Trade-offs
- !Does NOT publish AP results or university-placement data — outcomes cannot be independently verified
- !Explicitly offers no scholarships or financial aid for new applicants, with high all-in costs
- !English-fluency requirement for at least one parent narrows the applicant pool
- !Day school only — no boarding
- !Public detail on EAL/English-language support could not be confirmed
- !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)
Best Fit For
- • Expatriate and internationally-mobile families in Tokyo seeking a U.S. college-prep track

- • Families prioritising authentic English–Japanese bilingualism in the early/elementary/middle years
- • Families based long-term in central Tokyo seeking a small, community-oriented school
- • Children who will continue to a separate high school (international in Tokyo or abroad)

University Placement
School-reported · not independently verified
Not public. No university-placement, college-matriculation, or AP results data is published on ASIJ's public website (consistent with the norm among Tokyo international schools).
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).
