The February 26 incident was an attempted coup d'état in the Empire of Japan on 26 February 1936. It was organized by a group of young Imperial Japanese Army (IJA) officers with the goal of purging the government and military leadership of their factional rivals and ideological opponents.
Although the rebels succeeded in assassinating several leading officials (including two former prime ministers) and in occupying the government center of Tokyo, they failed to assassinate Prime Minister Keisuke Okada or secure control of the Imperial Palace. Their supporters in the army made attempts to capitalize on their actions, but divisions within the military, combined with Imperial anger at the coup, meant they were unable to achieve a change of government. Facing overwhelming opposition as the army moved against them, the rebels surrendered on 29 February.
Unlike earlier examples of political violence by young officers, the coup attempt had severe consequences. After a series of closed trials, nineteen of the uprising's leaders were executed for mutiny and another forty were imprisoned. The radical Kōdō-ha faction lost its influence within the army, while the military, now free from infighting, increased its control over the civilian government, which had been severely weakened by the assassination of key moderate and liberal-minded leaders.
The Imperial Japanese Army (IJA) had a long history of factionalism among its high-ranking officers, originally stemming from domainal rivalries in the Meiji period. By the early 1930s, officers in the high command had become split into two main informal groups: the Kōdō-ha "Imperial Way" faction led by General Sadao Araki and his ally General Jinzaburō Masaki, and the Tōsei-ha "Control" faction identified with General Tetsuzan Nagata.
The Kōdō-ha emphasized the importance of Japanese culture, spiritual purity over material quality, and the need to attack the Soviet Union (Hokushin-ron), while the Tōsei-ha officers, who were strongly influenced by the ideas of the contemporary German general staff, supported central economic and military planning (total war theory), technological modernization, mechanization and expansion within China (Nanshin-ron).
