Toshio Shimao

 was a Japanese novelist. He has been called a "writer's writer", which is used as both a compliment and criticism.
Biography.
Shimao was born in Yokohama, but his family moved to Kobe when he was eight. His mother died when he was seventeen and soon after he had a period of study in Nagasaki. He later traveled to Taiwan and the Philippines, but returned to education and graduated from Kyushu University in 1943. In 1944 he entered the military and was sent to Japan's southern Amami Islands as an officer for a naval suicide attack (kamikaze) squadron in World War II. The war ended while he was still waiting for his orders. His wartime experiences inspired his earliest works, including "Shima no hate" (1946) and "Shutsukotō-ki" (A Tale of Leaving a Lonely Island, 1949), as well as several later works including "Shuppatsu wa tsui ni otozurezu" (1962) and "Gyoraitei gakusei" (Student on the Torpedo Boat, 1985). His wartime period is also where he met his wife, Miho, a Catholic.
A second major theme in his work is that of madness in women, with notable examples in "Ware fukaki fuchi yori" (1954) and "Shi no toge" (The Sting of Death, 1960). This theme was related to his wife's mental illness. At some point in 1955, the date is unclear, his wife became mentally ill to the point of requiring hospitalization. He then chose to live with her at the mental hospital, which was seen as a highly unusual action yet praised by Yutaka Haniya's wife as showing "extraordinarily deep love." Although Shimao seems to have felt somewhat to blame for his wife's illness due to his past affairs and what he describes as his own selfishness. In 1955 he took her back to Amami Ōshima, the largest of the Amami Islands; his novella "The Sting of Death" describes this period using his own name and that of his wife. That work was adapted for the film "The Sting of Death" in 1990.
A possible third aspect is that in 1956 he converted to Catholicism and his interest is said to be present with the title "The Sting of Death" being a reference to 1 Corinthians 15:55.
