Japan Overseas Cooperation Volunteers Day

What Is Japan Overseas Cooperation Volunteers Day?

Every April 20th is "Japan Overseas Cooperation Volunteers Day" (青年海外協力隊の日, Seinen Kaigai Kyōryoku-tai no Hi) in Japan. It commemorates April 20, 1965, when the Japan Overseas Cooperation Volunteers (JOCV, 青年海外協力隊) program was launched. Carried out today by JICA (Japan International Cooperation Agency, 国際協力機構) as part of Japan's Official Development Assistance, the program has sent tens of thousands of Japanese volunteers to developing countries over the following six decades.

The Japan Overseas Cooperation Volunteers

The JOCV was launched in 1965, partly influenced by the creation of the U.S. Peace Corps in 1961. Its first destination was Laos in Southeast Asia. The program was originally run by the Overseas Technical Cooperation Agency, whose work was later taken over by JICA. Volunteers typically serve assignments of one to two years, contributing their skills in fields such as agriculture, education, health, and sports. According to JICA, as of the end of March 2026, a cumulative total of more than 49,000 JOCV volunteers had been dispatched to 94 countries, and more than 58,000 when the senior and other JICA volunteer programs are included.

The Road to Deployment

Applications are usually accepted twice a year, in spring and autumn. Successful applicants undergo about 70 days of pre-dispatch training at the Nihonmatsu Training Center in Fukushima Prefecture or the Komagane Training Center in Nagano Prefecture. Language training is at the core of the program — learning the local language is the starting point for building trust in the host country.

The Experience of JOCV Service

Volunteers learn the local language and work alongside local people in the same workplaces, tackling challenges together. Although the program is often associated with "digging wells in Africa," actual activities vary widely by country and job type — there are more than 170 job categories, including Japanese-language teaching and sports coaching. Many JOCV alumni go on to work in education, local government, business, and international cooperation, bringing their experience of mutual understanding into their professional lives.
