الشرح 注射する in your Level:

At the A1 level, you only need to know that '注射' (chūsha) means 'a shot' or 'an injection' and that '注射する' is the action. You might hear this at a doctor's office in Japan. It is often used with '痛い' (itai - painful). A beginner should focus on recognizing the word in a medical context. You don't need to worry about complex grammar yet; just knowing 'Chūsha shimasu' (I'm going to give you a shot) or 'Chūsha wa kirai desu' (I hate shots) is enough. The word is very common in basic health conversations. Remember that 'suru' makes it a verb. Even if you can't conjugate it perfectly, using 'Chūsha' plus a pointing gesture will get your point across to a Japanese doctor. It's an important word for safety and health.

At the A2 level, you should be able to use '注射する' in basic sentences with particles. You should know that '腕に注射する' means 'to inject in the arm.' You should also start to recognize the difference between '注射する' (to inject) and '注射を打つ' (to get/give a shot), which is a common idiomatic way to say it. At this level, you might describe a past experience: '昨日、病院で注射しました' (I had a shot at the hospital yesterday). Note that while 'shita' is active, in casual speech, people often use it to mean they received the shot. However, learning the passive '注射された' (was injected) is a good goal for the end of the A2 level. You should also be familiar with 'yobō sesshu' (vaccination) as a related noun.

At the B1 level, you are expected to use '注射する' accurately in various social and medical situations. You should understand the nuance of the benefactive form '注射してもらう' (to have someone give you a shot), which is the most polite and natural way for a patient to describe the event. You should also be able to discuss the necessity of injections, such as for allergies or chronic conditions like diabetes: 'アレルギーのために注射しなければなりません' (I must have an injection for my allergies). At this level, you should be comfortable with the potential form '注射できる' (can inject) and the causative form '注射させる' (to make someone inject). You should also begin to distinguish '注射する' from more formal terms like '接種する' (to vaccinate).

At the B2 level, you should understand '注射する' in more technical or abstract contexts. You might encounter it in news reports about public health or medical breakthroughs. You should be able to use it in complex sentences involving conditions or hypotheses: 'もしその薬を注射していれば、助かったかもしれない' (If they had injected that medicine, they might have been saved). You should also know the specific types of injections like '静脈注射' (intravenous) and '筋肉注射' (intramuscular). At this level, you can also understand the metaphorical use of the kanji in words like '注入' (chūnyū - injection of capital/energy), though you'll know that '注射する' itself remains literal. Your ability to use Keigo (honorifics) when a doctor speaks to a patient using this verb should be solid.

At the C1 level, you should have a nuanced understanding of '注射する' within the broader medical and legal landscape of Japan. This includes understanding the legalities of who is allowed to '注射する' (doctors and nurses) and the nuances of '自己注射' (self-injection) protocols. You should be able to discuss medical ethics or the history of medicine using this term. You will recognize the verb in academic papers or high-level journalism. You should also be able to navigate the subtle differences between '注射', '穿刺', and '投与' in a professional medical environment. Your command of the passive and causative-passive forms ('注射させられる' - to be made to have an injection) should be perfect, reflecting complex social dynamics or medical requirements.

At the C2 level, you possess a native-like command of '注射する'. You can understand and use the word in any context, from highly specialized medical discourse to poetic or literary descriptions. You might encounter it in literature where a needle prick is described with sensory detail, or in philosophical debates about medical intervention. You understand the historical evolution of the kanji and how the term has been used in Japanese society over the last century. You can effortlessly switch between colloquialisms like '打つ' and technical terms like '皮下注射', depending on the audience. You are also aware of the social stigmas or cultural attitudes toward injections in Japan compared to other countries, and can articulate these differences using sophisticated vocabulary.

注射する في 30 ثانية

A B1-level medical verb meaning 'to inject' or 'to give/get a shot' using a needle and syringe.
Commonly used in clinics, hospitals, and when discussing vaccinations or chronic illness management.
Requires careful use of active and passive forms: patients usually 'receive' the shot (chūsha shite morau).
Essential for health-related conversations, flu season, and understanding instructions at a Japanese pharmacy.

The Japanese verb 注射する (chūsha suru) is a compound verb consisting of the noun 注射 (injection) and the helper verb する (to do). In its most literal sense, it refers to the medical act of introducing a liquid—usually medicine, a vaccine, or a nutrient solution—into the body using a needle and syringe. While it is a technical medical term, it is the standard, everyday way to say 'to give a shot' or 'to get an injection' in Japanese. Unlike English, where we often distinguish between 'getting a shot' (passive/patient perspective) and 'giving a shot' (active/practitioner perspective), Japanese uses 注射する for the act itself, often relying on the passive form 注射される or the receiving verb 注射をしてもらう to clarify the patient's experience.

