Akagi is a mah-jong-centric Japanese comic, written and illustrated by Nobuyuki Fukumoto and first published in 1992. It is featured in the weekly magazine Modern Mahjong, and is a prequel to the author's previous work Ten, in which Akagi's titular character also appears. Due to its popularity, the manga has been adopted into two live-action direct-to-video movies, a 26-episode anime series which aired in Japan in the fall of 2005, and a live-action TV drama series.
