The Tokyo tech footprint, in plain terms
The Tokyo technology footprint is broader than the visible flagship offices suggest. The major US platform companies all run engineering, product, sales and customer functions in the city, and the Japanese cloud and AI build-out has drawn in significant overseas headcount across software engineering, infrastructure, machine learning and applied research. European technology employers run sizeable Tokyo presences in industrial automation, semiconductor design, semiconductor equipment and software-as-a-service. Indian and Singapore based regional headquarters route mid-career engineering and product talent through Tokyo for two and three year postings.
The practical implication for the schools decision is that most tech families arriving in Tokyo expect to move again within four to six years, whether back home, on to Singapore or Seoul, or into a US headquarters role. The schooling choice has to handle a likely future move cleanly. That favours the major international school curricula that transfer well across borders and is the principal reason the IB Diploma and the American AP system carry such heavy weight in the Tokyo decision matrix.
The shortlist tech families actually use
Five schools handle the bulk of tech industry enrolment in Tokyo. Each suits a different combination of curriculum preference, working language at home, commute logic and likely next destination.
The American School in Japan (ASIJ). The default choice for US technology families on Tokyo postings, particularly those routed through Bay Area or Seattle headquarters. American curriculum with AP track. Strong STEM provision and a substantial university counselling team focused on US destinations. Chofu campus sits west of central Tokyo with a developed bus network into the central wards. The single largest school in the Tokyo international school market by enrolment.
Tokyo International School. Full IB continuum from PYP to DP. Strong fit for tech families likely to move again before sixth form, particularly to Singapore, Hong Kong, London or another European posting. The Minato ward location places it within easy commute of the central tech employer cluster around Shibuya, Roppongi and Otemachi. Faculty stability and small year groups make it a strong fit for families relocating mid-year.
The British School in Tokyo (BST). British curriculum from primary through to A Level. The Shibuya campus sits inside one of the densest English-speaking expat corridors in Tokyo. Suits UK and Commonwealth families and those with children likely to head to the UK Russell Group for university. Strong STEM A Level cohorts and a growing computer science option in sixth form.
K International School Tokyo. Full IB continuum, located in Koto ward. Smaller than ASIJ but with an unusually diverse student body and strong IB Diploma outcomes. Particularly popular with European and Indian tech families and with US families based on the eastern and central side of the city. Easy commute from Chuo and Koto wards.
Aoba Japan International School. IB authorised across PYP, MYP and DP, with a bilingual track that suits mixed nationality families with a Japanese parent. The Hikarigaoka campus serves the western wards and the Bunkyo campus the central north. Fees sit slightly below the ASIJ and BST benchmark, which makes Aoba a sensible option for families on more modest relocation packages.
Compare two or three Tokyo schools side by side
Most tech families end up choosing between two or three schools on the shortlist. Use the school compare tool to put ASIJ, BST and Tokyo International side by side on fees, curriculum, university destinations and admissions windows. Pair the compare view with our best international schools in Tokyo overview and the best IB schools in Tokyo piece, then open the Tokyo city guide for the housing and commute picture.
Neighbourhoods that match the schools
Tokyo is large by Asian capital standards and the morning commute window matters. Most tech expat families anchor to one of three corridors.
Minato ward. The densest cluster for English-speaking tech families. Hiroo, Azabu, Roppongi and Akasaka offer dense international school bus coverage, established expat infrastructure and immediate access to the major central employer footprints. Tokyo International School sits in Minato. ASIJ and BST run buses through Minato. Family-sized apartments command meaningful rent premiums, typically JPY 600,000 to JPY 1,200,000 per month for three bedroom apartments in the central blocks.
Shibuya, Meguro and Setagaya. The western corridor running from central Shibuya through Daikanyama, Nakameguro, Jiyugaoka and Setagaya is the established alternative to Minato and is particularly popular with families at BST and the western Aoba campus. Larger family stock and slightly lower rent levels than central Minato. Setagaya in particular suits families with children at ASIJ in Chofu because the western commute logic is much cleaner.
Chofu and Denenchofu. Suburban western Tokyo, the immediate ASIJ catchment. Lower density, more green space, larger family homes than central Tokyo, but a longer commute into the central business districts. Suits tech families whose working parent has flexible office attendance or works from a Setagaya or western office. The right answer for ASIJ families who prioritise commute proximity.
Curriculum choice for likely next moves
The cleanest way to choose curriculum is to work back from the likely next two or three moves. Families anchored to the US for university favour the American curriculum and AP, which makes ASIJ the natural default. Families with a likely UK, Singapore or Hong Kong next move favour the IB Diploma, which transfers cleanly between international schools globally and is the dominant curriculum at the most mobile families' shortlist. Families on a UK passport with a likely return to the UK by sixth form favour A Levels at BST.
