Japan SIM Card for Working Holiday:
The Order It Has to Happen In
The residence card gates the address, the address gates the phone number, and the number gates the bank and the job. Here is what to buy at each step, and what to use while you wait.

The Japan SIM card for a working holiday is a resident monthly plan with a Japanese phone number, and the English-language option we link is Sakura Mobile: its Voice + Data SIM or eSIM is published from ¥2,980/month (¥3,278 tax included) for 5 GB up to ¥10,980 for 100 GB, with a ¥5,500 activation fee on every tier, a Japanese 070, 080 or 090 number and a one-month minimum. What a working holiday has to plan around is not the price but the order: the Immigration Services Agency issues your residence card at immigration at seven airports, you must notify your place of residence at the ward or city office within 14 days of deciding on it, and only then does the card show the address a resident plan verifies against — which is also what Japan Post Bank wants before it opens an account. Cover the fortnight in between with a travel eSIM from $3.99, or take Sakura Mobile's own “Verify with your passport” route and start the monthly plan in week one. No Japanese bank account is needed either way: international cards are accepted. All figures read off sakuramobile.jp, moj.go.jp/isa and jp-bank.japanpost.jp on 29 Oct 2026.
Plan to get
Voice + Data, from ¥2,980/mo
One-off activation
¥5,500
Address deadline
14 days to register it
Bank account needed?
No — international card
In short: fly in on a travel eSIM, register your address inside the 14-day window, then sign the Voice + Data plan — because the number is what the bank, the sharehouse and the part-time job all ask for, and it is the one thing no travel product in Japan sells. If your address will not be fixed for a few weeks, the passport-verification route on the same monthly plan starts it sooner.
What SIM Card Should You Get for a Working Holiday in Japan?
A resident Voice + Data plan. Below is the full published grid for both of Sakura Mobile's resident plans, because a working holiday signs a tier for a year rather than buying a plan for a trip — and the second column is what a Japanese phone number costs at every size.
| Monthly data | Voice + Data (tax incl.) | Data Only (tax incl.) | Price of the number |
|---|---|---|---|
| 5 GB | ¥2,980 (¥3,278) | ¥2,480 (¥2,728) | ¥500/month |
| 15 GB | ¥3,480 (¥3,828) | ¥2,980 (¥3,278) | ¥500/month |
| 30 GB | ¥3,980 (¥4,378) | ¥3,480 (¥3,828) | ¥500/month |
| 40 GB | ¥4,980 (¥5,478) | ¥4,480 (¥4,928) | ¥500/month |
| 60 GB | ¥6,980 (¥7,678) | ¥6,480 (¥7,128) | ¥500/month |
| 80 GB | ¥8,980 (¥9,878) | ¥8,480 (¥9,328) | ¥500/month |
| 100 GB | ¥10,980 (¥12,078) | ¥10,480 (¥11,528) | ¥500/month |
| Activation (one-off) | ¥5,500 | ¥5,500 | — |
Every figure is Sakura Mobile's own, read off its published monthly price list on 29 Oct 2026; both plans are stated as “Month-to-month with no lock-in” with a minimum use of one month. The activation fee applies once per line, and the company publishes a ¥1,100 student discount on it against the coupon code “studentdiscount”. Our long-term stay guide makes the wider resident-versus-travel case for any stay over 90 days, and the Sakura Mobile review goes through the travel plans in detail.
Can You Get a Japanese Phone Number on a Working Holiday Visa?
Yes — a working holiday is a mid- to long-term status, so it comes with a residence card, and a residence card is exactly what a resident plan verifies against. The catch is never eligibility. It is that each row below is locked by the row above it.
