Japan Phone Number for Foreigners:
Which Plans Actually Carry One
Almost every Japan eSIM sold to travellers is data only, and no amount of paying more adds a number to it. There are exactly two routes that do — and one of them needs a residence card.

A Japan phone number for foreigners does not come with a traveller's data eSIM: every Japan plan from the four providers we track is data only, and the number is a separate product rather than an add-on. Two routes carry one. With a residence card, the resident monthly plan — Sakura Mobile's Voice + Data SIM or eSIM from ¥2,980/month (¥3,278 tax incl.) plus a ¥5,500 activation fee, with a genuine 070, 080 or 090 mobile number, a one-month minimum and the line ready about 1–3 days after approval (5–7 if you port a number in). Without a card, the in-person route: Sakura Mobile verifies with a passport at an airport counter or its Shinjuku office, and sells a prepaid Voice + Data travel eSIM for 1 to 90 days that includes domestic calls and SMS. What a number is not is a published requirement for a bank account — Japan Post Bank asks for a residence card and a period of stay longer than three months, and names no phone number at all. All Sakura Mobile and Japan Post Bank figures read on 30 Oct 2026.

In short: if the trip is a holiday and the list is maps, messaging and translation, buy a data eSIM and stop reading — you do not need a number. If the list includes a bank, a tenancy, a job or a Japanese SMS code, you need the Voice + Data product, and which version depends on one thing: whether your status comes with a residence card.
Can a Foreigner Get a Japanese Phone Number?
Yes — on two of the six products below, and the column that decides which one applies to you is the residence card. Everything else on the row is the price of that decision.
| Product | Japanese number? | Residence card needed? | Term | Price |
|---|---|---|---|---|
| Sakura Mobile Voice + Data monthly (resident) | Yes — a 070, 080 or 090 mobile number | Yes for an eSIM by email or a SIM by delivery: a Residence Card or My Number Card showing your current address. No, if you collect in person — the company offers passport verification at an airport counter or its Shinjuku office | Minimum use one month, then rolling; published as "Month-to-month with no lock-in" | From ¥2,980/month (¥3,278 tax incl.) plus a ¥5,500 activation fee |
| Sakura Mobile prepaid Voice + Data travel eSIM | Yes — the listing states it “also gives you a Japanese phone number”, with domestic calls and SMS | No — but in-person ID verification is required, at a select airport counter or the Shinjuku office | 1 to 90 days, the ceiling on every travel product in Japan; nothing to cancel | Priced separately from the data-only travel eSIM, which is from ¥1,250 (¥1,375 tax incl.) — we quote no figure for the voice version because the company publishes none we could read |
| Sakura Mobile Data Only monthly (resident) | No | Same documents as the Voice + Data monthly plan | One month minimum, then rolling | From ¥2,480/month (¥2,728 tax incl.) plus the same ¥5,500 activation fee |
| Sakura Mobile data-only travel eSIM | No | No — the listing states no ID verification is required | 1 to 90 days | From ¥1,250 (¥1,375 tax incl.) |
| Klook Japan eSIM | No — data only — as the listing states it | No | Sold by the day; nothing to cancel | Check on Klook — its product pages block automated price reads, so we quote none |
| Airalo, Holafly and eSIM Go Japan plans | No — data only — all three, on their own pages | No | Plan lengths run in days; no contract | From $3.99 across the four providers we price |
Sakura Mobile figures are the company's own, read off sakuramobile.jp on 30 Oct 2026; each monthly price is a published “from” and the data tier moves it. The Airalo, Holafly and eSIM Go phone-number clauses come from their own pages, 22 Oct 2026, and their prices from our daily feed, checked 29 Oct 2026. The Klook row quotes its listing's own stated service type; no Klook price appears anywhere on this site because Klook blocks automated reads of its product pages. Our Sakura Mobile review goes through the travel plans in detail, and SIM card vs eSIM is the version of this comparison for a two-week trip.
Does a Travel eSIM Come With a Japanese Phone Number?
No, with one narrow exception. The four providers we price publish this plainly on their own pages: eSIM Go's Japan plans state “No SMS or voice calls included. Data only.”; Airalo's Japan plans are data only; Holafly's Japan page states there is no local phone number; and the Klook Japan eSIM listing gives its service type as No — data only. So does Sakura Mobile's own data-only travel eSIM, which is from ¥1,250 (¥1,375 tax incl.) for 1 to 90 days and states that no ID verification is required.
