His first novel, the psycho-thriller Saimin (Hypnosis) sold over a million copies on its release in 1997 and has been adapted into a film of the same name by Masayuki Ochiai. His sophomore release of Senrigan (Clairovoyance) about a Air Self-Defense Force fighter pilot turned clinical psychologist launched a popular series, which have achieved combined sales of over six and a quarter million books. He is author of the nine-volume Banno kanteishi Q no jikenbo (Casebook of Universal Appraiser Q) series, and the Tantei no tantei (Detective vs Detectives) series, also adapted into a television series of the same name by Fuji TV.
