Why get a Japan (+81) number

East Asian markets move quickly and customers expect immediate, local contact options before they commit.

A Japan number makes you look local in Tokyo and across the country, while you answer from your laptop, your mobile or a call-center dialer anywhere in the world.

Because it's a real number on the Japan telephone network, it works for normal calls and text messages — including one-time passcodes and verification SMS from apps and websites.

What's included with every Japan number

Unlimited inbound texts to your Japan number
500 outbound SMS per month included
1,000 outbound calling minutes per month included
Inbound calls without limits
Per-number SIP credentials
Call forwarding in one click
Browser-based dialer
7-day replacement guarantee
Auto-renewal — the number stays yours

Works with WhatsApp, Facebook, Google, Telegram and more

Signing up to WhatsApp, Telegram or Google with a +81 number takes a minute: enter the number in the app, then read the code in your Smart Messaging dashboard as soon as it lands.

People use Japan numbers to run a separate business profile, keep a personal SIM private, or appear local to Japanese contacts. If any app ever refuses the number in the first 7 days, you get a free replacement — that's our 7-day replacement guarantee.

Looking for a Japan virtual number?

Most people searching for a Japan virtual number want a +81 number they can use online, without a SIM card or a trip to Japan. Smart Messaging gives you exactly that — but on a real number from the Japan numbering plan, not an app-only line or a shared list.

You use it in your dashboard, in any SIP app or forwarded to your own phone, and it receives standard SMS and voice calls — which is why WhatsApp, Telegram, Google and Facebook verification codes arrive like on any mobile line. Read more: virtual number vs real mobile number.

From the United States or Canada: dial 011 81 and the 9–10-digit number. From the UK, Europe, India and most other countries: dial 00 81 and the number. From any mobile phone, +81 works everywhere.
