Japan Charts: Second week at the top for Koei's Dynasty Warriors 5

Koei has held onto pole position in the Japanese leisure software charts for a second week running with the latest instalment in the Dynasty Warriors franchise, but the market as a whole has slumped to its lowest point in the year to date.

Total sales for the top 100 titles dropped below 600,000 units for the first time since the beginning of the year, despite the launch of a number of new titles - with seven of them in the top ten, but none managing to break the 50,000 unit mark.

In fact, Dynasty Warriors 5 was the only title to sell more than 50k units last week, with the next best seller being another Koei title, new release Romance of the Three Kingdoms X, which sold 31,000 units.

The PSP re-release of popular RPG Tales of Eternia continues to sell quite well, dropping just a single place in the chart to become this week's number three, but it's the only PSP title in the top ten - with the DS managing two, as new releases Pac-Pix and Meteos come in at number four and six respectively.

The rest of the new releases are a mixed bunch, with Nintendo's GBA title Sennen Kazoku at number five, Bandai's Dragon Ball Z 3 at number seven, Konami's Ys: The Ark of Napishtim at number eight, and Capcom's Mega Man X8 propping up the chart at number ten.

In hardware terms, the PSP continues to lead the field with nearly 35 per cent market share, trailed by the PS2 with 31 per cent share and the Nintendo DS with 20 per cent. The GBA has also rallied slightly, with over 11 per cent market share this week, but the Cube continues to languish on just over three per cent.

The market share gap between the PSP and the Nintendo DS looks more impressive than it actually is, however. The DS still has enough of a head-start in terms of unit sales that it will continue to be the bigger-selling platform in Japan right through to the end of the year if current weekly sales figures are maintained.