| Step | When | What the official source says (read 29 Oct 2026) | What it unlocks |
|---|---|---|---|
| 1. Land, and collect the residence card | At the airport, on the day you arrive | The Immigration Services Agency issues the residence card when landing permission is granted at New Chitose, Narita, Haneda, Chubu, Kansai, Hiroshima and Fukuoka. Arrive anywhere else and the card is posted to you after step 2 instead. | Nothing — but the card has no address on it yet |
| 2. Register the address at the ward or city office | Within 14 days of deciding where you live | The Agency's rule is a deadline, not a suggestion: notify your place of residence at the municipality's office within 14 days of the day you decide on it, bringing the residence card. The address is then printed on the back of the card. | The Voice + Data application, and the bank |
| 3. Sign the Voice + Data plan | Once the card shows that address | Sakura Mobile's resident Voice + Data plan is published from ¥2,980/month with a Japanese 070, 080 or 090 number and a ¥5,500 activation fee, and its accepted documents "must be registered with your current address". | The bank, most job applications, most Japanese checkouts |
| 4. Open the bank account | After the number exists | Japan Post Bank asks for the residence card and states it cannot open an account where your period of stay expires within three months of the application date — which is a reason to do this early in a one-year working holiday, not late. | Getting paid by a Japanese employer |
| 5. Apply for the job | With a number and an account in hand | A part-time application in Japan asks for a mobile number on the form and is answered by a phone call, often the same week. This is the end of the chain, and it is why the number is worth hurrying. | — |
One point worth making plainly, because it is the thing that surprises people arriving from countries where a prepaid number is a supermarket purchase: in Japan the mobile number is the identity document of everyday life. A part-time job application asks for one on the form and is answered by a phone call. A sharehouse contract asks for one. So does a clinic, a parcel redelivery and the two-factor code from every Japanese online service. A year of data without a number is not a cheaper version of the same year.
What Can You Use Before You Have a Residence Card Address?
There are four routes, and only one of them is finished before you fly. Which you need depends on a single question: is your Japanese address already fixed, or are you arriving to look for one?
| Route | What it verifies with | What you get, and the catch |
|---|---|---|
| Resident plan, verified with a residence card | A Residence Card or My Number Card with "a registered Japanese address" | The full product: a Japanese number, any tier from 5 GB to 100 GB, eSIM QR by email or a SIM delivered. Needs step 2 done first. |
| Resident plan, verified with a passport | A passport, where you have no registered Japanese address yet | Sakura Mobile's own plan page offers this as the alternative route — "Verify with your passport" — which is what makes a monthly plan possible in week one. Collect at an airport counter or the Shinjuku office. |
| Travel eSIM, bought before you fly | Nothing but an eSIM-capable handset | From $3.99 across the four providers we price, installed at home, working the moment you land. Data only, and capped at 90 days — the bridge, not the plan. |
| Monthly Pocket WiFi | A passport at the airport counter, or an address for delivery | Published from ¥4,980/month for 100 GB and ¥6,480 for 200 GB, on SoftBank 4G/LTE, with no two-year contract — the option if your handset cannot take an eSIM at all. |
The honest planning advice is to decide between rows two and three before you book the flight, because they imply different arrival days. The passport route gets the monthly plan and the number started in week one but needs you at an airport counter or the Shinjuku office to collect; a travel eSIM needs nothing and nobody, but it is data only and runs out at 90 days — which is less than a quarter of a working-holiday year. Rental specs and eSIM prices carry their own dates: eSIM prices checked 28 Oct 2026, everything else read 29 Oct 2026.
What Should You Book Before You Land?
A working-holiday arrival is not a holiday arrival: you come with a year of luggage, no address on your card and a two-week clock already running. These are the three things worth having in hand before immigration rather than after it.
- ▸Klook Japan eSIM — A Japanese number needs a residence card registered to an address, and the Immigration Services Agency gives you 14 days from deciding on that address to register it — so your first fortnight online is a travel product whatever plan you eventually sign. See eSIM options on Klook →
- ▸Private transfer, Haneda or Narita ⇄ Tokyo — A working holiday arrives with a year of luggage rather than a cabin bag, and the Narita Express has no space for two hold cases at rush hour — this is booked to a street address, which is what you have on day one instead of a station name. Check a private airport transfer →
- ▸Shared transfer, Narita or Haneda → Tokyo — The seat-price version for one person: still door-to-door to a central Tokyo address, which matters on the day your sharehouse check-in is a time slot rather than a 24-hour desk. Check a shared airport transfer →

Do You Need a Bank Account to Get a SIM Card in Japan?
