Nihon Image Works was established in Tokyo on August 1, 1991 by Keiichi Onogi, formerly a producer at NCS. The studio was well known for its life-simulation games, particularly the Graduation and Debut series. Teruyuki Teshima, previously a programmer at BEC, was the company president after 2000. It was initially just a production and licensing company; it merged with the PC game production team Head Room in March 1992, and a development office was opened in Shibuya in August 1994. The company name was changed to Image Works Co., Ltd. in April 1995. It appears to have closed down around 2004.
