What Is an International School? Key Differences from Japanese Schools, Admissions Requirements, and Tuition Fees

In recent years, as interest in global education has grown, more families have begun to consider international schools as an option for their children. At the same time, many parents have questions such as, “How is an international school different from a typical Japanese school?” and “Can Japanese children apply?”

This article explains the essential points families should understand when considering an international school, including its defining features, differences from Japanese schools and international preschools, admissions requirements, advantages and potential challenges, tuition fees, and the treatment of graduation credentials.

What is an International School?

An international school is generally a school in which English is the principal language of instruction and education is provided through an internationally oriented curriculum or educational framework. Historically, many international schools were established to enable the children of expatriate families to continue an education comparable to that of their home countries while living abroad. As a result, international schools today offer a range of curricula, including American, British, and other internationally recognised programmes.

In recent years, interest has also grown among Japanese families seeking an internationally oriented education. Beyond learning in English, one of the defining features of an international school is the opportunity to learn alongside people from different cultural backgrounds and to encounter a variety of perspectives as part of everyday school life.

Differences Between International Schools and Japanese Schools

International schools and Japanese schools differ in more than their educational systems. Their curricula, language of instruction, academic calendars, admissions procedures, and approaches to graduation credentials may also vary considerably. Families considering an international school should understand these distinctions and consider which environment best suits their child’s learning needs and future educational pathway.

Differences in Admission Timing and Assessment

Many international schools follow an academic calendar similar to those used in Europe and North America, with the school year beginning around August. At the same time, some schools accept mid-year admissions when places are available, allowing greater flexibility for families relocating to Japan or returning from overseas.

Admissions procedures vary by school. In addition to academic assessments, schools may conduct interviews to evaluate English proficiency and communication skills, request written work or essays, and meet with parents. Where English is the language of instruction, student assessments are generally conducted in English.

Because admissions schedules and selection criteria differ from one school to another, families should review the requirements of their preferred schools well in advance.

Differences in Curriculum and Educational Philosophy

International schools may offer the International Baccalaureate (IB), American or British curricula, or other educational programmes, depending on the school.

Their approaches to teaching and learning also vary, although many place considerable emphasis on inquiry, discussion, presentation, and the development of students’ ability to think independently, formulate questions, and articulate their ideas.

Japanese schools, by contrast, generally follow the Courses of Study established by Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT). This provides a nationally consistent framework through which students progressively develop foundational knowledge and skills across subject areas.

Differences in Language of Instruction

At most international schools, English is used throughout much of the school day, extending beyond classroom instruction to assignments, school events, and communication with teachers and peers. English therefore functions as an everyday language for both learning and social interaction.

Japanese schools, in contrast, primarily provide instruction in Japanese, with English and other foreign languages taught mainly as academic subjects. This distinction between “learning English” and “learning through English” is an important consideration when comparing the two educational environments.

Differences in School Status and Graduation Credentials

Many international schools in Japan are not classified as Article 1 schools under Japan’s School Education Act. Consequently, completing an international school programme does not necessarily confer the same graduation credentials as graduating from a Japanese high school.

However, students who complete programmes at schools accredited by international organisations such as the Council of International Schools (CIS), the Western Association of Schools and Colleges (WASC), the Association of Christian Schools International (ACSI), or the New England Association of Schools and Colleges (NEASC) may, depending on the applicable requirements, be recognised as eligible to apply to Japanese universities. Some schools also offer qualifications such as the IB Diploma, which is widely used for university admissions internationally.

Because the required qualifications vary depending on a student’s intended pathway, families should carefully examine graduation credentials and university eligibility when selecting a school.

Differences in Tuition Fees

Tuition at Japanese public elementary and junior high schools is free as part of compulsory education. Financial support programmes are also available for upper secondary education.

As a general reference, the total cost of education from elementary through high school has been estimated at approximately ¥5 million for students attending public schools throughout and approximately ¥17 million for those attending private schools. *Source: information published by MEXT (December 2019).*

International school tuition, by comparison, can amount to ¥24 million to ¥36 million or more over the course of a child’s education, representing a substantial long-term investment for families.

Tuition is also only one component of the overall cost. Depending on the school, families may need to budget for application or enrolment fees, facility fees, learning materials, school bus services, uniforms, extracurricular activities, and other expenses. It is therefore important to consider the full cost of education through graduation rather than focusing solely on annual tuition.

Differences Between International Schools and International Preschools

International schools and international preschools differ primarily in the ages they serve and the nature of the education they provide.

International preschools generally serve young children from around two to five years of age and provide early childhood education and care in an English-speaking environment. Through play and everyday routines, children become familiar with English while developing age-appropriate social skills, independence, and daily habits.

International schools, by contrast, provide formal education for school-age children, with academic subjects taught through an international curriculum. Some schools, however, offer a continuous educational pathway from early childhood through secondary school, so age ranges and programmes vary considerably between institutions.

