For expat families settling in Tokyo, bilingual education is one of the most valuable gifts you can give a child. The city offers a unique mix of full-immersion Japanese-English schools and international schools with strong Japanese-as-a-second-language tracks. The bilingual international schools in Tokyo for 2026 reflect a global student body, modern campuses and a deep commitment to keeping both languages at academic level — an outcome few cities can match.
Approaches to Bilingualism in Tokyo
Bilingual programmes in Tokyo broadly fall into three categories. The first is dual-language immersion, where instruction is split roughly 50/50 between Japanese and English from early years onward. The second is English-medium with strong daily Japanese as a Foreign Language (JFL) classes, plus cultural immersion activities. The third is the IB or British international model with optional advanced Japanese tracks for students aiming at Japanese university or maintaining family-language fluency. Each model produces different outcomes, so the right choice depends on whether your family expects to remain in Japan long-term or to move on.

The schools below are listed on International School Advisor with verified profiles. They are recognised for their bilingual programmes, language support and integration of Japanese culture.
Aoba-Japan International School
Aoba-Japan International School is fully IB-authorised across PYP, MYP and Diploma. It runs a structured bilingual stream alongside its international track, with Japanese taught daily as either a native or additional language. The Meguro and Hikarigaoka campuses make it accessible to families across central and west Tokyo.
Seisen International School
An all-girls Catholic IB school in Setagaya, Seisen International School teaches the IB continuum and offers Japanese language across all proficiency levels. Boys are welcomed in the Montessori kindergarten. The community is famously close-knit and well integrated with local Japanese culture.
Tokyo International School
Tokyo International School in Minato is a long-established IB school, popular with diplomatic families. Its Japanese language programme spans complete beginners to native-speaker pathways, and the school's Minami-Azabu location is convenient for the embassy district.
Canadian International School Tokyo
Canadian International School Tokyo follows a Canadian curriculum framework with strong daily Japanese instruction. It is known for warm pastoral care, smaller class sizes and a commitment to community integration in Shinagawa.
Makuhari International School
Makuhari International School sits in Chiba, accessible from east Tokyo and Narita. It teaches the IB PYP and MYP with explicit dual-language outcomes, and is a strong fit for families based in the Bayside or commuting from Chiba.
Bilingual Programme Fees
Bilingual international schools in Tokyo are among the more expensive in the city, reflecting the cost of running two parallel language faculties. Typical 2026 ranges:
- Early years and primary: ¥2.0M to ¥2.8M per year.
- Lower secondary: ¥2.5M to ¥3.0M per year.
- IB Diploma years: ¥2.7M to ¥3.5M per year.
Add ¥200,000 to ¥500,000 for facility fees, a building fund (often required at entry) and an entrance fee at most schools. Lunch, bus and trips typically add ¥250,000 to ¥500,000 per year.
Choosing the Right Bilingual Model
Three questions help families decide. First, will your child remain in Japan for university? If yes, lean toward dual-immersion or schools with native-track Japanese. Second, what is your child's current Japanese exposure? Beginners benefit from English-medium schools with strong JFL support; native speakers thrive in dual-immersion. Third, how mobile is your family? Highly mobile families may prefer the IB pathway, which transfers internationally; long-term residents can commit to deeper immersion.
Admissions and Timing
Most bilingual programmes assess Japanese proficiency at entry, particularly for years above kindergarten. Expect English assessments, parent interviews and prior school reports. Apply six to nine months before your intended start date — places in dual-immersion streams are limited and fill earliest. Coordinate with your visa timeline, as schools often require proof of resident status before issuing a final offer.
