Japan phone number (+81) — real mobile, SMS & calls
Yes — you can get a real Japan mobile number (+81) online — it is assigned as soon as your payment is confirmed. It is a genuine mobile line, not VoIP: unlimited incoming SMS, 500 outgoing texts and 1,000 calling minutes a month, from $1.80/month on the 12-month plan. Sign up with just an email, pay in USDT or USDC and keep it as long as you renew.
Japan runs on LINE, and many domestic services, from PayPay to Mercari, ask for a Japanese mobile number during sign-up. Because tourists usually cannot get a voice SIM, a +81 number is a practical option for learners, collectors and people planning a move.

Keep your Japan number as long as you want
A Japan number is only useful if it is still yours next year. LINE and X — and most banks, marketplaces and exchanges — send codes to the number again when you switch phones, reset a password or log in from somewhere new.
Renew for 1, 3, 6 or 12 months at a time (from $1.80/month on the 12-month plan; every term price is shown at checkout) and the same +81 number stays on your account for as long as you want. Nobody else is assigned it while you hold it, and auto-renew from your wallet means it never lapses by accident.
Travelling, moving or living abroad
Voice SIM contracts in Japan generally require a residence card, so short-term visitors usually only get data-only SIMs or eSIMs.
With PhoneBorn you skip the SIM counter entirely: the Japan number lives in your browser, so it works before you land, while you are there and after you leave — no roaming charges on incoming SMS.
Students and working holiday: People on study or working holiday visas in Tokyo and Osaka use a Japanese number for part-time job applications and apartment hunting.
FAQ
Japan phone number FAQ
How do Japan mobile numbers look?
Japan mobile numbers are written 090 xxxx xxxx → +81 90 xxxx xxxx — 10 digits after the +81 country code. When an app asks for your number, pick Japan (+81) and enter the digits without any leading trunk 0.
Can I use a Japan number for WhatsApp?
Yes. It is a real mobile number, so WhatsApp can verify it by SMS or by voice call — both arrive in your PhoneBorn inbox. If you only need one WhatsApp code, a single-use OTP number for Japan costs $1.90. For an account you plan to keep, a plan you renew is the safer choice because WhatsApp re-verifies when you change phones.
Can I make and receive calls on a Japan number?
Yes. Every plan includes 1,000 outgoing calling minutes a month and unlimited incoming calls, plus unlimited incoming SMS and 500 outgoing SMS. Voice-call verification codes are therefore covered too.
Which apps work with a Japan number?
Works with WhatsApp, Facebook, Google, Telegram, Instagram, TikTok and 110+ apps — and if it ever doesn't in the first 7 days, we replace it free. Popular locally: LINE, X, Instagram, YouTube. Each app sets its own rules on which numbers it accepts; real mobile numbers pass the line-type checks that block VoIP numbers, and the 7-day replacement guarantee covers you if one doesn't.
What if my Japan number doesn't work for my app?
You're covered by the 7-day replacement guarantee: if your Japan number doesn't work for WhatsApp, Facebook, Google, Telegram or any app you need within 7 days of purchase, press “Replace number” in your dashboard to get a new Japan number for free — instantly, up to 3 times, and your plan and expiry date stay the same. Never used it? If the number hasn't sent or received a single SMS or call, you can take a full refund to your PhoneBorn balance instead within the same 7 days. Single-use OTP numbers are refunded automatically if no code arrives.
Do I need ID or a Japan address?
No. You only need an email address — no passport, no local address and no residency. That is the main difference from a local prepaid SIM. Voice SIM contracts in Japan generally require a residence card, so short-term visitors usually only get data-only SIMs or eSIMs.
How much does a Japan phone number cost?
A number you keep costs from $1.80/month on the 12-month plan; 1-, 3- and 6-month terms are also available — see all term prices at checkout. A single-use OTP number that receives one code costs from $0.95. Prices are in USD and you pay from a crypto-funded wallet.
Can I use the number outside Japan?
Yes. The number works from anywhere with an internet connection — you read SMS in the web dashboard, so there is no roaming and no SIM. Handy whether you are in Tokyo or on the other side of the world.
