This page provides a list of area codes in Japan published by the Ministry of Internal Affairs and Communications as of March 1, 2023. It explains that number divisions indicate regions where calls can be made using local area codes, and local area codes are designated by telecommunications carriers. The notation like "CDE," "DE," and "E" indicates the number of digits in local area codes. For domestic calls, the prefix "0" must be dialed before the area code. The page offers the list in Word and PDF formats, along with related information on number portability and other telecommunications numbering systems.
