Technical info on Japanese phone numbers

In Japan, phone numbers consist of 10 digits and are structured into three groups: the area code, the city code, and the subscriber number. The area code is a 2 or 3 digit number that identifies the region of the country, while the city code is a 1 or 2 digit number that specifies the city or district within that region. The subscriber number is a 4 or 5 digit number assigned to each individual phone line.

To call a phone number in Japan from overseas, you must first dial the country code, which is +81, followed by the area code and the subscriber number. Some mobile phone numbers in Japan may begin with the prefix "080" or "090," which indicate the type of mobile service provider.

The government agency in charge of phone numbers in Japan is the Ministry of Internal Affairs and Communications (MIC). They oversee the allocation and management of phone numbers and other communication-related resources in the country. There were major changes to the way the country handles VoIP phone numbers in late 2022/early 2023.
