"It would be a great loss to Starfleet if you were not a part of this crew. If you feel I've been unfair to you, I apologize, but I hold you to a high standard, Ensign, because I know you're capable of achieving it."
– T'Pol, 2151 ("Vox Sola")

Hoshi Sato was a noted Human linguist stationed aboard the United Earth starship Enterprise NX-01 during its historic mission of exploration. Beginning in 2151, Sato served as the ship's translator, protocol officer, and communications officer, and she was eventually responsible for the creation of the linguacode universal linguistics matrix in the following decade.

Childhood and youth[]

Born in Kyoto, Japan on July 9, 2129, the second of three children, Hoshi Sato showed from an early age that she was gifted. (ENT: "In a Mirror, Darkly, Part II" display graphic, "Exile") Most of her childhood was spent with private tutors, learning languages. Sato did not have the opportunity to become very close to anyone. To her, it was often normal to spend an entire day virtually alone. This feeling of isolation stayed with Sato throughout her life; even as an adult surrounded by other people, Sato still felt alone. The reason she studied languages was to try to make connections to other people and cultures. The last person Sato was really close to was her grandfather, Michio Sato. (ENT: "Exile") When she was twelve years old, Sato had a pen pal from Brisbane, Australia. She loved receiving letters from her pen pal, later noting, "It was like this little window into distant places with strange-sounding names." (ENT: "Dear Doctor")

When Sato was young, she often claimed her stomach was slightly unsettled as an excuse not to eat her grandmother's soba noodles, which she disliked. Eventually, though, it became one of her favorite foods. (ENT: "Exile") Sato was never called to the principal's office. (ENT: "The Council") Her mother wanted her to become a pianist, but Sato chose a scientific career instead. (ENT: "Damage") She also had a black belt in Aikido. (ENT: "Observer Effect")


Early years[]

After mastering a number of Earth languages, Spanish, French and German among them, Sato went to school to become an exo-linguist. She graduated second in her class and went on to spend three years at Starfleet Training Command. She had two training tours and had, both times, portside quarters. In her second month, Sato was discharged for breaking her company commander's arm after a dispute about a weekend poker game she organized for new recruits. Starfleet allowed her back in on probation, since they needed language experts. By the end of her training, she had been cleared for EM sidearms and Class 3 pulse rifles. (ENT: "Fight or Flight", "Observer Effect")

According to dialogue in the first draft script of "The Andorian Incident" (which had the working title "Incident at P'Jem"), Sato attended Starfleet Ranger School, in Atlanta, and was granted her clearance for Class 3 pulse rifles there.

Hoshi Sato as teacher

Sato, while teaching languages in Brazil in 2151

While a university professor in Brazil, Sato and two colleagues took a hydro-skimmer to see the wildlife around the Amazon River but she was terrified by it. (ENT: "Fight or Flight") She taught languages at Amazon University but took a commission aboard Enterprise as communications officer in order to have the chance to experience new languages from outer space. She was initially reluctant to leave her position, but was convinced by Jonathan Archer to end her leave from Starfleet and join the mission. Archer tempted Sato with the realization that she would encounter numerous species and have the opportunity to discover many new languages. (ENT: "Broken Bow")

On board Enterprise[]

The reason Archer chose Sato to be part of the crew on Enterprise was due to her superior language skills. Sato was the first Human to become fluent in Klingonese, which she learned from a linguistic database provided by the Vulcans. Her skill in translating Klingonese came in handy during Enterprise's first mission in returning the Klingon warrior Klaang to Qo'noS and preventing the Suliban from starting a civil war. When Klaang regained consciousness aboard Enterprise en route to Qo'noS, Sato was able to obtain information that helped the mission. She also convinced Klaang that he was not among enemies, and was able to facilitate enough communication between the Klingons and Archer to allow them to visit Qo'noS and return Klaang. (ENT: "Broken Bow")

Hoshi's quarters aboard Enterprise were initially located on E-Deck, starboard section five. At her request, she was relocated, in a swap with Ensign Porter. (ENT: "Fight or Flight") Thereafter, her quarters were on C-Deck. (ENT: "Shockwave, Part II")

In the final draft script of "Fight or Flight" (dated 1 May 2001), the quarters Sato was first assigned on Enterprise were actually on C-Deck. In a revised final draft of the teleplay (dated 27 June 2001), however, those temporary quarters were instead referred to as being on E-Deck.

