International Schools in Japan: A Practical Guide for Relocating Families

Japan's international school landscape is concentrated in Tokyo and a handful of other major cities, with a mix of long-established accredited schools, newer entrants and Japanese private schools with English-medium programmes. Here's how the landscape actually breaks down.

International schools in Japan

Quick answer

A parent's guide to international schools in Japan: where they're concentrated, how they differ, capacity pressure in Tokyo, and how to start your search.

At a glance

What counts as an international school in Japan

In Japan, the term "international school" covers a genuinely wide range of institutions, and it's worth understanding the differences before you start comparing options. At one end are long-established, internationally accredited schools that have operated in Japan for decades, typically teaching entirely in English, following a recognisable overseas curriculum (American, British, IB or another national system), and serving a mostly expatriate and returnee student body. At the other end are Japanese private schools that have added English-medium programmes or international departments, sometimes alongside their regular Japanese-curriculum classes, aimed partly at Japanese families wanting bilingual education for their children as much as at expatriate families.

Between these two poles sit various hybrid models, including bilingual schools with dual-language instruction and smaller, newer schools built around a specific curriculum niche. None of these models is inherently better than another, but they suit different family situations, so it's worth being clear about what you are actually looking at before assuming a school labelled "international" matches what that word might mean in another country.

Where international schools in Japan are concentrated

Tokyo has by far the largest concentration of international schools in Japan, reflecting the size of its expatriate community and the presence of many multinational employers and embassies in the city. Within Tokyo, schools are spread across a number of different areas, and commute times can vary considerably depending on where a family lives relative to a specific campus, so it's worth checking a school's exact location against your planned neighbourhood before shortlisting it.

Outside Tokyo, the picture changes quickly. Yokohama, Nagoya, and the Kansai region (including Osaka and Kobe) each have a smaller number of established international schools, generally reflecting local expatriate communities tied to specific industries, such as manufacturing or trade. Other Japanese cities may have very limited or no dedicated international school provision at all, and families relocating outside the main metropolitan areas should expect a materially thinner set of options, sometimes requiring a boarding arrangement or a longer commute to the nearest suitable school. If your relocation is to a city outside Tokyo, treat schooling as a research priority well before committing to a specific neighbourhood or even a specific city, since availability is far less certain than in Tokyo.

Accredited international schools versus Japanese schools with English programmes

Internationally accredited schools in Japan are generally recognised by bodies such as the Council of International Schools (CIS), the Western Association of Schools and Colleges (WASC), or curriculum-specific bodies like the International Baccalaureate Organisation, depending on what they teach. Accreditation is a useful signal of an external quality review, though it isn't the only thing that matters, and it's still worth visiting a school and speaking to current parents rather than relying on an accreditation badge alone.

Japanese private schools offering English-medium or bilingual programmes are a genuinely different category. Some are well regarded and popular with both Japanese and international families, particularly those wanting a bilingual outcome for their children, but the balance of English versus Japanese instruction, the curriculum followed, and the pathway to university can vary significantly between schools. If your child does not yet speak Japanese and you are considering one of these schools, ask specifically how much of the school day and assessment is conducted in Japanese versus English, since this varies far more than the phrase "bilingual programme" might suggest.

Understanding ichijoko (Article 1) status

One piece of Japan-specific terminology worth understanding is "ichijoko", or Article 1 school status, referring to schools formally recognised under Japan's School Education Act as meeting Japan's national curriculum standards. Most fully international, foreign-curriculum schools in Japan do not hold ichijoko status, since they generally do not follow the Japanese national curriculum, and instead operate under a different legal designation, sometimes as "miscellaneous schools" (kakushu gakko) or another category.

This distinction matters in a few practical ways: it can affect a school's eligibility for certain forms of government subsidy, and it can also affect how a period of study at that school is treated if a child later transfers into the mainstream Japanese school system. If your family anticipates a possible move between an international school and the Japanese national system at some point during your time in Japan, ask both the sending and receiving institutions directly how a transfer would be handled, since practice varies and general assumptions can be misleading.

