The latest remake of the Dragon Quest series to hit the Nintendo DS went straight to the top spot this week, hardly surprising in a country which has a law against releasing "Dra-Que" games on a school day.

Wii Fit is showing no signs of slowing down during the hot summer months here in Japan and looks to be challenging Wii Sports for the biggest selling Wii game, not bad considering it costs almost twice as much.

Mario Kart Wii is also proving to have tremendous legs, already passing one and a half million sales.

The sequel to Band Bros. is selling strongly at No.7, a game not seen outside of these shores. Perhaps this will convince Nintendo of America to finally release it outside of Japan?

Bringing up the rear is the latest installment of the Stafi series, another title never released in the West, as well as the ever-present Monster Hunter Portable, of which sales seem to be slowing down after many weeks in the charts.

Portables again seem to be the most popular hardware choice in Japan this week with the PSP leading the pack by almost 20,000 units. If you compare total hardware units from Nintendo's two systems to Sony's three systems, there is only a 500-unit difference in favour of Nintendo. Some may call that a neck and neck race.

Who will come out on top during the summer vacation period of August? Only time will tell.

1. PSP – 74,024
2. DS – 54,531
3. Wii – 40,803
4. PS3 – 11,253
