Sōhyō
（重定向自General Council of Trade Unions of Japan）
The General Council of Trade Unions of Japan(日本労働組合総評議会nihonrōdōkumiaisouhyogikai), often abbreviated to Sōhyō(総評), was a left-leaning union confederation. Founded in 1950, it was the largest in Japan.
A large portion of Sōhyō merged with the more conservative Japanese Confederation of Labor (Domei) and other unions to form Rengo in 1987. Rengo was formally launched in 1989. Some elements of Sōhyō also joined the National Trade Union Council (Zenrokyo).
