Introduction
Whether you’re moving to Japan for work, love, family, or a long-term lifestyle shift, the first 90 days can feel like a whirlwind. Japan is efficient, organized, and deeply safe — but its administrative systems, cultural rhythms, and hidden “unwritten rules” can be overwhelming to newcomers.
As someone who helps individuals, families, and companies navigate this process every day via my company, Nippon Bridge, I can say this confidently:
Your first 90 days in Japan will shape your entire long-term experience.
In this edition, I’ll walk you through a clear, practical, step-by-step roadmap for your first three months — the version I give to clients when they land and need everything laid out simply and correctly.
One important note before we begin: 2026 is a year of meaningful administrative reform in Japan. Several new systems are launching or taking effect this year that directly affect foreign residents. I’ve flagged each one throughout this guide so you’re not caught off guard.
Let’s get you settled.
1. Your First 7 Days: Foundations & Registration
These first steps are essential. Skip them or delay them, and everything else becomes harder.
✔ 1. Register Your Address at City Hall (必須 / Mandatory)
Within 14 days of moving into your residence, you must submit a “moving-in” notification at your local city hall. Failure to do so can result in fines of up to ¥200,000 and complications with banking, insurance, and future visa applications.
You’ll receive:
- Residence card update
- Your My Number (if new) or reactivation
- Access to healthcare, pension, and other systems
Important 2026 update: Starting June 14, 2026, Japan is launching the Tokutei Zairyū Card (特定在留カード) — a new integrated card that combines your Residence Card and My Number Card into a single document. It is not mandatory; you can continue using your separate cards if you prefer. But if you’re arriving after June 2026, it’s worth applying for the combined card at your next visit to an Immigration Bureau, as it significantly reduces the administrative back-and-forth in daily life.
Also worth noting: Japan is now actively cross-checking whether your registered address matches your actual residence as part of stricter compliance screening. Make sure your address on your residence card always reflects where you actually live.
Tip: City halls can be intimidating. Go early, bring your passport, residence card, lease agreement, and a pen. If you’re with a company, HR may assist — but always double-check the details yourself.
✔ 2. Enroll in the Correct Health Insurance & Pension System
Japan has two major public systems you must join depending on your work situation:
If You Are Employed Full-Time by a Japanese Company:
Your employer is required to enroll you in:
- Employees’ Health Insurance（健康保険 / 社会保険）
- Employees’ Pension（厚生年金）
You do not join National Health Insurance (国民健康保険). You also do not enroll yourself — the company handles all paperwork.
If You Are Self-Employed, Freelancing, Between Jobs, or a Student:
You must join:
- National Health Insurance（国民健康保険）
- National Pension（国民年金）
You enroll at your local city hall after moving in.
Why It Matters — and Why It Matters Even More in 2026:
- Medical costs without health insurance are extremely high.
- Pension enrollment is legally mandatory for all residents.
- Later, when leaving Japan permanently, you can claim a partial pension refund (脱退一時金).
Critical 2026/2027 update: The Japanese government has announced that from June 2027, foreign residents who fail to pay their National Health Insurance premiums or pension contributions will, in principle, be denied visa renewals or status changes. The compliance rate among foreign residents has been low — around 50% for pension and 63% for health insurance — and the government is now closing that gap with enforcement. This is not yet in force, but it will be before your first renewal likely comes around. Set up automatic payment from day one.
A related 2026 change: Traditional plastic health insurance cards are no longer being issued and were in their final grace period until March 31, 2026. From now on, your My Number Card registered for health insurance (Myna Hokensho) is your primary means of accessing medical care. Make sure your My Number Card is registered for health insurance at your city hall or via the government app.
✔ 3. Open a Bank Account
This can be surprisingly tricky for newcomers. Most standard Japanese bank accounts require you to have lived in Japan for at least six months — though some banks offer limited “basic” accounts to new arrivals.
