Kyoji Kobayashi (born 1957) is a Japanese novelist. Born in Hyogo Prefecture, he studied aesthetics and art at the University of Tokyo, where he was also a member of the university's haiku club. He made his literary debut after receiving the Kaien New Writers Award in 1984 for "Denwa Otoko." His fiction incorporates elements of history, science fiction, and metafiction, while he has also written extensively on haiku, tanka, and kabuki. He is currently Professor in the Faculty of Letters at Senshu University. His novel "Kabuki no Hi" received the 11th Mishima Yukio Prize. Set in the vast theater known as Sekai-za, the novel intertwines the forms and rituals of kabuki with fiction and reality, unfolding as if the entire work itself were an elaborate kabuki performance.
