Masahiro Ito was born in Saitama, Japan in 1972 and later graduated from the graphic design department of Tama Art University.
In 1997 he joined Konami to design the backgrounds and creatures in Silent Hill. His disturbing creations continued in Silent Hill 2 in which he was art director in addition to creating all of the creature designs, models and motions. It was in this game that Ito designed his most popular creation - Pyramid Head.
His last major input at the company was in Silent Hill 3 where he reprised his role as art director as well as the creature design, models and motion in addition to again designing and modelling the backgrounds.
While being credited in the special thanks of Silent Hill 4: The Room and contributing cover art for Silent Hill: Origins, Silent Hill: Homecoming and Silent Hill: Downpour, Ito has not had any major involvement in the franchise since Silent Hill 3.
