The Japanese Federation of Labour (Japanese: 日本労働組合総同盟 Nihon Rōdō Kumiai Sōdōmei) was a national trade union federation in Japan.
The new federation aligned itself with the Japan Socialist Party.
[1] By 1948, it claimed a total of 924,302 members, slightly less than its communist rival, Sanbetsu.
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.
