Japan – Health Service

What is the standard of healthcare in Japan?

Japan’s healthcare system regularly earns recognition as one of the finest anywhere in the world, ranking 13th globally in the CEOWORLD 2024 Health Care Index. Access to high-quality treatment is both broad and affordable for virtually the entire population. Life expectancy in Japan stands at 84.1 years — three years above the OECD average — a figure that speaks to the effectiveness of the healthcare system as well as the nation’s deeply ingrained culture of preventive medicine and regular health screening.

Japan records 12.5 hospital beds per 1,000 people, vastly exceeding the OECD average of 4.2, and offers 184 CT scanners, MRI units, and PET scanners per million population, against an OECD average of just 51. This remarkable concentration of diagnostic equipment means specialist investigations are routinely available without the extended waiting times that commonly affect other high-income health systems.

Healthcare professionals train through a nationwide network of institutions, and the mix of university hospitals, specialist facilities of varying sizes, and local clinics found in both urban and rural settings is well coordinated. Major hospitals are furnished with equipment, processes, and clinical expertise comparable to those in other medically advanced regions such as North America and Europe.

Approximately 80% of people in Japan express satisfaction with access to quality medical care, compared with an OECD average of 64%. This strong public confidence reflects a system that, unlike centralised tax-funded models such as the NHS, spreads responsibility across multiple insurers and providers while the government tightly regulates fees and maintains quality standards throughout.

Rural areas tend to experience somewhat worse health outcomes than urban centres, and the scarcity of healthcare providers outside major cities is an ongoing concern. Nevertheless, the universal fee schedule that applies to all insured services helps sustain consistent standards nationwide, and differences in outcomes such as cancer survival and stroke mortality between regions are relatively modest. Expats intending to settle outside large cities are advised to investigate specialist and hospital availability in their chosen locality before making firm plans.

For authoritative assessments of system quality, consult the WHO Japan country profile and the Japan Ministry of Health, Labour and Welfare (MHLW). The OECD Health at a Glance report also provides regularly updated comparative analysis of Japan’s health system performance.

How is healthcare funded in Japan, and is private health insurance necessary?

Japan’s healthcare financing follows the Bismarck social insurance model — a structure shared with countries such as Germany and France — in which funding derives primarily from compulsory contributions paid by individuals and employers, supplemented by general government revenue. This differs both from purely tax-funded Beveridge-style arrangements like the NHS and from market-driven systems reliant on out-of-pocket spending. The result is a system that achieves universal coverage while linking individual premiums to income levels.

Two principal forms of public health insurance exist in Japan. Employees of companies join Employees’ Health Insurance (Kenko Hoken), while the self-employed, unemployed, retired, and students typically enrol in National Health Insurance (Kokumin Kenko Hoken). The Social Health Insurance scheme for employees is funded through payroll contributions shared between employer and employee at roughly 5% each.

Both schemes cover approximately 70% of medical costs, leaving the patient responsible for the remaining 30%. The standard co-payment is 30% for those aged 6–69. Children under six generally pay 20%, those aged 70–74 pay 20% (or 30% for high earners), and those aged 75 and over pay 10% (or 30% for high earners). These rates remain in effect as of 2025.

Significant changes to National Health Insurance caps and rates took effect in 2025. Tokyo’s basic NHI contribution ceiling, for instance, rose to ¥660,000, and several prefectures revised their premium rates upward. As a practical illustration, a single 28-year-old adult in Tokyo with no dependants and annual household income of ¥4,000,000 would pay approximately ¥737,000 per year in NHI premiums in 2025. Because premiums vary by municipality, you should always confirm current figures with your local city or ward office or through the MHLW website.

Enrolment in health insurance is a legal requirement in Japan. Failing to register can prevent visa renewal or changes to residency status, and you remain personally liable for any medical costs incurred while uninsured. A common mistake among new arrivals is overlooking mandatory NHI registration, only to face backdated premium demands covering the months since their residency began. Because enrolment is required from your residency start date, you should complete the process within 14 days of arriving to avoid back-charges.

