The 77th volume of Eiichiro Oda's One Piece shipped today in Japan with a first printing of 3.8 million copies, marking the first time in four years the manga has slipped below 4 million.
While American comics companies would be breaking out the champagne bottles with numbers like that, Anime News Network reports One Piece publisher Shueisha released a statement clarifying that, "Aside from print publications, [Shueisha] also distributes its comics digitally, and our sales channels are increasing." A digital edition of Vol. 77 will be released next month.
The bestselling manga in the world, One Piece first reached the 4 million-copy mark in November 2011 with Vol. 64, setting a record in Japan. The series reached a peak in August 2012 with 4.05 million copies.
Debuting in 1997, as of last year Oda's fantasy adventure had sold more than 310 million copies in Japan alone. Despite the growing popularity of Attack on Titan, One Piece clung to the top spot last year, selling 11.9 million copies.
