Political careerEdit

Senjūrō Hayashi as Prime Minister in 1937

From 1934 to 1935 Hayashi was Army Minister, and again member of the Supreme War Council from 1935 until his retirement the next year.

As Army Minister, Hayashi was a supporter of Major General Tetsuzan Nagata, who was Chief of Military Bureau and the leader of the Tōseiha faction within the Imperial Japanese Army.[according to whom?] The Tōseiha scored a victory in July 1935 when General Jinzaburō Masaki, one of the leaders of the Kōdōha faction was removed as Inspector General of Military Training. But Nagata was assassinated the next month(the Aizawa Incident). The struggle between the Tōseiha and Kōdōha factions continued below the surface of the government; and the war in North China carried on apace until February 1936.

Hayashi also promoted Fumimaro Konoye's doctrines, as a "right-winger" amongst the militarists, who approved of the "fiction" of democracy, and the Emperor's role with an "adviser group", against "left-winger" radical militarists, led by Kingoro Hashimoto, wanted a Military Shogunate.

Hayashi also happen to the president of Greater Japan Muslim League (大日本回教協会, Dai Nihon Kaikyō Kyōkai).[3]

Hayashi served as Prime Minister of Japan for a brief four-month period in 1937. Later from 1940 to 1941, he was a Privy Councillor. Hayashi suffered from an intracranial hemorrhage in January 1943 and died at his home of 4 February without regaining consciousness.
