Anime isn't exactly a small thing in Japan, so it's no surprise that this week's Media Create chart leader is based on one of the most popular animated series in the country. Namco Bandai's four-player brawler One Piece: Gigant Battle for the DS topped the Japanese stat-tracking firm's sales chart for September 6-12, selling 131,854 copies during its first few days of availability.

　　Monkey D. Luffy was always a high flier. One Piece's six-figure debut was the only impressive start for games this week. The next two best-selling newcomers--D3 Publisher's VitaminX Evolution Plus and Irem's Sengoku Efuda Yuugi: Hototogisu Tairan--managed eighth- and 10th-place finishes, selling 7,975 units and 7,407 units, respectively.

　　As for the remainder of the chart, Capcom's highly popular Monster Hunter franchise proved its lasting power, as MonHun Nikki: Poka Poka Ailu Mura for the PSP scored a second-place finish with 55,569 units sold. Nintendo and Namco Bandai secured the remainder of the top five, as Wii Party held a considerable lead over Ace Combat: Joint Assault, and Metroid: Other M sold just 11,239 units during its second week.

　　The hardware chart offered little in the way of noteworthy performances, as the PSP assumed its usual pole position with 30,761 units sold. The PlayStation 3 followed with 19,907 units sold, with a Nintendo triple play of the DSi LL, DSi, and Wii falling in at third, fourth, and fifth. The DS Lite, Xbox 360, PlayStation 2, and PSP Go all sold less than 5,000 units.
