With increasing globalization, a growing number of families are considering sending their children to international schools. However, many have questions and concerns, such as "How are they different from regular local schools?", "What are the tuition fees?", and "Will my child still be able to attend a Japanese university?"
This article provides a comprehensive guide to everything you need to know when considering an international school, from its definition and differences from preschools to current tuition costs, benefits, and drawbacks.
1. What is an International School? Definition and Legal Status
An international school is an educational institution that primarily serves children of foreign nationals, offering an international curriculum. In recent years, however, more schools have begun accepting students of Japanese nationality as well.
Legal Status in Japan
Most international schools are not classified as "Article 1 schools" (the standard elementary, junior high, and high schools defined under Article 1 of Japan's School Education Act). Instead, they are legally categorized as "miscellaneous schools" (kakushu gakkou) or are "unaccredited."
- Article 1 Schools: Follow the national curriculum set by the Japanese Ministry of Education (e.g., public and private local schools).
- Miscellaneous/Unaccredited Schools: Operate with their own unique curricula.
Important Note: Because they are not Article 1 schools, graduation from most international schools is not, in principle, recognized as fulfilling Japan's compulsory education requirements. Transferring to a public school or applying to a Japanese university may require graduation from an accredited school (e.g., by WASC, CIS, ACSI) or passing the high school equivalency examination.
2. International School vs. Preschool: What's the Difference?
The difference between an international school and a "preschool," which are often confused, lies in the target age group and educational purpose.
Features | International School | Preschool |
Target Age | Elementary to High School (K-12) | Ages 0-6 (Preschoolers) |
Primary Purpose | Academic growth, university preparation, character development | English immersion, cross-cultural experience, childcare |
Curriculum | IB (International Baccalaureate), Cambridge, AP, etc. | English learning through play, early childhood education |
Future Pathways | Overseas universities, international departments of Japanese universities, etc. | International school or a Japanese elementary school |
A preschool is essentially a "daycare or kindergarten in an English-speaking environment." Transitioning from a preschool to the elementary division of an international school typically requires a separate admissions process, which often includes an assessment of the child's English ability and a parent interview.
3. Comparison with Mainstream Japanese Schools (Language, Curriculum, Tuition)
This table summarizes the key differences between mainstream Japanese schools (Article 1 schools) and international schools.
Item | Mainstream Japanese Schools (Public/Private) | International School |
Language of Instruction | Japanese | English (some schools offer Japanese classes) |
Educational Approach | Based on the national curriculum set by MEXT | Inquiry-based learning, emphasis on critical thinking |
Textbooks | Government-approved textbooks | International textbooks, PCs/tablets, proprietary materials |
School Year | Starts in April, ends in March | Starts in August/September, ends in June (Western standard) |
Annual Tuition | Public: Free (only fees for lunch, etc.) | Approx. ¥2,000,000 - ¥4,000,000 (+ building fees, donations) |

4. Three Key Benefits of Attending an International School
① Acquisition of Practical English Proficiency
Students don't just learn English as a subject; they learn subjects like math, science, and history in English. This fosters Cognitive Academic Language Proficiency (CALP), the ability to use language in academic contexts, similar to a native speaker.
② Fostering Inquiry and a Global Perspective
The focus is on inquiry-based learning, which encourages students to ask "why?" rather than simply memorizing correct answers. Discussing topics with friends from diverse national backgrounds helps cultivate respect for diversity and the ability to logically articulate one's own opinions.
③ A Passport to Universities Worldwide
By earning an internationally recognized diploma (see below), students become eligible to apply to universities around the world. High-achieving students may also have opportunities to receive scholarships or preferential treatment in admissions from overseas universities.
5. Drawbacks and Risks to Consider
To avoid any regrets after enrollment, it's important to understand the following potential drawbacks.
- Significant Financial Burden
Beyond tuition, costs can include application fees, building maintenance fees, school bus transportation, donations, and overseas school trips. It's not uncommon for the total annual cost to reach ¥3 to ¥5 million.
- Challenges in Maintaining Japanese Proficiency
Due to the immersive English environment, students may fall behind their grade level in Japanese reading and writing without dedicated support at home. This can lead to a risk of "semilingualism" (or double-limited), where proficiency is not fully developed in either language.
- Difficulty Transferring Back to "Article 1" Schools
If a student wishes to transfer to a local Japanese public or private school mid-stream, they may struggle to adapt due to differences in curriculum and academic pacing.
6. Admission Requirements and Post-Graduation Pathways
What's Required for Admission
- Child's English Proficiency: Higher levels of English are required for older grade levels.
- Parent's English Proficiency: As school communications and parent-teacher conferences are conducted in English, parents' language skills are often part of the assessment.
- Aptitude Tests and Interviews: Admissions decisions are based not only on academic ability but also on whether the family's educational philosophy aligns with that of the school.
Graduation Qualifications and Pathways
Earning a diploma from a major international curriculum opens up various pathways.
- International Baccalaureate (IB): The most globally recognized program.
- Cambridge International Curriculum (A-Levels, etc.): A British system known for its academic specialization.
- WASC / CIS / ACSI Accreditation: Graduating from a school accredited by one of these international bodies grants students eligibility to apply to Japanese universities without needing to take the high school equivalency exam.
Common Post-Graduation Destinations:
- Overseas universities (in the US, UK, Canada, Australia, etc.)
- International liberal arts departments at Japanese universities (e.g., Waseda, Sophia, ICU, Hosei)
- English-taught degree programs at Japanese universities (e.g., PEAK at the University of Tokyo)
Conclusion: Choose an International School Based on Your Goals
International schools offer your child a top-tier English-speaking environment and a global perspective. At the same time, they come with risks, such as high costs and the challenge of maintaining Japanese language proficiency.
Instead of choosing a school simply "so my child can speak English," we recommend clarifying your educational goals—"what kind of learning environment and character traits do we want to cultivate?"—before attending school tours and open houses.