Shortly after the beginning of the ship's mission, Sato demanded a transfer off the ship after a harrowing experience aboard an Axanar vessel: discovering the crew had been killed and drained of their fluids. Her fear of that almost overwhelmed her, and she believed that she wasn't cut out for deep space exploration. Sato was able to overcome her fears and re-board the ship to decipher the controls to send out a distress call to the victims' fellow beings. When they arrived, they began to fire on Enterprise. Sato broke the language barrier and communicated that Humans were not responsible for the slaughter of the Axanar. The two ships cooperated in destroying the aliens who had caused the massacre. Sato's linguistic abilities had established favorable relations with another new race, and she had been strengthened by the experience. (ENT: "Fight or Flight")

Owing to Hoshi Sato's shocked reaction to seeing alien corpses in "Fight or Flight", Brannon Braga once referred to Sato as "the first [...] character on Star Trek [to] scream in terror." He also believed her response showed her as being markedly different from more futuristic characters such as Harry Kim, of whom he predicted, "Ensign Kim would have just looked at them and said, 'Captain?'" (Star Trek: The Magazine Volume 2, Issue 9, p. 19)

Sato was uncomfortable with the use of the transporter. To Malcolm Reed's comment that the transporter console won't bite, she just remarked, "No, it'll just scramble your molecules." (ENT: "The Andorian Incident")

According to Mike and Denise Okuda, Sato echoes Leonard McCoy who also hated his molecules scrambled. ("The Andorian Incident", text commentary, ENT Season 1 DVD special feature)

Paint brush used on Sato

Sato disguised as an Akaali for a covert mission

Sato was part of an away team to the Akaali homeworld which discovered that the Malurians were secretly mining on a pre-industrial planet and poisoning its water supply. (ENT: "Civilization")

Sato's knowledge of Vulcan proved invaluable. When an away team led by T'Pol became infected by plant life on a planet, making them paranoid and dangerous to each other, she was able to tell T'Pol in Vulcan that an antidote was on its way. Sato was able to decrypt Vulcan messages that T'Pol was receiving, but left Commander Tucker with the language database so he could translate it himself, as she felt uncomfortable with possibly reading private information. (ENT: "Strange New World", "Breaking the Ice")

Sato was in charge of monitoring other vital systems besides communications. When the Suliban Silik had infiltrated Enterprise disguised as a religious pilgrim, she discovered that he attempted to bypass the lockout codes in Shuttlepod Launch Bay One. (ENT: "Cold Front")

Sato was given the task of finding out what Malcolm Reed's favorite food was for his birthday party. She was eventually able to learn that it was pineapple. (ENT: "Silent Enemy")

Sato accompanied Archer to a planet where they found Eska hunters engaging in hunting sentient beings, and she helped protect the beings. (ENT: "Rogue Planet")

Sato assisted Dr. Phlox in attempting to find a cure for the disease killing the Valakians. (ENT: "Dear Doctor")

Later that year, Sato, T'Pol, and Reed became stranded on a disabled Klingon ship sinking into a gas giant. The ship was too low for Enterprise to rescue them. Sato deciphered the ship's logs, controls, and readouts so that they could get the ship running under its own power. She suggested that they fire the ship's weapons to move them to a higher orbit. This worked, and Enterprise was able to rescue them. (ENT: "Sleeping Dogs")

