It was founded in October 1990 by Hiroshi Hamagaki and Tomo Kimura, who left Sega to form the company.

On the other end, there was Kileak: The DNA Imperative, a first-person mecha shooting game for the PlayStation which was released in 1995 and received a sequel, Epidemic.

Genki found its niche in 1994 with the release of Shutokō Battle '94 Keichii Tsuchiya Drift King for the SNES—the first in a long-running series of racing games.

Within the same year, Genki shifted towards developing 3D games, continuing the Shutokou Battle series with Highway 2000 (released in Japan as Wangan Dead Heat) on the Sega Saturn.

In 2002, Namco partnered with Genki to produce a game based on Michiharu Kusunoki's racing manga, Wangan Midnight.

Namco partnered with Sega to continue its arcade game series with the release of Wangan Midnight Maximum Tune in 2004 that shifted away from the Shutokou Battle style.

It is still developed today and receives regular updates across Japan, Asia, Oceania, China, and North America remaining exclusive to arcades with Genki still featuring in its credits.

The GRP's first title was Shutokou Battle Online for Microsoft Windows, which tried to apply an MMO-like aspect to the existing gameplay of the series.

However, on July 22, 2016, Genki announced that the Project would be rebooted, hoping to have new Shoutoku and/or Kaido Battle games for the next generation.

Kengo (剣豪) is the name of a series of fighting video games developed by Genki.

The Shutokou Battle series was revived with a Mobage version for mobile phones released on January 27, 2017.
