It's already rare for Japanese manga masters to have one hit series. Recently, an unofficial list sparked discussion, focusing on authors who have continuously produced multiple bestselling manga. The original post claimed that Naoki Urasawa has five manga series with sales exceeding 10 million copies each, making him the author with the most titles on the list.
According to the original post, there are about 30 authors with two manga series that have each sold over 10 million copies; Takeshi Obata, Kenichi Hagiwara, Tsukasa Hojo, Tetsuo Hara, Takehiko Inoue, and Hiromu Arakawa each have three, while Mitsuru Adachi, Rumiko Takahashi, and CLAMP each have four.
Subsequent additions mentioned that Fujiko Fujio A and Fujiko F. Fujio also seem to have three works each exceeding 10 million copies. However, older works have undergone various edition changes, and complete sales data for some veteran authors may not be publicly available, making accurate statistics difficult.
In the discussion, some users cited Yoshihiro Togashi, Akira Toriyama, and Eiichiro Oda, arguing that the massive influence of a single work does not necessarily mean an author has three titles in the 10-million-plus club. Others pointed out that Fumiya Hosono's wide range of creative themes makes it inappropriate to judge him solely by sales figures in a single category.
This list does not provide a unified scope of statistics, specific titles, sales milestones, or publisher data. Therefore, the figure of "about 30 people" and the number of works attributed to each author remain to be verified and should not be considered an official industry ranking.
