Health Insurance for Japanese Expats in the Netherlands
Moving from Japan to the Netherlands? Your Japanese health insurance card isn't valid here. Learn what Dutch health insurance costs, how enrollment works, and key differences from Kokumin Kenko Hoken and Kenpo.
Japan to the Netherlands: Two Mandatory Systems, One Important Difference
Japan and the Netherlands have something important in common: both countries operate mandatory universal health insurance systems. If you've been covered under Kokumin Kenko Hoken (国民健康保険, National Health Insurance) or Kenpo (健康保険, employee health insurance / Shakai Hoken), you already understand the logic of compulsory insurance. The Dutch system shares that philosophy.
But the mechanics are different enough to cause real confusion — and real gaps in coverage if you don't act quickly.
The essential fact: your Japanese health insurance is not valid in the Netherlands. Your 保険証 (health insurance card) cannot be presented at a Dutch GP or hospital. There is no bilateral agreement between Japan and the Netherlands that coordinates health insurance for residents. Once you register as a resident in the Netherlands, you must take out Dutch health insurance (zorgverzekering) — regardless of what Japanese coverage you hold or continue to pay into.
Who Must Have Dutch Health Insurance?
You need Dutch health insurance if you:
- Are registered as a resident in the Netherlands (at the gemeente/municipality)
- Work in the Netherlands under any employment contract
- Are posted to a Dutch office by a Japanese company
- Are a highly skilled migrant (kennismigrant) registered in the Netherlands
- Are a student enrolled at a Dutch institution with a long-stay visa
- Are a dependent family member registered at the gemeente
This covers the broad range of Japanese expats in the Netherlands: corporate assignees at Japanese companies with European operations, engineers and researchers in technology and life sciences, academics at Dutch universities, and family members accompanying them. The Randstad — Amsterdam, Rotterdam, The Hague, and Eindhoven — has a significant Japanese expat community and the infrastructure to support it.
The Enrollment Timeline
| Step | Timeline |
|---|---|
| Arrive in the Netherlands | Day 0 |
| Register at gemeente → receive BSN | First priority — aim for week 1 |
| Enrol in Dutch health insurance | Within 4 months of gemeente registration |
| Apply for zorgtoeslag | As soon as you have your BSN |
| Miss deadline | CAK assigns an insurer and adds a surcharge fine |
The BSN (Burgerservicenummer) is your citizen service number — the administrative key to life in the Netherlands. Without a BSN, you cannot enrol with any Dutch health insurer, open a Dutch bank account, or access most services. Registering at the gemeente is always the first administrative step.
If you miss the 4-month enrollment window, the CAK (Centraal Administratie Kantoor) will assign you to an insurer automatically — and charge a surcharge for the uninsured period. Enrol promptly to avoid this entirely.
What Dutch Basic Insurance Covers
Dutch basic insurance (basisverzekering) is standardised by law. Every insurer offers the same core package — you are comparing on price, service quality, app functionality, and plan type (more on that below). For 2025:
- Premium: approximately €135–€160/month
- Deductible (eigen risico): €385/year
- GP visits (huisarts): always free — no deductible, no co-pay
The basic package covers:
- GP (huisarts) consultations — free, always
- Hospital care and specialist treatment (after GP referral)
- Prescription medication (approved formulary)
- Mental healthcare (GGZ) — up to 3 years per condition
- Maternity and obstetric care
- Medical aids (limited categories)
- Emergency care
Children under 18 pay no premium and have no deductible — all their care is free at point of use.
The Deductible (Eigen Risico): Different from Japan's 30% Co-Pay
This is one of the most important structural differences between the Japanese and Dutch systems — and one that surprises many Japanese expats.
Japan's model: You pay 30% of the cost of each healthcare service as a co-payment (自己負担). This applies to most GP visits, specialist visits, hospital stays, and prescriptions. The remaining 70% is covered by your insurer (Kenpo or Kokumin Kenko Hoken). For high-cost care, Japan's High-Cost Medical Expense System (高額療養費制度) caps your monthly out-of-pocket costs.
The Dutch model: Instead of a percentage co-pay, the Netherlands uses a flat annual deductible — the eigen risico of €385 in 2025. You pay the first €385 of eligible healthcare costs per calendar year yourself. After you've reached €385, your insurer covers 100% (within the covered package). The deductible resets on 1 January each year.
Critically, GP visits do not count toward the deductible. GP consultations are always free — no co-pay, no charge, ever. This is different from Japan, where GP or clinic visits typically involve a 30% co-payment.
You can choose to voluntarily increase your deductible (up to €885/year) in exchange for a lower monthly premium — useful if you are healthy and expect few specialist visits.
