History
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.
