What “best” means here
This is not a paid ranking — no school can buy a position. Order follows our transparent tier: in markets with a graded public inspectorate (e.g. Dubai's KHDA), by the verifiable inspection band; where there is none, by accreditation depth and curriculum authorisation, capped at A. Within a tier, schools are listed alphabetically. School-reported university placement is always flagged and never tiered.

A long-established (1976), IB-aligned Tokyo school with a distinctive entrepreneurship/innovation identity and a Japan-heavy student body — strong on continuity, with MYP authorization the main thing to verify.
A long-established, academically elite IB school in central Tokyo with exceptional, consistently published Diploma results (42.0/45 in 2025) and full CIS accreditation — but a deliberately high-bar English-admissions policy with no language support above Grade 7.
A small, prestigious, central-Tokyo bilingual day school (K–9) with 75+ years of heritage and genuine dual WASC + CIS accreditation — distinctive for a deep, leveled Japanese-language programme, but note it ends at Grade 9, so high-school placement must be planned separately.
A well-established Catholic, girls'-school (co-ed kindergarten) IB continuum school in Setagaya, with strong dual CIS + NEASC accreditation and a 60+ year history.
A long-lineage Catholic, all-boys international school in Setagaya — one of Tokyo's most established and selectively accredited (CIS + WASC) IB Diploma providers.
Tokyo's flagship American-curriculum, WASC-accredited, non-profit co-ed day school (est. 1902), serving ~1,734 students ages 3–18 across two campuses with an AP-based college-prep programme.
A small, well-established, technology-forward IB World School (PYP + MYP authorized, DP in candidacy) in central Tokyo — strong on accreditation and language support, but the upper school is new and unproven.
A long-established, premium British-curriculum school — the largest of its kind in Japan — with strong published exam results, now transitioning its sixth form from A-Levels to the IB Diploma.