Japanese vs Dutch Healthcare: A Side-by-Side Comparison
| Feature | Japan (Kenpo/Kokumin Kenko Hoken) | Netherlands |
|---|---|---|
| Insurance type | Employer (Kenpo) or municipal (Kokumin) | Individual private insurer, mandatory |
| Monthly premium | Income-based; employer contributes | €135–€160/month; paid directly by you |
| Government subsidy | Employer contribution; municipal subsidy | Zorgtoeslag (up to €127/month) |
| Co-pay model | 30% of each service cost | Flat €385/year deductible (not per-visit) |
| GP gatekeeper | No — direct specialist booking is common | Yes — huisarts referral required always |
| Specialist access | Direct booking at clinics/hospitals | Referral from huisarts required |
| High-cost protection | 高額療養費 (monthly cap system) | €385 annual deductible cap |
| Insurance card | 保険証 (health insurance card) | Digital records; app-based verification |
| Dental | Partially covered (30% co-pay) | Not covered in basic; supplementary available |
| Children under 18 | Covered (co-pay applies) | Free — no premium, no deductible |
| Prescription | 30% co-pay | Covered after deductible |
The Huisarts: A Key Structural Difference
This is the adjustment that most consistently surprises Japanese expats — and it is important to internalise before you need healthcare.
In Japan, it is normal to book appointments directly with clinics or hospital outpatient departments (外来). You might visit an internal medicine clinic (内科), a dermatology clinic (皮膚科), or a hospital's specialist department based on your own assessment of your symptoms. The gate-keeping layer of a mandatory GP referral does not exist in the same way.
In the Netherlands, this model does not apply. The huisarts (GP/family doctor) is the mandatory entry point to all non-emergency specialist care. You cannot book directly with a dermatologist, cardiologist, gynaecologist, or any other specialist. You must first see your huisarts, who will refer you if appropriate.
Dutch GPs are highly trained generalists. The Dutch system is designed around the philosophy that most medical concerns can and should be handled at GP level — and the data supports this. Referral rates are kept deliberately low because it reduces costs and avoids unnecessary specialist interventions.
What this means practically:
- Register with a huisarts practice in your first week in the Netherlands, before you need one. Practices have registration capacity limits and can decline new patients.
- Your huisarts visit is always free — no charge, no deductible.
- If you go to a hospital's outpatient department without a GP referral (outside of genuine emergencies via 112), you may be turned away or billed at full cost without insurer reimbursement.
- In Amsterdam, Rotterdam, The Hague, and Eindhoven, many huisarts practices serve international patients and offer consultations in English.
The Dutch GP is a generalist — they do not specialise in a particular organ system or condition in the way Japanese clinics often do. This can feel less specialised than a Japanese クリニック, but Dutch GPs manage a wide range of conditions effectively and refer when genuinely necessary.
Japanese Insurance and Shakai Hoken: What Doesn't Transfer
| Japanese coverage type | Valid in Netherlands? |
|---|---|
| Kokumin Kenko Hoken (国民健康保険) | No |
| Kenpo / Shakai Hoken (健康保険) | No |
| Company group health plan | No |
| Japanese company expat group extension | No — cannot legally replace Dutch insurance |
| Japanese travel insurance | No — not for residents |
| JEES or other international school plans | No |
Japanese companies with Netherlands operations — Toyota Tsusho Europe, Fujitsu, Sony, Canon, and many others — often maintain comprehensive employee health management (健康管理) programmes. These may include annual health check-ups (健康診断), corporate wellness programmes, and Japanese-language support. These programmes do not substitute for Dutch zorgverzekering. Employees posted to the Netherlands must hold Dutch health insurance.
Some Japanese insurers offer travel or expat extensions to group plans for assignees working abroad. These can supplement Dutch insurance — for example, providing Japanese-language claims support or covering care when you travel back to Japan — but they cannot legally replace the Dutch basic insurance requirement.
Zorgtoeslag: Government Premium Support
The Dutch government subsidises health insurance premiums for lower and middle-income residents through zorgtoeslag (healthcare allowance).
For 2025, single people earning under approximately €38,520/year may receive up to €127/month toward their monthly premium. The benefit is income-tested — higher earners receive a lower subsidy or none at all.
For Japanese expats on typical corporate assignee salaries, zorgtoeslag eligibility is less common. However, researchers, students, early-career professionals, and some part-time workers may well qualify. Apply at Belastingdienst.nl as soon as you have your BSN. It takes only a few minutes and can be backdated to the start of the calendar year.
Dental: An Important Difference from Japan
Dental care is one of the most significant coverage gaps for Japanese expats moving to the Netherlands, and it is worth planning for.
