Title: Kyōko no Ie
Content:   Kyōko no Ie (鏡子の家) ("Kyoko's House") is a 1959 novel by the Japanese writer Yukio Mishima. The book tells the interconnected stories of four young men who represent different facets of the author's personality. His athletic side appears as a boxer, his artistic side as a painter, his narcissistic, performing side as an actor and his secretive, nihilistic side as a businessman who goes through the motions of living a normal life while practicing "absolute contempt for reality". Mishima's biographer and translator, John Nathan, has called Kyōko no Ie "an unsettling, even a terrifying book", at least partly because it seems prophetic in its anticipation of developments in Mishima's own life: the boxer takes up right-wing politics and the actor becomes involved in a sado-masochistic sexual relationship which ends in double suicide for himself and his lover. The story of Osamu, the actor in Kyōko no Ie, was one of three Mishima works adapted by Paul Schrader for his film Mishima: A Life in Four Chapters. Although the novel has not been translated into English, Schrader used it because his original choice, Forbidden Colors, was vetoed by Mishima's widow.
Title: Kyōka Izumi
Content:  Izumi Kyōka (泉 鏡花), real name Kyōtarō Izumi (泉 鏡太郎), was a Japanese author of novels, short stories, and kabuki plays who was active during the prewar period. Kyōka's writing differed greatly from that of the naturalist writers who dominated the literary scene at the time. Many of Kyōka's works are surrealist critiques of society. He is best known for a characteristic brand of Romanticism preferring tales of the supernatural heavily influenced by works of the earlier Edo period in Japanese arts and letters, which he tempered with his own personal vision of aesthetics and art in the modern age. He is also considered one of the supreme stylists in modern Japanese literature, and the difficulty and richness of his prose has been frequently noted by fellow authors and critics. Like Natsume Sōseki and other Japanese authors with pen names, Kyōka is usually known by his pen name rather than his real given name.
