Japanese militarism

While Japan has always had a strong individual warrior tradition (e.g., bushido), Japanese militarism primarily refers to the increasingly important role of the organized military in government, beginning with the Meiji Restoration of 1838. Radical military officers had a considerable role in starting World War Two in the Pacific, particularly in the 1920-1940 period.

While the usual meaning of the term deals with matters prior to 1945, Edwin Hoyt and others argue that there may be a post-1945 trend toward militarism. They argue that Article 9 of the postwar Constitution, banning war as an instrument of national policy, has not been fully effective.

Why militarism?

While there is much historical work on what these officers did, there has been much less analysis on why the Japanese system of government could be so affected by them. One reviewer summarizes theories that include:

• "A breakdown of the decision-making processes in the civilian and military sectors;
• an internal response to external traditions
• poor leadership
• the inherent Japanese military tradition
• a reaction against urbanization
• the plot or plan thesis versus the drift-into-war thesis.

Another set of reasons, which considers Western imperialism as the key driver, is:

• Japan's desire to be a Western-style imperialist power
• Japan's concerns for its security
• Japan's belief in its leadership role for Asia
• Japan's frequent provocations by Western powers
• Japan's desire to secure its economic interest

Cultural factors

The shishi movement, which began with emphasis on supporting the Emperor, was based of kokutai, or the Japanese national polity for which the Emperor was father figure, and sometimes a deity. As such, the shishi have been considered predecessors of the militarism of the 20th century.

Gekokoju became, in the 1920s and 1930s, an insitutionalized system of insubordination by junior and mid-level officers. Its theory held that obedience to superiors was less important than obedience to principles, above all, that of national polity or kokutai. It can also be be translated as "insubordination", but as a means of redressing social injustice, which arose in the fifteenth century when provincial lords disobeyed the shogun and the shogun disobeyed the emperor.

It could justify assassinations and overthrows of government. Gekokoju was practiced both by middle and senior officers against the government, as in the Manchurian Incident, and by junior officers, as in the February 26, 1936 Incident.