Medical Context: Used by doctors and nurses when performing the procedure. For example, '腕に注射しますね' (I'm going to give you a shot in the arm).
Patient Experience: Used by patients describing their visit. 'インフルエンザの予防接種で注射した' (I got a shot for the flu vaccination).
Scientific/Formal: Found in medical reports or pharmaceutical instructions to describe drug delivery methods.

看護師さんは私の腕に素早く注射した。(The nurse quickly injected my arm.)

The word carries a slightly clinical nuance compared to more colloquial expressions, but it is by no means 'too formal' for daily life. In Japan, regular health checkups and seasonal vaccinations are very common, so you will encounter this word frequently in winter during flu season or when visiting a clinic for a common cold. Interestingly, children often use the word with a sense of fear, leading to the common phrase 注射が怖い (I'm scared of shots). In a broader sense, while chūsha is almost exclusively medical, you might occasionally see the kanji for 'inject' (注) used in metaphorical contexts like 注入する (to pour into/inject capital), but 注射する itself remains firmly rooted in the world of needles and medicine.

痛くないように注射してください。(Please inject me so it doesn't hurt.)

Etymology Breakdown: 注 (Pour/Focus) + 射 (Shoot/Radiate). Literally 'to pour by shooting'.

In summary, 注射する is an essential B1-level verb for anyone navigating the Japanese healthcare system or discussing health. It covers the spectrum from a simple flu shot to complex intravenous therapy. Understanding its usage involves recognizing that it is a suru-verb, meaning its conjugation follows standard patterns, making it versatile across different levels of politeness.

毎日、インスリンを注射する必要があります。(It is necessary to inject insulin every day.)

Using 注射する (chūsha suru) correctly requires an understanding of Japanese particles and the direction of the action. The most common particle associated with the location of the injection is に (ni), which marks the part of the body being injected. The substance being injected is marked with the object particle を (o). For example, '腕にワクチンを注射する' (to inject a vaccine into the arm). Because this is a medical procedure, the level of politeness (Keigo) often changes depending on who is speaking to whom.

Active Voice (The Doctor/Nurse): '今から注射します' (I will now perform the injection). This is direct and professional.
Passive Voice (The Patient): '病院で注射された' (I was injected at the hospital). Often implies a slightly negative or forced experience, which is common with medical procedures.
Benefactive (Polite Patient): '先生に注射してもらった' (I had the doctor give me a shot). This is the most natural way for a patient to describe the event, acknowledging the service provided.

彼は自分自身に薬を注射することができない。(He cannot inject the medicine into himself.)

When talking about vaccinations, 注射する is often replaced or supplemented by 予防接種を受ける (yobō sesshu o ukeru - to receive a vaccination), but in the moment of the needle entering the skin, 注射する is the specific verb used. In veterinary contexts, the usage remains the same: '犬に狂犬病のワクチンを注射する' (to inject a rabies vaccine into a dog). The grammar remains consistent regardless of the patient (human or animal). It is also important to note that 注射 is a noun, so you can say '注射は痛い' (Shots are painful) without the verb する.

その薬剤は静脈に注射しなければならない。(That drug must be injected into a vein.)

For advanced learners, it's worth noting the distinction between different types of injections: 静脈注射 (jōmyaku chūsha - intravenous), 筋肉注射 (kinniku chūsha - intramuscular), and 皮下注射 (hika chūsha - subcutaneous). When these nouns are used with する, they describe the specific medical technique. In everyday conversation, however, just 注射する is sufficient. If you want to describe the act of 'getting a shot' in a very casual way, you might hear 注射を打つ (chūsha o utsu), where 'utsu' (to hit/strike) is used colloquially for injections, much like 'hitting' a vein in English slang, though in Japanese it is standard colloquialism, not necessarily drug-related.

麻酔を注射した後、手術が始まった。(After injecting the anesthesia, the surgery began.)

The most common place to hear 注射する (chūsha suru) is, unsurprisingly, in medical facilities. In Japan, clinics (kurinikku) and hospitals (byōin) are the primary settings. You will hear nurses say it as they prepare the equipment. For example, '少しチクッとしますよ、注射しますね' (It'll be a little prick, I'm going to inject now). This 'chiku-tto' (onomatopoeia for a small prick) often precedes the verb in a clinical setting to warn the patient.

