Biography
Riichiro Inagaki is a Japanese manga writer from Tokyo, born June 20, 1976. He launched his career in 2001 with one-shots in Shogakukan's Big Comic Spirits before transitioning to Shueisha's Weekly Shōnen Jump, the flagship shōnen magazine. His breakout came when he partnered with artist Yusuke Murata on Eyeshield 21, a football-action series serialized between July 2002 and June 2009 that became his signature work. After Eyeshield 21 concluded, Inagaki spent five years collaborating with multiple artists—Bonjae, Katsunori Matsui, and Ryoichi Ikegami—publishing standalone stories across different magazines. In 2017, he began Dr. Stone with artist Boichi in Weekly Shōnen Jump, a science-adventure series that extended his reach into the 2020s. Inagaki is a screenwriter by trade, working across serialization formats and long-form narrative arcs. Born under Gemini, his career reflects the sign's hallmark intellectual curiosity and cross-genre range. He has three children with Orie Kimoto.
