Japanese soldiers reading the Imperial Rescript to Soldiers and Sailors

Japanese militarism (日本軍國主義 or 日本軍国主義 Nihon gunkoku shugi?) refers to the ideology in the Empire of Japan that militarism should dominate the political and social life of the nation, and that the strength of the military is equal to the strength of a nation.

History of Japanese militarism[]

Rise of militarism[]

The military had a strong influence on Japanese society from the Meiji Restoration. Almost all leaders in Japanese society during the Meiji period (whether in the military, politics or business) were ex-samurai or descendants of samurai, and shared a set of values and outlooks. The early Meiji government viewed Japan as threatened by western imperialism, and one of the prime motivations for the Fukoku Kyohei policy was to strengthen Japan's economic and industrial foundations, so that a strong military could be built to defend Japan against outside powers.

Domestic issues within early Meiji Japan also called for a strong military. The early Meiji government was threatened by internal revolts, such as the Saga Rebellion and Satsuma Rebellion, and numerous rural peasant uprisings.

The rise of universal military conscription, introduced by Yamagata Aritomo in 1873, along with the proclamation of the Imperial Rescript to Soldiers and Sailors in 1882 enabled the military to indoctrinate thousands of men from various social backgrounds with military-patriotic values and the concept of unquestioning loyalty to the Emperor as the basis of the Japanese state (kokutai). Yamagata like many Japanese was strongly influenced by the recent striking success of Prussia in transforming itself from an agricultural state to a leading modern industrial and military power. He accepted Prussian political ideas, which favored military expansion abroad and authoritarian government at home. The Prussian model also devalued the notion of civilian control over the independent military, which meant that in Japan, as in Germany, the military could develop into a state within a state, thus exercising greater influence on politics in general.[1]

Following the German victory in the Franco-Prussian War, the Army Staff College and the Japanese General Staff paid close attention to Major Jakob Meckel's views on the superiority of the German military model over the French system as the reason for German victory. In response to a Japanese request, Prussian Chief of Staff Helmuth von Moltke sent Meckel to Japan to become an O-yatoi gaikokujin.[2] In Japan, Meckel worked closely with future Prime Ministers General Katsura Tarō and General Yamagata Aritomo, and with army strategist General Kawakami Soroku. Meckel made numerous recommendations which were implemented, including reorganization of the command structure of the army into divisions and regiments, thus increasing mobility, strengthening the army logistics and transportation structure with the major army bases connected by railways, establishing artillery and engineering regiments as independent commands, and revising the universal conscription system to abolish virtually all exceptions. A bust of Meckel was sited in front of the Japanese Army Staff College from 1909 through 1945.[3]

Although his period in Japan (1885–1888) was relatively short, Meckel had a tremendous impact on the development of the Japanese military. He is credited with having introduced Clausewitz's military theories[4] and the Prussian concept of war games (kriegspiel) in a process of refining tactics.[5] By training some sixty of the highest-ranking Japanese officers of the time in tactics, strategy and organization, he was able to replace the previous influences of the French advisors with his own philosophies. Meckel especially reinforced Hermann Roesler's ideal of subservience to the Emperor by teaching his pupils that Prussian military success was a consequence of the officer class's unswerving loyalty to their sovereign Emperor, as expressly codified in Articles XI-XIII of the Meiji Constitution.[6]

The rise of political parties in the late Meiji period was coupled with the rise of secret and semi-secret patriotic societies, such as the Genyōsha (1881) and Kokuryukai (1901), which coupled political activities with paramilitary activities and military intelligence, and supported expansionism overseas as a solution to Japan's domestic issues.

With a more aggressive foreign policy, and victory over China in the First Sino-Japanese War and over Russia in the Russo-Japanese War, Japan joined the imperialist powers. The need for a strong military to secure Japan's new overseas empire was strengthened by a sense that only through a strong military would Japan earn the respect of western nations, and thus revision of the unequal treaties.

Economic factors[]

During the 19th century, Great Power status was considered dependent on resource-rich colonial empires, both as a source of raw materials for military and industrial production, and international prestige.

Due to the lack of resources in Japanese home islands, raw materials such as iron, oil, and coal largely had to be imported. The success of Japan in securing Taiwan (1895) and Korea (1910) had brought Japan primarily agricultural colonies. In terms of resources, the Japanese military looked towards Manchuria's iron and coal, Indochina's rubber, and China's vast resources.

