Masahiro Sakurai (桜井政博, born August 3, 1970) is a video game designer. He is credited for the creations and development of the Kirby series and the Super Smash Bros. games.
Sakurai was once an employee of HAL Laboratory, Inc., a second-party video game developer for Nintendo. It was here at HAL where he being 19, created Kirby. He would also develop Super Smash Bros. and its sequel. Sakurai resigned from HAL on August 5, 2003 mostly out of belief that both video game industry and gamers believed in a sequel to every game HAL released. Many fans were in despair, believing that the Kirby and Super Smash Bros. series would cease development.
After his resignation from HAL, he worked at Q Entertainment, another game developer and designer. Sakurai announced formation of his own company, Sora Ltd. Along with other companies, they produced the highly-anticipated Super Smash Bros. Brawl, the third game to the Super Smash Bros. games. Currently, Sakurai began a first-party studio, Project Sora, which is owned by Nintendo and Sora Ltd.
