All students receive an internationally competitive financial support package. OIST offers financial support comparable to that offered by other leading research universities.

Students in the PhD program are expected to engage full-time in advanced study and research. Financial support of 2.4 million yen per year (taxable) is provided for each year of approved full-time study, which is sufficient to ensure a comfortable standard of living. Course fees will also be covered. Students additionally receive support for relocation to Okinawa, a personal computer and financial support for educational travel and conference attendance.

While the University maintains financial support system, students are strongly encouraged to apply for external fellowships. In order to reward success, remuneration provided by the university as an OIST Research Assistantship or Teaching Assistantship may be used to supplement external fellowships, up to a maximum of 3.0 million yen total, which is 0.6 million yen above the standard level.
