PSP leads 3DS again in Japan

After only one week of trailing the 3DS the PSP is once again the best-selling hardware platform in Japan, as Nintendo DS titles take the number one and two spots in the software charts.

The PSP has been the only major format affected by supply problems since the Japanese earthquake disaster, with website Andriasang suggesting that the system is still selling out quickly as new stock arrives.

As a result this week sales more than doubled to 49,427 - including 265 sales for the PSPgo. The 3DS though continued its slow decent, shedding another 5,000 unit sales for a total of 23,038.

The PlayStation 3 also saw a drop in sales, of around 3,000 units, to 22,265. Combined sales for the Nintendo DS family of consoles stood at 13,561, while the Wii slipped a few hundred to 7,866.

The top-selling software title of the week was DS hardware bundle Battle & Get! Pokémon Typing DS, which comes packaged with a full QWERTY keyboard. The game includes a number of Pokémon themed mini-games aimed at teaching typing skills - a surprisingly common spin-off concept in Japan that has previous encompassed franchises such as Street Fighter and The House of the Dead.

Battle & Get! sold 59,363 units on its debut, below the 100,000 minimum usually expected for a number one title in Japan - although the higher unit price will have compensated for this to a degree.

The second-highest new entry of the week was a new DS tie-in to anime Detective Conan at number six, with the Namco Bandai title selling 19,786 units over the course of the week.

Spike's new action title GachiTora! Sold 13,560 units at number seven, while Zipper Interactive's SOCOM 4 (aka SOCOM: Special Forces) debuted at number eight with 12,613 units sold. This is a much higher initial chart position than the game earned in its recent UK release.

Rounding out the charts is hardcore 2D shooter Otomedius Excellent from Konami on the Xbox 360, with 10,502 units sold.
