労働農民党
The party was founded on December 5, 1926 by the Japan Federation of Labour ("Sōdōmei"), other trade unions and the Independent Labour Association, an organization of moderate leftist intellectuals. Abe Isoo was elected chairman of the party. Suzuki Bunji, Nishio Suehiro, Akamatsu Katsumaro, Shimanaka Yuzō and Kagawa Toyohiko were Central Committee members of the party. The elements which formed the new party had belonged to the Labour-Farmer Party, which opposed the inclusion of leftists in the latter party. "Sodomei" and other trade union had pulled out of the Labour-Farmer Party on October 24, 1926. However, only four days after its foundation the new party suffered its first split, as leftwing socialists broke away and formed the Japan Labour-Farmer Party.
