Foreign Families in Aichi: Schools, Benefits & Where to Settle

Whether your family has been in Aichi for two generations or you have just arrived to join a spouse on the factory floor, you have landed in the prefecture that, more than any other, was built around foreign families who came to stay. The everyday questions are the same everywhere: which school to choose, how to get your children's medical bills covered, whether your long-term-resident status can become permanent, and where to find someone who speaks Portuguese when the paperwork gets hard.

This guide walks through all of it — where families live and what rent costs, daycare and the Japanese-versus-Brazilian school choice, child benefits and medical subsidies, health insurance, the visa road from 定住者 to permanent residence, driving, and multilingual support — using Aichi's own published numbers and its own consultation desks. It is written for families who plan to put down roots.

Aichi at a glance: Japan's biggest Nikkei Brazilian community

Aichi had 345,900 foreign residents as of 30 June 2025, the third-highest of any prefecture. The largest single nationality is now Vietnamese at 67,842, with Brazilians second at 61,003 (30 June 2025) — but it is the Brazilian community that gives the prefecture its family character. These are largely second- and third-generation Nikkei (people of Japanese descent) whose roots trace back to the families who arrived in the 1990s to staff the region's car plants. Nationwide, Brazil is a comparatively small community — about 210,014 Brazilians in all of Japan at the end of 2025 — which makes Aichi's concentration remarkable: roughly three in ten Brazilian residents in the entire country live in this one prefecture.

The crucial thing to understand is that this community is not in downtown Nagoya, which has only about 4,437 Brazilian residents. The Brazilian families cluster in the Mikawa manufacturing belt east and south of the city: Toyohashi has 9,133 Brazilians (the city's single largest nationality), Toyota 7,312, Okazaki 4,811, Nishio 4,134, Toyokawa 3,250 and Chiryu 2,620 — where Brazilians are about 43% of all foreign residents (all 30 June 2025). The pattern is tied to the car industry: Toyota Motor is headquartered in Toyota City, and the supplier cluster around Kariya and Anjo drew Nikkei workers after the 1990 revision of the Immigration Control Act opened employment to people of Japanese descent. Employers housed them in company dorms and estates such as Toyota's Homi Danchi, where the foreign share is now 31.3% across the wider Homi district (1 May 2025) and reportedly around 58% inside the housing estate itself (2024).

Where foreign families live, and what the rent looks like

There is a clear financial logic to why families settle in Mikawa rather than downtown Nagoya. As of 10 July 2026, SUUMO's monthly average for a family-sized 2LDK/3DK was roughly ¥68,000 in Toyota and ¥59,000 in Toyohashi, against about ¥132,000 for the same size in central Nagoya's Naka Ward. Even inside Nagoya, the foreigner-heavy wards of Minato and Nakagawa sit near ¥62,000–70,000. That gap is why the settled Nikkei population concentrates in the manufacturing towns and in Nagoya's cheaper wards.

Those cities are not treating foreign residents as temporary, either. Toyota's own figures show 7,081 residents holding permanent residence (永住者) and 4,292 holding long-term-resident (定住者) status (1 May 2025) — roughly 11,000 people in the settled-family layer, sitting alongside a factory workforce on trainee and specified-skilled-worker visas. Renting as a foreign family still brings the usual hurdles: a guarantor company, key money and Japanese-only screening. If you are searching now, read our guide to rental contracts, guarantors and fees, the five reasons foreigners get rejected, and the first-year settling-in checklist. Because so many Mikawa landlords already rent to foreign families, screening tends to be easier here than in central Tokyo — but a local gut check helps, and on LO-PAL you can ask a Japanese resident whether a specific building or agency is used to foreign tenants before you sign anything.

Daycare and hoikuen for working parents

In most manufacturing households both parents work, so licensed daycare (hoikuen) is usually the first system you deal with. Places are allocated by a municipal points system that favors households where both parents work full-time — not first-come, first-served — and the application runs through your city hall in Japanese. Start with our daycare guide for foreign parents and the step-by-step hoikuen application walkthrough, which explain the point system and the enrollment calendar.

From 2026 a new national scheme also lets families use a set number of daycare hours without the usual work requirement, so a stay-at-home parent can still get a child into care part-time; we cover it in our kodomo-daremo-tsuen (child-anyone-can-attend) guide. Ask your city's childcare desk whether Portuguese or other language help is available — in the Mikawa cities, it often is.

School: Japanese public school or a Brazilian school?

This is the decision that defines many Nikkei families in Aichi, and the prefecture is unusual in genuinely offering both.

Japanese public school is effectively free, close to home, and the fastest route to full bilingualism and integration. Public elementary and junior-high schools accept foreign children at no tuition cost, and Aichi runs a "Pre-school" program that gives foreign children initial Japanese and school-life guidance just before they enter first grade, precisely to close the early language gap that families worry about most. Many Mikawa schools also employ Portuguese-speaking support staff. Our guides to Japanese public school for foreign parents and the school-supplies checklist explain enrollment and the surprising list of items you must buy.