The exception is a different product from the same company: a prepaid Voice + Data travel eSIM, which the travel page says “also gives you a Japanese phone number” and sells with domestic calls and SMS — allowances the listing puts at up to 120 minutes on the shorter stays, rising to up to 480 minutes at 61 days and over. The thing to plan around is not the price but the process: in-person ID verification is required, at a select airport counter or the Shinjuku office. That makes it a pre-order rather than a download, which is precisely the kind of detail an AI summary will tell you exists and will not tell you to arrange before you fly.
If you have read this far and concluded that maps, messaging, translation and email are the whole of your list — which for most holidays they are — then a data eSIM is the right and much cheaper answer. Our best eSIM for Japan guide ranks them on today's prices, and does eSIM work in Japan covers the handset checks to make before buying one. Provider clauses read 22 Oct 2026; Sakura Mobile read 30 Oct 2026; prices checked 29 Oct 2026.
Do I Need a Japanese Phone Number to Open a Bank Account?
Not according to any condition we could find published. The table separates what an institution actually states in writing from what is merely difficult without a number, because the two get run together everywhere else and they are not the same thing.
| What you are trying to do | What is published (read 30 Oct 2026) | What that means in practice |
|---|---|---|
| Opening a Japan Post Bank account | Its page for foreign nationals asks for the residence card to be presented and states an account cannot be opened where your period of stay expires within three months of the application date. A student or employee ID is requested from students and employees, a Japanese-speaking companion may be asked for, and the bankbook may be posted rather than handed over. | A phone number is not among the published conditions. Sakura Mobile's own claim for its number is that you “can use” it “to open your bank account”, which is a different statement from a bank requiring one — treat the number as the thing that makes the form fillable rather than as a legal precondition. |
| Registering your address at the ward or city office | The Immigration Services Agency requires the place of residence to be notified at the municipal office within 14 days of the day you decide on it, presenting the residence card. | No phone number in the rule. But this is the step that puts an address on the card, and the address is what a resident phone plan verifies against — so the paperwork comes before the number, not after it. |
| Renting a flat or a sharehouse room | Sakura Mobile states its numbers are ones “you can use to open your bank account and rent an apartment”. | Letting agents and guarantor companies in Japan contact applicants by phone, and the application forms have a mobile field. We quote no agency's own rule here because there is no single published one to quote. |
| A part-time job application | Nothing published centrally — this one varies by employer. | In practice the form asks for a mobile number and the answer arrives as a phone call, often the same week, which is why a data-only plan makes a job search slower rather than impossible. |
| SMS verification codes from Japanese services | Nothing published centrally. | This is where a data-only plan hurts most predictably: a one-time code sent to a mobile number cannot arrive on a plan that carries no number and no SMS. A number you already hold abroad may receive it, but not every Japanese service will send to an international one. |
| An 050 internet-telephony number instead | Sakura Mobile draws the distinction itself: a 070, 080 or 090 number supports calls, SMS and emergency services “unlike 050 VoIP numbers, which are often rejected for banking and apps”. | Cheap and quick to get, and genuinely useful as a callback line. Not a substitute where the thing you are signing up to checks the prefix — which, on the company's own account of it, is often. |
One thing worth saying plainly, because it is the actual shape of the problem: the bank's published gate is not a phone number, it is a residence card and a period of stay that does not expire within three months of the application date. Different banks publish different conditions and branches apply them differently, so treat the above as quotations rather than as advice about your own application. Nothing on this page is banking or immigration advice.
What Do You Use Instead of a Japanese Bank Account?
A card that does not need one. Since the bank's own gate is a residence card and a period of stay longer than three months, there is a stretch at the start of every long stay — and the whole of every short one — where a Japanese account is simply not available. A multi-currency card covers it: Wise converts at what it describes as “the live mid-market rate, and a small, upfront fee”, and publishes free ATM withdrawals up to 250 GBP/month on a UK-registered account with 2.69% above that allowance. Allowances differ by the country your account is registered in, so read yours rather than ours. Figures read 21 Oct 2026.
It is not a replacement for a Japanese account if you are being paid by a Japanese employer — payroll goes to a domestic account, and that is the thing the residence card unlocks. It is a replacement for carrying a month of cash while you wait. Our best travel card for Japan guide compares it against the alternatives on fees, and ATMs in Japan covers which machines take foreign cards at all.
How Much Does a Japanese Phone Number Cost Per Month?
¥500 a month, as cleanly as that question is ever answered. Sakura Mobile publishes its two resident plans side by side at seven identical data tiers, and the Voice + Data column is ¥500 above the Data Only column at every single one: ¥2,980 against ¥2,480 at 5 GB, ¥3,480 against ¥2,980 at 15 GB, ¥3,980 against ¥3,480 at 30 GB, ¥4,980 against ¥4,480 at 40 GB, ¥6,980 against ¥6,480 at 60 GB, ¥8,980 against ¥8,480 at 80 GB and ¥10,980 against ¥10,480 at 100 GB. Across a year that is ¥6,000.
