The All-Japan Prefectural and Municipal Workers' Union (Japanese: 全日本自治団体労働組合, Jichiro) is a trade union representing local government workers in Japan.
The union was established in January 1954, with the merger of two smaller unions of local government workers.[1] It was affiliated with the General Council of Trade Unions of Japan and grew rapidly, attaining 559,397 members by 1967.[2] By 1987, it was the largest union in the country, with 1,257,000 members. In 1989, it became affiliated with the Japanese Trade Union Confederation.[3] Members who objected to this affiliation left and formed the rival Japan Federation of Prefectural and Municipal Workers' Unions.[4]
The union absorbed the National Union of General Workers in 2006 and the All Japan Municipal Transport Workers' Union in 2013.[5] Despite this, by 2020, its membership had declined to 785,445, though it was still Japan's second-largest union.[6]
