Nagoya International School (NIS) — JCIS Membership Is Not an Accreditation

Aichi, Japan

Founded 1964 in Nagoya's Moriyama-ku — one of the flagship international schools of the Chubu region, running the full IB continuum.

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

NIS opened in 1964 and reportedly moved to its current Moriyama campus in 1968. It runs the full IB continuum (PYP/MYP/DP) and is a member of JCIS (the Japan Council of International Schools).

JCIS Membership Is Not the Same Thing as Accreditation

NIS is reportedly a JCIS member — but JCIS is a collaborative association between schools, distinct from the six MEXT-recognised accreditors (WASC, CIS, ACSI, NEASC, Cognia, COBIS). JCIS membership on its own does not confirm the school-accreditation route to Japanese university eligibility.

William Prep’s Analysis

This is a textbook example of the problem with collapsing "accreditation," "membership," and "brand licence" into a single field, which the legacy directory did. Whether NIS itself holds one of the six MEXT-recognised accreditations wasn't confirmed this session — and that gap matters if a family is counting on the school-accreditation route rather than the individual IB Diploma route.

Fees: A Real First-Year Total of About ¥4.00M (Grade 1–5)

NIS's own 2026-27 fee schedule lists two one-time charges: a ¥50,000 application fee and a ¥1,000,000 registration fee. On top of that, an annual ¥250,000 campus development fee applies alongside grade-banded tuition (¥2,700,000 for Grade 1–5). Added together, a genuine first-year total comes to roughly ¥4,000,000. That ¥1,000,000 registration fee runs on the higher end among the schools researched this batch.

University Entrance Eligibility in Japan

School-accreditation route	No not publicly confirmedWhether NIS holds any of the six MEXT-recognised accreditations was not confirmed this session. The school is reported as a JCIS member — but JCIS is a membership association, not one of the six accreditors, and membership alone does not confer eligibility.
Student-qualification route (IB, etc.)	Yes

Whether NIS itself holds a MEXT-recognised accreditation was not confirmed this session. A student completing the full IB Diploma qualifies via the individual-credential route regardless.

What Makes This School Distinctive

A long-established anchor of international education in the Chubu region

Founded 1964, with over six decades of operating history

Reportedly operating from the same Moriyama site continuously since the 1968 move.

A meaningful signal of institutional stability for families in the Nagoya area weighing long-term continuity.

What Japanese Families Should Know

Who Might Find This School a Good Fit

Might suit — Families planning around the individual IB Diploma eligibility route

Might not suit — Families planning around the school's own institutional accreditation (WASC etc.) — not confirmed this session

William Prep’s Analysis

Researching NIS reinforced a principle worth restating plainly: belonging to an association and that association conferring university eligibility are two entirely different claims. A JCIS mention is useful evidence of a school's standing in the community — it just isn't evidence of an eligibility route on its own.

Questions to Ask the School

1.Does NIS itself hold a WASC or other MEXT-recognised accreditation?
Why this matters: Not confirmed this session — distinct from JCIS membership.
2.What is the actual source for the reported 85%+ full-Diploma completion rate — NIS itself, or a third party?
Why this matters: Based only on search aggregation — an NIS-published results page wasn't consulted this session.
