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.
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.
