Control faction

One of the two ultranationalist factions of the Imperial Japanese Army in the 1930s, the Control faction (toseiha) was led by Kazushige Ugaki and included Hideki Tojo and Tetsuzan Nagata. It supported a general economic and technological expansion, rather than the spirituality of the rival Imperial Way faction.

Both factions believed in military expansion and colonialization, but this faction backed the eventual Strike-South movement aimed at the East Indies and Malaya, while the Imperial Way backed Strike-North into Manchuria and the Soviet Union. The February 26 Incident of 1936, a coup attempt by young officers associated with Imperial Way, was crushed on orders of Emperor Hirohito and power shifted to the minority Control faction.

Masanobu Tsuji affiliated himself with Tojo and his group.