The crew of Enterprise was attacked by an organism that was trying to assimilate the nervous systems of the people it entangled in its tentacles. All attempts to free them failed. Sato, using her language skills, was able to communicate with the entity, who released the crew members in return for being transported back to its home planet. (ENT: "Vox Sola")

By 2152, Sato spoke and understood between thirty-eight and forty languages. (ENT: "Two Days and Two Nights")



During shore leave on Risa, Sato met an alien named Ravis, with whom she had a romantic affair. She also spoke Risian, which impressed the local people. (ENT: "Two Days and Two Nights")

When Enterprise was called back for destroying a colony, they found evidence that the Cabal was to blame. They were captured by the Cabal on orders to bring Archer to their master. Though the crew was confined to their quarters, they were able to communicate with their room comm systems. The only escape was through the air vents, which were too tight for everyone to squeeze through except Sato. She made her way to Phlox's room, to retrieve a pair of needles, before moving on to Reed's room. Just as she arrived, her shirt caught on a hook, and was torn off, leaving her to answer Reed's door with her hands over her chest. They were barely able to escape from the Suliban. (ENT: "Shockwave", "Shockwave, Part II")

In 2152, Sato helped teach a mining colony to defend itself against Klingons. She later was injured by a Romulan minefield in 2152. (ENT: "Marauders", "Minefield")

Sato helped translate for the Kreetassans, who were a race very easily offended. She not only translated the language, but their customs as well. This helped Archer settle a misunderstanding between him and the aliens. Affected by a spatial anomaly that caused obsessive behavior in the crew, Sato was determined to duplicate one of her grandmother's dishes. (ENT: "Minefield", "A Night in Sickbay", "Singularity")

During her first experience with the transporter in 2152, Sato imagined she was starting to disappear after returning to Enterprise, and that aliens were attempting to destroy the ship. While attempting to stop them, she materialized on Enterprise and discovered she had imagined it all while being caught in the pattern buffer for several seconds. (ENT: "Vanishing Point")

Brannon Braga regarded Sato's fear of becoming insignificant as "something a lot of people can relate to." (Star Trek: Communicator issue 145, p. 26)

In an ultimately omitted scene from the final draft script of "Stigma", Sato admitted to having missed being in a large city before she had visited one on Dekendi III. [1] Not even any evidence of her visiting that planet is evident in the final version of "Stigma", though.

Sato's body was taken over by alien entities that wished to steal Enterprise. The alien who took over her body attacked Phlox, who was trying to find a way to drive the aliens from the crew's bodies. (ENT: "The Crossing")

The Xindi mission[]

Hoshi Sato, 2153

Ensign Sato on the bridge in 2153

Sato participated in Enterprise's mission to find and destroy the Xindi weapon in the Delphic Expanse. (ENT: "The Expanse", et al.)

In a deleted scene from "The Expanse", Sato packed some belongings in her quarters and had a conversation with Archer. She mentioned she thought she had to "brush up" on her Japanese, so she could be more conversant with her parents, though Archer was doubtful of that. Alhough he assumed she was intending to leave Enterprise rather than go on the Xindi mission, she eventually explained that she was actually sending the items to her mother, in order to clear shelf space for some xenolinguistic books she hadn't read yet. Suspecting Archer might think she couldn't handle herself on the new mission, Sato told him, "I don't know what's inside this Expanse, sir, but I think I've proven that I can handle myself in difficult situations... and even provide a little help along the way." She confirmed Archer had no problem with her remaining aboard. As he then exited awkwardly, Sato continued packing.

