You just moved to Tokyo for your dream job. You’re excited about the adventure ahead, until someone mentions you need to sort out health insurance within 14 days of arrival. Suddenly, you’re drowning in Japanese paperwork, wondering if you’ll be fined for missing a deadline you didn’t even know existed.
Japan offers high-quality, affordable medical care, but understanding how the system works is key to avoiding costly surprises. The good news? As a resident, you’re typically covered under Japan’s public health system.
However, even with Japan’s mandatory health insurance, you’re paying 30% of every medical bill. That seemingly affordable doctor’s visit? You’re still paying out ¥2,000-3,000 each time. Those prescription medications? Another 30% from your wallet. And if you need an English-speaking doctor? Good luck finding one that accepts national insurance as most charge premium rates without one.
You might still want to consider private health insurance in Japan or at least hybrid plans, especially if you’re looking for services in English, more flexibility, or short-term solutions as a new arrival. In this article, we’ll review the best health insurance options for expats in Japan. We’ll compare costs, coverage, and which gaps each one fills so you can choose the right plan based on your specific needs whether you’re here short-term, starting a family, or need coverage that works both in Japan and back home.
1. National Health Insurance (NHI) – 国民健康保険
National Health Insurance is Japan’s safety net for residents who aren’t covered by employer insurance. This includes freelancers, students, unemployed individuals, retirees under 75, and anyone working less than 30 hours per week. If you fall into any of these categories, NHI enrollment isn’t optional, it’s legally required within 14 days of arriving in Japan or leaving your employer’s insurance plan.
The enrollment process happens at your local city or ward office (市役所 or 区役所). You’ll need to bring your residence card, passport, and if you’re switching from employer insurance, a certificate proving your previous coverage ended. If you miss that 14-day deadline, you’ll owe premiums backdated to when you became eligible plus you’ll pay full price for any medical care during that gap.
NHI covers 70% of most medical expenses, leaving you to pay the remaining 30% out of pocket. This includes doctor visits, hospital stays, surgeries, prescription medications, and basic dental care. Mental health services and preventive care have limited coverage. Cosmetic procedures, health checkups, orthodontics, and normal childbirth aren’t covered at all.
Your premium calculation is complex and varies by municipality. It’s based on three components: medical insurance, elderly support fund, and long-term care insurance (for those 40-64). Each component includes both an income-based portion and a flat per-capita charge.
If you’ve just arrived in Japan, you typically pay minimal premiums your first year, often around ¥2,000 per month for students or low-income earners because you had no Japanese income the previous year. Premiums are also household-based. If you’re married, both incomes count toward calculation even if only one spouse works.
You must file a tax return every year, even with no income, or you’ll be charged the maximum premium rate. If you leave Japan without properly canceling NHI, premiums continue accumulating, creating problems if you return.
Benefits:
- Covers 70% of medical costs (you pay 30%)
- Includes hospitalization, outpatient care, surgeries, and prescriptions
- Basic dental treatments covered
- Emergency care included
- Ambulance services free
- High-cost medical expense cap limits monthly out-of-pocket costs to around ¥80,100 for average earners
- Valid at any hospital or clinic in Japan
- Children receive additional subsidies in many municipalities
Not Covered:
- Cosmetic procedures
- Regular health checkups
- Orthodontics
- Normal pregnancy and childbirth (though complications are covered)
- Private hospital rooms
- Most mental health services beyond basic treatment
Typical monthly cost:
Around ¥15,000–¥20,000 ($135–$180 USD) if you’re mid-income; lower if you’re a student or unemployed.
Here’s the Employee Health Insurance (EHI) section in the same detailed style:
2. Employee Health Insurance (EHI) – 健康保険
Employee Health Insurance is mandatory for anyone working 30 or more hours per week at a Japanese company. Your employer handles enrollment automatically. They’re legally required to register you within five days of hiring. Unlike NHI, you don’t need to visit any government office or fill out applications yourself.
