History

Sato first appeared in the Doctor Who episode Aliens of London (2005), where she was called in to examine a supposed alien corpse at Albion Hospital. On Torchwood, Sato is the Cardiff branch's technical expert (described as a "computer genius"). She does however operate as a medical doctor still - in Small Worlds she arrives at a police station to determine a man's cause of death.

It is revealed in Greeks Bearing Gifts that Sato's parents were both in the Royal Air Force, and her grandfather worked at Bletchley Park, the World War II code-breaking facility. Sato joined a government scientific think-tank after graduating from university, and was recruited by the Torchwood Institute to work with Jack Harkness three years before the series begins, suggesting she was infiltrating Albion Hospital on its behalf. Teammate Gwen Cooper believes she is of Japanese descent, describing her as a "Japanese woman"[3], although it is established in Greeks Bearing Gifts that she herself was born in the UK in July 1975 and her family returned to Osaka when she was two, before returning to the UK in 1986. A letter on the Torchwood Institute website implies that she has some family members who cannot read English.