In early 2153, Sato, along with Jonathan Archer and Malcolm Reed, were infected by a virus, left behind by the extinct Loque'eque race, that transformed her into a Loque'eque. She, along with Reed and Archer, were cured by Phlox. (ENT: "Extinction")

During contact with the Osaarians, Sato discovered a manifest. After translating it, she discovered that the race had been in a battle with the Xindi, leading Archer to interrogate the Osaarians and obtain valuable information about the Xindi. (ENT: "Anomaly (ENT)")

Reed, Archer, and Sato meet Tarquin

Sato meeting Tarquin with Archer and Reed

In October 2153, Sato was telepathically contacted by Tarquin, an exile residing on a nearby planet. Tarquin told Sato that she had a unique mind, one of a few that he could connect to on a deep level. He tried to force her to stay with him in exchange for providing Enterprise with information on the Xindi, but Sato refused, despite his claims that he understood her loneliness better than anyone ever could. Tarquin later provided information on the Xindi. (ENT: "Exile")

Sato helped take the ship back after Archer, infected by Xindi toxin, endangered the mission. She discovered that the pod Archer was returned in after the battle of Azati Prime contained a message that Degra, leader of the Xindi-Primates, wished to meet with Archer. (ENT: "Hatchery", "Damage")

In February 2154, Sato was kidnapped by Commander Dolim. Using Xindi neural parasites, she was compelled to assist the Xindi-Reptilians in decrypting the Xindi-Aquatic activation codes for the Xindi weapon. Sato fought bravely against them, scrambling the codes further and even attempting to kill herself to prevent them from gaining access to the codes. The Xindi-Reptilians eventually forced her to comply and she decrypted the codes, but was subsequently rescued by a team of MACOs led by Major Hayes. Although Sato was still suffering from the effects of the parasites, Archer insisted that she accompany his team in their attempt to destroy the weapon. Sato was successful in decrypting the schematics for the weapon, allowing Archer to successfully destroy it from within. (ENT: "The Council", "Countdown", "Zero Hour")

The return home[]

Hoshi tries to escape

Sato escapes the decontamination chamber, suffering from the silicon-based virus

Some months after Enterprise's return to Earth, Sato was infected with a silicon-based virus while part of a landing party on a planet's surface, looking for salvage among Klingon waste. While quarantined in the decontamination chamber and in a delirious state, she displayed skill in decrypting the locking sequence for doors on the entire deck, causing a ship-wide quarantine breach alert. Although Sato initially died due to the virus, she was cured by two Organian observers, who were watching the crew's reaction to the virus. (ENT: "Observer Effect")

Sato participated in Enterprise's effort to capture Augments whose action threatened the peace between Earth and the Klingons. Also, she served during the Vulcan Reformation and the Klingon Augment Crisis.

In January 2155, Sato was responsible for improvements made to the universal translator. During the Terra Prime crisis, Captain Archer left her in command of Enterprise, fondly recalling when she used to jump every time the engines hiccuped. Hoshi replied that she still did, she had just gotten better at hiding it. While the rest of the senior staff were rescuing Trip Tucker and T'Pol from the surface of Mars, Sato disobeyed orders from Nathan Samuels to destroy the array after the deadline for all non-Humans to leave the Sol system had passed, despite her orders left by Archer to destroy the verteron array if his team could not stop it from firing on San Francisco, hoping Archer would stop Terra Prime in time; going as far as to prevent Samuels from contacting Admiral Gardner. Luckily, Tucker managed to alter the target so the array fired into the ocean, just as Sato was about to open fire. (ENT: "Demons", "Terra Prime")

Final Mission aboard the Enterprise[]

Sato was still serving aboard Enterprise with the rank of ensign when the ship was decommissioned in 2161. After the ship's final mission to rescue Talla, the daughter of the Andorian Shran, and following the death of her crewmate, Commander Charles Tucker III, she attended the historic founding ceremony of the United Federation of Planets in San Francisco. Sato presumably returned to Brazil a few weeks after the ceremony, as she told Travis Mayweather. (ENT: "These Are the Voyages...")

