Since medical services vary significantly from country to country, many people may feel, “I’m not sure how Japan differs from other countries.” This confusion is especially common for visitors from abroad, as differences in out‑of‑pocket medical expenses and the structure of hospitals compared to one’s home country can be bewildering. To understand Japan’s healthcare system better, it’s important to compare it with those of other countries.
In this article, we organize the characteristics and quality of Japan’s healthcare services and introduce how they differ from those in major countries such as the U.S., U.K., France, and Germany. We hope you find this article helpful in accessing reliable medical care in Japan with confidence.
Supervising Physician: Y.I., M.D.
honed his expertise in internal medicine through training at several hospitals across Tokyo. He subsequently served in an advanced emergency and critical care center, treating numerous severely ill patients, and continues to work at the forefront as an emergency physician. In addition, he serves as an occupational health physician for corporate clients, engaging in a wide range of health management activities. Drawing on his extensive clinical experience, Dr. Y.I. possesses comprehensive knowledge spanning general outpatient care to emergency medicine.
Characteristics of Japan’s Healthcare Services
A defining feature of Japan’s healthcare system is its universal health insurance coverage—“kokumin kenkō hoken seido”—which ensures that all citizens are enrolled in health insurance. Presenting an insurance card allows citizens to access public coverage at any medical institution nationwide, securing so‑called “free access.” Patients typically pay 30% of medical costs out of pocket, with reduced rates of 10%–20% applied to certain elderly individuals and those with higher incomes, making insured treatments relatively affordable.
Additionally, Japan provides a high-cost medical care benefit program whereby costs above a set threshold are reimbursed, alleviating financial burden in high‑cost cases. Another notable feature is the Maternal and Child Health Handbook system, which offers continuous support throughout pregnancy, childbirth, and early childcare.
In practice, Japanese healthcare emphasizes team‑based care, where doctors, nurses, pharmacists, rehabilitation staff, radiological technologists, and nutritionists collaborate to provide patient‑centered services. Compared to many other countries, patient wait times tend to be shorter, and high medical standards and safety are consistently maintained.

The Quality of Japan’s Healthcare Services
Japan’s healthcare services are supported by the universal health insurance system and are internationally recognized as being of a high standard.
In fact, Japan is one of the countries with the longest life expectancy in the world. According to statistics from the Ministry of Health, Labour and Welfare in 2023, the average life expectancy was 81.09 years for men and 87.14 years for women. An OECD international comparison reported in 2022 also highlighted that Japan consistently ranks among the top member countries in terms of longevity.
Furthermore, Japan is highly regarded for its internationally low mortality rates from cancer, cardiovascular diseases, diabetes, infant mortality, and medical accidents. Progress has also been made in addressing mental health and musculoskeletal disorders. With the development of rehabilitation and mental healthcare systems, efforts are underway to improve patients’ quality of life.
Thus, Japan’s healthcare is internationally trusted not only for extending life expectancy but also for its low mortality rates across a wide range of diseases and its commitment to patient safety, making it a system that draws global attention.

How Japan’s Healthcare Differs from Overseas
Let’s now explore how Japan’s medical services compare with those in other countries:

Healthcare Services in the United States
Healthcare services in the U.S. are divided into public health insurance programs (1), such as Medicare for people aged 65 and older, and Medicaid for low-income individuals. Other people are required to enroll in private health insurance (2), but a significant number remain uninsured. Those without insurance often face extremely high medical costs, sometimes amounting to millions of yen. For example, hospitalization for an appendectomy is said to cost between 2 million and 6 million yen.
In contrast, Japan has a universal public health insurance system, and the same surgery would typically cost patients about 300,000 yen out of pocket. This highlights the large gap in personal healthcare costs between Japan and the U.S.
(1) Public health insurance: A system in which part of the medical expenses is covered by public institutions when a person becomes ill or injured.
(2) Private health insurance: A system in which insurance companies, such as life or casualty insurers, cover part of the medical expenses.

Healthcare Services in the United Kingdom
The UK’s healthcare services are funded through a tax-based system. At national hospitals, patients generally do not pay out-of-pocket for medical services. However, for treatments that are not urgent, patients may have to wait several months. In addition, the UK operates a general practitioner (GP) system, requiring patients to first see their registered GP, who then provides referrals to specialists.
In Japan, such a system does not exist, and patients are free to directly consult the medical institution or specialist of their choice.

