About Japan Phone Numbers
Japanese mobile numbers start with 090, 080, or 070, followed by 8 digits. Landlines vary by area code length (3-5 digits) plus subscriber number (4-7 digits).
How to Dial Japan Phone Numbers
To call a Japan phone number, the exact format depends on where the call starts. Domestic mobile calls usually keep the leading 0, while international calls to Japan use the +81 country code instead.
- Within Japan: Dial the full national number, including the leading 0 for standard domestic calls.Example:
090-1234-5678 - From abroad to Japan: Dial +81 followed by the national number without the leading 0.Example:
+81 90-1234-5678 - From Japan to other countries: Dial 010, then the country code, then the full phone number.Example:
010 1 212 555 0123
Note: Japanese mobile numbers in this format appear domestically with a leading 0, but that prefix is dropped in international format.
