Rockstar North's former technical director Obbe Vermeij revealed that the studio once considered giving a Japanese developer the keys to create a Grand Theft Auto game set in Tokyo. Vermeij told Rock Paper Shotgun he has a name for the studio in mind but declined to share it publicly. The project appears not to have progressed far, though recent discoveries of "Tokyo PS2" references in GTA 5's source code suggest the concept had some internal development. Rockstar's interest in breaking into the Japanese market through a localized GTA title never materialized into a released game.