The structural advantage of the IB Diploma in international tech mobility is significant. A child taking the IB at Tokyo International, K International or Aoba can transfer into an IB Diploma in Singapore, London, Amsterdam or Munich without losing curriculum continuity. A child on the AP track can move within the US international school network but transitions into IB or A Levels with more friction. Our IB versus American curriculum and IB versus British curriculum pieces walk through the curriculum trade-offs in more depth.
Fees and what tech relocation packages cover
Tokyo international school tuition in 2026 sits broadly between JPY 2.4 million and JPY 3.6 million per child per year depending on the school and year group, with capital levies, lunches, bus fees and extra-curricular charges adding 10 to 20 per cent to the bill. The all-in year one outlay sits realistically at JPY 2.8 million to JPY 4.2 million per child. Tech industry relocation packages vary widely on schooling cover. Senior engineering, machine learning and infrastructure roles routinely come with full school fee coverage for two children. Mid-career product, design and operations packages often cover only a partial contribution, and self-funded relocations are increasingly common for tech families on remote work contracts.
Families should pin down the school fee policy clearly before signing the offer letter. The most common shortfall sits between the published tuition figure used in the offer letter and the actual all-in fee invoice in September, which catches several families a year unprepared. Run the year one number through our cost calculator and read the Tokyo international school fees piece for the structural fee picture.
Admissions timing and the typical tech family pattern
September is the principal start date at every Tokyo international school. Most tech relocations book the start either at September or at the January or April mid-year intake points. For September entry, applications typically open the previous October and close between January and April depending on the school. Popular year groups at ASIJ, BST, Tokyo International and K International run waiting lists for the most competitive year groups, particularly the year 1 and year 7 transition points.
The typical tech family pattern looks like this. Offer letter signed in March or April. Family confirms Tokyo placement and starts the school shortlist immediately. Two school tours during a one week orientation visit in May or June. First choice school admissions test and interview in June or July. Confirmation by mid-July, with a deposit paid soon after. School start in late August or early September. Mid-year intakes follow the same compressed timeline. Families relocating with less than two months runway typically end up with the second or third choice on the shortlist because the most popular schools have filled by then.
A realistic first year plan
The cleanest version of a Tokyo tech family relocation looks like this. Confirm the school choice before booking the long-term lease, since the school decision changes the housing decision materially. Plan two visits before the move, one for schools and one for housing, if the timing allows. Front-load the family logistics in the first ninety days, including the family residence card paperwork, the children's school enrolment paperwork and the household goods clearance through customs. Our moving to Tokyo with children guide walks through the practical logistics of the first ninety days, and the Tokyo city guide covers the broader expat picture.
Tech families often move once in the first two years inside Tokyo, typically from a Minato apartment to a Setagaya or Chofu house if the children are at ASIJ. Build the flexibility into the first lease, or take a serviced apartment for the first three months while the family decides. The same flexibility helps if the school decision proves wrong for the child, although the most common pattern is a settled school by month four and a stable family routine by month six.
FAQ
Which Tokyo school is most popular with tech expat families?
The American School in Japan in Chofu carries the largest concentration of US tech families on Japan postings. Tokyo International School in Minato is the natural alternative for IB families. The British School in Tokyo and K International School also carry sizeable contingents of technology industry families.
Where do tech expat families typically live in Tokyo?
Minato ward, especially the Hiroo, Azabu and Roppongi corridor, is the densest cluster for English-speaking tech families. Shibuya, Meguro and Setagaya are common alternatives. Families with children at ASIJ in Chofu often settle further west toward Denenchofu, Setagaya and Chofu itself.
Is the IB or American curriculum better for tech industry children?
Neither is structurally better for tech industry careers. The IB favours families likely to move again before sixth form, since it transfers cleanly worldwide. The American AP route makes more sense for families anchored to US university destinations. Both produce strong STEM outcomes when the school is strong.
How much do Tokyo international schools cost?
Tuition sits between JPY 2.4 million and JPY 3.6 million per child per year in 2026, with capital levies, bus, lunches and trips adding 10 to 20 per cent. The all-in year one figure sits realistically at JPY 2.8 million to JPY 4.2 million per child.
Do tech industry relocation packages cover Tokyo school fees?
Senior engineering and machine learning packages routinely include full coverage for two children. Mid-career product and design roles often include partial coverage or none. Families on remote contracts increasingly self-fund. Confirm the policy in writing before accepting the offer.
