To promote international scientific cooperation, the Japan Society for the Promotion of Science encourages highly qualified researchers from the worldover to come to and conduct joint research activities with colleagues at Japanese universities and research institutes.

During the 2002 fiscal year, 4296 researchers from 91 countries did research in Japan under JSPS programs. Virtually all of them expressed satisfaction with the Japanese research environment and achieved substantial results.

JSPS offers six fellowship programs, each with different eligibility requirements.
