Ryu Ga Gotoku Studio

is a Japanese VIDEO game development studio owned by Sega. Ryu Ga Gotoku Studio is a part of Sega CS Research and Development No. 1

Since Yakuza 3, they have been referred to as SEGA's CS1 team, all the way up to Yakuza: Dead Souls. The very first video game to use the studio's original logo was Binary Domain in Japan, released in February 2012. Eventually, the RGG Studio's logo became used consistently as the way they brand themselves and give themselves an identity of their own.
