Sony claims to have sold more than six million PlayStation 4 consoles since launching the videogame console in November.
The global sales figure includes 370,000 PS4 consoles snapped up in Japan since they launched there on February 22.
The long-awaited Japanese launch came after an impressive debut in the United States and Europe, offering a ray of hope to Sony after years of gloomy sales of its key consumer electronics goods.
Andrew House, President of Sony Computer Entertainment, said player response to console features for sharing game play and connecting in online matches has been "phenomenal".
Industry trackers have the PS4 outselling the new-generation Xbox One that US rival Microsoft fielded in November
Sony's fellow Japanese rival, Nintendo, launched its new Wii U console in late 2012. It took more than a year for the video game giant to sell 5.86 million units.
PS4, Wii U and Xbox One are fighting to be at the heart of digital home entertainment at a time when consoles are under intense pressure to prove their worth as people increasingly turn to smartphones or tablets for games and videos.
Sony's gaming division has emerged as a potential saviour for the once-mighty giant, which is struggling to reinvent itself in the digital age, having been left in the dust by nimbler rivals such as Samsung.
Neither Sony nor Microsoft have released official Australian sales data for their new consoles. Stock shortages have complicated local comparisons.