Independence of the military[]

Also forming part of the basis for the growth of militarism was the freedom from civilian control enjoyed by the Japanese armed forces. In 1878, the Imperial Japanese Army established the Imperial Japanese Army General Staff office, modeled after the Prussian General Staff. This office was independent of, and equal to (and later superior) to the Ministry of War of Japan in terms of authority. The Imperial Japanese Navy soon followed with the Imperial Japanese Navy General Staff. These General Staff offices were responsible for the planning and execution of military operations, and reported directly to the emperor. As the Chiefs of the General Staff were not cabinet ministers, they did not report to the Prime Minister of Japan, and were thus completely independent of any civilian oversight or control.

The Army and the Navy also had decisive say on the formation (and survival) of any civilian government. Since the law required that the posts of Army Minister and Navy Minister be filled by active duty officers nominated by their respective services, and since the law also required that a prime minister resign if he could not fill all of his cabinet posts, both the Army and the Navy had final say on the formation of a cabinet, and could bring down the cabinet at any time by withdrawing their minister and refusing to nominate a successor. In reality, while this tactic was used only one time (ironically to prevent a General, Kazushige Ugaki, from becoming Prime Minister in 1937), the threat always loomed high when the military made any demands on the civilian leadership.

Growth of ultranationalism[]

During the Taishō period, Japan saw a short period of democratic rule (the so-called "Taisho democracy"), and several diplomatic attempts were made to encourage peace, such as the Washington Naval Treaty and participation in the League of Nations. However, with the beginning of the Shōwa era, the apparent collapse of the world economic order with the Great Depression starting in 1929, coupled with the imposition of trade barriers by western nations and an increasing radicalism in Japanese politics including issues of domestic terrorist violence (including an assassination attempt on the emperor in 1932 and a number of attempted coups d'état by ultra-nationalist secret societies) led to a resurgence of so-called "jingoistic" patriotism, a weakening of democratic forces and a belief that the military could solve all threats both domestic and foreign. Patriotic education also strengthened the sense of a hakko ichiu, or a divine mission to unify Asia under Japanese rule.

Those who continued to resist the "military solution" including nationalists with unquestionable patriotism, such as generals Jotaro Watanabe and Tetsuzan Nagata and ex-Foreign Minister Kijūrō Shidehara were driven from office or an active role in the government.

A turning point came with the ratification of the London Naval Treaty of 1930. Prime Minister Osachi Hamaguchi and his Minseito party agreed to a treaty which would severely limit Japanese naval power. This treaty was strongly opposed by the military, who claimed that it would endanger national defense, and was portrayed by the opposition Rikken Seiyukai party as having been forced upon Japan by a hostile United States, which further inflamed growing anti-foreign sentiment.

The Japanese system of party government finally met its demise with the May 15 Incident in 1932, when a group of junior naval officers and army cadets assassinated Prime Minister Inukai Tsuyoshi. Although the assassins were put on trial and sentenced to fifteen years' imprisonment, they were seen popularly as having acted out of patriotism and the atmosphere was set where the military was able to act with little restraint.

Growth of military adventurism[]

Japan had been involved in the Asian continent continuously from the First Sino-Japanese War, Boxer Rebellion, Russo-Japanese War, World War I and the Siberian Intervention. During the term of Prime Minister Tanaka Giichi from 1927 to 1929, Japan sent troops three times to China to obstruct Chiang Kai-shek's unification campaign. In June 1928, adventurist officers of the Kwantung Army embarked on unauthorized initiatives to protect Japanese interests in Manchuria, including the assassination of a former ally, warlord Zhang Zuolin, in hopes of sparking a general conflict.

The Manchurian Incident of September 1931 did not fail, and it set the stage for the Japanese military takeover of all of Manchuria. Kwangtung Army conspirators blew up a few meters of South Manchurian Railway Company track near Mukden, blamed it on Chinese saboteurs, and used the event as an excuse to invade and seize the vast territory.

In Tokyo one month later, in the Imperial Colors Incident, military figures failed in an attempt to establish a military dictatorship, but again the news was suppressed and the military perpetrators were not punished.

In January 1932, Japanese forces attacked Shanghai in the First Shanghai Incident, waging a three-month undeclared war there before a truce was reached. The civilian government in Tokyo was powerless to prevent these military adventures, and instead of being condemned, the Kwangtung Army's actions enjoyed considerable popular support.

Inukai's successors, military men chosen by Saionji Kinmochi, the last surviving genrō, recognized Manchukuo and generally approved the army's actions in securing Manchuria as an industrial base, an area for Japanese emigration, and a potential staging ground for war with the Soviet Union. Various army factions contended for power amid increasing suppression of dissent and more assassinations. In the February 26 Incident of 1936, the Army's elite First Infantry Division staged an attempted coup d'état in yet another effort to overthrow civilian rule. The revolt was put down by other military units, and its leaders were executed after secret trials. Despite public dismay over these events and the discredit they brought to numerous military figures, Japan's civilian leadership capitulated to the army's demands in the hope of ending domestic violence. Increases were seen in defense budgets, naval construction (Japan announced it would no longer accede to disarmament treaties), and patriotic indoctrination as Japan moved toward a wartime footing.[3]

In November 1936, the Anti-Comintern Pact, an agreement to exchange information and collaborate in preventing communist activities, was signed by Japan and Germany (Italy joined a year later). War was launched against China with the Marco Polo Bridge Incident of July 7, 1937 in which a clash near Beijing between Chinese and Japanese troops quickly escalated into the full-scale warfare of the Second Sino-Japanese War, followed by the Soviet-Japanese Border Wars and the Pacific War.

