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.
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.
In response to a Japanese request, Prussian Chief of Staff Helmuth von Moltke sent Meckel to Japan to become an O-yatoi gaikokujin (foreign advisor).
[7] 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.
The phrase fukoku kyōhei (rich nation, strong army) was created during this time and shows how Japanese officials saw imperialism as the way to gain respect and power.
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.
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 large when the military made any demands on the civilian leadership.
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.
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.
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.
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.
Kwantung 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.
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.
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.
[5] 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).
[13] 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 substantial opposition did exist.
