PlayStation 3 sales nearly doubled week-on-week in Japan to 50,164 for the week ended March 21, according to Media Create. Thanks to the boost, the PS3 was able to outsell regular handheld chart-toppers PlayStation Portable as well as Nintendo's line of DS hardware. The PS3's strong performance occurred the same week as the release of Sega's Japanese organize crime-themed game, Yakuza 4. Media Create reported that the game sold a hefty 384,000 units in its opening week. In addition, this week saw the much-awaited release of the Torne, a device that turns the PS3 into a digital recorder. It is available in Japan as a standalone unit as well as bundled with a PS3. PSP sales, including the PSP-3000 and PSP Go, stood at 39,508 units for the week, enough to capture the second slot. Combined sales of the DS line, which includes the DS Lite, DSi and DSi XL, were close behind at 38,974 units for the week. Below are the full sales rankings from Media Create for the week ended March 21, 2010. (The second chart lumps together sales of all models in a given line of hardware.)
