This page covers Japan virtual numbers for business and carrier use — numbers that route inbound calls into phone systems, contact centres, and platforms. It is not about consumer second-line apps. If the terms are new, see what a virtual phone number is and how the number types differ.

Japan number types

In Japan, a number carries the country code +81 followed by a national destination number; the exact length and format depend on the number type and area. We currently offer local (geographic) and toll-free:

  • Local — local (geographic) numbers in Japan.
  • Toll-Free — toll-free numbers in Japan.

Availability by type is set by the local regulator and carriers; the live stock for Japan is shown in the coverage table and at the point of order.

How Japan numbers reach your system

When someone dials your Japan number, the call crosses the PSTN (Public Switched Telephone Network) to the carrier holding the range, which hands it to Temptera. We deliver it to you as a SIP (Session Initiation Protocol) call carrying the dialled number, and your PBX or softphone routes it to the right agent, queue, or IVR. Because the routing is software, one Japan number can ring a whole team or map to a single user, with failover to a second destination.

What you'll need to order

Requirements depend on the number type. Some Japan ranges can be bought with no documents; others require identity, a local address, or proof of local presence. This is set by the range, not by the provider, and exists as consumer protection (see how virtual number regulations and KYC work). The exact requirement for your chosen Japan type is shown before you confirm the order.

How to get a Japan number

  1. Choose the number type for your use case — local for in-market presence, national for a countrywide line, toll-free to carry the caller's cost.
  2. Check the documentation class shown for that Japan range.
  3. Order from live inventory in the portal.
  4. Point the number at your SIP endpoint or PBX and add a failover.
  5. Place a test call and go live.

Frequently asked questions

What is a Japan virtual phone number?

It is a Japan number (country code +81) provisioned in the cloud and delivered over SIP, rather than on a physical line. Inbound calls route to your PBX, softphone, or a forwarding destination you choose, so you can answer Japan calls from anywhere.

Which Japan number types can I get?

For Japan we offer local (geographic) and toll-free. Availability by type is set by the local regulator and carriers, and the current stock is shown at the point of order.

Do I need documents to get a Japan number?

It depends on the number type. Some ranges need no documents; others require identity, a local address, or proof of local presence. The exact requirement for Japan and your chosen type is shown before you order.

How quickly can a Japan number go live?

Undocumented inventory activates within minutes; ranges that require verification take longer while documents are checked. Once active, you point the number at your SIP endpoint and start receiving calls.