In Japan, routine dental care — examinations, cleanings, fillings, extractions — is covered by national health insurance with a standard 30% co-pay. Dental treatment at licensed Japanese dental clinics is relatively affordable because insurance absorbs 70% of the cost.
In the Netherlands, adult dental care is not covered by basic insurance. Routine dental check-ups, fillings, crowns, and most dental procedures are paid entirely out-of-pocket unless you have supplementary insurance.
Dutch dental costs without insurance are not trivial. A routine check-up and clean costs roughly €50–€100; a filling can cost €50–€150; more complex work is proportionally more expensive.
Supplementary dental insurance (aanvullende verzekering — tandzorg module) is strongly recommended for Japanese expats accustomed to covered dental care. Dental supplementary plans typically cost €15–€30/month and cover a significant portion of routine dental costs up to an annual maximum.
Note: children up to age 18 do have dental care covered under the Dutch basic insurance package, including the check-up, so you do not need supplementary dental insurance for your children.
Supplementary Insurance: Filling the Gaps
Beyond dental, the basic package leaves several areas uncovered:
| Not covered in basic | Supplementary option |
|---|---|
| Adult dental (routine, fillings, crowns) | Tandzorg module, ~€15–€30/month |
| Physiotherapy (beyond session allowance) | Add-on module, ~€5–€15/month |
| Glasses and contact lenses | Included in many supplementary plans |
| Alternative medicine / acupuncture | Select plans |
| Extended mental health beyond GGZ | Some plans |
For families with children, remember that children's dental and most children's care are fully covered in the basic package at no premium — a genuinely family-friendly feature of the Dutch system.
Natura vs. Restitutie: Choosing Your Plan Type
Dutch insurers offer two main plan structures:
Natura (in-network) plans:
- Insurer contracts with specific hospitals and specialists
- Lower monthly premium
- Care outside the contracted network may not be fully reimbursed
- Good choice if you are happy to use your insurer's contracted network
Restitutie (reimbursement) plans:
- Higher monthly premium
- You can see any licensed Dutch provider
- Insurer reimburses you at the market rate for any care
- More flexibility — preferred by many expats who want to choose their own providers
For Japanese expats who want to choose English-speaking specialists, use specific hospitals in the Randstad, or prefer maximum flexibility in a new country, a restitutie plan is typically the better choice. The premium difference is modest — typically €10–€20/month — and the flexibility is worth it when you are still learning the system.
Finding English-Speaking Healthcare in the Netherlands
The Japanese expat community in the Netherlands is concentrated in the Randstad: Amsterdam, Rotterdam, The Hague (Den Haag), and Eindhoven. In all of these cities, English-speaking huisarts practices are widely available.
Tips for finding an English-speaking GP:
- Search Zorgkaart Nederland (zorgkaartnederland.nl) by postcode — many practices indicate the languages spoken by their doctors
- Ask your employer's HR or expat services team — companies with Japanese assignees often have relationships with specific practices
- Japanese community organisations and Facebook groups (e.g., Expatriates in Amsterdam/The Hague) maintain informal lists of recommended English or Japanese-speaking GPs
- The Japanese Embassy in The Hague maintains a list of doctors in the area
Japanese-language support: Some medical interpreting services operate in the Randstad and can accompany you to hospital appointments. International hospitals (like the Hospital VU and Erasmus MC in Rotterdam) often have international patient services with multi-language support.
Annual Health Check-Ups (健康診断) in the Netherlands
Japanese corporate culture places great importance on the annual health check-up (健康診断 / 人間ドック). In Japan, employers are legally required to provide annual health screenings to full-time employees, covering blood tests, blood pressure, BMI, and other standard measures.
In the Netherlands, there is no equivalent statutory employer health check-up requirement. Some Dutch employers or Japanese companies with Dutch operations do offer optional health screening, but it is not universal.
Standard annual check-ups are not covered by Dutch basic insurance as a routine preventive benefit. However, your GP can order blood tests, blood pressure monitoring, and other tests when there is a clinical reason — and these will be covered (after your deductible). For the comprehensive annual check-up that Japanese expats are used to, you may need to seek this privately or through employer programmes.
Common Mistakes Japanese Expats Make
1. Presenting their Japanese health insurance card at a Dutch provider. The 保険証 (health insurance card) has no validity in the Netherlands. Dutch GPs and hospitals have no system to process it, and you will be billed as an uninsured patient if you cannot demonstrate Dutch insurance.
