Yoyogi International School — Ends at Age 15, No High School Division

Tokyo, Japan

A small-class (max 16 students) IB PYP school across two Shibuya-ku campuses — Yoyogi and Jinnan.

Yoyogi International School runs across two Shibuya-ku campuses (Yoyogi, ages 4-6, and Jinnan, ages 6-15), with a maximum of 16 students per class. It's reportedly a fully authorised IB PYP school — but since it stops at age 15, it appears not to offer a high-school (DP) division.

A School That Ends at 15 — Plan for a Transfer

Similar in structure to Nishimachi (which ends at Grade 9), also researched in this project, Yoyogi International School serves only up to age 15. It's not a school that carries a student through the full IB continuum (PYP/MYP/DP) — a transfer is needed before reaching high school. The legacy directory's description ("Bilingual JP/EN own curriculum") also doesn't match what was actually confirmed here (an authorised IB PYP programme).

William Prep’s Analysis

A school that ends partway through adolescence isn't a flaw in itself — for families prioritizing careful, small-class early education, it could be a genuine strength. But choosing it on the assumption "my child can stay here through high school graduation" would mean having to replan later. Worth factoring in a transfer destination from the start.

Fees: A Real First-Year Total of About ¥3.82M (Early Years/Primary Years)

Yoyogi International School's own 2026-27 fee schedule lists three one-time charges: a ¥33,000 application fee, a ¥330,000 registration fee, and a ¥600,000 campus development and maintenance fee. On top of that, an annual ¥160,000 educational development fee applies alongside grade-banded tuition (¥2,700,000 for Early Years/Primary Years), for a genuine first-year total of roughly ¥3,823,000. The school explicitly states no sibling discounts are offered.

University Entrance Eligibility in Japan

School-accreditation route	No not publicly confirmedWhether Yoyogi International School holds any of the six MEXT-recognised accreditations was not confirmed this session.
Student-qualification route (IB, etc.)	No not publicly confirmedSince no high-school (DP) division appears to exist, a student cannot earn the IB Diploma through this school alone.

Yoyogi International School appears to be a PYP-only school for early years through early adolescence (to age 15), without a DP division. By the time university eligibility becomes relevant, a student would already have transferred elsewhere.

William Prep’s Analysis

Noticing the parallel with Nishimachi while researching Yoyogi International was a useful cross-check. A school "that ends partway through" can look like an outlier when researched in isolation — but researching across multiple schools reveals it's a recurring pattern, not a one-off.

Questions to Ask the School

1.Where do most graduates transfer to after finishing at age 15?
Why this matters: Not confirmed this session.
2.Are there plans to add MYP authorisation in the future?
