Japan
The Japanese station prefix for radio and television stations is JO followed by its own unique two letters; the last letter in the latter part of the callsign identifies the ownership of the station, for example the letter X indicates that it is a commercial TV station such as JOEX-TV for TV Asahi and JOCX-TV for Fuji TV while the letter R indicates that it is a commercial AM radio station such as JOKR for TBS Radio.
FM radio and TV stations have the -FM (FM radio), -TV (analogue television), -DTV (digital television), -TAM (audio multiplex), -TCM (analogue TV teletext multiplex), -TDM (analogue TV data multiplex) and -FCM (FM radio data multiplex) suffixes after their callsigns, similar to the North American practice, except for AM radio stations.

- DZ & DW for Luzon, except DZ for Palawan
- DY for the Visayas, including Palawan and Masbate
- DX for Mindanao
DW is now also used for stations in Luzon. Out of circumstance, DZ is mostly AM band, while DW is FM band. Other call sign prefixes assigned to the Philippines are DU, and DV.