Although Japan’s universal health insurance provides strong protection, expats may wish to consider supplemental private or international health insurance to cover the standard 30% co-payment, to gain access to private hospitals or English-speaking specialists, to obtain cover for treatments not fully included under public insurance such as certain advanced therapies, and to maintain worldwide coverage for those who travel regularly or anticipate returning to their home country.

How do I register with a doctor or access primary care in Japan?

Primary care in Japan operates quite differently from countries such as Australia or the Netherlands, where patients must formally register with a named GP before accessing the broader health system. In Japan, patients are generally free to walk into any clinic — except those that require appointments — without prior registration at a specific practice. This open arrangement is more flexible but can contribute to congestion at well-regarded clinics.

Primary care settings typically comprise a doctor supported by nursing staff. Although some clinics dispense medication on-site, the broader use of independent pharmacists has been expanding. While the government encourages patients to establish a preferred doctor, there are financial disincentives to bypass that relationship — notably additional charges levied for first consultations at large multi-specialty hospitals when no referral has been made.

Many clinics operate on a walk-in, first-come-first-served basis rather than by scheduled appointments. This means patients may face lengthy waits, particularly at popular practices. Arriving before the clinic opens to obtain a numbered ticket is a common strategy. Larger urban hospitals and international clinics are more likely to offer formal appointment systems and tend to be more navigable for expats unfamiliar with the walk-in model.

When attending a clinic or hospital, you will need to present your health insurance card — or, as of 2024–2025, your My Number Card, which is progressively replacing the traditional insurance card. Standard documentation for initial enrolment includes your residence card and passport. Your insurance card, or its digital equivalent, confirms your participation in Japan’s public health insurance programme and must be shown at every clinic, hospital, or pharmacy visit to receive treatment at insured rates.

To join the National Health Insurance scheme, visit your local city or ward office. The MHLW and the NHI section of your local municipal office are the principal official sources of guidance on enrolment. Many municipalities also publish multilingual information for foreign residents to assist with this process.

What services do hospitals in Japan provide, and what should patients expect?

Hospitals and clinics across Japan offer the full range of healthcare services, encompassing general consultations, specialist treatment, dental care, mental health services, and prescription medications. The government regulates fees tightly to keep care affordable, establishing a uniform national fee schedule that is reviewed on a two-year cycle. This means the cost of treating the same condition is broadly consistent whether you are at a hospital in central Tokyo or a smaller regional city.

Fees for insured treatment under Japan’s public health insurance system are standardised across the country. Patients will encounter broadly comparable costs for the same condition regardless of which facility they attend, though supplementary charges apply for private rooms or services that fall outside the insured framework. Those requesting a private room or additional amenities should anticipate paying more on top of the standard insured rate.

Unlike in certain parts of South and Southeast Asia, or in some Southern European hospital traditions, Japan does not expect family members to take on bedside nursing duties. Hospitals employ their own nursing and care teams to fulfil this role. That said, Japan’s medical culture leans toward formality. Consultations with doctors can be brief, and detailed explanations of a diagnosis or treatment plan are not always offered unless the patient specifically requests them. It is important to ask questions actively and to ensure you clearly understand your condition and the proposed course of treatment.

Recent data indicates that roughly 15% of Japan’s hospitals are owned by central or local government or closely affiliated bodies, with the balance being private and non-profit institutions, some of which receive public subsidies in recognition of their semi-public function. This mixed ownership landscape means that the vast majority of hospitals participate in the public insurance system regardless of who owns them. Private insurance is popular despite the comprehensive public system; however, unlike some other countries, Japan does not maintain a parallel tier of exclusively private hospitals providing exclusively premium services outside the insured framework.

Language can present a genuine obstacle for non-Japanese speakers. Even in major cities, it cannot be assumed that hospital staff will communicate fluently in other languages. Engaging a professional medical interpreter for appointments is strongly advisable, and some international insurance products include translation assistance as part of their coverage.

