Kaneko Seisakusho (金子製作所), also referred to as Kaneko Co. Ltd. (カネコ株式会社), was a Japanese video game publisher founded in Suginami, Tokyo, Japan by Hiroshi Kaneko. It published a number of games both under its brand and other companies, such as Air Buster, Nexzr, Shogun Warriors, DJ Boy, Guts'n, and the Gals Panic series. Although most of the games that Kaneko produced were standard arcade fare, they also earned a degree of notoriety for both DJ Boy (for its reputedly racist plot and negative stereotyping) and the Gals Panic series (the games often bordering on softcore pornography).
The last game released by the company was Gals Panic S3 for the Arcade in 2002.
