Required Documents for National Health Insurance Enrollment
To join Japan's National Health Insurance (NHI) system, you'll need to prepare a few key documents. While the requirements are generally consistent across municipalities, some local offices might ask for extra paperwork based on your circumstances. Below are the three main documents you'll need for enrollment.
Passport
Your valid passport is essential for confirming your identity and legal entry into Japan. It must remain valid for the duration of your stay. During the enrollment process, municipal staff will check your identity and visa details, making photocopies of important pages such as those showing your personal information, entry stamps, and any visa extensions.
If your passport is close to expiring, it’s a good idea to renew it beforehand to avoid any issues.
Residence Card (Zairyu Card)
The Residence Card (Zairyu Card) is another crucial document. It verifies your legal residency, visa status, and the length of your authorized stay in Japan.
You’ll need to present the original card along with your passport. The municipal office will make copies for their records. Be sure your Residence Card is valid, as an expired card will prevent you from completing your enrollment.
For those holding specific visa types - such as Entertainer, Technical Intern Training, Dependent, Designated Activity, or Official - additional documents may be required. These might include proof of your activities in Japan and confirmation that your stay will exceed three months. This is especially important for residents not yet registered in the basic Resident Registration system.
Application Form
The final step involves completing an application form, which you’ll receive at your local municipal office. This form asks for basic details like your name, address, contact information, visa status, and intended length of stay. Don’t worry if you’re unsure about any sections - staff members are on hand to guide you through the process and ensure everything is filled out correctly.
Extra Documents for Special Situations
While the three main documents are sufficient for most enrollment cases, there are situations where additional paperwork is required. These extra documents help ensure that all enrollment details are accurate and complete.
For Heads of Household
If you're the head of your household, make sure to bring your current NHI card. This allows municipal staff to verify your previous coverage details, making the enrollment process smoother and quicker.
When Moving Between Cities
If you're relocating to a new municipality, there are two important steps to complete within 14 days of your move. First, file a moving-out notification at your current city office. Then, submit a moving-in notification at the office in your new city or town. Be sure to bring your NHI card or Certificate of Eligibility when you visit the new office.
Since requirements can vary depending on the municipality, it's a good idea to contact your new local office ahead of time to confirm exactly what documents are needed. If you’re moving within the same city or ward, the process is simpler - you only need to report your address change instead of withdrawing and re-enrolling.
For Non-Residents or Special Cases
Non-residents or individuals with specific visa types may need to provide a certificate of activity or similar documentation that outlines their activities in Japan. The exact requirements depend on your visa category and personal situation.
For those living in Fujimi, Fujimino, or Miyoshi, enrollment requirements can differ considerably. In such cases, it's best to consult the Insurance-Pension Sections in these areas for detailed advice on the additional documents you might need.

Many foreign residents complete their NHI enrollment on the same day they register their address, making it a seamless step in settling into Japan's healthcare system.
Visit Your Local City or Ward Office
Head to your local city hall or ward office during business hours. Let the receptionist know that you wish to enroll in National Health Insurance. They'll guide you to the appropriate section, often referred to as the NHI Section or Residents Office.

Submit the Required Documents
Hand over your passport and valid Residence Card. If requested, provide your My Number card or Notification card as well. Depending on your local office, additional documents may be required, so be sure to bring anything they've asked for in advance. Having your personal seal (Inkan) with you can also be useful.
You'll need to fill out some forms with your personal information. If you're unsure about anything, don't hesitate to ask for assistance - the staff are there to help.
Receive Your Insurance Card
Once your enrollment is complete, you can expect to receive your insurance card within 2–3 weeks after submitting your documents and making the initial payment .
Starting from 2nd December 2024, only My Number Health Insurance Cards will be issued. If you already have an insurance card issued before this date, it will remain valid for up to one year .
Typically, data registration is finalized within five days after your Notification of Eligibility is submitted to the Health Insurance Association. However, the arrival of your physical card or digital access may take a little longer. Once you've received your card, it serves as confirmation of your successful enrollment in the NHI system.
Tips for Foreign Residents
Once you've gathered your documents and completed your enrollment, here are some practical suggestions to help you navigate Japan's healthcare system more smoothly.
Enroll Quickly to Avoid Coverage Gaps
Make sure to register for National Health Insurance (NHI) as soon as possible. You need to enroll within 14 days of becoming eligible to avoid retroactive premium payments and to comply with legal requirements. If you delay, you could be responsible for unpaid premiums going back up to two years. Foreign residents staying in Japan for more than three months are generally required to enroll in NHI.
Head to your local municipal office (open 9:00–17:00, Monday to Friday) right after completing your resident registration. Since premiums are calculated starting from the month you enroll, registering early not only prevents unexpected medical expenses but also ensures you're following the law.
Along with timely enrollment, having access to language support is essential for a better healthcare experience in Japan.
Find English Support Resources
Language barriers can make accessing medical care challenging, so it's a good idea to familiarize yourself with available multilingual resources. Research clinics and hospitals in your area that provide English-speaking services before you actually need them. This preparation can save you a lot of stress in emergencies.
One helpful resource is Myjin (https://myjin.jp), which offers a curated list of healthcare providers in Japan that cater to international patients. The directory includes general clinics, gynecologists, dentists, and dermatologists, all with verified contact information and English support.
The AMDA International Medical Information Center is another excellent option. They provide general guidance on Japan's medical system, help with completing medical forms, and assist in locating facilities with staff who speak foreign languages. They also offer telephone consultation and interpretation services in multiple languages.
For additional support, consider downloading apps like Dr. Passport, which lets you store your medical history, describe symptoms, and communicate medical needs in up to 12 languages. These tools are especially helpful when you're navigating a new healthcare system.
Always carry your health insurance card and identification with you. Don’t hesitate to ask questions to ensure you fully understand your diagnosis and treatment options. Familiarize yourself with what your health insurance covers, including co-pays, hospital stays, and specialist consultations, so you can make well-informed choices about your healthcare in Japan.

Enrolling in Japan's National Health Insurance (NHI) system requires proper preparation and timely action. Having the right documents in hand can simplify the process and save you from unnecessary headaches.