No — and the direction of that dependency is the single most useful thing on this page. The bank wants the phone; the phone does not want the bank.
| How you pay | What is published (read 29 Oct 2026) | What it means in week one |
|---|---|---|
| International credit or debit card | Sakura Mobile states it accepts "most credit and debit cards, including international ones", naming VISA, MasterCard, Discover, JCB, AMEX and Diners Club. | The route that works before a Japanese bank account exists. Approval still sits with your card issuer. |
| Cash at a convenience store (Smart Pit) | Monthly payments made with a Smart Pit number at Lawson, Family Mart, Mini Stop and others. | It carries a deposit on the resident plans: ¥20,000 on Voice + Data, or two months' fees on Data Only and Pocket WiFi. |
| Japanese bank account | Not required. The company states plainly: "You do not need a Japanese bank account or a local credit card." | Which is the clause that breaks the circle — the bank wants the number, and the number does not want the bank. |
The bank side has a condition worth reading before you arrive. Japan Post Bank's own guidance for foreign customers asks for the residence card and states that an account cannot be opened where your period of stay expires within three months of the application date. A one-year working holiday clears that comfortably at the start and not at all at the end — so if you want a Japanese account for wages, open it in your first months, not your last. Read on jp-bank.japanpost.jp on 29 Oct 2026. Our travel card guide covers what to use for spending in the meantime.
Which Tier Should You Sign for a Year?
The grid runs 5 GB to 100 GB on both plans, and one question moves the answer more than any other: does the place you live have its own internet? With a home line, a phone-only month sits inside 15 GB — ¥3,480 on Voice + Data. Without one, a tethered laptop for work, study or job applications pushes the same month towards 60 GB, which is ¥6,980. Across a working-holiday year that difference is about ¥42,000, which is more than the gap between any two sensible home-internet decisions.
So make the home decision first. A sharehouse usually includes a line in the rent; a private flat on a one-year lease usually does not, and a Japanese fibre order takes weeks rather than days. Our guide to home internet for foreigners has the published prices and installation lead times for that side, including the no-installation router that is the usual answer on a one-year tenancy. Then size the SIM around what is left.
The other half of sizing is the activation fee, which is ¥5,500 once per line and does not scale with the tier. It makes switching tiers mid-year cheap — you are changing a plan, not opening a line — so there is no reason to over-buy on day one. Start at a tier you are confident in and move up once you know what a real month looks like.
How Do You Set This Up, In Order?
Buy a travel eSIM before you fly, and install it at home
Install the profile with the line switched off so you land with working data rather than hunting an airport SSID with two cases. It costs from $3.99 across the four providers we price, there is no contract and nothing to cancel. This is the only part of the whole sequence you can finish before leaving.
Collect the residence card at immigration, and check what is on it
At the seven airports the Immigration Services Agency names, the card is issued when landing permission is granted. Look at the back: the address field is blank, and that blank field is what stops a Voice + Data application today.
Decide whether you can wait for the number
If your sharehouse or dorm address is already fixed, the fastest path is to register it, then apply once. If it is not — a fortnight in a hostel while you view rooms is the normal working-holiday arrival — take the passport-verification route on the monthly plan, or run a travel eSIM and apply later. Sakura Mobile publishes both: "Residence Card / My Number Card" with an address, or "Verify with your passport" without one.
Register the address inside 14 days
Take the residence card to the ward or city office for the municipality you live in and file the notification of place of residence. The Agency's deadline is 14 days from the day you decide on the address, and the card comes back with it printed on the reverse. Everything downstream — the plan, the bank, the job — unlocks here.
Pick the tier against a year, not a fortnight
Both resident plans run 5 GB to 100 GB. The thing that moves the answer on a working holiday is whether the flat has its own internet: on a plan with no home line, a tethered laptop turns a 15 GB month into a 60 GB one, and 60 GB of Voice + Data is ¥6,980/month against ¥3,480 for 15 GB. Factor the ¥5,500 activation fee in once, at the start.
Note the 25th on the day you sign up
The published rule is one sentence — "The minimum use is just one month. You can cancel anytime by submitting a request before the 25th." — and submitting on the 26th or later runs the contract one more month. A working holiday has a known end date, so put the 25th of your departure month in a calendar now rather than in the week you are shipping boxes home.