Differences Between International Preschools and Licensed Nursery Schools

International preschools and licensed Japanese nursery schools or certified centres for early childhood education and care differ in both their educational approach and their regulatory status.

Licensed nursery schools operate with official approval and must meet government or municipal standards relating to matters such as facilities and staffing. Many international preschools, by contrast, operate as unlicensed childcare facilities and provide programmes developed according to their own educational philosophies.

There are also differences in cost. Public subsidies may reduce fees at licensed nursery schools, whereas families generally bear a larger share of the cost at international preschools. Fees and applicable support schemes vary by institution, so families should confirm the details directly with each school or facility.

At What Age Can a Child Enter an International School?

The age at which children can enter an international school varies by institution. Many schools serve children of compulsory school age, while others include preschool or early childhood programmes and accept children from around two or three years old.

Grade placement and age cut-off dates may also differ from those used in the Japanese school system. Families should therefore check each school’s admissions guidelines based on the child’s date of birth and intended year of entry.

International School Admissions Requirements

Admissions requirements differ by school and grade level. Schools may consider English proficiency, previous academic experience, nationality or overseas residence history, while the availability of places can also affect admissions decisions.

The following are three common areas considered during the admissions process.

English Proficiency Expected of Students

At international schools where instruction is delivered in English, age-appropriate English proficiency may be one of the admissions criteria. Through interviews or assessments, schools may evaluate not only conversational ability but also a child’s capacity to understand instructions and participate meaningfully in learning through English.

For younger children, assessments are often adapted to their developmental stage. Some schools also provide language support, such as English as an Additional Language (EAL), for students with limited prior experience in English. As expectations and support systems differ, families should confirm these details with each school.

Expectations of Parents

Some international schools expect parents to have sufficient English proficiency to communicate effectively with the school, as correspondence, parent-teacher conferences, and information sessions may be conducted in English.

An understanding of the school’s educational philosophy is also important. During parent interviews, families may be asked about their educational values and how they support their child’s learning. Many international schools place considerable importance on a constructive partnership between school and home.

Nationality and Overseas Residence Requirements

Some international schools have admissions policies relating to nationality or previous residence overseas, and certain schools may give priority to children of foreign nationality.

Many schools, however, also welcome applications from Japanese families, and admissions criteria vary widely. Because eligibility requirements and priority categories may change, families should always consult the school’s most recent admissions information.

Advantages of Attending an International School

The value of an international school education extends beyond an English-speaking environment. Students may also benefit from learning alongside people with different cultural perspectives and from educational approaches that encourage independent thought, communication, and active participation in learning.

Developing Practical English Proficiency

At an international school, English is not simply studied as a subject; it is used as a medium for learning across the curriculum. Students use English in lessons, conversations with peers, assignments, and presentations, giving them sustained opportunities to develop the language skills required in authentic academic and social settings.

However, immersion in an English-speaking environment alone does not guarantee strong language development. Appropriate support from both school and home, particularly in relation to a child’s age and English proficiency at entry, remains important.

Growing Through Exposure to Diverse Perspectives

Learning each day with students from different national and cultural backgrounds gives children opportunities to encounter perspectives that may differ from their own and to develop respect for different ways of thinking.

In schools that emphasise inquiry, discussion, and presentation, students are also encouraged to form their own views, communicate them clearly, and listen thoughtfully to the ideas of others. These experiences can help cultivate flexible thinking, effective communication, and a broader international outlook.

Expanding Future Pathways and Connections

Many international schools offer curricula and university guidance designed with overseas higher education in mind, enabling students to consider a broad range of future pathways in Japan and abroad. A diverse school community can also create meaningful connections among students and families from different cultures and backgrounds. These relationships can become an important part of a child’s experience and contribute to a broader understanding of the world.

Potential Disadvantages of Attending an International School

While international schools offer many advantages, there are also practical considerations that families should understand before enrolling. Educational philosophy, future pathways, language development, and the financial commitment involved should all be considered from a long-term perspective.

Higher Educational Costs and the Financial Commitment

International school education generally involves substantially higher costs than public education in Japan. In addition to annual tuition, families may need to pay enrolment fees, facility fees, learning material costs, school bus fees, and extracurricular activity charges.

Because these expenses accumulate over many years, families should consider not only the initial cost of enrolment but also whether the overall educational commitment can be sustained through graduation.

Considerations When Progressing to Japanese Schools

Because many international schools are not Article 1 schools under Japan’s School Education Act, students who later transfer to Japanese schools or apply to Japanese universities may need to meet different eligibility or documentation requirements.

At the upper secondary level in particular, progression options may depend on the school’s accreditation and the qualifications students receive. Families who may consider future study in Japan should investigate these requirements at an early stage.

