Two Types of Insurance
Japan has a universal healthcare system. Which plan you join depends on your employment status.
| Feature | National Health Insurance (NHI) | Employee Health Insurance (Shakai Hoken) |
|---|---|---|
| Who joins | Self-employed, freelancers, students, unemployed | Company employees (30+ hrs/week) |
| Enrollment | Ward office (you enroll yourself) | Employer enrolls you automatically |
| Coverage | 70% of medical costs | 70% of medical costs |
| Premium | Based on previous year's income | ~10% of salary (split 50/50 with employer) |
| Dependents | Each person pays separately | Dependents covered at no extra cost |
| Extras | Basic coverage only | Includes pension, injury/illness leave benefits |
Important: Insurance is Mandatory
All residents staying in Japan for 3 months or more must enroll in health insurance. If you don't enroll through your employer, you must sign up for NHI at your ward office within 14 days of moving in. Failure to enroll can result in backdated premiums for up to 2 years.
NHI Enrollment Process
If you're self-employed, freelancing, or between jobs, follow these steps to enroll in National Health Insurance.
Register Address
Complete your address registration (juminhyo) at your ward office. This is a prerequisite for NHI enrollment.
Visit Insurance Counter
Go to the NHI counter at your ward office. Bring your residence card, passport, and My Number notification.
Fill Out Application
Complete the NHI application form. Staff can help with Japanese. Some wards have English forms available.
Receive Your Card
Your insurance card arrives by mail in 1-2 weeks. You can use the temporary receipt for medical visits in the meantime.
How Much Does It Cost?
NHI premiums vary by ward and income. Here are typical examples for Tokyo residents.
Example: Annual Income ¥3,000,000
Example: Annual Income ¥5,000,000
High-Cost Medical Expense Benefit
Japan's healthcare system includes a safety net: if your out-of-pocket medical expenses exceed a certain threshold in one month (typically ¥80,100 for standard income earners), the excess is reimbursed. This means even major surgery or hospitalization won't bankrupt you.
- Apply for a Gendo-gaku Tekiyo Nintei-sho (Limit Certificate) in advance for automatic application
- Without the certificate, pay upfront and apply for reimbursement within 2 years
- Monthly cap adjusts based on income level — lower income means lower cap
What's Covered?
Japanese health insurance covers most medical services. Here's a breakdown.

Leaving Japan? Don't Forget to Disenroll
If you leave Japan permanently, visit your ward office to cancel your NHI before departing. You may be eligible for a partial premium refund for months already paid. Failing to cancel can result in continued charges and complications if you return to Japan in the future.
