Constitutional Democratic Party (Japan)
|Founded||June 1, 1927|
|Dissolved||August 15, 1940|
|Merged into||Imperial Rule Assistance Association|
The Minseitō was founded on 1 June 1927, by a merger of the Kenseikai and the Seiyu Hontō political parties. Its leadership included Osachi Hamaguchi, Wakatsuki Reijirō, Yamamoto Tatsuo, Takejirō Tokonami, Adachi Kenzō, Koizumi Matajirō and Saitō Takao. The party platform was politically and economically more liberal than its major rival, the Rikken Seiyūkai, calling for rule by the Diet of Japan rather than bureaucrats or genrō, elimination of disparities in wealth, international cooperation, and protection of personal liberties. Its main base of support was the urban middle class, but its principal financial backing was the Mitsubishi zaibatsu.
The Minseitō fielded many candidates in the February 1928 General Election, (the first to be held after the General Election Law), winning 217 seats in the Lower House, as opposed to 218 seats for the Seiyūkai. This resulted in a hung parliament.
In the following 1930 General Election, the Minseitō took 273 seats, as opposed to 174 seats for the Seiyūkai, which gave it an absolute majority. Minseitō president Osachi Hamaguchi, Herbert Bix referred to him as Hamaguchi Yūkō, became Prime Minister. Hamaguchi’s first priority was to address the effects of the 1929 Stock Market Crash through retrenchment of government spending, tightening the money supply and encouraging exports while stabilizing foreign investments through returning to a fixed exchange rate.
During its tenure, the Minseitō also advocated a conciliatory foreign policy, and ratified the London Naval Agreement of 1930. However, Hamaguchi fell victim to an assassination attempt on 14 November 1930 when he was shot in Tokyo Station by a member of an ultranationalist secret society. Wakatsuki Reijirō became acting Prime Minister, also from the Minseitō.
In 1931, Minseitō strongly opposed the Mukden Incident which was engineered by the Imperial Japanese Army. The anti-war Foreign Minister Kijūrō Shidehara and Prime Minister Reijirō came under strong criticism for their intervention in military affairs, and were accused of "serious corruption", and his government collapsed in 1931.
The Minseitō was able to recover a very slight majority of 205 seats versus 175 seats for the Seiyūkai in the 1936 General Election only by adopting a more pro-military stance. However, the narrow margin again resulted in a hung parliament. The Minseitō dropped back down to 179 seats in the 1937 General Election, while the Seiyūkai retained all of its 175 seats, which continued the paralysis in the Diet of Japan.
