The Military Academy incident, also known as the November incident was an attempted coup d'état that took place in Japan in November 1934. It was one of a sequence of similar conspiracies for a "Shōwa Restoration" led by radical elements with the Imperial Japanese Army.
Background
The failed coup attempts in 1931 by the Sakurakai , a secret society within the junior ranks of the Imperial Japanese Army officer corps promoting a vision of a militaristictotalitarian, state socialist system as an alternative to the current corrupt party politics dominated democratic government, inspired similar plans by other groups within the military. In 1934, a group of five Imperial Japanese Army Academy cadets led by two army officers belonging to the radical militarist Imperial Way Faction at the academy, troubled by the perceived loss of influence of their faction over the military following the dismissal of Army MinisterSadao Araki in January 1934, formulated their own plan for overthrowing the government. However, in early November 1934, Sato, one of the cadets, informed the government authorities about the plan and its Imperial Way Faction involvement. Forewarned, Captain Tsuji Masanobu, company commander at the Army Academy, arranged the arrest of the principals by the Kempeitai on 20 November 1934, ending the possible coup d'état before it could even get started. For lack of evidence, the accused could not be convicted; but the five cadets were expelled from the Academy in March 1935, and the two officers, Muranaka and Isobe were suspended for six months from duty in April 1935. When the suspended officers Muranaka and Isobe later distributed pamphlets entitled "Remonstrance for the Restoration of Military Discipline", they were dismissed from the service outright in August 1935.
The Military Academy Incident and the Aizawa Incident were indicative of the increasing politicization and political polarization of the Japanese military, and an increasing tendency to resolve political differences through force. The lack of action within the military leadership to suppress these tendencies, and the powerlessness of the civilian elected government over the military were contributing factors that led to the subsequent February 26 Incident.
