Senjuro Hayashi (1876-1943) was an Imperial Japanese Army General, who was briefly Prime Minister of Japan in 1937, serving simultaneously as Minister of Education. He had served as Inspector General of Military Education.
Prince Kanin sent him, as Minister of War, to ask for the resignation of Tetsuzan Nagata for involvement in the March 1931 Incident. Earlier, he had purged many of the supporters of Sadao Araki, Nagata's opponent.
He had been Minister of War in the Saito cabinet, but Hayashi resigned over scandal regarding "his younger brother Yukichi who had been adopted as a child by the family of Shirakami and taken that name. The General felt that he was still responsible for his brother's acts, whatever his name, and Yukichi, as Deputy Mayor of Tokyo, had been convicted of accepting a bribe to permit Tokyo Gas Co. to increase its capitalization....Meanwhile a faction of young army officers was rumored busy building up Hayashi's resignation into a reason why Premier Saito's entire cabinet should resign. When Hayashi got wind of that, his temper changed. Prince Kanin spoke, against the resignation. With great relief Hayashi withdrew his resignation. "
