How the system works
Japan reached universal coverage in 1961, and every resident must join a public insurance scheme. Employees join Employees’ Health Insurance, run through their employer or an industry association. The self-employed, retired and others join National Health Insurance, run by municipalities. Premiums are based on income, with employers sharing the cost for employees. There is no opt-out: the system is mandatory, and the schemes together cover the whole population.
The government sets the price of every service and medicine nationally, revising the fee schedule every two years. Providers are mostly private non-profit institutions — hospitals and clinics run by medical corporations — paid by the public insurers under that schedule. Because prices are set centrally, there is no negotiation between insurers and providers over fees, and no surprise billing.
Who pays, and what people pay
Patients pay a share of the cost at the point of use: 30% for most working-age adults, and 10% to 30% depending on age and income — older people pay a lower share. A monthly cap, the high-cost medical expense benefit, limits total out-of-pocket spending: once a household’s payments in a month pass the cap, the excess is refunded, and the cap is lower for older people and people on low incomes. The co-payment is the most visible difference from the other profiles in this set: patients in Japan routinely pay a percentage share of the cost of almost every service.
What is free, and what is not
Nothing is free at the point of use: every visit, test and prescription carries the 10% to 30% co-payment. What the system does instead is cap the cost — the monthly limit means no household faces an open-ended bill — and cover a wide benefits package, including hospital care, outpatient care, medicines, dental care and home care. The trade-off is deliberate: universal coverage with cost-sharing, held affordable by the cap and by nationally set prices.
How it compares
Japan spends 10.6% of GDP on health — above the OECD average of 9.3% — and its life expectancy of 84.1 years is among the highest in this set and 3.0 years above the OECD average of 81.1 years (OECD Health at a Glance 2025). Its distinguishing feature is the combination of mandatory universal insurance, nationally set prices, free choice of provider and routine cost-sharing with a cap.
