FAQs
Do I need to secure prior professor approval before submitting my OIST PhD application?

Can I apply for the OIST PhD program with only a Bachelor’s degree?
Yes. Candidates holding a 4-year Bachelor’s degree (or who expect to complete one prior to enrollment) are fully eligible to apply directly for the 5-year integrated PhD program without needing a Master’s degree.
Is living in Okinawa expensive for international students on the OIST stipend?

Focus heavily on interdisciplinary synergy—explain how combining techniques from at least two different research units at OIST can help solve your specific scientific problem. Highlighting cross-disciplinary curiosity aligns directly with OIST’s core mission!
