First WCSJ was held in Tokyo
In 1992, the future founders of JASTJ, a group of science journalists working for newspaper publishing companies and TV stations, organized the First World Conference of Science Journalists (WCSJ) in Tokyo under the sponsorship of the United Nations Educational, Scientific and Cultural Organization (UNESCO).
Their concerted efforts made the meeting a great success, with 165 participants from 31 countries. That accomplishment taught the founding members the value and significance of establishing an association of science and technology journalists in Japan. JASTJ was to be born two years later.
