was a political faction in the Imperial Japanese Army, active in the 1920s and 1930s. Led by Major General Tetsuzan Nagata, along with Hideki Tōjō, the Tōseiha was a grouping of officers united primarily by their opposition to the Kōdōha faction led by General Sadao Araki and Jinzaburō Masaki. The name "Tōseiha" was actually a pejorative coined by (and only used by) Kōdōha members and sympathizers.