How does follow-up and aftercare work in Japan?

Post-treatment follow-up in Japan is generally managed through outpatient appointments at the hospital where care was originally delivered, or through referral to a local clinic. There is no automatic GP-based follow-up mechanism of the kind found in many European countries, but hospitals typically schedule outpatient visits before a patient is discharged, and patients may return directly to their treating specialist without requiring an intermediary referral.

Residents aged 75 and over, or those over 65 with a registered disability, are covered under the Long Life Medical Care System (Kouki Koreisha Iryo Seido), which includes provisions for longer-term care and rehabilitation. For those under 75, rehabilitation services are available through hospitals and outpatient facilities and are covered under the standard insurance co-payment structure.

Japan operates a formally established long-term care insurance system (Kaigo Hoken) designed to support older residents who require ongoing nursing or personal care. This scheme is distinct from health insurance and is funded through its own dedicated premiums. Expats aged 40 and above are generally required to enrol and contribute to this programme.

Mental health aftercare represents a meaningful gap in the system. The restricted insurance coverage for psychotherapy limits the number of therapists in practice, and those who do work in this field frequently charge fees that are high relative to other medical services. While basic psychiatric consultations and psychiatric medications are accessible at reasonable cost, the overall quality of mental health provision — particularly access to counselling and community-based support — falls short of what is available in many comparable high-income countries. Expats report that care tends to be strongly medication-focused, and language barriers add further difficulty. Those seeking psychological therapy or counselling in a language other than Japanese will in most cases need to make private arrangements, as such services are rarely accessible through the standard public system.

What are the rules on medical treatment for foreign visitors and new arrivals in Japan?

Short-stay visitors and foreign travellers remaining in Japan for up to 90 days are not eligible for national health insurance but can arrange cover through private travel or international medical insurance. A common misconception among tourists is that their home-country health insurance operates in Japan — it does not. Any visitor without travel insurance is liable to pay the full cost of medical treatment on the spot. While costs in Japan are lower than in some other high-income countries, they remain substantial for anything beyond a simple consultation.

Foreign nationals who hold a residence visa allowing them to remain in Japan for more than three months — as distinct from a tourist visa — are obliged to enrol in either National Health Insurance or the employer-based insurance scheme. New arrivals should treat this registration as a priority and complete it as soon as they receive their Residence Card.

Japan has concluded social security agreements with a number of countries, primarily to prevent workers from making dual contributions to pension and insurance systems simultaneously. These agreements may allow employees seconded from certain countries to remain covered by their home-country scheme rather than enrolling in Japan’s system. However, the scope and standing of these arrangements differ significantly by country and are subject to change. You should verify your particular circumstances directly with the Japan Ministry of Health, Labour and Welfare and the relevant authority in your home country before assuming that any exemption applies to you. Enrolment is mandatory for most residents, though agreements with certain countries may exempt some individuals.

Japan does not operate broad reciprocal healthcare arrangements comparable to the European Health Insurance Card system used among EU member states. All visitors are strongly advised to secure comprehensive travel insurance before entering Japan, and new residents should enrol in public health insurance without delay.

What are the most important health insurance options for expats in Japan?

Expats living in Japan generally have three main insurance routes available to them: employer-provided Social Health Insurance (SHI), the National Health Insurance (NHI) scheme, and private or international health insurance as a standalone or supplementary product. Establishing which option applies to your circumstances before arriving is essential.

Employees’ Health Insurance (Shakai Hoken) is available to company employees, with premiums split between the employer and employee. It encompasses health, pension, and unemployment coverage. National Health Insurance (Kokumin Kenko Hoken) is intended for everyone else — the self-employed, students, and non-working household members — with premiums calculated in full according to the policyholder’s income and household composition. Both programmes deliver broadly equivalent healthcare coverage; the key distinction is that NHI is administered by local government, while SHI operates through your employer’s designated insurance provider.