Later career[]

Starfleet biography of Sato, circa 2268

Following the signing of the Federation Charter, Sato went on to serve in the Federation Starfleet for a time. She retired from Starfleet with the rank of Lieutenant Commander, sometime in the mid-2160s, and went on to develop the linguacode translation matrix. (ENT: "In a Mirror, Darkly, Part II") By the end of her career, she was known to speak 86 languages. (SNW: "Those Old Scientists")

Sato was married at some point and died prior to 2268. (ENT: "In a Mirror, Darkly, Part II")

Sato's biographical data seen in "In a Mirror, Darkly, Part II", was written entirely by episode writer Michael Sussman. 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. This would have made her 117 at the time of her death. Governor Kodos ordered the deaths of Sato and the others in order to save the rest of the colony. She was buried in Kyoto with her husband, Takashi Kimura. [2](X) [3] [4](X)


As a crewmember aboard the NX-01 and pivotal contributor to the development of the widely-deployed universal translator, Sato became a revered figure in the annals of Federation and Starfleet history. As a cadet at Starfleet Academy, Nyota Uhura wrote three papers on Sato, something which she mentioned in 2259 while describing her admiration for Sato's life and career. Uhura went on to follow in Sato's footsteps by becoming the communications officer of the first Federation starship USS Enterprise. (SNW: "Those Old Scientists")

A holographic representation of Sato was part of an historic 24th century holodeck program depicting the final voyage of Enterprise NX-01. This program was accessed aboard the USS Enterprise-D by Commander William T. Riker in 2370. (ENT: "These Are the Voyages...")

Alternate timelines[]

Hoshi Sato, 2165

Hoshi as XO of Enterprise in 2165

In an alternate timeline where Earth was destroyed by the Xindi, Sato had been promoted to lieutenant by 2165 and was the executive officer of Enterprise. She was killed that year when the bridge of Enterprise was destroyed in a Xindi attack in the Ceti Alpha system. (ENT: "Twilight")

In another timeline where Enterprise inadvertently traveled back in time to 2037, Sato had two children: a boy named Toru and a girl named Yoshiko. She had died by the year 2154. (ENT: "")



Background information[]

Hoshi Sato was played by Linda Park.

Sato's given name of Hoshi means "star" in Japanese, a fact which is likely not coincidental. Her translated name appears in katakana in the Japanese dubs of the series. "Sato" (also written Satou) is the most common of Japanese surnames and usually written with characters meaning help/assistant and wisteria. However, the dropping of the "u" may be intentional – "sato" means home/village, so she's "at home in the stars."

Hoshi Sato was conceived as a feisty but somewhat astrophobic character. Series co-creator and Executive Producer Brannon Braga explained, "In our minds, especially initially, we saw Hoshi Sato as a real point-of-view character [...] We wanted to show, what would it be like when you go to warp and the ship rumbles, and if you're a white-knuckle flyer like Hoshi, what would that be like?" ("Broken Bow" audio commentary, ENT Season 1 DVD/Blu-ray)

In the series bible for Star Trek: Enterprise, Ensign Hoshi Sato was described thus; "Com Officer. Human, late twenties, Japanese. Striking and intelligent, Hoshi has a feisty spirit that often tests the patience of the crew. She's in charge of communications systems on the Enterprise, but she also serves as ship's Translator. An expert in exo-linguistics, she learned to manipulate her vocal chords to emit a range of alien sounds no Human has ever produced. Hoshi has a natural affinity for picking up languages. Give her ten minutes with a Klingon, and she'll be chatting about the weather on Kronos." The document went on to say that, owing to difficulties with the universal translator, "Hoshi must always be prepared to step in and act as intermediary." The series bible further commented, "Hoshi doesn't like the idea of being trapped in a 'tin can' hurtling at impossible speeds. Every time the Enterprise jumps to warp, she grips her console and closes her eyes. She's a 'white knuckle' space-farer." Thereafter, a description of the relationship between Hoshi and T'Pol followed, the series bible remarking, "[They] are like oil and water. Hoshi loves to tweak the Vulcan; get her to show emotion. This unlikely duo will share a conflictual relationship... but in the field, they'll be like sisters. They'd die for each other."

