The History of JAW
After the end of the World War II, the Occupation Forces (GHQ) and the government consider that the liberalization of trade union movement was one of the essential factor for the emancipation and democratization of post-war Japan.
In 1946, the Trade Union Law and the Labor Relations Adjustment Law were enacted. Thus, numbers of unions were formed under the GHQ's instructions.
The post war democratization period in Japan gave company-unit labor union a major role to play in Japanese labor union organization.

1948 Zen Jidosha (All Japan Auto Workers' Union) was formed.
Industry-wide union.
Automobile labor unions were positioned as a regional branch of Zen Jidosha.

As a result of control of the hyper inflation policy, Japanese economy was depressed. With a rising movement of labor democratization, labor disputes occurred one after another.
During the Korean War in 1950, Japanese economy was recovered. However, after the end of the Korean War, Japan once again experienced economic recession.

1954 Zen Jidosha dissolved.
This union pursued reckless tactics based on an ideology of class struggle such as disruption in the workplace and strikes for indefinite periods of time. This resulted workplaces in ruin and wage cuts.
Those who doubt its old way of primarily dealing with labor-management relations through dispute began to form a new union where problems to be solved through discussion between labor and management.

1955 Jidosha Roren (Federation of Japan Automobile workers' Unions) was formed.
29 unions, 9,200 members.
Later in 1989, the name was changed to "Federation of All Nissan and General Workers' Unions".

1962 Zenkoku Jidosha was formed.
36 unions, 30,000 members.
Toyota, Hino, Isuzu, Suzuki.
Toyo Kogyo (Mazda) and Honda did not participate, as they thought it is meaningless to join the organization in which Nissan does not participate.

*As for the relationship to upper organization, they can be divided into three groups.
Zenro group: Nissan, Mitsubishi, Daihatsu.
Churitsu group: Toyota, Hino, Isuzu, Suzuki, Toyo Kogyo (Mazda), Honda.
Sohyo group: Fuji, Prince.

In preparation for liberalization of importing assembled automobiles in Oct 1965, reorganization and strengthening of the automobile industry were needed. Also for labor unions, change of organization structure was required to cope with this movement.

1965 Council of Japan Automobile Workers' Unions was formed.
Industry-wide organization with 220,000 members.

Around 1965, along with automobile boom, production of automobiles increased drastically and at the same time the number of union members also grew.

However, the Council of Japan Automobile Workers' Unions was ultimately unable to do anything more than provide a platform for discussions between member unions. It was therefore confirmed at the general annual meeting in 1971 that its status would be changed to that of a federation in 1972.

1972 Confederation of Japan Automobile Workers' Unions (JAW) was formed.
Industry-wide organization with 12 federations, 500,000 members.
