On the main island of Okinawa, in Onna Village, the Okinawa Institute of Science and Technology Graduate University (OIST) runs a graduate school built around a five-year PhD programme in science, taught entirely in English. Plans for a new international graduate university in Okinawa were announced in June 2001, OIST was established in 2011, and the first graduate students were welcomed in September 2012.
OIST has no academic departments. Each faculty member leads an independent research unit, and courses cut across disciplines instead of following departmental lines. Research and teaching cover the life sciences, the natural sciences and engineering, and the main campus is located in Tancha, Onna Village.
The community is small and international. In 2026 the institute reported about 300 PhD students and fewer than 100 faculty members, with students coming from about 50 countries and territories and a majority of both students and faculty recruited from outside Japan. OIST is a private institution, yet it is funded mostly by the Japanese government, and doctoral students receive financial support that covers tuition and living expenses.
