Japan Virtual Number
A +81 number gives you a Japanese line without the residence card Japan normally demands for a SIM, a genuine rarity for anyone outside the country. It takes minutes to activate, runs on unrestricted two-way texting and calling, and is funded entirely in crypto with no ID.
One price for the number. Everything else is unlimited.
You pay to hold the number, and that is it. Sending and receiving texts, taking calls, and dialling out are all included with no per-message or per-minute charge. Top up in crypto, and your number stays live as long as your plan is active.
- Unlimited SMS, send and receive, verification codes included
- Unlimited calls, inbound and outbound, no per-minute meter
- Keep the same number, month to month or by the year
A Japanese number, normally the hardest to get
A Japanese phone number is famously hard to obtain as a foreigner: carriers generally require a residence card and a local address, which rules out tourists, new arrivals, and anyone dealing with Japan from abroad. A virtual +81 line is the uncommon way around that, a genuine Japanese number ready in minutes, with no residence card and no shop.
Both directions carry no cap: a mobile or a Tokyo 03 landline can be the number that receives Japanese verification codes, the one a Mercari buyer contacts, and the one a service saves, answered wherever you are.
There is no residence-card trail behind it either: crypto settles the cost, the +81 number shows up in your dashboard, and nothing about it is registered to your name.
Codes land the second they are sent
Point any signup at your Japan number and the verification SMS arrives in your dashboard right away, ready to copy. No SIM to swap, no roaming, no waiting. Replies and calls go back out from the same number, all included.
- Instant delivery of SMS codes to your account
- Reply and place calls from the same Japan line
How Japan numbers work
Your plan is one Japan +81 number with unlimited texts and calls, both ways. We assign it from the ranges available to us, so the format is not something you pick at checkout. Here is what each kind of Japan number looks like.
Mobile numbers
A +81 mobile line on the 070, 080, or 090 ranges, what Japanese apps and services text a code to.
City numbers
A city line, so 03 reads as Tokyo and 06 as Osaka, for a fixed local presence.
Toll-free numbers (coming soon)
A 0120 or 0800 free-dial line, the free-to-call number Japanese customers know and trust.
Which apps accept it
A Japan +81 number works for most sign-ups. A few strict apps, including some messengers and banks, reject virtual numbers by policy, so here is what to expect by type of app.
No provider can promise every app accepts every number, and app policies change. For accounts you will log into again, keep your Japan number rather than using a one-time code, so later login codes still reach you.
What people use a +81 number for
Get a Japanese number at all
Japanese carriers want a residence card most foreigners do not have. A +81 virtual line gives you a real Japanese number without it, which is otherwise very hard to arrange.
Sell and shop on Mercari
Japanese platforms like Mercari expect a +81 number to verify. This line receives their codes without a resident SIM or address.
Register on LINE and services
Japan runs on LINE, and many Japanese services want a Japanese number at signup. A +81 line lets you register where a foreign number is refused.
Look local to Japanese customers
A Tokyo 03 line or a 0120 free-dial number on your site reads as an established local business, with free callbacks over VoIP.
Good to know about Japan numbers
The residence-card barrier you avoid
Japanese carriers generally require a residence card and local address for a SIM. A virtual number needs neither, which is why it is such a useful workaround.
Japan runs on LINE
Unlike most of the world, Japan's default messenger is LINE, and a Japanese number helps when registering it and the many services that assume a +81 line.
How the numbers read
Japanese mobiles use the 070, 080, and 090 prefixes, while 03 marks Tokyo, 06 Osaka, and 0120 is the classic free-dial.
No residence card required
Since the number runs on our network rather than a Japanese carrier, a Tokyo line rings through from Zurich or Bangkok with nothing more than a data connection.
Why a Japanese number is so hard to get, and how this helps
Japan is one of the hardest developed countries in which to obtain a phone number as a non-resident. Major carriers ask for a residence card, a local address, and often a Japanese payment method, which shuts out tourists, incoming students and workers before they arrive, and anyone abroad who needs a Japanese line for an account or a service.
A virtual +81 line is the practical exception. It gives you a genuine Japanese number for verification, LINE and marketplace signups, and local presence, with no residence card, no address, and no shop. It does not replace residency where Japanese law separately requires it, but for a working Japanese number it removes a barrier that otherwise stops people cold.
