労働農民党
The 1926 split in the Social Democratic Party was followed by a split in the "Sodomei" trade union centre. The leaders of the Japan Labour-Farmer Party were asked to resign from their leadership positions in "Sodomei", as they refused they were expelled from the organization. The Japan Labour-Farmer Party regrouped their followers in the labour movement and formed a new trade union centre of their own, the Japan Labour Union League. In February 1927, farmers sympathizing with the party broke away from the Social Democratic Party-led General Federation of Japanese Peasant Unions, and formed the All-Japan Peasant Union as the agrarian wing of the Japan Labour-Farmer Party. In October 1927, a women's organization connection to the party was formed, the National Women's League.