Brazilian schools teach the Brazilian curriculum in Portuguese, keep your child's first language strong, and issue a Brazilian diploma — which matters if the family might return to Brazil. Aichi has among the most Brazilian schools of any prefecture; a 2017 prefectural survey counted 12 schools with 1,155 pupils (676 of compulsory-school age). Two large operators are confirmed still operating: Colegio EAS, run by the Kurahashi Gakuen foundation, which describes itself as Japan's largest Brazilian school, with campuses in Toyohashi, Toyota and Hekinan (plus Hamamatsu, Suzuka and Ota), roughly 1,200 pupils aged 3 to 18, and authorization from both the Japanese and Brazilian governments; and Escola Cantinho Brasileiro in Toyohashi, run by the Toyohashi International Academy foundation. The trade-offs are real: Brazilian schools charge private tuition, and accreditation status varies, which can affect a later transfer into the Japanese system and eligibility for some subsidies. Schools also open and close over the years, so confirm any school's current status, fees and enrollment directly before you count on it.

Babies, child allowance, and children's medical costs

If you are having a baby in Aichi, you register the birth at your city hall within 14 days, add the child to your health insurance and My Number records, and claim the childbirth lump sum through your insurer; our guide to having a baby in Japan as a foreigner lays out the paperwork, and the 2026 changes making childbirth cheaper explain the newest support. Once the child is here, the national child allowance (児童手当) helps with monthly costs — our child allowance guide covers who qualifies, the current amounts and how to claim.

Aichi's cities are generous on children's medical costs, which matters when you have several kids. In Nagoya, the child medical subsidy covers both outpatient and inpatient care up to the end of the fiscal year a child turns 18, with no parental income limit, capping your out-of-pocket cost at ¥500 per medical institution per month. Toyota extended its outpatient subsidy up to high-school age from 1 April 2024. These schemes differ from city to city and are revised often, so confirm the current age limit and any conditions with your own city hall.

Health insurance for the whole family

Health coverage is not optional in Japan, and it is what makes the children's medical subsidy usable. If your employer enrolls you in company health insurance (健康保険), your spouse and children are normally added as dependents (扶養) at no extra premium; if you are self-employed, between jobs, or your workplace does not enroll you, the whole household joins National Health Insurance (国民健康保険) through your city hall. Either way, everyone should be covered from day one — the steps are in our health insurance guide for foreigners and the specifics of adding family members as dependents.

Language at the hospital is a common worry, and Aichi has a concrete answer. The Aichi Medical Interpretation System dispatches trained medical interpreters in 12 languages and offers telephone interpretation in 7, including Portuguese — a genuine safety net when a child is ill and precision matters. For how clinics, referrals and pharmacies actually work day to day, see our guide to Japan's medical system.

Your visa: from 定住者 to permanent residence

For Nikkei families, immigration status usually follows a path from long-term resident (定住者) — the status most Japanese-descent workers hold, which you renew periodically and which lets you work in any field — toward permanent resident (永住者), which removes both the renewals and the work restrictions. Aichi's 104,828 permanent residents (30 June 2025), second only to Tokyo, show how many families complete that journey. Permanent residence generally rewards years of continuous residence with a stable income and a clean tax and pension record, and because the exact requirements change, it is worth reading the current rules carefully; our permanent residence application guide and the PR income requirement explainer cover what to prepare.

Families formed through marriage have their own routes. If you are married to a Japanese national or a permanent resident, see our spouse visa guide and the specialised guide to permanent residence through marriage. Children and non-working spouses of workers usually hold dependent (家族滞在) status; Aichi has 24,447 dependent-status residents (30 June 2025). Because these decisions shape your family's future, it is worth a second opinion — on LO-PAL you can ask a Japanese resident your specific question before you visit the immigration office. Everything is filed at the Nagoya Regional Immigration Services Bureau in Minato Ward, Nagoya, which covers seven central-Japan prefectures including Aichi. Immigration rules can change, so always confirm the latest requirements with the bureau or another official source before you apply.

Driving, licences, and multilingual help desks

Mikawa is car country. Outside central Nagoya, a driver's licence is close to essential for the school run, the supermarket and the commute to the plant, and residents from many countries convert a foreign licence through the gaimen-kirikae process at a prefectural licensing center — a document check and, depending on your country of issue, a knowledge and practical test. Brazilian and Peruvian licence holders go through this route; our Aichi licence conversion guide covers the documents, the translation and what to expect. Qualifying conditions differ by country and are updated from time to time, so check the current rules before you book.

When something does not fit neatly into one office, Aichi has strong multilingual help. The Nagoya International Center (NIC) runs a foreign-resident consultation desk in 11 languages, including Portuguese, on 052-581-0100, and the prefecture's own Aichi Multicultural Center answers in 14 languages on 052-961-7902. Muslim families weighing where to live can also read our guide to Muslim-friendly areas. And if your job or family might take you across a prefectural border, the same industry and communities continue next door: compare our Mie foreign-family guide and, for Shizuoka and its large Hamamatsu Brazilian community, our Shizuoka foreign-family guide. Aichi rewards families who put down roots — low family rents, a deep Portuguese-speaking support system, and a well-worn road from long-term residence to permanent residence — but the specifics vary by city and change often, so treat this guide as your map and confirm the details with your city hall.
