OIST PhD Program 2027 in Okinawa, Japan

About

The Okinawa Institute of Science and Technology Graduate University (OIST) runs an interdisciplinary PhD program in science, taught and conducted in English. The program covers fields such as physics, chemistry, biology, neuroscience, mathematics, computer science and engineering. There are no departments, so students can work across subjects. OIST does not hold written entrance exams. Selection is based on your application file and online interviews.

OIST admits about 60 full-time PhD students each year, and all of them are fully funded through a Research Assistantship, whatever their nationality. You can apply with a bachelor’s degree. A master’s is not required. The first two years give broad training: you choose your thesis lab at the end of the first year and fix your thesis topic after a qualifying exam at the end of the second year. Students who enter with a STEM master’s need fewer course credits.

Host institution and country

OIST is a graduate university on the island of Okinawa, in the south of Japan. Its campus is in Onna village, on the west coast of the main island. Students live in the on-campus Campus Village for at least their first year. The university offers on-campus childcare, a health center and visa help from its student affairs team, which makes it easier to move to Japan with a family.

Financial benefits

• Full tuition, covered by the Research Assistantship
• Living support of about 2.6 million yen a year (taxable) in the first year, rising to about 3.6 million yen a year as you progress
• Subsidized on-campus housing: about 21,600 yen a month for a furnished single apartment, or 18,000 yen a month per person in a shared two-room apartment
• A one-way flight to Okinawa after your visa is issued, also for your spouse and children
• Reimbursement of the cost of shipping your belongings, up to a limit set by your country, plus a fixed transfer allowance for visa fees and local transport
• A separate budget for domestic and international research travel
• Student accident and liability insurance

Students are expected to study and research full time and may not take part-time jobs elsewhere. OIST encourages students to apply for external fellowships as well.

Eligibility criteria

• Applicants of any nationality
• A bachelor’s or master’s degree, or expected before your enrollment date

• A research interest that matches one or more OIST faculty members who have space for new PhD students

Required documents

All documents must be in English and uploaded as PDFs.

• Transcripts and diplomas for all your degrees (unofficial scans are accepted). If you have not graduated yet, a certificate of enrollment with your expected graduation date
• A statement of purpose of up to 800 words about your research goals and why OIST is a good fit
• A CV in any standard format
• Two to five recommendation letters from professors. Letters from lab members or postdocs are not accepted

How to apply

1. Read the OIST faculty list and the research units that match your interests.
2. Check that the faculty members you want to work with can take new PhD students. Strong applicants can be rejected if there is no space in their field.
3. Ask your referees early. They submit their letters through the portal, and you can only submit once at least two letters have arrived.
4. Complete the online application at graduateschool.oist.jp/apply. You can save your work and finish later.
5. Pay the non-refundable 5,000 yen application fee. Fee waivers are not offered for personal financial reasons.
6. Submit before 15 November 2026, 23:59 Japan Standard Time (UTC+9).

Selection process and timeline

• Late December 2026: shortlisting results are sent out.
• 18 January to 7 February 2027: shortlisted applicants attend the online Admissions Workshop. Attendance is required. You interview with four faculty members by video.
• Mid-February 2027: final offers are sent.
• You can then enroll on 1 May 2027, 1 September 2027 or 1 January 2028.

OIST does not give feedback on decisions. You may reapply the next year if your academic record has progressed. Dates may change, so check the official page.

Tips for a strong application

• Name specific OIST faculty in your statement of purpose and explain how your interests connect to their work.
• Choose referees who know your research well. A detailed letter from a professor counts more than a short one from a famous name.
• Show research experience, such as a thesis, a lab project or a publication, and say what you learned from it.
• Prepare for the interviews by reviewing the basics of your field and recent papers from the labs you named.
• Submit early so you have time to follow up on missing letters before the deadline.
