Choosing an international school in Tokyo in 2026 means navigating one of the most diverse and competitive expat school landscapes in Asia. Tokyo offers full English-medium IB schools, British and American flagships, French and German national-system schools, and a smaller selection of bilingual Japanese-English programmes. With waiting lists stretching well over a year at the top-tier schools, families need to start the process the moment a Tokyo posting becomes likely. This guide walks through curricula, top schools, fees in JPY, neighbourhood logic, and how to time an application that actually wins a place.
Curricula available in Tokyo
The main pathways for expat children in Tokyo are:
- International Baccalaureate: the most common system at multi-national families' first-choice schools (PYP, MYP and DP available at most top IB schools).
- American (US curriculum + AP): The American School in Japan (ASIJ) remains the benchmark.
- British (EYFS, National Curriculum, IGCSE, A Level): The British School in Tokyo, and a handful of smaller British schools.
- French (AEFE): Lycee Francais International de Tokyo.
- German: Deutsche Schule Tokyo Yokohama.
- Bilingual Japanese-English: a small but growing segment, mainly at the primary level.
If your child may move countries again within five years, IB or American AP gives the cleanest transferability. For UK-bound families, IGCSE + A Level via The British School in Tokyo is the natural fit.

International school fees in Tokyo (2026)
Fees are quoted in Japanese yen (JPY). Realistic 2026 annual tuition at the leading Tokyo international schools:
- Primary (Years 1 to 6): JPY 2,000,000 to JPY 3,000,000.
- Middle School: JPY 2,200,000 to JPY 3,200,000.
- High School / IBDP: JPY 2,400,000 to JPY 3,400,000.
The biggest hidden cost in Tokyo is the entrance / facility fee: a one-off JPY 1,000,000 to JPY 3,000,000 paid at first enrolment. Some schools also charge an annual building maintenance fee on top of tuition. Bus services in Tokyo are highly distance-sensitive and easily reach JPY 200,000 to JPY 400,000 per year. Plan another 15 to 20 per cent on top of headline tuition for trips, uniforms and lunches.
Where do international schools cluster?
Tokyo's school geography matters because trains and buses can turn a 5 km journey into a one-hour commute:
- Minato / Roppongi / Hiroo: the traditional expat heartland. Tokyo International School, Aoba Japan (Hikarigaoka), Seisen, St. Mary's are all within reach.
- Shibuya: The British School in Tokyo (Showa campus). Premium housing.
- Chofu (west): The American School in Japan. Long commute from central Tokyo unless you live in suburban Tokyo or rely on the school bus.
- Koto / east: K. International School. Less expat-dense but improving rapidly.
Choose the school first. House-hunt afterwards within a 30-minute zone of that school's bus route.
Admissions timing for 2026 entry
Top international schools in Tokyo run formal admissions cycles for August start dates, with the bulk of decisions issued in February and March of the same year. Mid-year entries (January) are possible at most schools but with fewer available places.
- Register interest 12 to 18 months ahead at the most competitive schools (ASIJ, BST, St. Mary's, Tokyo International).
- Submit full applications 6 to 9 months before target start date.
- Most schools require previous school reports (two years), references, a parent interview and a child assessment.
- If you are applying mid-year, ask explicitly whether the school can guarantee continuity into the next academic year.

Frequently asked questions
Can expat children attend Japanese public schools?
Yes, in principle, but instruction is entirely in Japanese and curriculum integration with international systems is limited. Most expat families opt for international schools.
How early should I apply to international schools in Tokyo?
For the most competitive schools (ASIJ, BST, Tokyo International, St. Mary's), 12 to 18 months ahead. For other schools, 6 to 9 months is usually sufficient.
Are there bilingual Japanese-English international schools in Tokyo?
Yes, a growing handful at primary level. Aoba-Japan Bilingual Preschool, Laurus International School of Science and a few Montessori bilingual options exist, but secondary bilingual provision is limited.