Two things sit outside that figure. There is a ¥5,500 activation fee on every tier of both plans, charged once — and if you are a student, the company publishes an “Additional 1,100 JPY discount from activation fee” with the coupon code “studentdiscount”, which our SIM card guide for students goes through. And calls and SMS on the resident plan are charged on top of the monthly fee rather than bundled into it, so a line used heavily for voice costs more than the grid suggests. The data tier is still the part that moves your bill most: 15 GB to 60 GB is ¥3,500 a month, seven times the price of the number itself. All read 30 Oct 2026.
Can Tourists Get a Japanese Phone Number?
Yes, but not on the product almost every tourist buys. A short-stay visitor status does not come with a residence card, which closes the resident monthly plans — and the data eSIM you bought before flying carries no number at any price. The route that stays open is the prepaid Voice + Data travel eSIM, sold for 1 to 90 days with domestic calls and SMS and verified against a passport in person at a select airport counter or the Shinjuku office. The monthly plan has the same passport route for anyone with no registered Japanese address.
The honest version of the advice, though, is that most holidays do not need one. Hotels, tours and restaurant bookings in Japan are reachable through apps, your accommodation's front desk and email; a data plan carries messaging, internet calls and translation. The cases where a tourist genuinely wants a number are narrow and specific — a long trip with domestic bookings made by phone, a work visit with Japanese colleagues who will ring you, a stay where someone has to be able to reach you without wifi. If that is you, pre-order it before you fly, because the in-person verification is the mechanism and not an inconvenience you can skip on arrival. Read 30 Oct 2026.
What If You Only Need Data After All?
Most people who search for a Japanese phone number turn out to need maps, messaging and translation rather than a line anyone will ring. If that is the conclusion you have reached on this page, the cheapest way to have all three working the moment you land is a data eSIM installed before you fly.
- ▸Klook Japan eSIM — It carries no Japanese number at all — the listing states data only — so it is here for the opposite reader: the one who came looking for a number, worked out that maps, messaging and email are all they actually need, and wants the cheap no-contract way to have them working on landing.

How Do You Get a Japanese Number, In Order?
Work out whether you need a number at all, before you buy anything
If the trip is a holiday and the list is maps, messaging, translation and email, the answer is no, and a data eSIM from $3.99 across the providers we price is the cheapest way to have all four working on landing. If anything on your list is a bank, a tenancy, a job, a clinic or a Japanese SMS code, the answer is yes and the rest of these steps apply.
Check whether you will hold a residence card
This is the fork. A mid- to long-term status — work, study, a working holiday, a family stay — comes with a residence card, which is what a resident monthly plan verifies against. A short-stay visitor status does not, and no amount of paying more changes that.
If you have no card: use the in-person route, and arrange it from home
Sakura Mobile sells both the monthly Voice + Data plan and a prepaid Voice + Data travel eSIM on pre-orders you verify in person — "Pick up at our airport counters or Shinjuku office" — with a passport instead of a card. The in-person step is the whole point of the route, so it has to be booked in advance rather than walked up to on arrival.
If you have a card: register the address first, then apply
The Immigration Services Agency gives you 14 days from deciding where you live to notify the municipal office, presenting the card; the address is printed on the reverse at that visit. Applying before that is the single most common reason a resident application stalls, because the card you are uploading does not yet show where you live.
Pick Voice + Data over Data Only, and know what the ¥500 buys
The two resident plans are ¥500 a month apart at every tier — ¥2,980 against ¥2,480 at 5 GB, ¥10,980 against ¥10,480 at 100 GB. That is ¥6,000 across a year for a line that can be rung. If you are reading this page at all, you have already decided you need that.
Allow 1–3 days after approval, and 5–7 if you are porting a number
Sakura Mobile's own figures. The eSIM arrives as a QR by email and a SIM card by delivery, so the carrier is the fast part; an MNP transfer needs a reservation number from your existing carrier before you apply, which is what stretches it. Neither figure includes the days the address registration takes.
Note the 25th on the day you sign up
The published rule is "The minimum use is just one month. You can cancel anytime by submitting a request before the 25th." Submit on the 26th or later and the contract runs one more month, because it renews automatically rather than expiring. Not a penalty — one more month's fee, from the other side of the world.

The number is a separate product — pick the right one
With a residence card, Voice + Data from ¥2,980/month and a 070, 080 or 090 number, ready about 1–3 days after approval. Without one, the passport route in person. And if data is all you actually need, an eSIM installed before you fly costs a fraction of either.
