If you are searching for international schools in Minato, Tokyo, you have landed in the densest school neighborhood in the country. Moto-Azabu, Hiroo, Shirokanedai, Minami-Aoyama — within a short walk of one another you will find several world-class schools. That abundance is a gift, but it can also make the decision harder: which one actually fits your child and your family? In this guide we compare seven real international schools located in Minato honestly, by curriculum, fee range, and character. We also share an eighth option — an online path — for families for whom fees or the daily commute have become a real barrier. By the end, the criteria that matter for your child should feel much clearer.
International schools in Minato: the landscape and typical fees
Counting international preschools, Minato-ku is home to more than thirty schools. With embassies and multinational companies concentrated here, the ward has long drawn expatriate families, international couples, and globally minded Japanese households — and schools have grown to meet that demand. Geographically, the established K-9 and K-12 schools cluster around Azabu, Moto-Azabu, and Minami-Azabu; science-focused and newer schools sit in Shirokanedai and Minami-Aoyama; and early-years preschools dot Akasaka, Toranomon, and Shibakoen.
On fees: for full international schools spanning early years through secondary, annual tuition in Minato typically runs from roughly 1.7 to 3.4 million yen. The best-known K-9 and K-12 schools cluster in the 2.8 to 3.4 million yen range, and once you add registration, building, and bus fees, the first year can exceed 4 million yen. Science- and Cambridge-oriented schools offer more moderate options, with primary tuition around 2 million yen a year.
Note: all fees reflect publicly available information as of July 2026. Always confirm the latest figures on each school’s official website.

How to find the right fit for your family
Even with seven schools laid out, “so how do I actually choose?” is the honest question. It helps to think of Minato’s options in three types: (1) established major international schools, (2) mid-size and newer international schools, and (3) online international schools that require no commute. The table below shows, honestly, how each type tends to perform on cost, ease of admission, commute, and more.
Major schools offer superb facilities and strong pathways, but with higher fees and tougher admission. Mid-size, newer, and science-focused schools can be easier to choose on cost and flexibility, though some are still building their scale and track record. And the option not to overlook: schooling that does not depend on a daily commute. It is worth asking honestly whether fees are straining the household, and whether a long cross-city commute is wearing your child down.

When fees or the commute are the barrier — an online eighth option
Minato is a privileged place for school choice. Even so, annual tuition above 3 million yen, or a daily drop-off and pick-up through crowded central Tokyo, becomes a real barrier for many families. If you find yourself thinking, “I want an international education for my child, but I’m not sure we can sustain this for years,” there is an eighth option that does not depend on commuting: an online international school.
We are NIJIN GLOBAL ACADEMY (NGA), an online international school scheduled to open in September 2027. It is run by NIJIN Inc., the company behind NIJIN Academy, an alternative school in Japan with more than 1,000 enrolled students. Rooted in a “beyond test scores” philosophy — not ranking children by exam points — NGA centers on small-group dialogue and a mission to help children “come to love themselves and the world.” It serves ages 6 to 18 across Asia and Oceania, regardless of where you live, and is designed so children can lean on Japanese while gradually growing into English. We aim for tuition at roughly one-fifth of a bricks-and-mortar international school.
In honesty: NGA has not opened yet, and its track record is still to come. It cannot offer the same playground and on-campus experience as a commuting school. Even so, for a family weighing options in Minato, learning that connects to the world without the commute and at a lower cost may be a path worth considering.
Frequently asked questions
Q. From what age can children enter international schools in Minato?
A. Many preschools accept children from around 12–18 months, and Minato is especially rich in early-years options. Schools like Nishimachi and The Montessori School of Tokyo run continuously from early childhood into the secondary years. A good first step is to shortlist schools that accept your child’s current age.
Q. Is Japanese-language support available?
A. It varies greatly by school. Some, like Nishimachi, are explicitly bilingual in English and Japanese; others teach primarily in English. If you want a solid Japanese foundation maintained, look at bilingual schools, or an online school (such as NGA) designed with Japanese-language support in mind.
Q. Can my child transfer in mid-year?
A. Most schools accept transfers, but popular ones rarely have openings, and conditions vary by term and grade. Entrance tests, interviews, or English-level requirements may apply, so it is wise to contact schools directly about a year before your intended start date.
The time you spend deciding is time spent loving your child
There is no single “right answer” to choosing a school. Even in a place as rich in options as Minato, what matters is less “can we get in?” and more “can we sustain this learning, comfortably, for years?” Fees, commute, your child’s temperament — every family’s situation is different. That is exactly why the time you spend hesitating is proof of how seriously you are thinking about your child’s future. Take your time, visit a few schools in person, and compare. And if you would like to keep a “beyond the commute” path on your list too, we would be glad for you to consider our opening.