Private health insurance can be taken out to supplement the coverage already provided by public schemes. International health insurance policies are a popular choice among expats for the comprehensive, globally portable benefits they offer — an important consideration for those who travel often or anticipate relocating to another country in the future.

When assessing international health insurance products, expats should pay close attention to: whether the policy covers the 30% standard co-payment; access to hospitals with multilingual staff; whether the insurer has direct billing arrangements with Japanese hospitals; the treatment of pre-existing conditions, which differs considerably between providers; and whether the policy remains valid globally if you travel or move again. Always verify the current premium costs and exact policy terms with your chosen insurer, and confirm that the insurer is authorised to conduct business in Japan through the Japan Financial Services Agency (FSA), which regulates insurance providers operating in the country.

NHI premiums are recalculated each fiscal year based on the prior year’s income and household composition. Newly arrived foreign nationals may initially be assessed at lower estimated premium rates until complete tax data becomes available. Confirm current rates with your local ward office or the MHLW, as figures are revised annually.

Are there any particular health risks or considerations for people moving to Japan?

From a public health standpoint, Japan is a very safe country in which to live. Food and water safety standards are high, sanitation is excellent, and the national disease surveillance infrastructure is sophisticated. Tap water is safe to drink throughout the country. Nevertheless, several health considerations are worth understanding before relocating.

Japan’s healthcare culture places a strong emphasis on prevention, with early detection and routine check-ups forming a cornerstone of the system. This approach contributes meaningfully to the population’s long life expectancy. New residents are encouraged to take part in annual health screening programmes (ningen dock and kenko shindan), which are often partially subsidised or covered under health insurance.

Japan carries several seasonal health risks. Cedar pollen (kafunsho) affects a large share of the population each spring and can trigger severe hay fever in people who have never previously experienced allergic rhinitis. Japanese encephalitis, while uncommon, is present in some rural areas, and vaccination is recommended for those intending to live in the countryside long-term. Tick-borne diseases such as scrub typhus are present in certain parts of the country. Japan is also an earthquake- and typhoon-prone nation, and natural disasters including tsunamis are a genuine feature of daily life. Expats should acquaint themselves with their municipality’s emergency preparedness protocols.

Air quality in Japan’s major cities is generally favourable by international standards, though fine particulate matter (PM2.5) concentrations can rise during certain seasons, partly as a result of seasonal dust arriving from the Asian continent. Those with respiratory conditions should monitor local air quality alerts, which are published by municipal authorities.

Mental health provision is a genuine concern. Restricted insurance reimbursement for psychotherapy limits the number of practising therapists, and while basic psychiatric consultations and medications are accessible, the availability of counselling and community-based mental health support lags behind that of many comparable countries. Expats dealing with depression, anxiety, or the difficulties of cultural adjustment may find affordable, linguistically accessible psychological support hard to obtain through the public system and should explore private options before moving. Organisations such as TELL Japan (telljp.com) offer multilingual mental health support services to foreign residents in Japan.

Before relocating, consult the WHO Japan country profile and your own national travel health advisory body — such as the CDC for US residents, the UK NHS Travel pages, or the equivalent authority in your country — for the most current vaccination recommendations and health advisories relevant to Japan.

Frequently asked questions about healthcare in Japan

Can I use Japan’s public health system as an expat?

All residents of Japan — including foreign nationals intending to remain in the country for more than three months — are eligible to use the public healthcare system. You must enrol in either Employees’ Health Insurance (if you are employed by a Japanese company) or National Health Insurance (if you are self-employed, a student, or not working) within 14 days of receiving your Residence Card. Not registering promptly can lead to backdated premium demands and complications when renewing your visa. Confirm enrolment requirements with the MHLW or your local ward office.

How do I find a doctor who can communicate in languages other than Japanese?

