Moving to Japan as an international student is exciting, but understanding the healthcare system can feel confusing at first. One of the most important things to sort out after arriving is health insurance. The good news: Japan has one of the best healthcare systems in the world, and most international students can access affordable medical treatment through the National Health Insurance system.

Is Health Insurance Mandatory for International Students?
Yes. International students staying in Japan for more than three months are legally required to enroll in National Health Insurance (NHI), known in Japanese as Kokumin Kenko Hoken. This applies to university students, language school students, vocational school students, exchange students, and research students alike.
Once you complete your residence registration at your local city office, you’re generally expected to enroll in NHI shortly after. For a full step-by-step walkthrough of this process, see: How to Enroll in National Health Insurance in Japan as an International Student
What Does National Health Insurance Cover?
NHI is a public healthcare program that helps residents pay medical expenses. Once enrolled, it typically covers doctor visits, hospital treatment, surgery, prescription medication, emergency treatment, and some dental procedures. In most cases, insurance pays 70% of eligible medical costs, and you pay the remaining 30%.
| Medical Bill | Amount You Pay (30%) |
|---|---|
| ¥3,000 | About ¥900 |
| ¥10,000 | About ¥3,000 |
| ¥50,000 | About ¥15,000 |
This makes healthcare in Japan far more affordable than in countries without universal coverage.
How Much Does NHI Cost for Students?
Monthly premiums are usually relatively low for students, since most have limited income. As a general guide, student premiums often fall in the range of ¥2,000–¥15,000 per month, though the exact amount depends on your city or ward, your previous year’s income, scholarship status, and any part-time work income. Newly arrived students often pay on the lower end during their first year, and many municipalities offer additional reductions for low-income residents — worth asking about directly when you enroll.
What’s Usually Covered, and What Isn’t
Usually covered: general doctor consultations, hospital care, X-rays and tests, prescription medication, mental health treatment, surgery, emergency treatment, and some dental care.
Usually not covered: cosmetic surgery, preventive health checkups, most vaccinations, private hospital rooms, advanced elective treatments, and certain orthodontic procedures.
If you’re ever unsure whether something is covered, it’s worth confirming with the clinic or hospital before treatment.
Can International Students Use English-Speaking Hospitals?
Yes, particularly in larger cities. Popular student areas like Tokyo, Osaka, Kyoto, Yokohama, and Fukuoka tend to have clinics accustomed to treating international residents. Many universities also provide campus clinics, referral services, translation assistance, and emergency support information — worth checking with your international student office early on.
What Happens If You Don’t Enroll?
Failing to enroll can create real problems: large out-of-pocket medical bills, retroactive premium payments once your municipal office catches the gap, and potential complications with visa renewals or residency procedures.

Do International Students Need Private Insurance Too?
In some cases, yes. While NHI provides solid baseline coverage, some students add private insurance for extras like emergency evacuation, liability coverage, personal accident protection, or English-language support. Some universities also require students to join a supplementary university insurance plan alongside NHI.

What About Travel Insurance?
Travel insurance can be useful during your initial move, but it’s usually not a substitute for NHI if you’re staying long-term. Many travel insurance plans expire after a few months, carry lower coverage limits, and don’t satisfy Japan’s residency-based insurance requirements. If you’re staying to study, plan on enrolling in NHI regardless of any travel insurance you already have. Some students also ask whether proof of insurance is needed for the visa application itself — see: Is Health Insurance Required for a Japan Student Visa?
Mental Health Support in Japan
Mental health awareness has improved significantly in Japan in recent years. International students can generally access counseling services, psychiatry clinics, university mental health centers, and in some areas, English-speaking therapists. NHI generally covers part of psychiatric and mental health treatment costs, though availability of English-speaking specialists varies by region.
Emergency Medical Services
| Service | Number |
|---|---|
| Ambulance / Fire | 119 |
| Police | 110 |
Ambulance services in Japan are generally free, but the hospital treatment itself is not — another reason insurance matters even in an emergency.
Practical Tips for Using Japanese Healthcare
- Carry your insurance card or registration information at all times. Without it, you may need to pay the full cost upfront and seek reimbursement later.
- Visit local clinics before large hospitals when possible. Larger hospitals often charge additional fees for patients without a referral.
- Expect to visit a separate pharmacy after seeing a doctor. Prescriptions are typically filled at a pharmacy, not the clinic itself — this is standard practice in Japan.

What If Your Situation Changes After Graduation?
If you graduate and transition into full-time work in Japan, your insurance situation changes too — you’ll likely move from NHI to Employees’ Health Insurance through your new employer. See: Health Insurance When Switching from a Student Visa to a Work Visa in Japan
