Choosing a bilingual school in Tokyo is one of the most practical decisions an expat family can make. With English and Japanese fluency rapidly becoming the baseline for university entry and future employment in Asia, parents are looking for schools that deliver both languages at mother-tongue level. This 2026 guide walks you through how bilingual education works in Tokyo, the main programme models, top schools with verified profiles, realistic fee ranges and how to secure a place.
Why bilingual education matters in Tokyo
Japan is still a country where English fluency is rare outside international business circles, which makes bilingual schools one of the most effective bridges between the expat community and Japanese society. Families on multi-year postings see it as a pragmatic investment: children leave Tokyo biliterate, culturally comfortable in both worlds and better positioned for Japanese, international and global university pathways.
The second driver is portability. A bilingual student who has kept up Japanese for ten years carries a skill no exam can replicate. Whether the next posting is Singapore, London or San Francisco, the language stays.
Main bilingual programme models in Tokyo
Full dual-language immersion
Roughly 50 percent of the day in English, 50 percent in Japanese, with core subjects taught in both languages depending on the year group. Used by a handful of primary schools aimed at families committed to long-term biliteracy.
International curriculum with structured Japanese
Primary instruction in English following an international framework (IB PYP, Common Core or a British-style curriculum), with daily Japanese classes differentiated between native speakers and learners. This is the most common model in Tokyo international schools.
Japanese national curriculum with English enhancement
Follows the Japanese national curriculum with English taught daily at a high standard, sometimes from native teachers. Suitable for families planning to stay in Japan long-term or whose children will transition into Japanese universities.
Continuum schools (Pre-K to Grade 12)
Schools that keep the same bilingual philosophy from kindergarten through graduation. These make the biggest difference: bilingualism compounds only when the pathway is uninterrupted.
Top international schools in Tokyo
St. Mary's International School
One of the oldest international schools in Tokyo, founded in 1954 by the Christian Brothers. An all-boys school offering the IB Diploma in senior years with a structured Japanese language programme running from elementary through high school. Strong reputation for university placement in North America and Europe.
Nishimachi International School
Co-educational school serving Pre-K through Grade 9 in the Azabu neighbourhood. Known for its structured English-Japanese bilingual programme, with Japanese taught daily at differentiated levels. A popular choice for families who want their children to leave Tokyo biliterate before transitioning to a senior school.
Tokyo International School
A full IB continuum school (Primary Years Programme, Middle Years Programme and Diploma). Small class sizes and a multicultural student body with more than forty nationalities represented. Located in Minato-ku with excellent transport links to Roppongi and Azabu.
Canadian International School Tokyo
Teaches the Ontario curriculum with Canadian-certified teachers, leading to the Ontario Secondary School Diploma. Daily Japanese classes are integrated into the schedule from kindergarten onward. A good choice for Canadian families and those targeting North American universities.
Shinagawa International School
Based in south-central Tokyo with easy access to the JR Yamanote line, this school offers a dual-language curriculum from early years through middle school. The bilingual model keeps instruction balanced between English and Japanese at every year group.
Tokyo neighbourhoods for international families
The most popular areas for families with children at international schools are Azabu, Hiroo, Minato-ku and parts of Setagaya. These neighbourhoods combine proximity to schools, embassies and international supermarkets with short commutes to Otemachi and Marunouchi. Rental housing aimed at expats tends to cluster here, and many landlords are used to short-term corporate leases.
For families on a tighter budget or who prioritise green space, Setagaya and Meguro offer larger apartments and houses at lower per-square-metre rates, with a 20 to 35 minute commute to the main school campuses.
Fees to expect in 2026
Tokyo international school fees are generally lower than equivalents in Singapore or Hong Kong, but the gap has closed over the last five years. Typical ranges per year:
- Early years (Pre-K / Kindergarten): JPY 1,800,000 to JPY 2,400,000
- Elementary (Grades 1-5): JPY 2,200,000 to JPY 2,800,000
- Middle school (Grades 6-8): JPY 2,500,000 to JPY 3,100,000
- High school (Grades 9-12): JPY 2,800,000 to JPY 3,500,000
On top of tuition, expect one-off registration fees (JPY 30,000 to JPY 80,000), a capital facilities fee (JPY 300,000 to JPY 1,000,000 at some schools), school bus (JPY 300,000 to JPY 450,000), and extracurricular activities and lunch programmes (JPY 200,000 to JPY 400,000). Sibling discounts of 5 to 10 percent are common from the second child.
Admissions: how and when to apply
Most Tokyo international schools operate rolling admissions but fill popular year groups (Pre-K, Grade 1, Grade 6 and Grade 9) early. Application steps families typically follow:
- Visit or attend an open day 9 to 12 months before intended start.
- Submit application with school reports, reference letters and, where required, a language proficiency assessment.
- Attend an age-appropriate interview or assessment day.
- Receive an offer and pay the deposit within 2 to 4 weeks.
- Settle visa, housing and transport arrangements before the August start.
For families relocating mid-year, waiting lists are common but spaces do open in January and September.
Practical tips from families already in Tokyo
- Visit in person when possible. The feel of a Tokyo school differs sharply between campuses, and virtual tours miss the community culture.
- Ask how Japanese is differentiated. A daily Japanese class is meaningless if the proficiency range in a classroom is too wide.
- Check senior leaver destinations over three years, not one. A strong IB programme should place graduates in Japan, the US, Canada, the UK and Australia.
- Look at the staff turnover rate. International schools with stable faculty produce more consistent bilingual outcomes.
- Verify the school bus network before signing a lease. A wrong neighbourhood decision can add two hours to a child's commute each day.

FAQ
Do bilingual schools in Tokyo accept children who do not speak Japanese?
Yes. Most international schools with bilingual programmes differentiate Japanese instruction between native speakers and beginners. Children joining without Japanese are integrated with dedicated teachers and catch up within one to two academic years in most cases.
How do Tokyo international school fees compare with Singapore or Hong Kong?
Tokyo fees are generally 10 to 25 percent lower than Singapore and Hong Kong equivalents for similar curricula, though capital levies and enrolment fees can narrow the gap. Budget JPY 3,000,000 to JPY 4,500,000 per year at the most established schools for secondary stages.
Which Tokyo neighbourhoods are best for international school access?
Azabu, Hiroo and Minato-ku offer the shortest commutes to most international schools and the densest expat housing market. Setagaya and Meguro are better value and still within reasonable commuting distance.
