The market survey firm Oricon reports that the 63rd volume of Eiichiro Oda's One Piece pirate manga sold 2,119,400 copies between its first official day of sales (August 4) and August 7. It sold more copies in one week than any manga has since Oricon began reporting its book ranking charts in April of 2008.
Not only did the latest One Piece volume topped the weekly manga ranking chart, but it is the third One Piece volume to sell over over 2 million copies in one week. (Volumes 60 and 61 were the first two volume to sell over 2 million in one week, but volume 62 did not, in part due to the March 11 Great Eastern Japan Earthquake disaster and people buying before the first official day of sales.) It also beat the series record for weekly sales, which volume 60 had held by selling 2,094,123 copies in its first week last November.
Volume 63 already holds a manga record for having 3.9 million copies published in its first print run.
