1.1 Unveiling the Structure: Dissecting a Japanese Phone Number
Unlike many countries, Japanese phone numbers have a unique 11-digit format. Let’s break down this seemingly complex structure into its constituent parts:
- Country Code (+81): This universally recognized prefix signifies Japan on the international stage. When dialing a Japanese phone number from abroad, you’ll always include this code before the remaining digits.
- Area Code (3 digits): This segment pinpoints the geographic region or carrier associated with the phone number. Area codes can range from two to three digits, with shorter codes typically assigned to more populated areas. Examples include:
- Tokyo (03)
- Osaka (06)
- Kyoto (075)
- Fukuoka (092)
Important Note: While writing phone numbers within Japan, omitting the leading zero (0) from the area code is increasingly common. However, when dialing from outside the country, you’ll still need to include it.

Mobile Network Operator (MNO) Prefix (1 digit): This Loan Database single digit identifies the mobile network operator (carrier) that issued the phone number. Common MNO prefixes for mobile phones include:
- 0 (docomo)
- 080 (au)
- 070 (SoftBank)
-
090, 080, or 070 (Rakuten Mobile – recent entrant)

Subscriber Number (7 digits): This unique seven-digit sequence identifies the individual phone number holder within the specific network.
