion of Manchuria in 1931 severely undermined the credibility of the League of Nations. The League's failure to take effective action against Japan for its aggression revealed the weaknesses of international diplomacy at the time. Despite the Lytton Report which condemned Japan's actions, the League's lack of enforcement mechanisms and the absence of key world powers, like the United States, limited its ability to respond effectively. This emboldened Japan to leave the League, highlighting the impotence of the League in maintaining peace and foreshadowing the international community's slide toward World War II.
Japan signed the Tripartite Pact in 1940 to consolidate its position as a dominant power in East Asia and to deter American intervention while it expanded its territory. By forming an alliance with Germany and Italy, Japan sought to secure its conquests and further its ambitions without interference. The Pact provided Japan with a sense of security, given the mutual assistance agreement against any attacking power, notably the United States. It also indicated Japan's commitment to the Axis powers' ideology, aligning itself against the Allied powers and setting the stage for its role in World War II.
