Moving to Japan: Everything You Need to Know

I moved to Japan without speaking a word of Japanese, without knowing anyone in the country, and with a visa situation that required three trips to the embassy before anyone could confirm it was actually valid. I'm telling you this not to brag about having survived bureaucratic chaos but to be honest about what moving to Japan is actually like versus the version of it that appears in expat content online. It is wonderful. It is also, at certain moments, the most administratively frustrating experience of your adult life.

Japan is a country that takes paperwork seriously in a way that is simultaneously impressive and exhausting. Everything requires a registered address, and you can't get a registered address without certain documents, and certain documents require a registered address — the circular dependencies stack up quickly in the first few weeks. I remember sitting in a ward office in my first month, not understanding what anyone was saying, watching a queue number tick up on a screen, and wondering if I'd made a terrible mistake. I hadn't. But nobody had told me to bring the right documents.

Several years later, I've navigated the visa renewals, the apartment hunting, the bank account applications, the health insurance enrollment, the pension system, the driving licence conversion, the tax filings, and the particular joy of explaining to a Japanese landlord that yes, a foreigner can be a reliable tenant. I know where the system works smoothly, where it doesn't, and what to actually do about it rather than what official guidance suggests.

This guide covers what you need to do before you move, in your first week, in your first month, and in your first year. It's not comprehensive — Japan's bureaucracy is too large for any single article to contain — but it covers the critical path and flags the moments where getting things wrong costs you time, money, or both.

Before You Move: Visa, Housing, and Pre-Departure Admin

The visa comes first, and everything else depends on it. Japan's main long-term visa categories for newcomers are the work visa (sponsored by a Japanese employer), the highly skilled professional visa (points-based, requires a job offer), the working holiday visa (available to citizens of around 30 countries, aged 18–30 or 35 depending on nationality), the spouse/dependent visa, and the startup visa available in certain municipalities. Each has specific requirements, processing times, and restrictions on what you can do once you arrive.

Before departure: sort your health insurance bridge, research where you'll live for at least the first month (short-term furnished apartments or monthly-rate guesthouses are far easier to arrange from overseas than standard rental apartments), and tell your home country bank you're moving so they don't freeze your card the first time you use it in Tokyo.

First Week: Registration, SIM Card, and the Ward Office

Within 14 days of arriving in Japan on a long-term visa, you're required to register at your local ward office (区役所, kuyakusho) to receive your Residence Card (在留カード, zairyu kaado) — if you arrived through a major airport, this is often issued on arrival, but it still needs to be registered at your local address within 14 days. This registration is foundational: almost everything else in Japan's admin system — bank accounts, health insurance, pension — requires your registered address and residence card number.

Get a SIM card or pocket wifi as early as possible — the airport arrival halls at Narita and Haneda have rental and SIM purchase desks immediately after customs. A working phone number is required for most bank account applications and is essential for navigating the city's transit apps, Google Maps, and LINE (Japan's dominant messaging platform).

First Month: Banking, Health Insurance, and Pension

Opening a Japanese bank account as a new resident used to require three months of residency history, but this requirement has been relaxed for many banks — Japan Post Bank (ゆうちょ銀行) and Sony Bank are generally the most accessible for new arrivals with limited Japanese ability. You'll need your residence card, passport, and registered address. Some banks now offer English-language applications and online account opening.

Enrollment in Japan's National Health Insurance (国民健康保険, kokumin kenko hoken) should happen within your first month. If you're employed by a Japanese company, your employer will handle enrollment in the corporate health insurance scheme (社会保険, shakai hoken). If you're self-employed, freelance, or on a working holiday visa, you enroll at the ward office. Premiums are income-based but are significantly lower than equivalent private insurance in most Western countries.

Finding an Apartment: The Guarantor Problem and How to Solve It

Japan's rental market has a reputation for being difficult for foreigners, and it's partly deserved. The traditional system requires a Japanese guarantor (保証人, hoshounin) — typically a Japanese citizen willing to personally vouch for you — which most newcomers don't have. The good news is that guarantee companies (保証会社, hoshou gaisha) now serve as corporate guarantors for a fee (typically one month's rent), and many landlords and real estate agencies now work with foreign tenants through these services.

Agencies specialising in foreign-resident rentals — Sakura House, Leopalace, and various local agencies in major cities — are a practical starting point for a first apartment. The standard rental contract in Japan requires a security deposit, a non-refundable "key money" payment in some areas, and the first month's rent, making upfront move-in costs equivalent to three to four months' rent in many cases.

The Things Nobody Tells You Until You're Here

Japan operates significantly on cash in a way that surprises newcomers from cashless societies. Many smaller restaurants, izakayas, and local shops are cash-only; some temples and shrines charge cash-only entrance fees; and the vending machine economy runs entirely on coins and notes. Having ¥5,000–10,000 in cash on you at all times is a practical habit rather than a preference.

The language barrier is more manageable than most people fear and more present than expat guides tend to admit. Google Translate's camera function has improved to the point where reading menus, signs, and forms is genuinely possible for a non-Japanese speaker. But navigating a ward office in Japanese, dealing with a maintenance issue in your apartment, or handling any phone-based customer service without some Japanese ability is genuinely difficult — a few months of basic Japanese before arriving will pay disproportionate dividends.