Brannon Braga and fellow series co-creator and Executive Producer Rick Berman were obviously looking for an Asian actress to play Hoshi Sato. ("Broken Bow" audio commentary, ENT Season 1 DVD/Blu-ray) Other aspects of the role were outlined in a character breakdown sheet that Paramount sent to talent agents upon seeking an actress for the part. There, Hoshi Sato was described thus; "Comm Officer. Japanese. Mid to late 20s. Striking and intelligent, Hoshi has a feisty spirit that often tests the patience of the crew. She's in charge of communications on Enterprise, but she also serves as ship's Translator. An expert in exo-linguistics, she learned to manipulate her vocal chords to emit a range of alien sounds no Human has ever produced. She has a natural affinity for picking up languages. Hoshi doesn't like the idea of being trapped in a 'tin can' hurtling at impossible speeds. Every time the ship jumps to warp she grips her console and closes her eyes. She's a 'white knuckle' space farer." [5]

In the revised final draft script of ENT: "Broken Bow", Hoshi Sato is initially described as "a spirited young woman." [6]

Linda Park's portrayal of Hoshi Sato immediately impressed the producers. "When Linda came along," Rick Berman recalled, "she just knocked us out; she was perfect for our communications person, our linguist." ("Broken Bow" audio commentary, ENT Season 1 DVD/Blu-ray) Despite having been a big fan of Star Trek: The Next Generation in her childhood, Park didn't want her interpretation of Sato to be influenced by that. "I really wanted to approach it from a fresh standpoint: not as an actor saying 'OK, I'm in a Star Trek world,' but as myself and how I would feel going out in space for the first time," Park related. "I didn't want there to be a status quo about how I should feel about that." (Star Trek: The Magazine Volume 2, Issue 7, p. 22)

As the series continued, Rick Berman felt Hoshi Sato remained an asset to the series and that they "managed to continue to need Hoshi, and to get a lot of story material and also a lot of humor out of the fact that we need her to help us translate." Brannon Braga believed that, when first introduced, Hoshi is depicted as "a very feisty character" but that this quality was lessened while the series progressed. "Once she got on board and essentially became terrified," Braga laughed, "[when] everything was happening, she lost a bit of her edge, as the episodes went by. I think we envisioned her as a bit more feisty than she ended up becoming." ("Broken Bow" audio commentary, ENT Season 1 DVD/Blu-ray)

Early promotional material around the character of Hoshi Sato stated that she had at some point undergone surgery to her voicebox in order to be able to speak extraterrestrial languages that would normally be beyond Human capacity. This fact was never stated in any episode, however. (Star Trek: The Magazine(citation needededit))

Chronologically, Hoshi is the earliest known member of Starfleet to hold the rank of lieutenant commander. Since the rank never appeared in the run of Star Trek: Enterprise up until after the formation of the United Federation of Planets, it appears the rank didn't exist before that point, an hypothesis which is supported by comments from costumers who agree that rank couldn't have existed any earlier in Star Trek history. (Star Trek: The Magazine(citation needededit))

The communications officer of the Battlestar Pegasus and later Galactica on the Ronald D. Moore-produced Battlestar Galactica is, coincidentally or not, also named Hoshi, although this is his last name.


According to author David Greven, "Ensign Hoshi Sato is an Asian American linguist and the communications officer. Prone to fearful fits and generally seen as ineffectual in any terms other than the linguistic aspects of her job, Hoshi is the resident screamer." (Gender and Sexuality in Star Trek (David Greven 2009), p. 123)]

In their reference book Beyond the Final Frontier (p. 375), critics Mark Jones and Lance Parkin commented, "After two seasons, Hoshi hasn't made an impact." (Google Books snippet view)

In 2020, Sato was named by Kath Leroy of Screen Rant as one of Star Trek's "five best crew members of all time": Hoshi could have been insecure at times and she was a bit of a loner and a perfectionist, so she wasn't perfect. But guess what? Neither were any of her fellow crew members. [7]
