Japan's health insurance system is renowned for its universal coverage, providing mandatory coverage for all permanent residents, including foreigners who intend to stay in the country for over three months. The system is primarily funded by taxes and individual contributions, with residents required to enrol in either an employment-based or residence-based health insurance plan. The two main public health insurance plans are the National Health Insurance (NHI) and the Social/Employee Health Insurance (SHI). The NHI covers the self-employed, unemployed, and retired persons under 75, while the SHI is available to those working for Japanese employers, including foreign workers. Japan's health insurance system offers a Free Access System, allowing residents to choose their healthcare providers and frequency of treatment, as long as they hold proof of insurance. An out-of-pocket threshold protects enrollees from excessive costs, with varying co-insurance rates based on age and income. The system also includes advanced treatment hospitals and a focus on preventative care, contributing to Japan's reputation for high-quality medical care and long life expectancy.

What You'll Learn
Mandatory coverage for all permanent residents
Japan's health insurance system provides universal coverage, with mandatory coverage for all permanent residents. This includes Japanese citizens and non-citizens who reside in the country for three months or more. The system is funded primarily by taxes and individual contributions, with residents required to enrol in either an employment-based or residence-based health insurance plan.
The employment-based plans cover about 59% of the population, while the residence-based insurance plans cover 41% of the population. The residence-based National Health Insurance (NHI) system insures the self-employed, unemployed, and retirees under 75. This scheme is administered by municipalities but will transition to prefectural offices in 2018. Enrollees contribute through premiums, with nearly half of the benefit expenditures covered by tax subsidies.
The Citizen Health Insurance plans, a type of residence-based insurance, cater to individuals with lower incomes, such as the unemployed, self-employed, and retirees. Those with moderate incomes who experience sudden income loss are also eligible for reduced mandatory contributions. The Health Insurance for the Elderly plans, another type of residence-based insurance, automatically cover all adults aged 75 and above.
Regardless of the insurance scheme, enrollees are free to choose their healthcare providers and the frequency of treatment. This "Free Access System" allows residents with proof of insurance to receive necessary medical services for a fixed contribution rate. There is an out-of-pocket threshold to protect enrollees from excessive costs, with a monthly average limit of 90,000 yen (approximately $724) for working-age individuals. The threshold and post-threshold co-payment vary based on age and income, ensuring financial risk protection.
Japan's health insurance schemes also cross-subsidize each other to maintain financial stability due to variations in enrollee income levels. The government plays a crucial role in regulating the system, setting fee schedules, and providing subsidies to local governments, insurers, and providers.

Universal healthcare
Japan's healthcare system is highly regarded internationally, and the country has provided universal healthcare since 1961. The system is known as Social Health Insurance (SHI) and is funded primarily by taxes and individual contributions. All citizens and permanent residents of Japan are required to enrol in either an employment-based or residence-based health insurance plan. There are over 3000 health insurance funds divided between three insurance schemes: employer-based health insurance, residence-based National Health Insurance (NHI), and health insurance for persons over 75.
The SHI scheme applies to everyone employed full-time by a medium or large company, with approximately 5% deducted from salaries and matched by employers. Those who are not eligible for SHI, including the self-employed, unemployed, and retired, are covered by the NHI plan. Enrollees contribute to the NHI plan through premiums, with nearly half of benefit expenditures covered by tax subsidies. The amount paid is based on income, with an average limit on out-of-pocket payments of 90,000 yen per month for those of working age.
Regardless of the insurance scheme, Japan's system operates as a Free Access System, where residents are free to choose their healthcare providers and frequency of treatment. Benefit packages are standardised across all plans and include hospital care, outpatient care, mental health care, prescription drugs, home health care, and dental care. Co-insurance rates are set between 10% and 30% depending on age and employment status, with lower rates for young children and low-income older adults. To prevent financial hardship, the High-Cost Medical Expense Benefit System subsidises medical costs above monthly out-of-pocket thresholds.
While Japan's healthcare system is praised for its comprehensive coverage and equitable delivery, it faces challenges due to an ageing population and limited resources. The COVID-19 pandemic, for example, exposed structural problems within the system, particularly regarding hospital wait times and overworked medical staff. Additionally, language barriers can be a significant issue for non-native Japanese speakers, even in large metropolitan areas. Despite these challenges, Japan's universal healthcare system remains a model for providing fair, equal, and inexpensive access to healthcare services.

