Labour-Farmer Party
The revolutionary left was also divided within own ranks. After the disbanding of the first Japanese Communist Party in 1924, leftwing cadres had joined the Labour-Farmer Party. One sector (the Fukumoto group) wanted to reconstitute the Communist Party and concentrated their work on underground organizing, whilst Sakai Toshihiko, Yamakawa Kikue, Yamakawa Hitoshi and their sympathizers focused on building the legal Labour-Farmer Party. By the end of 1926, the Fukomoto group dominated both the reconstituted Communist Party and the Labour-Farmer Party, holding key strategic positions inside the latter.
