Schools
What are the best international schools in Tokyo for expat families?
Tokyo's established international schools include The American School in Japan (ASIJ), St. Mary's International (boys) and Seisen International (girls), The British School in Tokyo, Nishimachi, and Aoba-Japan (full IB continuum). Japan has no public school inspectorate, so quality rests on international accreditation (CIS/WASC/NEASC) — BrightKey caps Tokyo tiering at A and flags, rather than estimates, the fees and results many Tokyo schools don't publish.
Choice often comes down to curriculum (American at ASIJ, British at BST, full IB at Aoba) and practicalities — single-sex vs co-ed, campus location across Tokyo's wards, and waitlists, which can be long for the most established schools.
Many Tokyo international schools don't publish fees or exam results publicly; we flag that gap rather than guess. Verify current figures directly with each school.
