Top 20 IGCSE Schools in Tokyo

Tokyo has a strong cluster of international schools. For IGCSE families, the top ranking factors are subject breadth, teacher specialism, and whether the school has consistent exam technique routines (mocks, past papers, feedback cycles).

What to ask for (IGCSE outcomes + evidence)

• Published or shareable outcomes (subject-by-subject if possible)
• Number of entries and cohort size
• How the school supports exam-year students (revision plans, intervention)
