04School Features
"First in Japan" Plus Three Decades of Actual Track Record
"Runs the full IB continuum" alone doesn't tell you how long a school has actually been doing it, and that gap matters for a family weighing school choice.
Key Point
Even within the same "full IB continuum school" category, how long a school has held that status and how many graduating cohorts it's actually produced varies enormously. Treating a school with OIS's track record the same as one that was just authorised isn't a fair comparison.
What Makes This School Distinctive

Founded 1991, reportedly the first school in Japan to run all three IB programmes
Multiple third-party sources consistently report this "first in Japan" standing.
A real advantage for families prioritizing programme maturity and accumulated institutional know-how.
Who Might Find This School a Good Fit
