Overworks was a SEGA-owned development studio headed by Noriyoshi Ōba. The studio's roots can be traced back as far as Sega Development Division 6 in 1988, but would take on its most recognizable form by 1993 with the establishment of Sega CS2 R&D Division. Under Ōba's direction, the studio left its mark on the industry with such franchises as Streets of Rage, Shinobi, Sakura Taisen, and Skies of Arcadia.

The distinction between arcade (AM) and consumer (CS) divisions was abandoned by 1998, and the studio became known as Sega AM7 R&D Division during this period. Along with each of Sega's other development divisions, AM7 was spun off as an independent studio on April 21, 2000, taking the name Overworks. The name was given two interpretations: the studio's goal was exceed (or "go over") players' expectations, and "Ōba's Works".

Overworks was merged into Wow Entertainment in October 2003, creating SEGA WOW. Ōba left Sega shortly thereafter, subsequently holding senior and board positions at Interchannel, GungHo Works, and most recently Premium Agency.
