Canadian International School (CIS Tokyo) — IB PYP Only, Not a Full Continuum

Tokyo, Japan

A three-site school in Osaki and Nakameguro, blending the Canadian (Prince Edward Island) curriculum with IB PYP.

Researched by William Prep from published sources. Not yet verified by the school. — Last reviewed by William Prep: 2026-09-24

CIS Tokyo centres on Prince Edward Island's recognised Canadian curriculum, layered with IB PYP. It operates across an Osaki campus (Kindergarten and High School) and a Nakameguro campus (Elementary).

The IB Here Is PYP Only — Not a Full Continuum

The school's own site references IB PYP authorisation but makes no mention of MYP or the Diploma Programme. That means CIS Tokyo runs the Canadian curriculum as its backbone with IB PYP layered on in the early years — not a school that carries a student through to an IB Diploma at graduation. Worth not assuming "CIS" implies a full IB continuum here.

William Prep’s Analysis

For a family whose end goal is an IB Diploma, CIS Tokyo likely means a transfer to another school partway through — it is not built to carry a student all the way there. For a family oriented toward Canadian university admission instead, the PEI-recognised curriculum is arguably the bigger selling point, not a gap.

Fees: A Real First-Year Total of About ¥3.80M (Grade 1–5)

CIS Tokyo's own 2026-27 fee page lists two one-time charges: a ¥300,000 registration fee and a ¥600,000 building development fee (Grade 1–12 only). On top of that, an annual ¥250,000 building maintenance fee applies alongside grade-banded tuition (¥2,650,000 for Grade 1–5). Added together, a genuine first-year total comes to roughly ¥3,800,000. No application fee appears on this page.

University Entrance Eligibility in Japan

School-accreditation route	Yes (not independently confirmed)
Student-qualification route (IB, etc.)	No not publicly confirmedCIS Tokyo appears to offer IB PYP only, not the Diploma Programme, so the individual-credential route likely does not apply — but this was not directly confirmed this session.

The WASC (ACSWASC) reference comes from the school's own site, but the exact nature of that accreditation (full vs. candidate) was not confirmed this session. CIS Tokyo is centred on the Canadian (PEI) curriculum, with IB PYP as an enrichment layer rather than a full continuum.

What Makes This School Distinctive

A Prince Edward Island-recognised curriculum as the backbone

IB PYP is layered on top, but MYP and the Diploma Programme do not appear to be offered

The school's own site cites PEI recognition and IB PYP, with no mention of MYP or DP.

Families ultimately targeting the IB Diploma need to plan for a transfer partway through.

What Japanese Families Should Know

Who Might Find This School a Good Fit

Might suit — Families oriented toward Canadian university admission, or wanting IB PYP specifically for the early years

Might not suit — Families wanting a student to carry the IB continuum through to the Diploma at graduation

William Prep’s Analysis

What stood out in researching CIS Tokyo is that a name including "International" says nothing reliable about whether a school runs a full IB continuum. A Canadian-curriculum-first structure is a legitimate, distinct choice on its own terms — not a lesser version of an IB school. But how well it fits depends heavily on what a family is actually aiming for at graduation.

Questions to Ask the School

1.What does the path to graduation actually look like without an IB Diploma track? Is a transfer assumed?
Why this matters: Not confirmed this session.
2.Is the WASC (ACSWASC) status full accreditation or candidacy?
Why this matters: Not confirmed against WASC's own registry directly this session.