Healthcare Services in France
France, like Japan, has a universal health insurance system. However, it operates a GP system where patients are expected to first consult their registered family doctor. While it is possible to see a specialist directly, doing so results in higher out-of-pocket expenses.
In Japan, patients can freely choose to consult specialists without such restrictions, marking a major difference between the two systems.

Healthcare Services in Germany
In Germany, while enrollment in public health insurance is not legally mandatory, over 80% of citizens are covered by it. The rest are enrolled in private health insurance, creating a system that closely resembles universal coverage. Although there is no legal requirement to have a family doctor, about 90% of the population does, and it is common practice to regularly consult a trusted physician.
In Japan, having a family doctor is recommended, but many patients still choose freely among medical institutions, which distinguishes it from Germany.

Healthcare Services in China
China also operates a universal health insurance system. However, coverage differs depending on household registration status and employment, which affects both eligibility and out-of-pocket expenses. Furthermore, receiving treatment outside the region where premiums are paid often requires patients to cover the full cost. Medical expenses also vary greatly depending on the hospital’s rank.
In Japan, patients can use their insurance card anywhere in the country, regardless of location or hospital rank, which is a key difference from China.

Healthcare Services in Australia
Australia’s healthcare system is supported by a tax-funded program called “Medicare,” which covers most hospitalization and consultation costs at public hospitals. However, if patients request treatment from a specific doctor, they must cover 25% of the cost themselves. Another feature is the “general practitioner system,” where patients must first see a GP and then receive a referral to a specialist.
In Japan, there are no additional costs for selecting a doctor, and patients may directly choose specialists, which differs from the Australian system.

Healthcare Services in Thailand
Thailand has both public and private health insurance systems, with the majority of citizens covered by public insurance. Public health insurance is divided into three programs depending on occupation and employment type. While all citizens are covered by one of these schemes, unlike in Japan, co-payment rates do not vary by age.
In Japan, co-payment rates vary between 10–30% depending on age and income.

Healthcare Services in Malaysia
Malaysia operates a dual system of public and private health insurance. Public insurance, funded by taxes, keeps patient costs low but often involves long wait times for consultations and hospital admissions. On the other hand, private insurance offers advanced facilities and comfortable services with shorter waiting times, but at higher costs.
In Japan, there is little cost disparity between public and private hospitals, and patients can use public health insurance at any institution, which differs from Malaysia.

Healthcare Services in Singapore
Singapore’s healthcare system is supported by the compulsory “Central Provident Fund (CPF)” scheme. Citizens with income above a certain threshold are required to participate, contributing to a medical savings account, as well as separate accounts for housing, education, and retirement.
This system requires individuals to prepare financially for healthcare and future living expenses. In contrast, Japan does not impose compulsory savings; instead, citizens pay monthly insurance premiums and use their health insurance card to cover a fixed share of medical costs.
Healthcare Services in India
India does not have a universal health insurance system. Public insurance programs cover only certain workers and impoverished groups, who may receive treatment without co-payments at registered facilities. Some people have private health insurance, but many lack coverage altogether, leading to large disparities in access to medical services.
In Japan, universal health coverage ensures that all citizens have fair access to public healthcare services, which sharply contrasts with the situation in India.

Healthcare Services in Taiwan
Taiwan operates under the “National Health Insurance” system, a public scheme managed by the government as a single insurer. Foreign residents staying for a certain period are also eligible. Patients present an IC chip health insurance card for treatment, and co-payment rates are relatively low compared with other countries.
Japan also has universal health coverage, but its system is run by multiple insurers such as “National Health Insurance” and “Employee’s Health Insurance,” rather than a single unified scheme like Taiwan’s.
Healthcare Services in Hong Kong
Hong Kong does not have public health insurance like Japan, and healthcare is essentially provided on a fee-for-service basis. As a result, many people purchase private health insurance to prepare for high medical costs. Although public hospitals offer subsidized, low-cost care, overcrowding often leads to long waiting times, with surgery appointments sometimes delayed for months.
In Japan, universal health insurance allows patients to receive care at both public and private hospitals under the same conditions, making the system significantly different from Hong Kong in terms of both structure and costs.
Japan’s Healthcare: High Global Standards
Japan’s universal health insurance ensures accessible, high-quality care for all residents, with strong affordability and accessibility.
