The Federation of Electric Power Related Industry Workers' Unions of Japan (Japanese: 全国電力関連産業労働組合総連合, Denryoku Soren) is a trade union representing workers in the electric power industry in Japan.
The most important of these was the Federation of Electrical Workers' Unions of Japan.
In 1981, the council was replaced by Denryoku Soren, a more centralised organisation, which by this time had 209,523 members.
It was then a founder of the Japanese Trade Union Confederation, in 1989.
[1][3] In 1996, it absorbed the small National Council of Japanese Electric Powers Workers.
