The British School in Tokyo

Tokyo's anchor British school, two campuses and roughly 1,400 students from sixty-plus nationalities, running the English National Curriculum through to IGCSE and IB. Rated Excellent across the board by ISI.

BST opened in 1989 and now runs primary at the new Azabudai Hills campus and secondary on the Showa Women's University grounds in Sangenjaya. The Showa campus gives older students unusually generous space for central Tokyo. CIS and COBIS-patron status sit alongside the ISI inspection rating.

Families describe a confident, traditional British rhythm with summer fete and Christmas fair anchors, an active parent association, and a consistent academic standard. The school is non-selective in principle but holds a strong reputation for outcomes and pastoral care. The fit is families committed to a UK-track education in central Tokyo and comfortable with a sizeable peer group rather than a boutique setting. The current principal is Ian Clayton.

• Treated as one of Tokyo's most-established international schools alongside ASIJ, Yokohama International School and Saint Mary's. Independent Schools Inspectorate rated the school "Excellent" across all eight categories.
• Two-campus model: Early Years and Primary at the new Azabudai Hills campus, Years 7-13 at the Showa campus. The Azabudai move repositioned the school squarely in central Tokyo.
• Demographic mix has shifted. Long-term Tokyo families and bicultural households now outnumber traditional 3-to-5-year British expat assignments. One parent on the International Schools Database flagged that many teachers are not native English speakers and questioned how the school markets that mix; the school responded saying around 95% of teaching staff come from English-speaking countries.
• Recent leavers go to Cambridge, Imperial, UCL, Tokyo and Keio universities, plus US and Canadian destinations.
• BST is also a recruitment-tier reference point: a senior leader moving to Kellett Hong Kong was described in teacher-side threads as "highly regarded internationally" because of their BST background.
• Direct parent-review pool online is small. The single ISD review skews lower because of the native-speaker concern; broader editorial and admissions-side coverage is consistently positive.
