About JOCA

Broadly giving back to society, based on the attitudes developed and experiences gained as JOCV volunteers

The Japan Overseas Cooperative Association (JOCA) is an organization, composed chiefly of former Japan Overseas Cooperation Volunteers who have drawn on their skills and experiences to promote the welfare of those living in developing countries. In spreading the attitudes developed and experiences gained by JOCV volunteers for the benefit of as many as possible, JOCA seeks to play a constructive role in international society and expand the number of cooperative activities, in addition to serving as a leader in international exchange and international cooperation with roots in local communities. To do this, JOCA draws on a network consisting of numerous organizations, including former volunteer associations.

Background of JOCA

On April 26, 1969, the first group of 26 volunteers in the organization preceding today's Japan Overseas Cooperation Volunteers program returned to Japan after completing their service and formed the Association of Former JOCV Volunteers, whose goal was to contribute to international goodwill and world peace while strengthening mutual understanding and cooperation in Japan and among citizens of other countries. These first volunteers planned to enhance their networks while applying the valuable experiences gained overseas to provide support for and to promote participation in JOCV programs. As a private organization at the time, it organized various activities, including conferences for families whose members were away on the volunteer program, recruitment drives, interviews with volunteers concerning experiences in the field (meetings in which returning volunteers reported on their experiences), and public relations.

During the 1970s, 47 prefectural associations of former volunteers were formed. Since then, these associations have pursued various activities to promote international understanding and cooperation in local communities. As the reputation of the volunteer program and of volunteers after returning to Japan grew, so did the expectations of various parties. JOCA was founded on December 27, 1983, and certified by the Ministry of Foreign Affairs. On Febuary 1, 2012 JOCA was certified as Public Interest Incorporated Associations by Cabinet Office. Associations of former JOCV volunteers form the core of the organization.

Charter of JOCA

An accurate understanding of Japan's position in the world is a crucial issue to all of us today. In particular, experience in international cooperation activities is crucial to ensuring that young people, on whose shoulders rests the responsibility of building an international society in which people can live together, have an accurate understanding of world conditions. This is an essential condition for a meaningful life.

Despite the promise young people represent and the expectations they shoulder, they have limited opportunity to play important roles in today's society. In today's world, international cooperation and international exchange are valuable areas in which young people can channel their enthusiasm and energy.

The countless individuals living around the world each live unique and irreplaceable lives, based on their own individual values. Promoting respect and understanding is the greatest duty of the Japanese people, who must play a constructive role in the international society of the future. Based on this perspective, we hereby establish the Japan Overseas Cooperative Association (JOCA) to assume, maintain, and promulgate the outlook cultivated by JOCV volunteers over the years and to deploy a broad range of international cooperation activities, drawing on the joint efforts of youth around the world to help build a new international society.
