Tetsuya Mizuguchi (Japanese: 水口哲也, Mizuguchi Tetsuya, born May 22, 1965 in Otaru, Hokkaidō, Japan) is a video game designer and founder of the video game development firm Q Entertainment.
Mizuguchi worked for Sega from 1990-2003 and was behind titles as Sega Rally Championship, Space Channel 5 and Rez. His last position was Chief Creative Officer of Sega's United Game Artists game division.
On September 2003, Sega performed an internal restructuring of its staff. Among these changes was the dissolution of United Game Artists and the transfer of its members into Sonic Team. The following month, Mizuguchi announced that he would leave Sega on October 10, 2003. He cited the changes in the corporate culture after the Sega-Sammy merger, and viewed that as an obstacle to what he wanted to do. He announced that he would freelance for the video game industry through an at the time unnamed company.
He has since founded Q Entertainment and initially produced two puzzle games for portable systems: Lumines for the PlayStation Portable and Meteos for the Nintendo DS. Both games have been released in Japan, North America and Europe. With Q Entertainment, he later produced Lumines Live! which was released for the Xbox 360 through Microsoft's Xbox Live Arcade service on October 18, 2006. November 7, 2006 he also produced for the PSP, Lumines II, the sequel to the popular original, and a shooter/puzzle game called Every Extend Extra which was released on August 7, 2006, based on the small project by "Omega" called Every Extend.
Also, Mizuguchi worked on Ninety-Nine Nights as an external contractor and is the main producer for the Quest Beat label. He regularly flew back and forth between Japan and South Korea to work at Ninety-Nine Nights developer Phantagram.
Most recently, he oversaw the development of Gunpey, a title with versions for both the Nintendo DS and PlayStation Portable, in honor of Gunpei Yokoi. And a new version of Every Extend Extra was produced for Xbox Live called Every Extend Extra Extreme, which was released on October 17, 2007.
