Moving to Japan as an international student is exciting, but understanding the Japanese healthcare system can feel confusing at first. One of the most important things you need to prepare after arriving in Japan is health insurance.
Fortunately, 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.
This guide explains everything international students need to know about health insurance in Japan, including:
- Whether health insurance is mandatory
- How the Japanese National Health Insurance system works
- Monthly insurance costs
- How much medical treatment actually costs
- Private insurance options
- Emergency medical support
- Common mistakes international students make
Is Health Insurance Mandatory for International Students in Japan?
Yes.
In most cases, international students staying in Japan for more than 3 months are legally required to enroll in Japan’s National Health Insurance system (NHI), known in Japanese as Kokumin Kenko Hoken (国民健康保険).
This rule applies to:
- University students
- Language school students
- Vocational school students
- Exchange students
- Research students
Once you complete your residence registration at your local city office, you are generally expected to enroll in National Health Insurance.
What Is Japan’s National Health Insurance?
Japan’s National Health Insurance system is a public healthcare program that helps residents pay medical expenses.
When you are enrolled, the insurance typically covers:
- Doctor visits
- Hospital treatment
- Surgery
- Prescription medication
- Emergency treatment
- Some dental procedures
In most cases, the insurance pays 70% of eligible medical expenses, while you pay the remaining 30%.
For example:
| Medical Bill | Amount You Pay |
|---|---|
| ¥3,000 | About ¥900 |
| ¥10,000 | About ¥3,000 |
| ¥50,000 | About ¥15,000 |
This makes healthcare in Japan far more affordable compared to countries without universal healthcare systems.
How Much Does National Health Insurance Cost for Students?
The monthly insurance premium for students is usually relatively low because most students have limited income.
Typical student premiums range from:
- ¥1,500 to ¥3,000 per month
However, the exact amount depends on:
- Your city or ward
- Your previous year’s income
- Scholarship status
- Part-time work income
Newly arrived students often pay lower premiums during their first year in Japan.

Although National Health Insurance is excellent, some students also purchase private insurance for additional protection.
Private insurance may help cover:

What About Travel Insurance?
Travel insurance is useful during your initial move to Japan, but it is usually not enough for long-term students.
Many travel insurance plans:
- Expire after several months
- Have coverage limits
- Do not fully satisfy Japanese residency expectations
Long-term students should still enroll in National Health Insurance.
Mental Health Support in Japan
Mental health awareness has improved significantly in Japan in recent years.
International students can often access:

National Health Insurance generally covers part of psychiatric and mental health treatment costs.
However, availability of English-speaking specialists may vary depending on the region.
Emergency Medical Services in Japan
Japan has reliable emergency medical services.
Emergency Numbers
| Service | Number |
|---|---|
| Ambulance / Fire | 119 |
| Police | 110 |
Ambulance services in Japan are generally free.
However, hospital treatment itself is not free, which is another reason insurance is essential.
Tips for International Students Using Japanese Healthcare
Carry Your Insurance Information
Always keep your insurance card or My Number-linked insurance information available.
Without proof of insurance, you may need to pay the full amount temporarily.
Visit Clinics Instead of Large Hospitals First
Japan often encourages patients to visit local clinics before going to major hospitals.
Large hospitals may charge additional fees without a referral.
Pharmacies Are Separate
After seeing a doctor, you often receive a prescription that must be filled at a separate pharmacy.
This is normal in Japan.
Learn Basic Medical Japanese
Helpful phrases include:
| English | Japanese |
|---|---|
| I have a fever | Netsu ga arimasu |
| My stomach hurts | Onaka ga itai desu |
| I need a doctor | Isha ga hitsuyo desu |