The top foreigner-friendly options in 2026 (policies can shift, so confirm directly before visiting):
SMBC Prestia
- Most English-friendly major bank
- English app, phone support, documents
- International-card friendly
- Still the smoothest full-service option for mid-term residents
- Requires My Number Card and proof of address
Japan Post Bank (ゆうちょ銀行)
- Easiest for new arrivals — accessible in every post office nationwide
- More forgiving on residency history than most banks
- No English interface, but simple procedures
- Good as a “starter” bank before upgrading later
SBI Shinsei Bank
- Increasingly popular among foreign residents
- Strong English-language support online
- Good for those who arrive without a long Japan residency history
- Fully digital onboarding available
Rakuten Bank (digital)
- No English interface, but very easy onboarding
- Good app, simple transfers
- Works well for freelancers or remote workers
- Requires My Number Card, Japanese phone number, and address
Wise Account + Debit (not a Japanese bank account, but useful)
- Excellent for receiving overseas funds
- Multi-currency
- Cannot be used for salary from most Japanese companies
- Works well in combination with a Japanese bank account
Important 2026 note: Digital banks (Rakuten, Sony Bank, PayPay Bank) now require your My Number Card with its IC chip for identity verification during onboarding — a passport alone is no longer sufficient for app-based applications. Get your My Number Card sorted at city hall before attempting to open a digital account.
Why immediately? You’ll need it for salary, rent, utilities, mobile plans, and online purchases.
✔ 4. Get a Local SIM / Phone Number
A Japanese phone number unlocks everything: deliveries, bank and other apps, apartment access forms, school registrations, and more.
The most reliable foreigner-friendly options in 2026:
- GTN Mobile — Multilingual support (13 languages), convenience store payment (no credit card required), fast sign-up. Top choice for new arrivals who want help.
- Mobal — No Residence Card required; can be ordered before arrival with just a passport. Great for Day 1.
- Sakura Mobile — Well-reviewed, English support, runs on NTT Docomo (Japan’s most reliable network), flexible plans.
- Rakuten Mobile — Cheap, but requires a Residence Card and Japanese payment method at sign-up.
- LINEMO / povo — Budget-friendly long-term options, but expect a Japanese-only setup process.
✔ 5. Set Up Your Utilities (If Not Already Done)
You may need to turn on:
- Electricity
- Gas (requires in-person appointment)
- Water
- Internet (often 2–3 weeks for installation)
If you’re renting long-term, your property manager may help. If you’re alone — prepare to call the utility companies (or ask for assistance if your Japanese is limited).
2. Days 8–30: Daily Life Infrastructure
Once your basics are set up, the next step is making your life actually functional.
✔ 1. Confirm National Pension Enrollment
Mandatory for all residents, even if you’re temporarily in Japan. As noted above — payment compliance now has direct consequences for your visa status from 2027 onward. Set up a direct debit payment plan early. If finances are tight, you can apply for a payment reduction or exemption at city hall — this is far better than simply not paying.
✔ 2. Download Critical Apps
Japan uses specific apps that make life infinitely easier:
- LINE: 99% of communication in Japan
- PayPay: Dominant mobile payment app
- Google Maps + Japan Transit Apps: Train navigation is an art
- Local ward/city apps: Trash schedules, emergencies, alerts
- Delivery apps: UberEats, Demae-can
- Mercari: Japan’s #1 second-hand online marketplace
- MyNa Portal (マイナポータル): The government’s official app — increasingly essential for health insurance verification, tax filings, and benefit confirmations
✔ 3. Understand Trash Rules (Seriously!)
Japan takes waste separation extremely seriously — every city has a different system. Getting it wrong frustrates neighbors and can invite warnings. Download your city’s waste calendar and follow the icons.
✔ 4. Build Language Survival Skills
You don’t need fluency to thrive here, but learning these helps:
- How to say your address
- How to read train lines
- How to explain food allergies and other dietary restrictions
- Polite forms for shopping, service interactions, etc.
Even learning hiragana + katakana (the basic, phonetic alphabets used in Japan) unlocks a huge amount of daily life.
✔ 5. Establish Even a Simple Social Base
Japan can feel isolating in the first month. Try:
- Language exchange groups
- Fitness communities
- International centers
- University cafes
- Meetup or Facebook groups in your city
Making even one local connection changes everything.
