OIST PhD Program

OIST says its PhD programme is fully funded for every student, regardless of nationality or citizenship. The funding covers tuition in full and pays a research assistantship meant to give a comfortable standard of living: about 2.6 million yen a year in the first year, which is taxable, rising with academic progress to about 3.6 million yen.

OIST pays new students' moving and travel costs to Okinawa, and travel to conferences and other institutions is budgeted separately. Students are covered by the Gakkensai personal accident and liability insurance for students in education and research, and the campus has its own clinic and health centre.

Students must live on campus for at least their first year, in subsidised apartments in the Campus Village. Rent is 21,600 yen a month for a single apartment and 18,000 yen a month each for a two-room apartment shared by two students, with cheaper unfurnished units available. Because the funding is meant to be enough to live on, students may not work part-time elsewhere.

Students are admitted to the programme, not to a laboratory. In the first year they do research rotations in three different units alongside basic and advanced courses, and they join a unit at the end of that year. The second year combines thesis research with the remaining courses and ends with a qualifying examination that leads to candidacy. Years three to five are given to the thesis.

OIST has no departments and more than 90 research units, so students can move between disciplines. Students entering with a bachelor's degree need at least 30 credits, and those with a STEM master's at least 20. Some earlier graduate STEM courses can be transferred, at one OIST credit for every 20 hours of face-to-face teaching and no more than two credits per course. A credit-bearing course in professional and career development is required to graduate.

Applicants need a bachelor's, master's or equivalent degree, completed or expected before they enrol; a master's is not required. There is no nationality restriction, and OIST encourages applications from women and underrepresented groups.

Applicants whose degree was not taught in English submit a TOEFL iBT or IELTS score from the last two years. There is no minimum score: the result is used to decide whether a student needs preparatory courses. GRE scores are optional. OIST does not take students from the Japanese government's MEXT scholarship programme directly, because the two use different selection criteria.

Admitted students choose one of three start dates. For the round closing in November 2026 these are 1 May 2027, 1 September 2027 and 1 January 2028, and the choice can be changed only once. About three months before arrival the relocation and visa process begins and each student is assigned a mentor and builds an academic plan with rotation preferences; rotation assignments are made about three weeks before the start.

The campus sits on a subtropical hillside in Onna village. For families, the Child Development Center takes children from two months to six years and the School Aged Program children from 5 to 14, with fees based on income and classes in English and Japanese. PhD students have eight weeks of paid leave after giving birth, with prenatal leave before it, and partners have eight weeks of paid childbirth leave. Partners can look for technical, research and administrative posts on the OIST careers page, though OIST notes that most employers need Japanese.
