The National Federation Of Industrial Organisations (FIO, Japanese: 全国産業別労働組合連合, Shinsanbetsu) was a national trade union federation in Japan.
The federation was a split from Sanbetsu, which took place in 1952.[1] Always a small organisation, by 1967 it had only three affiliates and a total of 69,839 members.[2] By 1978, it had 61,000 members, and that year, it formed a loose association with the Federation of Independent Unions (Churitsuroren), intending to merge in the future.[3] In 1987, it merged with both Churitsuroren and the larger Japanese Confederation of Labour, to form the Japanese Trade Union Confederation.[4]
