The All-Japan Trade Union Congress (), better known by its Japanese abbreviation Zenrà Â) was a national trade union federation that existed in Japan from 1954 to 1964.
Zenrà  was established in 1954 by a number of unions on the right wing of the trade union movement, who had become unhappy with the increasingly left-wing political stance of the General Council of Trade Unions of Japan (Sà Âhyà Â) under the leadership of its militant secretary-general Minoru Takano. Politically speaking, Zenrà  was tied closely to the Right Socialist Party (RSP), to whom it provided electoral support, and following the reunification of the Japan Socialist Party (JSP) in 1955, supported the former RSP factions in the new party, especially the far-right faction led by Suehiro Nishio.
Although Zenrà  generally shied away from political actions and even purely economic strikes, preferring a more conciliatory relationship with management, the federation did participate in the successful struggle in 1958 to defeat the revision of the Police Duties Bill proposed by conservative prime minister Nobusuke Kishi, which opponents were able to portray as less of a left-right issue and more of a basic threat to Japanese democracy and civil rights.
However, Zenrà  was less enthusiastic about supporting the 1960 Anpo protests against the US-Japan Security Treaty, and ultimately pulled out of the movement when the JSP insisted that the Japan Communist Party be allowed to participate. This controversial decision also caused Nishio and the other right socialists to bolt the JSP and form the new Democratic Socialist Party, which Zenrà  thereafter supported. Not that the left socialists and Sà Âhyà  were necessarily sorry to see Zenrà  and Nishio gone, as Zenrà  had purchased Sà Âhyà Â's enmity by repeatedly attempting to hive off Zenrà Â-affiliated "second unions" within Sà Âhyà Â-controlled shop floors.
In 1964, Zenrà  merged with the National Council of Government and Public Workers' Unions (Zenkankà Â) and the Japanese Federation of Labour (Sà Âdà Âmei), to form the Japanese Confederation of Labour, better known as Dà Âmei.
The following unions were affiliated in 1956.
