Guide to getting health insurance in Japan in 2026

Healthcare systems vary significantly across countries in terms of access, quality, cost, and how you register with medical providers. Understanding how to access healthcare in your new country, including insurance requirements and registration procedures, is critical for your health and safety abroad.

Understanding Japan's Healthcare System in 2025

Japan ranks among the world's best healthcare systems, known for cutting-edge medical care and one of the longest average lifespans globally. Whether you're moving to Japan for work, study, or retirement, understanding health insurance requirements is essential for accessing this renowned universal healthcare system. While all long-term residents qualify for public health coverage, most also invest in private plans for shorter wait times and English-speaking doctors.

Who Needs Health Insurance in Japan?

Everyone residing in Japan needs health insurance coverage. Long-term residents or anyone staying longer than three months must enroll in public health insurance. This requirement applies to all long-stay visa holders entering Japan.

What happens if you don't have health insurance in Japan? Without coverage, you must pay total treatment costs upfront. Emergency care is provided first with payment afterward, but providers may refuse non-urgent treatment without insurance. Most Japanese visas require proof of health insurance before travel, making comprehensive coverage essential for entry.

Public Health Insurance Coverage in Japan

Japan's statutory health insurance covered 98.3% of the population as of 2020, divided into three schemes:

• Employment-based health insurance (被用者保険): Covers full-time employees of private companies, public agencies, and non-profit organizations (58.6% of population)
• National health insurance (国民健康保険): For residents under 75 who aren't full-time employees (27% of population)
• Health insurance for senior citizens (後期高齢者医療制度): All residents aged 75 and above (12.7% of population)

These schemes cover at least 70% of most public healthcare costs, with patients responsible for remaining expenses not covered by public insurance.

What Does Japanese Public Healthcare Cover?

While health insurance covers at least 70% of healthcare costs for most people, coverage increases to 80-90% for children, older people, low-income adults, and those with disabilities or chronic conditions.

Covered services include:

• Primary care physician and specialist treatment visits
• Hospital visits and emergency treatment
• Selected mental healthcare treatment
• Prescription drugs and physical therapy
• Most dental care and some eye-care
• Preventative screenings and health education
• Doctor-prescribed alternative treatments like acupuncture (鍼)
• Home care services from medical institutions
• Palliative hospice care (ホスピス・緩和ケア)

Not covered by public insurance:

• Cosmetic and elective surgery
• Specialist treatment without GP approval
• Sexual healthcare (contraception, abortion, fertility treatments)
• Non-scheduled vaccinations
• Eyeglasses or contact lenses (except children under 9)
• Optometry services from non-physicians

How to Apply for Public Health Insurance in Japan

Companies in Japan arrange employment-based health insurance (EHI) automatically. For national health insurance (NHI) or senior coverage, you must apply within two weeks of arriving in Japan.

Required documents for application:

• Passport with Japanese visa or residence card
• Japanese address details
• Social security number (個人番号/マイナンバー) or tax ID equivalent
• Proof of income (determines insurance payments)

Visit your local municipal office to apply. One household member can apply for all covered individuals. You'll receive a health insurance card (健康保険証) to present at medical appointments as proof of coverage.

Private Health Insurance in Japan

Over 70% of Japan's population holds private health insurance, typically as a supplement to state healthcare for complete coverage. Private insurance provides access to treatments unavailable through public schemes, including expanded mental healthcare services.

Advantages of Private Health Insurance

• Copayment coverage: Covers the 10-30% costs you pay under public healthcare
• Full healthcare access: Freedom to use public or private services across Japan
• English-speaking services: Access to English-speaking providers privately
• Wider treatment range: Access to mental healthcare, dental care, and alternative treatments not available publicly
• Shorter waiting times: Even faster treatment through private providers

Monthly expenses increase as you pay both statutory and private premiums. Fees are risk-based, meaning higher premiums for retirees or those with existing medical conditions.

How Private Health Insurance Works

The Financial Services Agency (FSA, 金融庁) regulates all legitimate insurers in Japan. Each provider has its own registration process, policies (basic, premium), and associated costs.

Your costs depend on:

• Policy choice and claim limit (e.g., ¥100 million)
• Coverage location (whether usable outside Japan)
• Risk factors (age, lifestyle, health status)
• Number of covered people (family packages available)

Typically, you settle medical bills upfront and claim reimbursement from your insurer. Some companies pay large bills directly with necessary information provided.

International Health Insurance Options

International health insurance companies offering coverage in Japan include:

• Allianz Care
• Cigna Global

Japanese Insurance Costs and Reimbursements

EHI contributions average around 10% of salary and bonuses, split between workers and employers. Workers individually contribute about 5% of gross income toward health insurance. For example, earning ¥350,000 monthly means approximately ¥17,500 in monthly health insurance premiums.

Complete private health insurance plans typically cost ¥25,000-65,000 monthly in Japan. NHI and senior insurance payments are based on age, income, regional location, and household size. Long-term care insurance payments generally work out to around 2% of salary. Japanese health insurance contributions and copayments are both tax deductible.

Current monthly copayment limits for under-70s:

• ¥150,000 for high earners
• ¥80,100 for the general population
• ¥35,400 for low earners

For ongoing medical care lasting over three months, caps are lower from the fourth month onwards.

Health Insurance for Unemployed or Low Earners

Japan's public assistance system (生活保護制度) helps those unable to pay for healthcare, education, rent, and other living expenses. This includes low-earning pensioners, those with health problems or disabilities, and households with incomes below specific thresholds.

Low earners, pensioners, and young children pay discounted copayment rates for public healthcare. Pensioners over 75 pay 10%, while preschool children and those aged 70-74 pay 20%.
