New to Japan Guide

A practical guide to setting up life in Japan in the right order, from the first essentials to the common friction points that come next.

Start with the checklist at the top, then keep going if you want the reasoning, practical steps, and official links in one place.

This page now works as both the quick checklist and the main life-setup guide, so you do not have to jump between two overlapping pages.

Problem

Many newcomers can find summary information in English, but still get stuck when a task depends on a registered address, a working phone number, a bank account, or an in-person visit they did not plan for.

In plain English

This guide is the detailed companion to the New to Japan checklist. Use it when you want to understand not just the order, but also why each step matters and where people get stuck.

Setting up life in Japan is usually not hard because information is completely missing. It is hard because the steps depend on each other, and those dependencies are easy to underestimate when you have just arrived.

You can often find overview articles in English, but still not know which office to visit, what to bring, whether your name format will match, or which step still has to be done in person. That is where many people lose time.

The fastest way to make progress is to think in order, not in isolated tasks. In practice, your address record, phone number, bank account, payment method, and everyday contracts all connect to each other.

1. Why setting up life in Japan feels difficult

The main difficulty is not only language. It is the fact that your next step often depends on the previous one being done correctly. If your address is not settled, later identity checks and deliveries become harder. If you do not have a phone number yet, banking or contract follow-up can stall.

Another common issue is that some tasks look online-friendly until you reach the critical moment. You may be able to read about a procedure online, or even start it online, but still need to appear in person for address registration, gas opening, or identity checks.

Official information also exists in English more often than many people expect, but it is not always the page you find first. In some areas, blog posts and intermediaries rank above the official source, so people understand the overview but miss the exact requirements or exceptions.

Your address, residence status, and identity documents affect later steps.
Some core tasks still require in-person visits even when the search journey starts online.
Official requirements can be harder to find than summary articles.
Small mismatches in name, address, or documents can create repeat visits.

2. The correct order to set up life in Japan

The safest order is usually: settle your address, complete resident registration, secure a usable phone number, open a bank account, stabilize your payment methods, and then move into utilities, insurance, and other daily-life contracts.

This order matters because each step makes the next one easier. Address registration supports identity checks. A working phone number helps with application follow-up. A bank account supports salary, bills, and later card payments. Once those basics are stable, service comparisons become much more realistic.

Register your address first so your later applications are built on a stable record.
Get a SIM or phone number early because follow-up calls, SMS, and verification often depend on it.
Open a bank account before you assume every later contract can use cards or cash.
Set up payment methods after banking so rent, utilities, and subscriptions do not become ad hoc.
Handle utilities and health insurance once your core identity and payment base are stable.
Add education, work, or category-specific services after the essentials are under control.

3. Common mistakes foreigners make

Most mistakes come from treating each task as separate. In reality, the biggest delays usually happen when a person tries to move faster than the dependency chain allows.

Assuming everything can be completed online.
Starting banking or other applications before the address is fully settled.
Getting the phone-number and bank-account order wrong for the provider they chose.
Using inconsistent name or address formats across documents and forms.
Going to a counter without confirming the required documents first.

Step by step

A simpler application path

Step 1

Register your address (moving-in notification)

What to do

Submit a moving-in notification (tennyuu-todoke) at your city or ward office within 14 days of arrival. Bring your residence card (original) and passport — many offices ask for both. Missing the deadline can result in a fine of up to 50,000 yen.
Request 1-2 copies of your resident record (juminhyo) on the same visit — banks and SIM providers may ask for it. Also confirm how your My Number notification will be delivered.
Write down the exact registered address (block, building name, room number) and reuse the same format on every later application.

Why it matters

Address registration is a legal obligation. Your registered address becomes the base for every later identity check, mail delivery, bank application, SIM contract, and insurance enrollment. Delay here blocks everything downstream.

What you need

Residence card (original — copies are not accepted)
Passport
Your new address in full detail (building name and room number). Bringing your lease contract helps
City hall counters are mostly in Japanese. Some large cities offer multilingual support windows

Common problems

Bringing only the residence card and being turned away for not having your passport
Using one address format at city hall and a different one on later applications
Thinking an online moving-out procedure replaces the in-person moving-in step
Not knowing about the 14-day deadline and delaying the visit

Practical tip: Write down one consistent version of your address right after registration and reuse it everywhere else.

Step 2

Get a SIM card / phone number

What to do

Decide whether you need a voice SIM, data SIM, or eSIM based on how soon you need a working Japanese number.
Check the provider's identity and payment rules before you start the application.
Confirm that your phone can support the plan you choose and test SMS after activation.

Why it matters

A working phone number is often part of the next layer of life setup. It helps with bank follow-up, contract communication, verification, and daily coordination once you begin other applications.

What you need

Residence card and any supporting address documents the provider requests
A payment method that matches the provider's application route
A compatible device if you want eSIM or immediate activation
English support varies by carrier and shop. Some MVNOs offer English online applications

Common problems

Applying before address registration is done and failing identity verification
Provider rules differing on what identity or payment proof is accepted
Trying to rely on an option that does not actually provide the voice or SMS functions you need
Getting stuck between providers that want a card and services that want a phone number first

Practical tip: If your long-term contract is blocked, secure a workable temporary option first and switch once your core documents are in place.

