手術する

The Japanese verb 手術する (shujutsu suru) is a fundamental medical term that translates directly to 'to perform surgery' or 'to have an operation.' It is a compound verb consisting of the noun 手術 (shujutsu), meaning 'surgery' or 'surgical operation,' and the light verb する (suru), which means 'to do.' In the hierarchy of Japanese medical vocabulary, this term is considered standard and formal, used by doctors, nurses, and patients alike to describe the act of medical intervention involving manual or instrumental treatment of a physical condition. To understand the depth of this word, one must look at the kanji characters. The first character 手 (te) means 'hand,' signifying the manual nature of the work. The second character 術 (jutsu) means 'art,' 'technique,' or 'skill.' Together, they literally describe the 'technique of the hand,' which perfectly encapsulates the essence of surgery as both a medical science and a technical craft.

Medical Context

Used primarily in clinical settings to describe invasive procedures ranging from minor stitches to major organ transplants.

General Usage

Commonly heard in daily conversations when discussing health issues of family members, friends, or even pets.

The term is highly versatile because of the 'suru' ending. Depending on the context and the particle used, it can indicate that a surgeon is performing the act or that a patient is undergoing the procedure. For example, 医者が手術する (Isha ga shujutsu suru) means 'The doctor performs surgery,' whereas 患者が手術する (Kanja ga shujutsu suru) often implies the patient is receiving the surgery, though in formal writing, 手術を受ける (shujutsu o ukeru) is more precise for 'receiving' surgery. This nuance is crucial for B1 level learners who are beginning to navigate more complex social and professional situations in Japanese. The word is frequently encountered in news reports concerning public figures or in the plotlines of popular Japanese medical dramas like 'Doctor-X' or 'Code Blue,' where the technical skill of the surgeon is often the central theme.

Furthermore, the word extends beyond human medicine. It is equally applicable in veterinary contexts when a pet needs an operation. In a metaphorical sense, though rare, it can sometimes be used in business or engineering to describe a 'surgical' or highly precise intervention in a complex system, although 抜本的な改革 (bapponteki na kaikaku) is more common for 'radical reform.' When using this word, it is important to remember that it is a Kango (Sino-Japanese word), which gives it a more clinical and serious tone compared to native Japanese words. In casual settings, people might shorten it or use the loanword オペ (ope), derived from the English 'operation,' but 手術する remains the gold standard for clear communication in all levels of Japanese society.

Using 手術する (shujutsu suru) correctly requires an understanding of Japanese verb conjugation and particle usage. As a suru-verb (Group 3), it follows the standard pattern: shujutsu shimasu (polite), shujutsu shinai (negative), shujutsu shita (past), and shujutsu shite (te-form). The most common particle used with this verb is を (o) to indicate the body part being operated on, or simply to turn the noun into a direct object of the action.

Direct Object (Patient View)

[Body Part] + を + 手術する. Example: 目を手術する (To have surgery on one's eyes).

Subject (Doctor View)

[Doctor] + が + [Patient] + を + 手術する. Example: 先生が患者を手術する (The doctor operates on the patient).

In many cases, when the patient is the subject, Japanese speakers prefer the passive form 手術される (shujutsu sareru) or the compound 手術を受ける (shujutsu o ukeru). However, 手術する is frequently used in the active voice even by patients when they are discussing their plans or decisions: 「手術することに決めた」 (I decided to have the surgery). This usage emphasizes the decision-making process rather than the physical act of being operated upon. For medical professionals, the verb is almost always active, often paired with adverbs that describe the duration or complexity of the procedure, such as 緊急で (kinkyuu de - urgently) or 無事に (buji ni - successfully).

Another important grammatical aspect is the use of the potential form 手術できる (shujutsu dekiru), which means 'can perform surgery' or 'surgery is possible.' This is often used in medical consultations to discuss whether a condition is operable. Conversely, 手術できない (shujutsu dekinai) indicates that a condition is inoperable. When describing the location of the surgery (the hospital or the operating room), the particle で (de) is used: 大きな病院で手術する (To have surgery at a large hospital). Understanding these particle nuances ensures that you don't just know the word, but can actually build coherent sentences that convey the correct relationship between the doctor, the patient, and the procedure.

In Japan, you will encounter the word 手術する (shujutsu suru) in a variety of environments, ranging from the highly professional to the deeply personal. The most common place is, naturally, the hospital (病院 - byōin). If you are visiting a clinic for a persistent issue, a doctor might use this term to explain the next steps of your treatment. It is also a staple of Japanese television. Medical dramas are a massive genre in Japan, and characters will frequently shout about the need to 手術する in high-stakes, dramatic operating room scenes. In these shows, you might also hear the shortened version オペ (ope), which is commonly used among medical staff in real life for efficiency.

