In the show Sato, born in Kyoto, Japan on July 9, 2129, is the communications officer aboard the starship Enterprise (NX-01), and a linguist who can speak more than forty languages (polyglotism),[1] including Klingon.

She is an acknowledged linguistic genius and expert at operating the universal translator, a key instrument in allowing the crew to communicate with alien cultures.

The series' final episode, "These Are the Voyages...", reveals that Sato remains Archer's communications officer throughout his tenure as captain, and was considering resuming her teaching career in Brazil following the ship's decommissioning.

According to a computer bio screen, shown in the episode "In a Mirror, Darkly", and taken from the memory banks of the USS Defiant, Sato was born in Kyoto, Japan.

A portion of her biography created for the episode not seen on-screen, stated that she and her family were among four thousand people who died on Tarsus IV in 2246 when a food shortage caused by an exotic fungus threatened the colony's population.

After Archer used the USS Defiant to put down the rebellion, Sato poisoned him and took command of the ship, taking the Mirror Travis Mayweather as a new consort.
