Nintendo’s DSi returns to more familiar territory this week as the handheld once again climbs to the top of the Japanese hardware sales charts.

According to data provided by Media Create, the DSi sold 71,233 units; up over 40,000 units from last week’s figures. The jump in sales were in line with the successful release of Super Robot Taisen K, a DS title which had broken over 100,000 units sales in a single week.

The PSP, on the other hand, was still enjoying weekly gains, climbing over 20,000 units to reach a figure of 65,765.

Sony’s PS3 fared well too, despite a sales trim. The system sold just over 25,000 units, a rate that remained far ahead of Nintendo’s Wii, which continues to dwell around the 18,000 mark.

The Xbox 360’s momentum has mostly disappeared; sales during the first full week of March were at 15,000, in line with the release of Resident Evil 5. Yet a week later the system was hit by the heaviest drop in unit sales amongst its peers; down from 15,000 to 8,378.

This week 360 sales have dropped further, down now to 5,441 units; a mere few hundred above Sony’s Playstation 2, which itself has hovered at the five thousand mark for months irrespective of market fluctuations.
