Hiroo Gakuen International Course — Not IB, Not A-Levels: An English-Intensive Track Inside a Regular Japanese School

Tokyo, Japan

The name suggests an overseas curriculum, but it's actually an English-intensive track inside Japan's standard Article 1 school system.

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

Hiroo Gakuen is a private junior/senior high school in Minami-Azabu, Minato-ku. It was founded in 1918 as Junshin Girls' School by Kinuko Itagaki, and became coeducational under its current name in 2007. Its "International Course" sits inside that same Article 1 curriculum, split into two English-intensity tracks — Advanced Group (AG) and Standard Group (SG).

Why the Name "International Course" Is Easy to Misread

According to the school's own site, the Advanced Group (AG) is for students who already have English proficiency and studies core subjects in English; the Standard Group (SG) is for students building English proficiency gradually. Neither is an independent overseas curriculum like IB or A-Levels — both run inside the regular Article 1 curriculum. High-schoolers get SAT/TOEFL preparation and AP courses, clearly aimed at overseas university applications.

William Prep’s Analysis

The name "International Course" might suggest the same category as an overseas-style school like ASIJ or ISAK, but institutionally it's a different thing entirely. Because Hiroo Gakuen is an Article 1 school, graduating confers domestic university eligibility automatically — a fundamentally different mechanism from a school that depends on WASC accreditation or an IB Diploma. It's a useful illustration of just how much the phrase "international school" can actually cover.

Fees: Only Partial, Third-Party Figures So Far

Search results report an entrance fee of ¥388,000, monthly tuition of ¥71,350, and an annual education enrichment fee of ¥300,000 (AG) or ¥180,000 (SG). None of this was confirmed against the school's own published fee schedule this session — it's third-party reporting. Specific amounts for facilities, heating/cooling and other listed fees weren't available either, so a first-year total has deliberately not been calculated here.

University Entrance Eligibility in Japan

School-accreditation route	Yes
Student-qualification route (IB, etc.)	No not publicly confirmedHiroo Gakuen does not appear to offer IB, A-Levels, or another curriculum that would trigger the individual-credential eligibility route (based on what was confirmed this session).

Because Hiroo Gakuen is an Article 1 school, domestic university eligibility is automatic on graduation for every student, including those in the International Course — a fundamentally different mechanism from schools like ASIJ or ISAK that depend on WASC accreditation or an IB Diploma. Applications to overseas universities would use SAT/TOEFL/AP scores instead, which is a separate question from Japanese university eligibility.

What Makes This School Distinctive

Automatic domestic eligibility, plus dedicated overseas-application preparation

Graduation confers automatic domestic university eligibility, while SAT/TOEFL/AP preparation is built in for overseas applications too

Stated on the school's own International Course page — AP courses and overseas application guidance are both mentioned.

A structural safety net for families who want to keep domestic options open while still preparing for overseas applications.

University Pathways

Hiroo Gakuen is widely known for its overseas university placement record, but the school's own outcomes data was not directly consulted this session. Many third-party write-ups appear to treat offer counts as if they were matriculation destinations without distinguishing the two — this profile deliberately avoids repeating that conflation.

Actual university matriculation destinations (by enrolled student, not by offer received) were not confirmed this session.

What Japanese Families Should Know

Who Might Find This School a Good Fit

Might suit — Students wanting to keep the domestic university path open while also preparing for overseas applications

Might not suit — Students specifically wanting to earn an internationally-recognised independent qualification like the IB Diploma or A-Levels

William Prep’s Analysis

The most important part of researching Hiroo Gakuen was being precise about what "International Course" actually means here. It gets discussed in the same breath as schools like ASIJ or ISAK, but the mechanism behind Japanese university eligibility is fundamentally different — an Article 1 school's automatic domestic eligibility versus a WASC-accreditation or IB-Diploma route. Comparing schools without understanding that difference risks lining up options that aren't actually comparable on the terms a family assumes.

Questions to Ask the School

1.What are the specific admissions criteria for AG vs. SG, and can a student move between tracks later?
Why this matters: Not confirmed this session.
2.Could you provide the complete fee schedule — including facilities, heating/cooling, PTA fees — broken down by grade?
Why this matters: Only partial, third-party figures were available this session — not the school's own published fee schedule.
3.Where did recent graduates actually matriculate — by enrolled student, not offers received — broken down by domestic vs. overseas?
Why this matters: Hiroo Gakuen is known for overseas placement, but many write-ups blur offers and matriculations together — the actual enrolled-student data wasn't confirmed this session.
