Yuji Naka — Japanese Programmer, Designer and Creator Associated with Sonic Team

Contributions and signature work

Naka is best known as the former head of Sonic Team, where he served as lead programmer for the original Sonic the Hedgehog series. Working on the Sega Genesis platform, he helped create a fast-paced platforming experience that contrasted with contemporaneous games through tighter physics, level design tuned to velocity, and technical tricks to produce smooth scrolling and animation on limited hardware.

Career development

After rising through roles at Sega, Naka left to form his own independent studio, Prope, in 2006 to pursue smaller and more experimental projects. Later he returned to the larger industry for a period: in January 2018 he accepted a position with Square Enix. Throughout his career he has combined hands-on programming with wider design and production responsibilities.
