Nintendo wrestled dominance of the Japanese hardware market back from Sony this week, launching its new DSi LL to enviable success.
Regional data collector Media Create counted 100,553 sales on 22nd November - one day after the handheld's launch. That's more than Sony's PSPgo has sold in Japan (54,102) since it went on sale on 1st November.
Add DSi (32,070) and DS Lite (5051) sales and Nintendo's handheld posted a region-leading total of 137,674. The PSP (32,752) and PSPgo (4574) combined to sell 37,326 units.
The PS3 (34,752) was still ahead of the Wii (32,844), and the Xbox 360 (4085) and PS2 (2024) were still miles behind everything else.
Interestingly, Valve's infectious tour-de-force Left 4 Dead 2 managed a Japanese software debut in sixth, which is pretty impressive considering what it's up against.
Other newcomers this week were Taiko Drum Master Wii 2 (5th), Mario & Sonic at the Olympic Winter Games (9th) and Ratchet & Clank Future: A Crack in Time (14th).
The week's top-selling game was Pokémon Heart Gold/Soul Silver on DS (55,361), which climbed over the three million lifetime sales mark in the process.
Best-sellers Tomodachi Collection (2nd) Wii Fit Plus (3rd), Inazuma Eleven 2 (4th), PES 2010 (7th), J-League Pro Soccer Club o Tsukurou! 6: Pride of J (8th) and Dragon Ball: Raging Blast (10th) rounded out the top 10.