Curriculum options available in Japan

International schools in Japan offer a range of curricula, including American-style programmes leading to a US high school diploma often combined with Advanced Placement subjects, British curriculum schools offering IGCSEs and A-levels, and IB World Schools offering some or all of the Primary Years, Middle Years and Diploma Programmes. A smaller number of schools follow other national curricula, such as French, German or other systems, generally serving specific national expatriate communities.

Our separate guides to IB schools, British schools and American schools in Japan go into more detail on each of these pathways specifically, including what to ask when comparing them.

Capacity pressure and why early applications matter

Tokyo's international schools have faced periods of significant capacity pressure, driven by a combination of an increase in the international workforce in the city and a relatively limited number of schools able to expand physical campus space in a dense urban environment. Waiting lists at some popular schools and grade levels are a real possibility, and this can vary year to year and school to school, so don't assume that a strong reputation automatically means a school has no space, nor that a lesser-known school will necessarily have easy availability.

Because of this, families relocating to Tokyo are generally well advised to begin the school search process as early as realistically possible, ideally as soon as a move to Japan becomes a firm plan, rather than waiting until arrival. Employers relocating staff to Japan sometimes build school-search support into their relocation packages specifically because of this dynamic, so it's worth asking your employer what support is available.

Not sure which schools fit your family?

Choosing an international school depends on your child's age, curriculum preference, location and budget. Tell us what you're looking for and we'll help you identify schools worth considering.

Get matched with international schools

Assessment, English proficiency and prior records

Most accredited international schools in Japan will ask for a child's prior school reports and, particularly for children joining without prior English-medium schooling, some form of English-language assessment as part of the admissions process. This is a genuinely common requirement across the sector, reflecting the fact that instruction is conducted almost entirely in English at most of these schools, and a child without adequate English proficiency may need additional support that a school may or may not be resourced to provide.

Requirements and the format of assessment vary by school and by age group, so ask a shortlisted school directly what documentation and assessment it requires, and how far in advance of a start date these need to be completed, since some schools require this well before a final admissions decision can be confirmed.

The Japanese school year and international school calendars

One of the more disorienting aspects of moving to Japan with school-age children is the mismatch between the Japanese national school year, which runs from April to March, and the calendar followed by most international schools in Japan, which generally follows the northern-hemisphere pattern of starting in August or September and running through to June. This means the two systems are essentially out of step with each other for most of the year.

This mismatch has practical consequences worth thinking through in advance. A family moving to Japan mid-year may find that an international school has a clear entry point at the start of its own academic year but only limited space at other points in the year. Families with a child who may move between the Japanese national system and an international school at some stage should also think carefully about timing, since a transfer that looks straightforward on paper can be complicated by the two calendars not aligning. Our guide to term dates and the academic year in Japan covers this in more detail.

Compulsory education rules and foreign residents

Japan's compulsory education laws formally apply to Japanese nationals, requiring attendance in elementary and lower-secondary education. In practice, foreign resident families are generally permitted, and in many cases encouraged, to enrol their children in local Japanese public schools free of charge if they choose to do so, as an alternative to a fee-paying international school. This is a genuinely different situation from some other countries and worth being aware of, even if most expatriate families ultimately choose an international school for continuity with their home country's system or because of a lack of Japanese language ability.

If you are weighing a Japanese public school against an international school for your child, it's worth discussing your specific situation with your local ward or city education office, and separately with any international school you are considering, since requirements, expectations, and the level of support for non-Japanese-speaking children can vary considerably.

Regional coverage beyond the biggest cities

Beyond Tokyo, Yokohama, Nagoya and the Kansai cities of Osaka and Kobe, dedicated international school options thin out considerably. A small number of other cities may have a single international or bilingual option, but many parts of Japan have essentially no international school provision within a reasonable commuting distance. If your relocation involves a smaller city or a more rural posting, it is worth researching schooling options as one of the very first steps in your planning, since the answer may meaningfully affect where within a region you choose to live, or whether boarding elsewhere in Japan becomes a consideration.