Public and private insurance
Japan's public healthcare system offers universal healthcare, with high standards of care and lowered medical fees. It is funded primarily by taxes and individual contributions. All citizens and residents of Japan are eligible to use the public system, including foreigners who intend to stay in the country for over three months. However, treatment is not entirely free, and patients are responsible for paying 10%, 20%, or 30% of medical fees, depending on their income level and age. Due to this, most people in Japan carry supplementary private insurance to help cover the remaining costs.
There are eight health insurance systems in Japan, with around 3,500 health insurers. These can be divided into two categories: Employees' Health Insurance and National Health Insurance. Employees' Health Insurance is available to those working for Japanese employers, while National Health Insurance is for the unemployed, self-employed, and students. There is also a separate system of insurance for long-term care, called Kaigo-Hoken, which is run by municipal governments.
Private health insurance in Japan is typically offered as a supplement to life insurance, providing additional income in the event of illness. It can also cover specific medical needs, such as chronic diseases, hospitalization, and cancer treatment. The private insurance sector is growing, with an increasing number of contracts in force. This growth is driven by factors such as epidemiologic shifts, the increasing demand for cancer treatments, and the expansion of advanced medical care services.
While the public system is modern and accessible, it does not fully cover healthcare costs, and most people carry private insurance to supplement their national plans. Private plans often provide additional benefits, such as translation services, which can be helpful due to the lack of English-speaking medical staff in many areas. This combination of public and private healthcare ensures that everyone can access the care they need in Japan.

Cost-sharing and co-insurance
Japan's health insurance system provides universal coverage. The system is funded by taxes, mandatory individual contributions, and out-of-pocket charges. The government covers 70% of all costs, and citizens pay the remaining 30% as coinsurance for most services. This 30% coinsurance rate applies to residents under 70 years of age and those 75 and over but still earning incomes comparable to the current workforce.
For young children under six (before compulsory education), and low-income earners aged 75 and over, the coinsurance rate is set at 10%. For residents aged 70-74, the rate is 20%. These variations in co-insurance rates are designed to protect households from catastrophic medical expenses, ensuring that medical costs do not overburden individuals and families.
The High-Cost Medical Expense Benefit System is a crucial component of cost-sharing and co-insurance in Japan. This system subsidizes medical costs that exceed monthly out-of-pocket thresholds, which are typically set at around 90,000 yen per month for working-age individuals. These thresholds are adjusted based on age and income, with the specific calculation depending on the public health insurance scheme. For instance, in the case of an enrollee under 69 years of age with an income between 3.7 and 7.7 million yen, the monthly maximum payment is calculated as [80,100 yen + (medical costs – 267,000 yen) x 1%].
The Health Insurance Association also provides support for high medical care costs. If an individual's copayment amount becomes high, the Association will pay the amount beyond the Cost-Sharing Maximum Amount, referred to as "High-Cost Medical Care Benefits." This calculation is made on a per-person, per-hospital basis, and it helps ease the financial burden of medical expenses.
It is important to note that Japan has three main public health insurance schemes: employer-based health insurance, residence-based National Health Insurance (NHI), and health insurance for those over 75. The NHI covers the self-employed, unemployed, and retirees under 75, and it is administered at the prefectural and municipal levels. The specific insurance scheme an individual enrols in depends on their employment status, age, and residence.

Healthcare quality and access
Japan's healthcare system provides universal coverage, with residents able to access medical services at any public or private facility. The system is funded primarily by taxes and individual contributions, with patients typically paying 30% of the cost out-of-pocket, and the government covering the remaining 70%. There are no restrictions on access, and enrollees can receive care from any medical provider as frequently as they like.
Japan's healthcare system has been praised for its efficiency and quality. The World Health Report 2000 ranked Japan's healthcare system as the best in the world for overall achievement. The country has a high number of hospitals per capita and a high rate of utilisation, with Japanese people visiting the hospital four times more often than the average American. Japan also has advanced medical technology, with a high per capita rate of CT scans and MRIs. The country has also achieved impressive results in certain areas of healthcare, such as a five-year survival rate of 96.2% for heart transplant recipients between 1992 and 2009, compared to a global average of 71.9%.
However, there are concerns about the quality of healthcare in Japan, particularly in mental healthcare and in rural areas. Japan's psychiatric hospitals have been criticised for relying on outdated methods of patient control, with high rates of compulsory medication, isolation, and physical restraints. There are also significant structural problems within the healthcare system, including sub-standard paediatric emergency healthcare and wide variations in the quality of care between rural and urban areas, and between public and private institutions.
To address these issues, Japan has implemented several measures to improve healthcare quality and access. The Japan Council for Quality Health Care (JCQHC) was established in 1995 to accredit hospitals and improve standards. The council works to develop clinical guidelines and promote patient safety, although it lacks regulatory power to penalise poorly performing providers. The government has also passed the Industrial Competitiveness Enhancement Action Plan, which aims to prevent diseases and improve the quality of medical and healthcare services. Additionally, the Japanese Medical Specialty Board established a new framework for standards and requirements of medical specialty certification in 2018.