Possible Challenges in Japanese and English Language Development

An English-medium education can provide valuable opportunities to develop strong English proficiency, but families should also consider how children will maintain and develop age-appropriate Japanese literacy and academic Japanese. Likewise, studying academic subjects in English requires a level of language proficiency beyond everyday conversation. Depending on a child’s English level at entry, it may take time to engage fully with the curriculum. Ongoing attention to language development and appropriate support, when needed, can help children progress successfully in both their learning and communication.

Does Attending an International School Fulfil Compulsory Education Requirements?

For Japanese nationals, attendance at many international schools that are not classified as Article 1 schools may not, by itself, be treated in the same way as attendance at a school recognised under Japan’s compulsory education system.

The specific administrative treatment and any procedures required may vary according to the child’s circumstances, municipality, and the status of the school. Families considering an international school should therefore confirm the relevant requirements with the school and, where necessary, with their local board of education.

International Accreditation Organizations for International Schools

International accreditation can provide one useful point of reference when considering the quality of education and school governance. Well-known organisations and frameworks include the International Baccalaureate (IB), CIS, WASC, ACSI, and NEASC.

Accrediting Organization	Overview & Key Features
International Baccalaureate (IB)	A global education organization offering internationally recognized programmes, including the IB Diploma Programme (DP), which is widely accepted for university admission.
Council of International Schools (CIS)	A global membership organization that evaluates and accredits international schools based on internationally recognized standards for educational quality.
Western Association of Schools and Colleges (WASC)	A U.S.-based accrediting organization that evaluates schools against established standards for educational quality and continuous improvement.
ACSI / NEASC	ACSI accredits Christian schools worldwide, while NEASC accredits international and U.S. schools based on established standards for educational quality.

These organisations evaluate schools according to their respective standards, which may include areas such as educational provision, student learning, governance, and organisational practices. Accreditation can therefore offer valuable information about a school, although the purpose and scope of each accreditation differ.

Families should consider accreditation alongside other factors, including curriculum, educational philosophy, learning environment, and university guidance, rather than treating accreditation alone as a measure of whether a school is right for their child.

Points to Consider Before Choosing an International School

When considering an international school, families should look beyond the appeal of the educational environment itself and consider future pathways, overall costs, the relationship with the Japanese education system, and the support a child may need at home.

Choose a School with Future Pathways in Mind

School selection should take account of the range of possibilities a child may wish to pursue in the future. The most appropriate curriculum and graduation credentials may differ depending on whether a student intends to apply to universities overseas, in Japan, or wishes to keep both options open.

There is no need to determine a young child’s future path too early. Nevertheless, understanding the progression routes a school can support allows families to preserve flexibility as their child’s interests and aspirations develop.

Consider the Full Cost of Education, Not Tuition Alone

International school fees often extend well beyond tuition. Enrolment fees, facility charges, learning materials, school transportation, field trips, and extracurricular activities can all contribute to the annual cost.

Fees may also increase as students progress through the school. Families should therefore consider the financial commitment over the medium to long term, rather than assessing affordability on the basis of a single academic year.

Understand the Differences from the Japanese Education System

Many international schools occupy a different legal and educational position from Article 1 schools in Japan. As a result, matters related to compulsory education, high school graduation credentials, and eligibility for admission to Japanese universities may be handled differently.

Families who may later consider transferring to a Japanese school or applying to a university in Japan should review the school’s accreditation, graduation credentials, and university progression record in advance.

Establish Support at Home

As children adapt to a new language environment and school culture, understanding and support at home can make an important difference. Parents need to remain informed about school communications, maintain constructive dialogue with teachers when necessary, and pay attention to changes in their child’s academic and personal wellbeing.

Particularly during the early stages of enrolment or periods of greater linguistic challenge, close observation and cooperation between home and school can help identify the support a child may need.

Conclusion

International schools offer children the opportunity to learn in an internationally oriented, predominantly English-speaking environment while engaging with a wide range of cultures and perspectives. Curricula, educational philosophies, admissions requirements, accreditation, and graduation credentials differ from school to school, and international schools also occupy a different position from mainstream Japanese schools in several important respects.

For this reason, choosing an international school should involve more than considering the opportunity to learn in English. A child’s learning style and personality, future educational options, the family’s educational priorities, and the long-term financial commitment should all form part of the decision.

Yoyogi International School is an authorised International Baccalaureate (IB) Primary Years Programme (PYP) school and a CIS-accredited school. It provides an inquiry-based learning environment within an internationally diverse community while valuing each student’s individuality.

Families considering an international school are encouraged to look beyond information available online and visit schools whenever possible. Information sessions and school visits provide an opportunity to experience the learning environment, understand the school’s educational philosophy, and consider whether it is the right fit for their child. Yoyogi International School also welcomes enquiries from families exploring international education.