Despite the military's long tradition of independence from civilian control, its efforts at staging a coup d'état to overthrow the civilian government, and its forcing Japan into war through insubordination and military adventurism, the military was ultimately unable to force a military dictatorship on Japan.

Under Prime Minister Konoe Fumimaro, the Japanese government was streamlined to meet war-time conditions and under the National Mobilization Law was given absolute power over the nation's assets. In 1940, all political parties were ordered to dissolve into the Imperial Rule Assistance Association, forming a single party state based on totalitarian values. Even so, there was much entrenched opposition from the government bureaucrats, and in the 1942 general election for the Japanese Diet, the military was still unable to do away with the last vestiges of party politics. This was partly due to the fact that the military itself was not a monolithic structure, but was rent internally with its own political factions. Even Japan's wartime Prime Minister, Hideki Tōjō, had difficulty controlling portions of his own military.

Japan's overseas possessions, greatly extended as a result of early successes in the Pacific War were organized into a Greater East Asia Co-Prosperity Sphere, which was to have integrated Asia politically and economically—under Japanese leadership—against Western domination.

Opposition to militarism[]

Despite the apparently monolithic national consensus on the official aggressive policies pursued by the Imperial government in the first part of the Shōwa era, some political opposition did exist. Some notable examples include:

  • Hara Takashi, a commoner and liberal thinker of the Rikken Seiyūkai, had become prime minister in 1918 with the rallying cry of "Militarism is dead." Three years later, however, Hara was assassinated.
  • Kijūrō Shidehara followed a non-interventionist policy toward China, attempting to stabilize its relations with Great Britain and the United States. The term "Shidehara diplomacy" came to describe Japan's liberal foreign policy during the 1920s, and was assailed by military interests who believed it was weakening the country.
  • Baron Takuma Dan, director of Mitsui Bank, was an important opponent of Japan overseas interventions and was known for his pro-American views. He was murdered on March 5, 1932 in the League of Blood Incident.
  • Minobe Tatsukichi, a respected professor at Tokyo Imperial University declared the emperor to be a part of the constitutional structure of Japan rather than a sacred power beyond the state itself in 1935. His constitutional interpretation was overwhelmingly accepted by bureaucrats until the 1930s. In the increasingly militant 1930s, these ideas led to attacks against Minobe in the House of Peers and his resignation from that body.
  • Saitō Takao, a graduate of Yale University was a member of the Rikken Minseito party. On February 2, 1940, he made a speech in the Diet in which he sharply questioned the prosecution and justification of Japan's "holy war" in China. He was expelled from the Diet on March 7, 1940 and his speech also led to the creation of the League of Diet Members Believing the Objectives of the Holy War by Fumimaro Konoe.
  • Admiral Sōkichi Takagi, an opponent of Japan's decision to declare war on the United States, was asked by Navy Minister Shigetarō Shimada to compile a report analyzing Japanese defeats during the Pacific campaign of 1942. His analysis convinced Takagi of Japan's inevitable defeat. Believing that the only solution for Japan was the elimination of the Tojo-led government and a truce with the United States, Takagi began planning for the assassination of Prime Minister Hideki Tōjō before his removal from office in July 1944.
  • Kanō Jigorō, creator of Judo and founder of the modern Japanese educational system, member of Japan's Olympic Committee, and de facto foreign minister for Japan was a staunch opponent of militarism. Concerned that his Judo school, the Kodokan, would be used as a military training center, he obtained a promise from the Emperor that it would not be. Alternate sources list different causes of death, and some consider his passing to be suspicious.


Despite efforts to totally militarize Japanese society during the war, including such measures as the National Service Draft Ordinance and the National Spiritual Mobilization Movement, Japanese militarism was discredited by the failure of Japan's military in World War II and by the American occupation. After the surrender of Japan, many of its former military leaders were tried for war crimes before the Tokyo tribunal, its government, educational system revised and had pacifism written into the post-war Constitution of Japan as one of its key tenets.

While many believe that nationalism is on the rise, due to the country's economical downfall and increased push to revise article nine to assist in international peacekeeping operations, many also believe that it has very little to do with militarism in general. [1]
