Finding true bilingual schools in Tokyo is a priority for many international families who want their children to grow up fluent in both English and Japanese. Tokyo's international school scene is one of the most mature in Asia, and while most schools teach primarily in English, a strong group of schools has built serious dual-language programmes where Japanese is far more than a token subject. This 2026 guide explains how bilingual education works in Tokyo, which schools deliver it best, and what fees and admissions look like for expat families.
How Bilingual Education Works in Tokyo
Tokyo's schools approach bilingualism in three broad ways. Immersion schools split the timetable between English and Japanese instruction, so children learn maths, science or humanities in both languages. English-medium international schools with strong Japanese programmes teach daily Japanese at native and non-native levels, often preparing students for Japanese qualifications alongside the IB or American diplomas. Finally, dual-credential schools allow students to graduate with both an international qualification and recognition within the Japanese system. The right model depends on how long you plan to stay in Japan and whether your child may join a Japanese university later.
Top International and Bilingual Schools in Tokyo for 2026
Nishimachi International School
Founded in 1949 in the heart of Azabu, Nishimachi is Tokyo's reference point for genuine bilingual education. Every student from kindergarten to grade 9 studies Japanese daily within an English-medium, inquiry-based programme, and the school's small size fosters an unusually tight community. Graduates leave with functional to native fluency in both languages.
The American School in Japan
ASIJ in Chofu is one of Asia's leading American curriculum schools, with a large campus, outstanding facilities and a Japanese language programme that runs from beginner to native-speaker tracks. Advanced Placement courses and exceptional university placement make it a favourite of families heading to US universities.
The British School in Tokyo
BST teaches the English National Curriculum through to A-Levels from its modern Azabudai Hills campus. Japanese is embedded across the primary years and offered to GCSE and beyond, and the school's central location suits families living in Minato and the embassy districts.
Tokyo International School
An IB World School offering the PYP and MYP with a well-structured Japanese language and culture programme. Its inquiry-driven approach and mid-sized community make it a strong option for families who want the IB pathway with meaningful Japanese integration.
St. Mary's International School
A boys' school in Setagaya with more than 70 years of history, offering the IB Diploma and a respected Japanese programme. Its combination of academic tradition, sport and brotherhood culture keeps it consistently in demand.
International School Fees in Tokyo
Tokyo sits at the premium end of Asian school fees. Expect annual tuition of roughly ¥2.0 to ¥2.6 million at bilingual and mid-sized international schools, and ¥2.8 to ¥3.6 million at the largest American, British and IB schools, plus one-off entrance fees of ¥300,000 to ¥860,000, building maintenance levies and bus fees. Many employers in Japan include school fees in expat packages, and schools are experienced in invoicing companies directly.
Admissions and Practical Tips
Tokyo admissions run earlier than much of Asia: applications for August entry open the previous autumn and rolling assessments begin from November. Schools ask for two years of reports, teacher references and age-appropriate English screening; bilingual programmes may also assess Japanese level to place children in the right track. Location matters enormously in a city of Tokyo's scale, so shortlist schools within a realistic commute of your neighbourhood, and remember that school buses often determine which areas are practical. If both parents work in central Tokyo, Minato, Shibuya and Setagaya offer the widest choice.
