OIS reportedly opened in 2003 as an international preschool in Naha, later expanding through high school. IB authorisation proceeded in stages — PYP (2011) → MYP (2016) → DP (2020) — reportedly making this Okinawa's first and only full IB continuum school. It operates across two sites: a Naha campus and a Nanjo campus (Tamagusuku).

02Admissions
IBDP or ILA Determines the Eligibility Route That Follows
OIS's high school reportedly offers two tracks: IBDP (leading to the IB Diploma) and ILA (International Liberal Arts, which does not). The two tracks even carry different tuition (IBDP ¥1,738,900/yr, ILA ¥1,510,000/yr) — the assumption "attending OIS means earning the IB Diploma" doesn't hold across the board.
Key Point
This is a good example of how a school's institutional status ("full IB continuum school") and what any individual student actually walks away with can diverge. A family counting on the individual-credential (IB Diploma) route to Japanese university eligibility needs to understand that the ILA track doesn't provide it, before deciding which track to pursue.
| Cycle | 未確認 not publicly confirmed |
University Entrance Eligibility in Japan
| School-accreditation route | No not publicly confirmedWhether OIS holds any of the six MEXT-recognised accreditations is not publicly confirmed. |
| Student-qualification route (IB, etc.) | Yes |
Whether OIS itself holds a MEXT-recognised accreditation is not publicly confirmed. A student on the high-school ILA (International Liberal Arts) track, rather than IBDP, would not earn the IB Diploma and so the individual-credential route would not apply to them. A student completing the full IB Diploma qualifies via that route regardless of the school's own accreditation status.
What Japanese Families Should Know
Questions to Ask the School
1.What are the actual university outcomes for students on the ILA track?
Why this matters: Public information does not establish this clearly; confirm it directly with the school.
2.When and how is the choice between IBDP and ILA made?
Why this matters: Public information does not establish this clearly; confirm it directly with the school.

What Makes This School Distinctive
Two distinct high-school tracks (IBDP / ILA)
A choice between the IB-Diploma-granting IBDP and the non-IB ILA
The two tracks reportedly carry different tuition, signaling they function as genuinely separate programmes.
