OIST PhD Programme 2027

The Okinawa Institute of Science and Technology Graduate University, known as OIST, is a small graduate-only university on the west coast of Okinawa’s main island. It offers one degree: a five-year PhD in science. There are no departments. Research units in physics, neuroscience, marine science, chemistry, mathematics, computer science, ecology and engineering sit side by side, and students choose courses and rotations across those lines.

Every admitted PhD student is funded, whatever their nationality. That is the main reason to look at OIST alongside government schemes such as the MEXT research scholarship: there is no separate scholarship competition to win after admission, and no embassy stage. If OIST offers you a place, the funding comes with it.

The current round closes on 15 November 2026 at 23:59 Japan time (checked 9 October 2026 on oist.jp). OIST says you can submit at any point before then and the application goes to the next Admissions Committee meeting.

What funded means at OIST

PhD students are paid through a research assistantship. OIST’s student support page says it starts at about 2.6 million yen a year in the first year and rises with progress towards about 3.6 million yen. Both figures are taxable. OIST describes them as enough for a comfortable standard of living “including the tuition fee”, and its October 2025 introduction slides state that tuition of 540,000 yen a year is covered from the assistantship. Read the headline number as a gross figure before tax and tuition, not as take-home pay.

Item	What OIST provides (checked 9 October 2026)
Research assistantship	About 2,600,000 JPY a year in year one, rising with progress to about 3,600,000 JPY; taxable
Tuition	Covered within the support package
Housing	Subsidised Campus Village flats: 21,600 JPY a month for a single furnished unit, or 18,000 JPY a month each when two students share a two-room flat
Relocation	Moving and travel costs to Okinawa paid by OIST
Conference travel	Budgeted separately from the assistantship
Insurance	Student accident and liability insurance (Gakkensai)
Family	On-campus childcare from 2 months, school-age care, and eight weeks of paid leave after childbirth for students and their partners

Students must live on campus for at least their first year. Unfurnished flats are cheaper than the figures above, but OIST does not publish that rate. OIST also expects PhD students to study and research full time and encourages them to apply for outside fellowships on top of the assistantship.

Who can apply

The bar for entry is lower on paper than at many PhD programmes. A master’s degree is not needed.

• A bachelor's, master's or equivalent degree completed before you enrol. Final-year students who expect to graduate in time can apply
• Any nationality and any age. OIST states that it does not discriminate on either and encourages applications from women and underrepresented groups
• A TOEFL iBT or IELTS score from the last two years if your degree was taught or examined in another language. There is no minimum score; the result decides whether you take preparatory English courses
• Two to five recommendation letters in English from faculty at professor level

The GRE is optional. You can add GRE or other test scores from the past two years, along with titles and abstracts of any papers or talks, if they help your case.

How the five years run

The first year is built around rotations. You spend time in three different research units, alongside basic and advanced courses, before choosing where to do your thesis. At the end of that year you move into your thesis lab. Co-supervision across two units is possible.

1. Year 1Rotations in three research units, plus courses chosen across disciplines.
2. Year 2Thesis research begins in your chosen unit. You finish remaining course requirements and sit a qualifying examination, which leads to candidacy.
3. Years 3 to 5Thesis research continues until you submit a completed thesis for examination.

A credit-bearing course in professional and career development is a graduation requirement. Research and teaching are in English, and OIST offers free Japanese classes for those who want them.

Because you choose your lab only after arriving, the rotations matter more than the statement you send now. OIST publishes a list of faculty who are recruiting PhD students; check it before you write, since a rotation can only happen in a unit that is taking students.

Selection, from form to offer

There is no written entrance examination. Selection runs in three steps, all of them remote.

1. Shortlisting. The Admissions Committee reviews applications, and results are due in late December 2026.
2. The Admissions Workshop. Shortlisted applicants are invited to an online workshop held between 18 January and 7 February 2027. Attendance is compulsory. OIST’s FAQ says the process includes interviews with four faculty members.
3. Final decision. Results are announced in mid-February 2027.

Successful applicants then start on one of three dates: 1 May 2027, 1 September 2027 or 1 January 2028. OIST notes the dates may change, and that housing and flights are arranged about a month before enrolment.

The interviews come from faculty across fields, so expect questions from someone who works far from your own subject. A good preparation exercise is to explain your undergraduate research to a non-specialist in five minutes, then say what you would want to learn in each of your three rotations. Our guide on preparing for a video interview covers the practical side.

Putting the application together

Applications go through OIST’s online portal. Alongside the letters you upload:

• transcripts and diplomas as scanned PDFs (unofficial copies are fine; send a certificate of enrolment if you have not graduated, and an English explanation for transcripts in other languages)
• a statement of purpose on your research aims and why OIST suits you, within the length limit on the application page
• a CV in any standard format
• your English test score, if needed
• the photo page of your passport, or other government ID if you have no passport
• an ID photo taken in the last three months

The application fee is 5,000 yen and is not refundable. OIST does not offer fee waivers for personal financial hardship. Applicants who cannot pay because of international sanctions are told to contact OIST through its Contact Us page, giving “OIST PhD Program” as the reason.

The statement is short, so spend it on a problem rather than a biography. OIST is looking for people who will use the interdisciplinary setup, and a statement that names two or three units and explains what links them is more convincing than a list of achievements. For the wider process of choosing and applying for funded doctorates, see our guide to finding and applying for a funded PhD, and our advice on asking for a recommendation letter before you contact your referees.

All dates and figures here come from OIST’s PhD application page and student support page, checked 9 October 2026. Check both again before you submit, since OIST says the schedule may change.
