Soji Shimada graduated from Seishikan High School in Fukuyama City, Hiroshima Prefecture, and later Musashino Art University as a Commercial arts design major. After spending years as a dump truck driver, free writer, and musician, he made his debut as a mystery writer in 1981 when The Tokyo Zodiac Murders remained as a finalist in the Edogawa Rampo Prize. His most well-known works include the Detective Mitarai Series and the Detective Yoshiki Series. His works often involve themes such as the death penalty, Nihonjinron, and Japanese and international culture. He is a strong supporter of amateur Honkaku mystery writers. Following the trend of Social School of crime fiction led by Seicho Matsumoto, he was the pioneer of "Shin-Honkaku" logic mystery genre. He bred authors such as Yukito Ayatsuji, Rintaro Norizuki and Shogo Utano, and he led the mystery boom from the late 1980s to present day. As the father of "Shin-Honkaku," Shimada is sometimes referred to as "The Godfather of Shin-Honkaku" or "God of Mystery.” Though a grave critic and writer, Shimada is not the harsh, grim character that many imagine him to be; in fact, he is quite friendly in person. One could get a sense of his character in his humor mysteries such as Soseki and the London Mummy Murders and Let There Be Murder, Any Kind of Murder. These novels, especially the latter, involves an extravagant mystery trick as well as elements of satire, confusion, youth, and. These colorful themes made the novel into a great hit, and were made into a short series. In recent years, he has begun a new challenge—an animated series called the "Taiga Novels," collaborated with the renowned illustrator Masamune Shirow. Upon its kick-off in January 2008, he and Shirow plan to create a twelve-book series through the Kodansha BOX publishers. On top of the BOX, Shimada holds a column in the celebrated magazine, the Weekly Shincho. He is also heading two newly founded Amateur Mystery Novel contests—first, "The City of Roses Fukuyama Mystery Award" for amateur writers in Japan, and the "Soji Shimada Mystery Award" in Taiwan, sponsored by Crown Publishing company. Even past the age of sixty, his passion for writing has become stronger than ever: he is truly the maestro of Shin-Honkaku mystery. In 2019 he joined the curated group of award-winning Japanese authorsRed Circle Authors.