Step 3

Open a bank account

What to do

If you have been in Japan less than 6 months, you are classified as a 'non-resident' under the Foreign Exchange Act, and most major banks will not open an account. Japan Post Bank (Yucho) is relatively more accessible, but non-resident accounts have restrictions on transfers and ATM usage. Check the 6-month rule first and pick a bank you can qualify for today.
Check each bank's specific requirements: employment proof, phone number, identity verification method. These vary significantly between banks.
Make sure your name and address match your residence card exactly before applying. Mismatches get rejected at the counter.

Why it matters

Banking is where salary, rent, utility payments, and later card repayments all connect. Without it, almost everything in daily life stays as a cash workaround.

What you need

Residence card (original)
Address information matching your current registration (some banks ask for a resident record)
A usable Japanese phone number (required by some banks)
A personal seal (inkan) or signature — most banks accept signatures, but some require a registered seal. Seals can be bought at 100-yen shops, but check if the bank accepts them
English support varies widely by bank and branch. Some online banks offer English interfaces

Common problems

Not knowing about the 6-month rule and being turned away at a major bank
Assuming every bank treats newcomers the same way and not checking specific requirements
Choosing a bank that requires a phone number before setting up a SIM
Not having a personal seal (inkan) and getting stuck at the counter — foreign names are rarely stocked at 100-yen shops. Order a katakana or romaji seal online if needed, or choose a bank that accepts signatures

Practical tip: Do not compare only by brand familiarity. Compare by the exact requirements you can satisfy today.

Step 4

Set up utilities

What to do

Confirm whether your building uses individual contracts or already includes some utilities.
Arrange electricity and water as early as possible and book any gas opening visit that requires you to be present.
Set the payment method after checking whether the provider accepts cards, bank transfers, or another route.

Why it matters

Utilities are basic life infrastructure, not an optional extra. If they are not ready when you move in, the rest of your setup gets more stressful immediately.

What you need

Your address and move-in date
A phone number or contact method providers can reach
A payment method you can actually complete

Common problems

Gas opening requires an in-person visit (mandatory safety inspection). Next-day or same-day booking is sometimes possible, but slots fill up fast during peak season (March-April). Book early and be home for 30-60 minutes
Contacting the wrong provider because the contract type was not checked first
Leaving payment setup unfinished after the service start request
Phone reservations may be Japanese-only. Check if the gas company has an English inquiry line before calling

Practical tip: Gas is the bottleneck — book the opening visit as soon as your move-in date is set. Electricity and water are typically easier to arrange, but buildings with smart meters may require advance setup for electricity too.

Step 5

Learn health insurance basics

What to do

Confirm whether your health insurance comes through your employer (shakai hoken) or through your municipality (national health insurance / kokumin kenko hoken). If you are not covered by an employer, you must enroll at your city office within 14 days of moving in.
Check what proof of coverage you should carry when you need medical care (My Number insurance card, qualification confirmation letter, etc.).
Understand that changing jobs, moving, or changing residence status can trigger an insurance switch. If you miss the notification, you will not have a card to show, and medical costs must be paid in full upfront (reimbursement is possible but not guaranteed).

Why it matters

Health insurance is easy to postpone until something goes wrong. A basic understanding reduces confusion around enrollment, what to bring, and what happens if your status changes. Without coverage, medical costs are 100% out of pocket.

What you need

Your residence and work-status details
Whatever proof of coverage or eligibility currently applies to you
A plan for how you will confirm insurance if you need medical care quickly
City hall insurance counters are mostly in Japanese. Bring a Japanese speaker or use translation apps if needed

Common problems

Not being sure whether employer insurance or municipal insurance applies
Being unclear on what to show at a clinic or hospital
Missing a switch notification when moving or changing jobs — without a valid card, you pay 100% upfront at the clinic

Practical tip: Do not wait until your first clinic visit to learn what document or card you should present.

Notes

Exact documents and deadlines can vary by municipality, provider, employer, or building.
Keep one consistent version of your name and address across forms, contracts, and support calls.
Do not assume that online information means the whole procedure is online from start to finish.
Save screenshots, booking confirmations, and receipts so you can recover faster if something stalls.

FAQ

New to Japan FAQ

Short answers for people who are still figuring out the first steps.

Is this a full legal checklist for every city in Japan?

No. This is a practical guide covering the common early tasks and their order. Exact documents and procedures vary by city, employer, and housing situation, so always check the official page before visiting a counter or submitting an application.

Should I think about credit cards immediately?

No. Complete address registration, phone number, and bank account first. Credit card applications involve a screening process, and you are more likely to be approved once your basic life infrastructure is stable.

What if I already finished some of these steps?

Skip them and move to the next category you need. However, double-check that your address format and name spelling are consistent across all completed steps — mismatches are a common cause of problems later.