2. Assuming the company's Japanese health management programme covers Dutch healthcare. Japanese corporate health programmes (健康管理) run by Japanese companies for Netherlands-based employees do not substitute for Dutch zorgverzekering. All employees registered as residents must hold their own Dutch health insurance.
3. Going directly to a hospital without a GP referral. The impulse to go directly to a hospital's outpatient department — normal in Japan — will either be refused or result in uncovered costs in the Netherlands. Always start with your huisarts, unless it is a genuine emergency (call 112).
4. Not enrolling in Dutch insurance promptly. The 4-month window from gemeente registration seems generous, but administrative delays in arriving, finding housing, and settling in can make it slip. Set a calendar reminder for the 4-month mark immediately.
5. Not accounting for dental costs. Japanese expats accustomed to affordable dental care with 30% co-pay are sometimes caught off-guard by full out-of-pocket costs in the Netherlands. Get dental supplementary insurance.
6. Not registering with a GP practice early. Dutch GP practices — especially in major cities — fill up. Register in your first week, before you need an appointment.
7. Forgetting to apply for zorgtoeslag. Even if you think you earn too much, check the Belastingdienst threshold using your actual taxable income. Researchers, early-career professionals, and some part-time workers qualify.
Frequently Asked Questions
Is my Japanese health insurance card (保険証) valid in the Netherlands?
No. Your Japanese health insurance card — whether from Kokumin Kenko Hoken, Kenpo, or any Japanese insurer — is not valid in the Netherlands. Dutch healthcare providers have no mechanism to accept Japanese insurance, and there is no bilateral agreement between Japan and the Netherlands for health insurance coordination. You must take out Dutch zorgverzekering once you register as a resident.
How does the Dutch deductible (eigen risico) compare to Japan's 30% co-pay?
In Japan, you pay 30% of the cost of each healthcare service — so costs scale with how much care you use. In the Netherlands, you pay a flat annual deductible of €385, regardless of how many services you receive. Once you've paid €385 in a calendar year, your insurer covers 100%. GP visits never count toward the Dutch deductible and are always free. For people with frequent healthcare needs, the Dutch flat deductible can be more predictable than Japan's percentage model.
My Japanese company posted me to the Netherlands — does the company's health insurance cover me here?
No. Japanese corporate health plans and employer-linked Kenpo schemes are valid only within the Japanese healthcare system. If you are registered as a resident in the Netherlands, you must hold Dutch zorgverzekering regardless of your employer's Japanese coverage. Some Japanese companies with Netherlands postings do provide Dutch health insurance or a premium contribution as part of the assignment package — check your posting letter and HR contact.
Can I find a Japanese-speaking doctor or medical interpreter in the Netherlands?
English-speaking GPs and specialists are widely available in the Randstad. For Japanese-language support, some medical interpreting services operate in Amsterdam, The Hague, and Rotterdam, and can accompany you to specialist appointments. The Japanese Embassy in The Hague publishes a medical reference list for residents. Japanese expat community groups on Facebook and LINE also share recommendations for Japanese-speaking or Japanese-friendly medical providers.
Is dental care covered by Dutch health insurance?
Adult dental care is not covered by the basic insurance package. Routine check-ups, fillings, crowns, and most dental treatment are fully out-of-pocket unless you purchase supplementary dental insurance (aanvullende verzekering, tandzorg module), which typically costs €15–€30/month. This is a significant difference from Japan, where dental care is partially covered with a 30% co-pay. Children under 18 do have dental care covered in the basic package. Get dental supplementary insurance if you want coverage comparable to what you had in Japan.
What is zorgtoeslag and do I qualify?
Zorgtoeslag is a monthly government subsidy to help cover health insurance premiums, paid to lower and middle-income residents. In 2025, single people earning under approximately €38,520/year may receive up to €127/month. Apply at Belastingdienst.nl with your BSN. Eligibility is based on your actual taxable income in the Netherlands. Many corporate assignees exceed this threshold, but researchers, students, and lower-income expats often qualify.
Can my family members use my Dutch insurance?
Each family member registered in the Netherlands needs their own Dutch health insurance. Children under 18 are enrolled for free — no premium, no deductible for any of their care. Your spouse or partner needs their own separate policy. Enrol dependents as soon as they register at the gemeente to ensure they are covered within the 4-month window.
What is open enrollment, and when can I switch insurers?
The annual open enrollment period in the Netherlands runs from 1 November to 31 December each year. During this period you can switch to a different insurer, and any new policy takes effect on 1 January of the following year. Outside this window, you generally cannot switch — unless you have a specific life event (such as moving to a new area or your insurer changing its network). If you are newly arriving in the Netherlands, you are not bound by the open enrollment calendar — you enrol as a new resident at any time within your 4-month window.
