Japan uses country calling code +81. Geographic fixed-line area codes contain one to four digits after the domestic trunk 0, while the complete geographic national significant number remains nine digits. The trunk 0 is used in Japan but omitted after +81: Tokyo 03 becomes +81 3 and Osaka 06 becomes +81 6.
The examples show a national format and the corresponding international plus format. Actual subscriber lengths can vary where noted.

City guide →Japan’s Telecommunications Bureau published a detailed national E.164 numbering plan through ITU and updated it in 2014. The plan lists hundreds of geographic fixed-line NDCs and keeps those resources separate from 050 IP-telephony numbers, 070/080/090 mobile or personal numbers, freephone and other non-geographic services.
An area code identifies a fixed-line numbering region, not an exact address or individual subscriber, and a region may include several municipalities. Area-code and subscriber-number lengths vary, so arbitrary regrouping can produce a misleading code. Mobile numbers beginning 070, 080 or 090 and IP-telephony numbers beginning 050 are non-geographic and are not included here.
Japan uses country calling code +81.
No. Remove the domestic trunk prefix 0 before adding +81.
No. It describes a numbering-plan association, while portability, forwarding and internet telephony can separate a number from the caller’s present location.
