If you’ve confirmed that you need to enroll in National Health Insurance during your working holiday in Japan (see our guide on health insurance requirements for working holiday visa holders if you haven’t yet), the next question is simple: how do you actually do it? This guide walks through the enrollment process step by step, with a few notes specific to working holiday makers along the way.
Before You Start: What You’ll Need
- Your residence card (Zairyu Card)
- Your passport
- Proof of your registered address (this is usually completed in the same visit, as part of residence registration)
Unlike international students, you generally won’t need a certificate of enrollment from a school — but if you’re working through a program or agency that assisted with your visa, it’s worth checking whether they have any specific documentation requirements for you.
Step 1: Complete Residence Registration First
Before enrolling in NHI, you need to register your address at the municipal office (ward or city office) covering the area where you’re living. This is expected within 14 days of moving into your residence, and it’s the same process any new resident goes through, regardless of visa type.
If you know you’ll be moving between cities during your working holiday (common if you’re doing seasonal work or traveling between jobs), keep in mind you’ll need to repeat this registration step each time you establish a new address — more on that below.
Step 2: Enroll in NHI at the Same Office
Most municipal offices handle NHI enrollment at the same visit as residence registration, often at a neighboring counter. Staff will typically guide you through a short enrollment form asking for basic information — your name, address, and residence card details.
Step 3: Receive Your Insurance Card
Your NHI card is usually mailed to your registered address within one to two weeks, though this varies by municipality. If you need medical care before it arrives, ask the counter staff about a temporary certificate — many offices can issue one on request.
What’s Different for Working Holiday Makers Specifically
If you move cities during your stay
Each time you relocate — say, from a job in Tokyo to seasonal farm work in Hokkaido — you’re expected to update your residence registration, which also means re-registering (or updating) your NHI enrollment at the new municipal office. Premiums are calculated at the municipal level, so this isn’t just a formality; it can affect what you’re billed.
If your income is irregular or seasonal
NHI premiums are based on income, and working holiday income often varies month to month. If your income is genuinely low, ask about premium reduction applications when you enroll — this isn’t automatic, and it’s worth asking about directly rather than assuming you don’t qualify.
If you take on full-time employment partway through your stay
Some working holiday makers end up in more structured full-time roles. If this happens to you, your employer may be required to enroll you in Employees’ Health Insurance (Shakai Hoken) instead of NHI. Ask your employer directly if this applies to your situation — you generally shouldn’t be enrolled in both at once.
What to Do Before You Leave Japan
If you’re departing before your visa period ends, formally deregister from NHI at your municipal office before you go. Skipping this step can leave your enrollment technically active, which may lead to billing complications after you’ve already left the country.
Frequently Asked Questions
Do I need to enroll if I’m only staying a few months? The three-month threshold is what matters, not your total visa validity. If you register a residence and stay past three months, enrollment is expected — even if your original plan was for a shorter stay.
What if I haven’t decided how long I’ll stay in one city? Enroll based on where you’re actually living now. If your plans change and you relocate, update your registration at that point — there’s no need to guess in advance.
Can I enroll before I have a fixed address? No — NHI enrollment is tied to your residence registration, which requires a fixed address. If you’re still figuring out longer-term housing, enrollment happens once you’ve settled somewhere and registered.
What happens if I skip enrollment entirely during my working holiday? You’d be uninsured for medical care, meaning full out-of-pocket costs if you need treatment, and potentially retroactive premium billing if your municipal office later determines you should have been enrolled.
