Project Itoh (伊藤 計劃 Itō Keikaku?), real name Satoshi Itō (伊藤 聡 Itō Satoshi?, October 14, 1974 – March 20, 2009), was a Japanese science fiction writer. Born in Tokyo and graduated Musashino Art University. While working as a web designer, he wrote Gyakusatsu kikan and submitted to Komatsu Sakyō Award contest in 2006. Although it did not receive the award, it was published from Hayakawa Publishing in 2007 and was shortlisted to Nihon SF Taisho Award. A poll by the yearly SF guidebook SF ga yomitai ranked Gyakusatsu kikan as the number one of the domestic SF novel of the decade. Since 2001, he had to be hospitalized time to time for recurrent cancer. He died at age 34 on March 20, 2009. The video game Metal Gear Solid: Peace Walker was dedicated to his memory.

武藏野美術大學映像科畢業。 2007年以橫掃日本科幻小說界的《虐殺器官》出道，迅速成為日本21世紀科幻小說界的明日之星。遺憾的是，他於2009年因為肺癌去世，只留下《虐殺器官》與《和諧》兩部原創長篇小說與一部電玩「MGS」系列的小說化作品《METAL GEAR SOLID GUNS OF THE PATRIOTS》以及短篇集《The Indifference Engine》。 《屍者的帝國》的序章是他的遺稿，刊登於2009年7月號的《SF MAGAZINE》。去世後，以《和諧》英譯版獲得2010年菲利普‧K‧迪克獎（Philip K. Dick Award）特別獎。