The cost structure is straightforward: your employer pays exactly half of your premium, and the other half is deducted from your monthly salary. In Tokyo, this typically equals about 9.98% of your monthly salary, meaning you pay roughly 5% while your employer covers the rest.
One significant advantage over NHI is that EHI premiums are individually based, not household-based. Your spouse’s income doesn’t affect your rate, and you can add unemployed dependents (spouse and children) to your coverage at no additional cost, which is a major benefit for families.
Benefits:
- Covers 70% of medical costs (you pay 30%)
- Includes all services covered by NHI plus potentially more
- Free coverage for unemployed dependents
- Injury and illness leave compensation (usually 60-80% of salary)
- Often includes enhanced maternity benefits
- Some plans offer annual health checkups
- Premium automatically adjusted if salary changes
- No need to file tax returns for premium calculation
Additional Perks (varies by company):
- Comprehensive annual health screenings
- Dental and vision benefits
- Mental health support programs
- Gym membership subsidies
- Enhanced maternity/paternity leave payments
- Access to company-affiliated hospitals with reduced fees
Important Notes:
- Coverage continues for 20 days after leaving your job
- You can extend coverage for up to 2 years through voluntary continuation (任意継続) at double the premium
- Part-time workers under 30 hours/week aren’t eligible
- Premium caps at around ¥68,000/month even for high earners
Here’s the Private & International Insurance section in the same detailed style:
3. Private & International Health Insurance
Private health insurance serves two distinct groups in Japan: short-term visitors staying less than 90 days who can’t access public insurance, and long-term residents who want coverage beyond what NHI or EHI provides. While not legally required if you have public insurance, many expats find private coverage essential for filling expensive gaps.
The primary advantage is comprehensive coverage without the 30% copayment. Where NHI leaves you paying ¥30,000 for a ¥100,000 procedure, quality private insurance covers the full amount. More importantly, private plans typically include services that public insurance ignores entirely: comprehensive dental work, vision care, mental health support, and full maternity coverage including normal childbirth.
For expats, the real value often lies in English-language support and global coverage. Need to see an English-speaking specialist at an international clinic? Private insurance covers those premium rates. Planning trips home or elsewhere in Asia? Your coverage travels with you. Some plans even offer direct billing at select hospitals, eliminating the need to pay upfront and wait for reimbursement.
Benefits:
- 100% coverage available (no copayments)
- English-speaking customer service and claims support
- Coverage at international clinics and private hospitals
- Global coverage for travel and home visits
- Direct billing at participating facilities
- Comprehensive dental, vision, and mental health benefits
- Full maternity coverage including normal delivery
- Private hospital rooms
- Medical evacuation and repatriation
- Pre-existing condition coverage (varies by provider)
- Health screening and preventive care
- No need to file Japanese tax returns
Drawbacks:
- Monthly premiums range from ¥15,000-¥50,000 ($150-$500)
- Most Japanese hospitals require upfront payment (you claim later)
- Some providers exclude pre-existing conditions
- Coverage limits and deductibles vary widely
- Not accepted at all Japanese medical facilities

Conclusion
Whether you’re settling in for a few years or just testing the waters of what Japan has to offer, having proper health insurance in Japan is not just a legal requirement—it’s peace of mind.
At the very least, enrolling in either National Health Insurance (NHI) or Employee Health Insurance (EHI) ensures you’re covered for most medical needs. And if you are an expat who wants more flexibility or need specific beneifts (i.e. English-speaking doctors, private hospital rooms, or global coverage) pairing this with a private plan can offer the best of both worlds.
Japan’s public health system is reliable, affordable, and accessible to most long-term residents. But depending on your lifestyle, family needs, or expectations for comfortable living, a private or international insurance may be worth considering.
Ultimately, the key takeaway is – Health insurance in Japan is straightforward, but not one-size-fits-all. Take time to evaluate what matters most to you. Whether it’s budget, access, or specific services, you should choose a plan that matches your life in Japan.
