Ryu ga Gotoku Studio (龍が如くスタジオ) is a studio within Sega CS1 responsible for more recent Yakuza games. It was spun off from CS1 after the development of Yakuza: Dead Souls was completed. According to Masayoshi Yokoyama, one of the leads of the studio, the studio is not a company organization but rather a "concept" or a "production team", much like Sonic Team. For non-Yakuza game it has been used for Binary Domain in Japan.
