Nobuyuki Fukumoto (born 1958) is a Japanese manga artist from Kanagawa Prefecture. He made his debut in 1980 with "Yoroshiku Junjō Taishō" and has built his career around characters trapped by debt, gambling, and coercive organizations. His representative work, "Gambling Apocalypse: Kaiji," follows Kaiji Ito, who becomes liable for a friend’s unpaid loan and enters life-threatening games arranged by a finance company in an attempt to clear the resulting debt. Fukumoto turns simple contests such as restricted rock-paper-scissors into studies of unequal information, group psychology, betrayal, and exploitation, tracing how fear and greed distort judgment and how Kaiji searches for a way to reverse seemingly hopeless situations. The manga received the 22nd Kodansha Manga Award and was adapted into television anime and live-action films.
