The National Tax Collectors' Union (ja|全国税労働組合, Zenkokuzei) is a trade union representing tax agency workers in Japan.
The union was established in 1946, and affiliated to the General Council of Trade Unions of Japan.[1] By 1958, it had 31,986 members,[2] but that year, it suffered a major split, as the right wing of the union left to form the Japanese Confederation of National Tax Unions. By 1970, it was down to only 3,209 members,[3] and in 1975 it merged into the Japan Federation of National Public Service Employees' Unions, while retaining its own identity. By 1990, its membership had fallen further, to just 1,309.