3. Days 31–60: Stability & Comfort
Around the second month, Japan begins to feel familiar. This is when you should focus on deeper integration.
✔ 1. Choose a Long-Term Healthcare Provider
If you plan to stay long-term, find:
- A regular clinic
- A dentist
- (If needed) a mental health provider
English-speaking options exist in most major cities. When visiting clinics, present your My Number Card registered as your health insurance card — this is the standard method as of 2026.
✔ 2. Understand Your Taxes
Important distinctions:
- Resident taxes are charged the year after you earn money
- Insurance, pension, and city taxes have separate bills
- Your employer may or may not calculate everything for you
2026 update: The income tax basic deduction has increased from ¥480,000 to ¥580,000, and withholding rates have been reduced for salaries under approximately ¥25.5 million from January 2026. The government is also heavily promoting e-Tax (online tax filing), which now requires your My Number Card for digital identity verification — another reason to get that card as early as possible.
If you’re freelancing or running a business: Hire a Japanese tax accountant early.
✔ 3. Explore Regional Travel
Japan’s inner regions offer an escape from the intensity of the big cities. Some excellent 1–2 day trips:
- Kyushu hot spring towns
- Hakone
- Nikko
- Kanazawa
- Matsumoto
- Hokkaido’s countryside
Traveling deepens your understanding of the culture far more than staying within major metropolitan centers.
✔ 4. Start Building Routines
Japan rewards consistency. Some recommended habits:
- Keep a running list of Japanese words you encounter
- Create a monthly expense calendar (Japan’s billing is staggered)
- Learn a new neighborhood each weekend
- Visit your local shotengai (shopping street) regularly
These routines help you feel at home quickly.
4. Days 61–90: Optimization & Long-Term Thinking
By month three, you should feel settled — and ready to strengthen your long-term foundation.
✔ 1. Reassess Your Visa & Future Plans
- Are you staying short-term or long-term?
- Do you need to renew soon?
- Are you considering Permanent Residency (PR)?
- Should you set up a company? (Business Manager, etc.)
Japan’s visa system rewards early planning — and the stakes have risen. As of 2026, immigration authorities are actively verifying that your registered address matches your actual residence, that your job duties align with your residence status, and that your tax and insurance payments are current. Any discrepancy can complicate renewals. Stay clean from the start.
✔ 2. Evaluate Your Housing Situation
After 60–90 days, ask yourself: Is the location right? Noise levels? Commute? Space? Cost?
If not perfect — it’s totally normal to move within your first year (although, if you’re on a two-year standard long-term lease, there may be 1–2 months of rent payable as a penalty for early termination).
✔ 3. Integrate into Local Culture
Japan becomes richer once you learn the deeper rhythms:
- Seasonal festivals
- Neighborhood meetings
- New Year traditions
- Osechi, hanami, obon, momiji (look those up!)
- Local etiquette nuances
Living in Japan is more than logistics — it’s rhythm, tradition, and everyday texture.
✔ 4. Build Your Long-Term Support Network
By now, make sure you have:
- A doctor
- A reliable English-speaking mechanic or electronics repair shop if needed
- A trusted administrative helper (friend, company, or consultant)
- A property agent if you’re planning to buy (Nippon Tradings International (NTI) will be happy to assist!)
- People you can call in emergencies
Your support network is your real safety net.
Final Thoughts
Your first 90 days in Japan will be filled with beauty, confusion, humor, bureaucracy, discovery, and occasional frustration — but if you follow the roadmap above, you’ll settle in smoothly and confidently.
2026 brings more administrative change than most years. The new Tokutei Zairyū Card, the end of traditional health insurance cards, the approaching enforcement of insurance payment compliance — these aren’t obstacles. They’re signs of a system maturing and, in many ways, becoming more transparent and streamlined for those who navigate it correctly.
Japan rewards patience, attentiveness, and curiosity. And once you understand the system, the country embraces you back.
Whether you’re here for a few years or a lifetime: Welcome home.
