In 1989, Square established SquareSoft in Redmond, Washington, to provide development and publishing support in the West. As Square moved its projects to PlayStation in 1994, SquareSoft moved to Marina del Rey, California, while changing its name twice in one year, to Square LA followed by Square USA.

In 1997, a second Square USA branch was opened in Honolulu, Hawaii to focus on new interactive entertainment research, going on to help with CGI development, this studio would become primary on developing Parasite Eve and Final Fantasy IX.

Square USA's Hawaiian branch developed the CGI short "Final Flight of the Osiris" that later formed part of the 2003 anthology film The Animatrix. The branch was shut down in March 31st, 2002 following a failed attempt to find a film studio partner.