Efforts to improve the situation include encouraging healthcare workers to undertake medical translation training, hiring professional interpreters and patient coordinators at a growing number of hospitals, and expanding medical English instruction in medical school programmes. Major international hospitals in cities such as Tokyo, Osaka, and Nagoya — including St. Luke’s International Hospital in Tokyo — commonly employ multilingual staff. The JNTO (Japan National Tourism Organization) and many municipal governments publish directories of hospitals offering foreign language support. Translation apps and professional medical interpreters can also provide practical assistance at clinics that lack multilingual staff.

What happens in a medical emergency in Japan?

In an emergency, dial 119 to request an ambulance (kyukyu-sha). Ambulance services are provided free of charge at the point of use. You will be transported to an appropriate emergency facility, where treatment will be given regardless of your insurance status. On discharge, you will be required to pay your co-payment — typically 30% as of 2025 for those aged 6–69 — and any costs not covered by insurance. Uninsured patients will be billed for the entire cost of treatment. Always carry your insurance card or My Number Card whenever you leave home.

How do prescriptions work in Japan?

Although some clinics dispense medication directly, the independent pharmacy sector (yakkyoku) has grown substantially. In many cases, your doctor will issue a prescription slip (shohosen) for you to take to a pharmacy, where you pay the relevant co-payment on the medication — ordinarily 30% of the insured price as of 2025. Prescription drugs covered under public insurance are priced according to the government’s official drug tariff. Note that some medications available over the counter abroad require a prescription in Japan, and the reverse is also true. Expats who rely on regular medication should bring an adequate supply along with a letter from their home-country doctor, and arrange a consultation with a Japanese physician to obtain a local prescription.

Are pre-existing conditions covered by Japan’s public health insurance?

Japan’s public health insurance programmes — both NHI and Employees’ Health Insurance — do not as a rule exclude pre-existing conditions, in contrast to many private insurance products. Once you are enrolled, you are entitled to receive treatment for existing health conditions under the standard co-payment structure. Certain specific treatments, including some advanced therapies and elective procedures, may fall outside the scope of public insurance and would require out-of-pocket payment or supplemental private cover. For confirmation of coverage for particular conditions, contact the MHLW or your local insurer directly.

What is the ‘high-cost medical expense benefit’ (Kogenryo) and does it apply to expats?

Japan’s high-cost medical expense benefit (Kogenryo Ryoyohi Kyufu) is a crucial safety net for insured residents. It sets a ceiling on the out-of-pocket amount any insured person is required to pay within a single calendar month, ensuring that even serious or prolonged illness does not result in financial ruin. If you are anticipating expensive surgery, you can apply for an advance certificate so that the hospital charges only up to the capped amount at the time of treatment. The monthly ceiling varies by income band and is reviewed regularly by the MHLW; check the current thresholds with your insurer or ward office.

Does Japan have reciprocal healthcare agreements with other countries?

Japan has entered into social security agreements with a number of countries, principally to prevent workers from being required to contribute simultaneously to pension and insurance schemes in both Japan and their home country. However, these arrangements are limited in scope and do not function in the same way as the European Health Insurance Card framework used across EU member states. The majority of foreign nationals are required to enrol in Japan’s public health insurance upon completing three months of residency, irrespective of nationality. In some cases, bilateral agreements may exempt certain individuals from this obligation. You should verify whether any such agreement applies to your specific nationality and situation by consulting the MHLW and the relevant authority in your home country before assuming you qualify for an exemption.

What healthcare is available to tourists and short-stay visitors in Japan?

Foreign travellers and short-term visitors staying in Japan for up to 90 days are not eligible for national health insurance cover but may purchase travel or international private medical insurance through private providers. Visitors without insurance must pay the full cost of any medical treatment out of pocket at the time of receiving it. Even a straightforward GP-equivalent consultation can amount to several thousand yen; more serious treatment will be considerably more expensive. Comprehensive travel insurance that covers medical expenses and emergency repatriation is strongly recommended for all visitors to Japan.
