This is a partial list of notable Japanese language computer and video games that have not seen, and likely never will see, any official English language localization. This does not include games that are scheduled for official English releases in the future, or enhanced remakes of games that had their original versions officially released in English years earlier. This list includes many games that have fan translations available in some form, as well as alternate versions of games and ports for other systems (for example, the PlayStation 2 version of Tales of Symphonia (PS2) has not been released in English, whereas the GameCube version has). Some of these games have become import classics, meaning that they have a significant import audience.
For a fuller list with untranslated titles, see Japanese games/Phoenic order.
