Sega CS1

Sega Consumer Research and Development Dept. #1 (Sega CS1) was a video game research and development division within Sega. As the name suggests, it was the first "consumer"-specific R&D department created by Sega of Japan. It was officially founded in April 1996 and headed by Makoto Oshitani.

In May 1999, all of Sega's internal development divisions were renamed, with CS1 becoming Sega Software R&D Dept. 6
