Health insurance for immigrants in Japan

Understanding Japan's Health Insurance System

Japan requires all residents — including immigrants — to have health insurance. The system is mandatory and affordable, making it one of the world's most accessible healthcare options. Whether you're moving for work, study, or permanent residence, you'll need to understand how to enroll and use the system.

The Japanese government operates two main types of health insurance for residents:

• Employee health insurance — if you work for a company
• National health insurance — if you're self-employed, unemployed, or a student

Who Must Have Health Insurance?

You need to enroll if you:

• Have a valid residence permit in Japan
• Plan to stay longer than 3 months
• Work in Japan or are a dependent family member

Health insurance is not optional — it's legally required within a specific timeframe after you arrive and register as a resident.

Employee Health Insurance for Workers

If you're employed, your employer typically enrolls you automatically. This insurance covers you and eligible dependents. Here's what happens:

• Your employer pays roughly half the premium
• You pay the other half through monthly salary deductions
• Coverage includes doctor visits, hospital stays, prescription medications, and dental services
• Copayment rates are usually around 30% for most medical services

National Health Insurance for Self-Employed and Others

If you're not covered by an employer plan, you must enroll in the national health insurance system. This is managed locally:

• Registration happens at your municipal government office (ward or city office)
• Premiums are calculated based on your income and local area
• Monthly payments are typically affordable, especially for new residents
• Coverage is similar to employee insurance, with the same copayment structure

Getting Started: What You'll Need

When registering for health insurance, bring:

• Your residence card or passport
• Proof of address (rental contract, utility bill, or letter from employer)
• Your seal or signature
• Income documentation (if applying for national insurance)

Registration should happen within 14 days of receiving your residence permit. Delaying this process can result in penalties.

Using Your Health Insurance

Once enrolled, you'll receive a health insurance card. Show this at any hospital, clinic, or pharmacy in Japan. The card works at any medical facility — you're not limited to specific providers.

Emergency care is covered, and the system works seamlessly across Japan. Many doctors speak basic English in major cities, though having a translation app handy is helpful.

Confirming Your Details

Because insurance requirements and eligibility rules change periodically, always check the official website of your prefecture (state) or municipal government office before enrolling. They provide the most current information specific to your location.
