Sasebo Naval District
Before he was chosen as the Prime Minister, Yonai showed strong leadership particularly in crisis. On February 26, 1936, there was an attempted coup d'état led by young officers of the Imperial Japanese Army. The generals of the Imperial Japanese Army struggled to decide the appellation of the rebel troops, whom the generals were hesitant to refer to as rebels because it was extremely shameful for them to admit internecine strife. Hence, the generals were hesitant. On the other hand, Yonai, the commander-in-chief of the Sasebo Naval District, instantaneously labeled them as "Insurrectional troops", (Agawa, n.d.) and let the chief of his staff, Admiral Inoue Shigeyoshi, publish his position to all the Sasebo Naval District. Because of this immediate announcement, navy officers in the Sasebo Naval District were compelled to stop participating with the rebellion troops. Yonai's prompt action as the supreme commander tranquilized the Sasebo Naval District.
