Trade-offs
- !Ends at Grade 9 — no high school; families must arrange a separate high-school transition (Tokyo or overseas)
- !No IB or Cambridge programme offered (no published authorisation)
- !No published EAL/ESL (English-support) programme on public pages — may challenge non-native-English entrants, especially at older grades
- !Small size means narrower extracurricular/specialist breadth than larger K–12 campuses
- !No published university-placement data (structurally — the school is K–9)
- !DP is only at candidate stage, not authorized — TIS cannot yet be relied upon as a full IB Diploma school
- !The upper school is brand new (Grade 11 only since 2025) — no published graduation/placement track record exists
- !No public academic results — no IB scores or university-destination data
- !Official materials contain internal inconsistencies on grade range (K-8 vs K-11 vs K-12)
- !Premium fees with a recent sharp increase, against an as-yet-unproven senior school

University Placement
School-reported · not independently verified
School-reported, unverified: the homepage cites '100% of graduates complete higher education.' Treat as a school-reported marketing claim — structurally limited because Nishimachi ends at Grade 9 (graduates proceed to separate high schools before any university placement).
Not public. As the upper school (G11/G12) and DP are newly established, no graduating-cohort outcomes exist yet.
