Rutubo Games was established in 1994 by Masatoshi Hashimoto. Rutubo Game Works Co., Ltd. is a recent offshoot company, founded in 2010 to focus on games production while its predecessor switched to IT services. Like its precursor, Rutubo Game Works consists of talented programmers such as including Shinichiro Mukaigashira, Tetsu Matsushima, and Takeshi Maeda; several of the staff had previously worked at Dempa Shimbunsha. while the systems infrastructure work appears to still be done by Rutubo Games. The company was best known for their high-quality ports of arcade titles to home computers and consoles, but more recently has provided programming and online infrastructure support for arcade titles. Hashimoto and Mukaigashira left sometime before 2005 to start Gotch Technology; Matsushima heads the company today.
