Key facts and dates

The rise of militarism in Japan during the 1920s and early 1930s marked a significant shift in politics and society, as the military gained increasing control over governance and foreign affairs. This period saw the erosion of democratic structures and a surge in political violence, paving the way for aggressive expansionist policies.

Timeline of key events

• 1930 – Assassination of Prime Minister Hamaguchi by a nationalist extremist.
• 1932 – Assassination of Prime Minister Inukai by naval officers, escalating political violence.
• 1936 – February 26 Incident, an attempted coup by young army officers, highlighting military unrest.
• Early 1930s – Military dominates foreign policy, driving expansion in Manchuria and beyond.

The constitutional position and independence of the Japanese military

During the 1920s and early 1930s, the Japanese military held a unique and powerful position within the political system, which allowed it to operate with significant autonomy. This independence was rooted in the structure of the Meiji Constitution and set the stage for the rise of militarism.

Foundations of military independence

• Meiji Constitution (1889) - This constitution granted the armed forces a special status, placing them directly under the emperor's command rather than civilian government control. This meant the military was not accountable to elected officials or political parties.
• Right of direct access to the emperor - Known as iaku joso, this privilege allowed military leaders to bypass the cabinet and advise the emperor directly on matters of national security and military policy. As a result, civilian leaders had little influence over military decisions.
• Impact on governance - The separation from civilian oversight enabled the army and navy to pursue their own agendas, often disregarding the wishes of elected politicians and contributing to a growing divide between military and civilian authority.

The role of young officers' movements and secret societies in political violence

The 1920s and 1930s saw an increase in radical activism within the military, driven by young officers and secret patriotic societies. Their actions, often violent, challenged the established political order and accelerated the shift towards militarism.

Key groups and ideologies

• Kodoha (Imperial Way Faction) - A faction within the army that advocated for a return to traditional Japanese values, direct imperial rule, and aggressive expansionism. They believed in purifying the nation by eliminating corrupt politicians and capitalists.
• Toseiha (Control Faction) - A rival army faction that supported a more pragmatic approach, focusing on modernising the military and centralising control. Though less ideologically extreme, they still prioritised military dominance over civilian rule.
• Secret patriotic societies - Organisations like the Black Dragon Society, which promoted pan-Asianism and expansion, and the Cherry Blossom Society, composed of young officers plotting against the government, fuelled nationalist and militarist sentiments.

Incidents of political violence

• Assassination of Prime Minister Hamaguchi (1930) - Hamaguchi was shot by a nationalist extremist opposed to his policies of fiscal restraint and naval disarmament, reflecting growing hostility towards moderate leaders.
• Assassination of Prime Minister Inukai (1932) - Inukai was killed by naval officers during a failed coup attempt, driven by frustration with government corruption and perceived weakness in foreign policy. This event marked a turning point, as it intimidated civilian leaders.
• February 26 Incident (1936) - A group of young army officers attempted a coup in Tokyo, assassinating several government officials and occupying key buildings. Though the coup failed and leaders were executed, it revealed the extent of military unrest and the power of junior officers.

Doctrine of gekokujo

Gekokujo, translated as "rule by juniors", was a concept that justified direct action by lower-ranking officers to influence or override decisions by their superiors or civilian leaders, based on the belief that they were acting in the emperor's true interests. This doctrine emboldened junior officers to undertake assassinations and coups, undermining hierarchical control and contributing to political instability as their actions often went unpunished or were tacitly supported by senior military figures.

The military's dominance in foreign policy decision-making

As the military's influence grew, it increasingly took control of Japan's foreign policy, often acting independently of civilian government. This shift had profound implications for Japan's international relations during the early 1930s.

How the military shaped foreign policy

• Autonomous decision-making - With direct access to the emperor and little civilian oversight, military leaders initiated actions like the invasion of Manchuria in 1931 without cabinet approval, presenting the government with faits accomplis.
• Focus on expansionism - The military prioritised territorial expansion to secure resources and strategic dominance in Asia, driven by nationalist ideologies and the perceived need to counter Western imperialism.
• Weak civilian opposition - Political leaders, fearing assassination or public backlash, often acquiesced to military demands, allowing the army and navy to dictate aggressive policies that led to conflicts with China and tensions with Western powers.

The spread of militaristic values through Japanese society

Militarism was not confined to politics or the armed forces; it permeated Japanese society through various channels. This cultural shift reinforced the military's influence and prepared the population for war.

Mechanisms of militaristic influence

• Education system - Schools taught loyalty to the emperor, reverence for the military, and the virtues of sacrifice and discipline. Textbooks glorified Japan's martial history and promoted nationalist pride.
• Conscription policies - Universal military service, mandatory for young men, instilled military values across the population, creating a sense of shared duty and normalising the armed forces' role in everyday life.
• Cultural norms and propaganda - State-sponsored media and cultural narratives celebrated soldiers as national heroes, while festivals and public ceremonies often featured military displays, embedding militarism in social consciousness.

The weaknesses of political parties and the failure of Taisho democracy

The rise of militarism was facilitated by the fragility of Japan's early democratic experiments. During the Taisho period (1912-1926), often referred to as Taisho democracy, political parties struggled to establish lasting control over governance, creating a vacuum that the military filled.

Challenges facing Taisho democracy

• Weak political parties - Parties lacked deep-rooted support and were often seen as corrupt or self-serving, failing to inspire public confidence or counter military influence effectively.
• Limited democratic structures - Although the Taisho era saw greater political participation and universal male suffrage by 1925, the emperor's supreme authority and the military's constitutional position undermined democratic accountability.
• Failure to constrain military ambitions - Civilian governments could not enforce control over the armed forces, especially as military leaders exploited public disillusionment with politicians to justify their interventions in governance.
• Rise of nationalist sentiment - Economic struggles and perceived humiliations in international treaties fuelled public support for militarist solutions over democratic compromise, further weakening the political parties' position.
