Japanese Federation of Labour
The Japanese Federation of Labour ( Nippon Rōdō Kumiai Sōdōmei) was a national trade union federation in Japan. The federation was established in 1946, principally through the efforts of trade unionists who had been involved in the pre-war Japanese Labour Federation. The new federation aligned itself with the Japan Socialist Party. By 1948, it claimed a total of 924,302 members, slightly less than its communist rival, Sanbetsu. In 1950, many affiliates left to join the new General Council of Trade Unions of Japan, and by 1954, membership of Sodomei affiliates had fallen to 240,000. That year, many of its remaining affiliates split away to join the new All-Japan Trade Union Congress (Zenro), the surviving Sodomei being a small, conservative group with seven affiliates. In 1964, it merged with Zenro and the National Council of Government and Public Workers' Unions, to form the Japanese Confederation of Labour. Affiliates
