立憲民政党
In 1931, the ruling Rikken Minseitō opposed the Mukden Incident, which was engineered by the military. The anti-war Foreign Minister Kijuro Shidehara and Prime Minister Wakatsuki Reijirō were criticized for their intervention in military and was accused of "serious corruption". After the resignation of the Reijirō Cabinet, some right-wing members of the ruling party formed a coalition with the opposition Rikken Seiyūkai and elected Inukai Tsuyoshi as prime minister.
