Sony Computer Entertainment has announced that worldwide PS4 sales reached six million units as of March 2.
The console launched in North America on November 15, 2013, in Europe two weeks later, and in Sony's home nation on February 22. It is currently available in 57 countries worldwide.
Sony opted to delay the PS4 release in Japan to ensure it didn't give Microsoft's Xbox One a head start in the next-gen race in key western territories, while providing studios with time to develop PS4 software specifially catered to the domestic market.
The company said on Tuesday that Japanese PS4 sales stand at 370,000 units. The system sold as many as 320,000 units in its launch weekend, ensuring pack-in game Knack topped the weekly software chart.
"I am absolutely delighted that PS4 is off to such a great start in Japan," said Sony Computer Entertainment Andrew House.
"The responses we have received for the PS4 system's integrated social capabilities have been phenomenal, and I couldn't be more thrilled that gamers are utilizing these unique features to engage, share, play and connect with users around the world."
According to Sony, more than 100 million shares have been captured via the 'Share' button on the PS4 controller, while over 3.6 million gameplay broadcasts have been streamed from PS4 systems via Twitch and Ustream.
House said "SCE will continue to expand the world of PlayStation by growing its library of breakthrough games and bringing more innovative features and services only possible on PS4."
Last month, Sony said worldwide PS4 sales stood at 5.3 million units as of February 8, while Microsoft said in January that global Xbox One sales topped three million units between the console's November 22 launch and the end of 2013.
