Online School in Japan: Returnee Children, Rotating Executives, and the Hours After School

By Alfred Ouko, Founder · October 2026 · 9 min read

Japan’s international families are concentrated and easy to describe. They are in Tokyo, especially Minato and Setagaya; in Yokohama; in Kansai between Osaka and Kobe; around Nagoya and the Toyota supply chain; and in Okinawa, around the US bases. Alongside them is a group that is particular to Japan: kikokushijo, Japanese children returning from years abroad, often fluent in English and educated in Cambridge, IB or American schools. The international schools that serve these families, the American School in Japan, the British School in Tokyo, Yokohama International School, Canadian Academy in Kobe and others, are excellent and full-time. This guide is about the families for whom a full-time international school is not the answer, and what a live online school can do after the Japanese school day ends.

Kikokushijo: keeping English-medium study alive

A child who has spent four years in a London or Singapore school and returns to a Japanese school faces two problems at once: catching up in Japanese, and losing the academic English they built abroad. Many families choose the Japanese school for good reasons, including belonging, language and the Japanese university route, and still want to keep a Cambridge or IB track going. Two or three live subjects after school, taught in English to an examined standard, keep that track alive. Japanese universities’ returnee admissions often look for exactly this kind of record, though requirements differ by university. The track also gives the child a reason to read and write academic English every week, which is the habit that fades fastest after a return.

Families on rotation

Japan’s trading houses, such as Mitsubishi Corporation and Mitsui & Co., and its automotive makers, Toyota in Aichi and Nissan in Yokohama among them, send executives abroad on multi-year postings. A child may move from Tokyo to London to Bangkok and back. Each move between school systems costs something. A curriculum that stays the same, with the same teachers and the same examination board wherever the family lives, removes much of that cost. The same applies to foreign families posted to Japan who expect to move on in a few years. For them the logic runs the other way: the child keeps the curriculum they will need at the next school, wherever that turns out to be.

The legal position and the after-school slot

Japan’s compulsory education, six years of elementary and three of middle school, applies to Japanese nationals, and is met through schools recognised under the School Education Law. Many international schools are not in that category. For Japanese-national children our advice is clear: keep the Japanese school enrolment and use Smartious as supplementary study. Foreign-national families should confirm their own position with their local board of education; families connected with the US bases follow their own arrangements, and students at DoDEA schools can add AP alongside. Japan is six hours ahead of Nairobi with no daylight saving, so our afternoon teaching lands in the Japanese evening, the same hours many families already give to juku. Every lesson is recorded.

What families actually study

Most choose two or three subjects: English Language or Literature to keep academic English strong, Mathematics, and one or two of Physics, Chemistry, Biology, Economics or Computer Science. These lead to Cambridge IGCSE and A-Level, or Pearson Edexcel equivalents, and AP for families with US plans. Cambridge and Pearson Edexcel examinations are sat at authorised exam centres, which families book; most are in Tokyo, and centres are confirmed per family, per session. Students who start at twelve or thirteen typically sit IGCSE at fifteen or sixteen, and can then continue to A-Level while finishing Japanese high school. AP suits students bound for US universities who want college-level courses on their record. For families outside Tokyo, exam travel is a few trips a year by Shinkansen or plane.

Honest limits

A Japanese school day, followed by club activities and then an online class, is a long day, and we would rather a child take two subjects well than four badly. We do not replace the campus, sport and community of an international school, and for families who want and can access that, it is the better choice. And a child fully settled in Japanese school and aiming at a Japanese university through the Common Test does not need us; the Japanese system serves that goal well. We also say plainly that a returnee child’s Japanese matters; keeping the Japanese school strong is part of the plan, not an obstacle to it. We will tell you if we think the load is too heavy.

For returnee children, rotating families and those who want to keep an English-medium track going alongside Japanese school, a few live subjects in the evening can carry a great deal. Keep the Japanese school, choose subjects carefully, and let the examined record build quietly. If that fits your family, book an assessment and we will suggest a realistic starting point.

Frequently asked questions

Can a Japanese-national child study with Smartious instead of a Japanese school?

We recommend against it during the compulsory years. Keep the Japanese school enrolment and use our classes as supplementary study; check any other arrangement with your local board of education.

What times are live classes in Japan?

Japan is six hours ahead of Nairobi with no daylight saving, so our afternoon classes fall in the Japanese evening after school. Every lesson is recorded.

Will this help with returnee university admissions?

An examined Cambridge, IB or AP record is the kind of evidence returnee admissions often consider, but requirements differ by university, so check each one.

Where would exams be sat?

At authorised exam centres, which families book, mostly in Tokyo. We confirm a centre per family, per session.

“What I love most about Smartious is how they make learning enjoyable. The tutors use engaging methods that keep children interested throughout the lesson. My child now looks forward to studying instead of avoiding it.” — Google reviewer, Google review
