Tomonobu Itagaki(板垣 伴信,Itagaki Tomonobu?) is a Japanesevideo game designer best known for creating the Dead or Alive series and also reviving the Ninja Gaiden franchise in 2004. Joining Tecmo in 1992, Itagaki produced two video game franchises that were commercial successes and earned him several promotions; he headed Tecmo's development team, Team Ninja, and sat on the executive board. He left the company after 16 years of service, filing a lawsuit against it for withholding bonus pay. His new team at Valhalla Game Studios, comprising other Team Ninja members, is currently working on a new game, Devil's Third.
Born in 1967, Tomonobu Itagaki graduated from Waseda University Senior High School on March 1985. Following that, he entered Waseda University and graduated from its School of Law on March 1992.
He is married, and has a daughter, born in 1997, whom he has mentioned as one of the primary influences on his projects, including developing Ninja Gaiden: Dragon Sword for the Nintendo DS, and a constant gaming partner in games like the Halo series. Itagaki has in his office a set of katana his father made for him, which he tends to take out to show to his visitors. As he wishes to stop people from reading his expressions during gambling-type games, he is always seen wearing sunglasses, a habit that has become his trademark in the video game community.
