Game sales continue to slump in Japan

The Japanese games market finally has a new number one, although sales for both software and hardware remain in the doldrums.

Acquire's self-published Akiba's Trip involves defeating vampire-like creatures by ripping off their clothes and exposing their body parts to sunlight. Set in Akihabara's busy shopping district the PSP game seems unlikely to enjoy a Western release and sold only 58,150 units to get to number one.

Tecmo's Dead or Alive Dimensions is the highest-charting 3DS game since the system's launch, but it sold only a meagre 23,078 units at number two.

Strategy game Gungnir at number four sold just 16,355 units and while Valve's Portal 2 on PlayStation 3 is a surprise entry at number six it registered only 8,942 unit sales.

The lowest ranked title in the top 10, 3DS title Steel Diver, sold only 4,583 units to ensure its appearance in the chart.

Hardware sales, obtained by website Andriasang, were similarly unimpressive, although the now familiar hierarchy was undisturbed as most formats saw sales decrease by a similar proportion.

The PSP led with 30,463 unit sales, followed by the 3DS on 17,240. The PlayStation 3 was down to 12,935, while the Wii was almost unchanged at 6,269.