Fees, and why they're covered in a separate guide

Fees at international schools in Japan vary considerably by school, campus, and grade level, and are generally quoted in Japanese yen with additional charges commonly layered on top of tuition, such as entrance or facility fees and bus transport. Because this is a substantial topic in its own right, and because getting it wrong can meaningfully affect a family's relocation budget, we cover it in a dedicated guide rather than trying to summarise it briefly here.

How international schools in Japan differ from the Japanese national system

Families new to Japan sometimes want to understand how international schools compare with the Japanese national education system more broadly, including matters like class sizes, teaching style, and the university pathways each leads to. That comparison is a substantial topic in itself and is covered by ExpatSchoolGuide's separate guide to the Japanese education system, which focuses specifically on how the national system works rather than on international schools.

Rankings and reputation: treat them as one input, not the answer

It's natural to want a ranked list of the "best" international schools in Japan, and ExpatSchoolGuide has a separate guide that looks specifically at that question for readers who want it. But reputation and rankings, however they are compiled, are only one input into a decision that should also weigh your child's specific needs, the school's location relative to where you'll live, its curriculum, its capacity to admit your child at the grade level and time of year you need, and how it felt when you actually visited. A highly ranked school that cannot admit your child until a year from now, or that sits ninety minutes from your home, is not necessarily the right choice for your family.

Visiting schools and what to ask while you're there

Questions worth asking on a school visit in Japan

Where possible, visiting a shortlisted school in person, or via a virtual tour if a visit before relocation isn't practical, remains one of the most useful steps in the process. Beyond the general questions any parent would ask, in Japan it's worth specifically asking about the school's academic calendar and how it handles mid-year admissions, its approach to supporting children with limited or no prior English exposure, whether it holds ichijoko status or another designation and what that means practically for your family, and what its current waiting list situation looks like for the grade level your child will be entering.

Starting your search

Given the concentration of options in Tokyo, the capacity pressures at some schools, and the calendar mismatch with the Japanese national system, families relocating to Japan are generally better served by starting the school search early, being realistic about which schools can genuinely accommodate their child's grade level and preferred start date, and treating a visit or thorough direct conversation with each shortlisted school as essential rather than optional. Our guide to how to apply covers the practical steps of the admissions process itself in more detail.

Frequently Asked Questions

How many international schools are there in Japan?

The number changes over time as schools open, close or merge, so we don't quote a fixed figure. Tokyo has by far the largest concentration, with smaller numbers in Yokohama, Nagoya and the Kansai region.

Is Tokyo the only place with real international school options?

It has the largest and most varied concentration, but Yokohama, Nagoya, and Kansai cities like Osaka and Kobe also have established options. Coverage thins considerably outside these areas.

What does ichijoko (Article 1) status mean?

It refers to formal recognition under Japan's School Education Act for schools following the Japanese national curriculum. Most foreign-curriculum international schools do not hold this status and operate under a different designation instead.

Can foreign families send their children to Japanese public schools instead of an international school?

Generally, yes — foreign resident families can usually enrol children in local public schools free of charge, though language support and practicalities vary by area. Discuss your situation with your local ward or city education office.

Do international schools in Japan follow the same school year as Japanese public schools?

No. Most international schools in Japan follow an August or September to June calendar, while the Japanese national system runs April to March. This mismatch is worth planning around.

Is it hard to get a place at a popular international school in Tokyo?

Some popular schools and grade levels do experience capacity pressure and waiting lists, though this varies by school and by year. Applying as early as possible improves your options.

Do international schools in Japan require an English test for admission?

Many do, particularly for children without prior English-medium schooling, though exact requirements vary by school and age group. Ask a shortlisted school directly.

What's the difference between an international school and a Japanese school with an English programme?

International schools generally teach entirely in English on a foreign curriculum, while Japanese schools with English programmes usually blend Japanese and English instruction to varying degrees. Ask specifically how much of the day is taught in each language.

Should I choose a school based on rankings alone?

Rankings can be a useful starting point but shouldn't be the only factor. Location, curriculum fit, capacity to admit your child at the right time, and how the school feels on a visit all matter as much or more.