News & Media

Announcements about celebrities or politicians undergoing surgery always use '手術する' to maintain a respectful and objective tone.

Workplace Conversations

If a colleague is taking a long leave of absence for health reasons, they might inform their manager by saying they need to '手術する'.

You will also hear this word in the context of family discussions. Japan has an aging population, so conversations about elderly relatives needing surgery for cataracts, hip replacements, or more serious conditions are quite common. In these settings, the word is used with a sense of gravity and concern. It is also found in literature and manga, particularly in stories that deal with human drama, life, and death. Because the word is so specific, it doesn't have many 'casual' variations other than 'ope,' so when you hear it, you know exactly what is being discussed.

Lastly, you might see this word on official documents, insurance forms, and medical consent slips. In these written contexts, the noun form 手術 is more frequent, but the verb form is used in the instructions, such as 「手術する前に絶食してください」 (Please fast before having surgery). For a B1 learner, being able to recognize and respond to this word is essential for navigating the Japanese healthcare system or simply being a supportive friend to someone going through a medical challenge. It is a 'high-frequency' word in the sense that while surgery isn't a daily event, the word itself is the only way to describe the event when it does happen.

One of the most frequent mistakes English speakers make when using 手術する (shujutsu suru) is related to the confusion between 'performing' and 'receiving' surgery. In English, we often say 'I am having surgery,' which can be translated as 手術する, but beginners sometimes get confused about who is doing what. If you say 私が手術する (Watashi ga shujutsu suru), it could technically mean 'I am the surgeon.' While context usually clears this up, it is safer for a patient to say 手術を受ける (shujutsu o ukeru - to receive surgery) to avoid any ambiguity, especially in formal medical settings.

Pronunciation Error

Saying 'shujitsu' (which means 'holiday' or 'day of the week') instead of 'shujutsu'. This can lead to very confusing sentences!

Particle Confusion

Using 'に' (ni) instead of 'を' (o) for the body part. Correct: 足を手術する. Incorrect: 足に手術する.

Another mistake involves the misuse of the word in non-medical contexts. In English, we might 'surgically' remove a problem in a business plan, but in Japanese, 手術する is almost exclusively reserved for biological organisms (humans and animals). Using it for a broken machine or a computer program would sound very strange and metaphorical in a way that Japanese doesn't typically favor. For machines, use 修理する (shuuri suru - to repair) or 分解する (bunkai suru - to disassemble).

Finally, watch out for the conjugation of suru. Because it's an irregular verb, some learners forget the 'shita' past tense and try to say 'shujutsu-ed' or use the wrong form. Also, ensure you are not confusing it with 技術 (gijutsu - technology/skill). Both share the 'jutsu' kanji, but their meanings are entirely different. Always remember that shujutsu requires the 'shu' (hand) kanji. By paying attention to these common pitfalls—pronunciation, patient vs. doctor perspective, and appropriate context—you will be able to use 手術する with the precision of a surgeon.

While 手術する (shujutsu suru) is the most common way to say 'to perform surgery,' Japanese offers several alternatives depending on the level of formality and the specific nature of the procedure. Understanding these synonyms helps you sound more natural and allows you to understand a wider range of medical dialogue. The most common informal alternative is オペする (ope suru). This is a loanword from the English 'operation.' It is used frequently by medical professionals in casual conversation or when they want to be brief. It is also common in medical TV shows to add a sense of 'insider' realism.

手術する vs. オペする

手術する is the standard, formal term. オペする is medical jargon/slang used for brevity among staff or in casual settings.

手術する vs. 執刀する (shittō suru)

執刀する literally means 'to hold the knife.' It is a very formal and professional way to say 'to lead the surgery' or 'to be the primary surgeon.'

Another related term is 処置する (shochi suru), which means 'to treat' or 'to deal with.' This is a broader term that includes non-surgical treatments like cleaning a wound or applying a bandage. If a doctor says they will 'shochi suru,' it might not involve a full surgery. For very specific types of surgery, Japanese uses compounds. For example, 移植する (ishoku suru) means 'to transplant,' and 切開する (sekkai suru) means 'to make an incision.' These are more technical and are used to describe the specific actions taken during the shujutsu.

Lastly, there is the term 外科的処置 (geka-teki shochi), which means 'surgical treatment.' This is a very formal, academic way to refer to the concept of surgery in a medical paper or a formal diagnosis. For a B1 learner, stick to 手術する for 90% of situations, but keep 'ope' in your back pocket for when you're watching your favorite medical J-drama. Knowing the difference between these terms allows you to tailor your speech to your audience—whether you're talking to a doctor, a friend, or reading a technical report.
