01Tuition & Fees
Fees: Only 2024-25 Data Could Be Confirmed
The school's own site (marist. ac. jp/tuition-fees/) was checked in currently available public information, but the actual 2026-27 fee amounts are held in a separate downloadable document that wasn't retrieved. Third-party sources report 2024-25 figures (PYP Early Years ¥1,548,660, PYP Grade 1-5 ¥1,778,680, MYP Grade 6-10 ¥1,875,140, DP Grade 11-12 ¥1,883,620) — one to two years stale, and no application or registration fee amount was found at all.

University Entrance Eligibility in Japan
| School-accreditation route | Yes (not independently confirmed) |
| Student-qualification route (IB, etc.) | Yes |
WASC accreditation is based on third-party reporting, not confirmed against the registry directly in currently available public information. Independent of that, a student completing the full IB Diploma qualifies via the individual-credential route regardless.

04School Features
Not the Same School as "St. Mary's"
Some search results conflate MBIS with St. Mary's International School in Tokyo (a boys-only school founded by the Brothers of Christian Instruction). Despite the similar name, these are entirely separate institutions — different founding religious order, different city (Kobe vs. Tokyo), different admissions policy (MBIS coeducational, St. Mary's boys-only).
Key Point
Catholic-founded schools draw on multiple religious orders, and similarly-named schools turning up in different cities isn't unusual. Searching by name alone risks blending in information from an entirely different school by mistake. Making this distinction explicit was itself one of the goals of this profile.
What Makes This School Distinctive
WASC accreditation reportedly dating to 1972
Over 50 years of reported WASC accreditation history
Multiple third-party sources consistently report the 1972 date.
A strong signal of institutional stability for families weighing accreditation continuity.