Pediatric Clinics: You'll hear parents comforting children: '注射、頑張ろうね' (Let's be brave for the shot). Here, the noun is used, but the action is implied.
News Reports: During vaccination campaigns (like COVID-19 or the flu), news anchors will use '注射する' or '接種する' (sesshu suru - to inoculate) to describe the progress of the rollout.
Medical Dramas: In shows like 'Doctor-X' or 'Code Blue', surgeons and nurses use the term frequently when administering emergency medication.

「はい、力を抜いてください。注射しますよ。」("Okay, please relax. I'm going to give you the injection.")

Beyond the clinic, you might hear it in pharmacy settings when discussing self-injection medications like insulin for diabetes. Pharmacists will instruct patients on '自己注射する' (jiko chūsha suru - to self-inject). This is a vital phrase for patients who need to manage chronic conditions at home. In a completely different vein, you might hear it in sports news regarding 'doping' scandals, where the term '禁止薬物を注射する' (to inject prohibited substances) is used to describe illegal performance enhancement.

彼は毎日、自分でインスリンを注射している。(He injects insulin himself every day.)

Finally, in anime and manga, '注射する' is often used in sci-fi or horror settings. Think of a mad scientist injecting a mysterious serum into a test subject. The phrase '謎の薬を注射された' (I was injected with a mysterious medicine) is a common trope. Whether in a mundane clinic or a high-stakes drama, the word remains the primary way to describe the act of using a needle to deliver a substance.

犯人は被害者に強力な睡眠薬を注射した。(The criminal injected a powerful sedative into the victim.)

One of the most frequent mistakes English speakers make with 注射する (chūsha suru) is confusing the active and passive forms. In English, we say 'I got a shot,' which sounds active but describes a passive experience. In Japanese, if you say '注射した' (chūsha shita), it sounds like you were the one holding the needle and sticking it into someone. Unless you are a doctor or nurse, you should usually say '注射された' (passive) or '注射を打ってもらった' (benefactive).

Mistake: Active vs. Passive: Saying '昨日、注射した' (Yesterday, I injected [someone]) instead of '昨日、注射してもらった' (Yesterday, I received an injection).
Mistake: Confusing with 'Sesshu': Using '注射する' for oral vaccines or nasal sprays. '注射' specifically implies a needle. For general vaccination, '接種する' (sesshu suru) is broader.
Mistake: Particle Errors: Using 'を' for the body part. It should be '腕に' (into the arm), not '腕を' (inject the arm itself, though this is occasionally heard, 'ni' is more precise for the destination).

❌ 私は病院で注射した。(I performed an injection at the hospital - incorrect if you are the patient.)

Another common error is applying '注射する' to non-medical contexts where 'inject' might work in English. For example, in English, you can 'inject humor into a speech' or 'inject life into a party.' In Japanese, using 注射する here would be very strange and likely misunderstood as a literal medical reference. For metaphorical injections, use verbs like 取り入れる (toriireru - to incorporate) or 加える (kuwaeru - to add).

✅ 病院で注射を打ってもらった。(I had a shot given to me at the hospital.)

Finally, be careful with the kanji. 注 (to pour) is also used in 注意 (chūi - caution) and 注文 (chūmon - order), while 射 (to shoot) is used in 放射 (hōsha - radiation) and 発射 (hassha - launch). Mixing these up with similar-looking kanji like 住 (live) or 謝 (apologize) is a common beginner mistake in writing.

看護師は患者の静脈に慎重に注射した。(The nurse carefully injected into the patient's vein.)

While 注射する (chūsha suru) is the most common term, several related words describe similar actions or contexts. Understanding the nuances between them will help you sound more natural and precise in Japanese.

接種する (Sesshu suru): Meaning: To inoculate or vaccinate. This is a broader term that refers to the medical goal (preventing disease) rather than the physical act of using a needle. It can include oral vaccines.
点滴する (Tenteki suru): Meaning: To give/receive an IV drip. While it involves a needle, it refers to the slow, continuous administration of fluids, usually in a hospital bed.
注入する (Chūnyū suru): Meaning: To inject or pour into. This is used for non-medical contexts, such as 'injecting capital into a company' or 'pouring air into a tire'.
投与する (Tōyo suru): Meaning: To administer (medicine). This is a formal medical term that covers all methods of giving medicine, including pills, injections, and ointments.

インフルエンザのワクチンを接種する。(To receive a flu vaccine - focus on the goal.)

The choice between 注射する and 打つ (utsu) is largely one of formality. 注射する is the standard verb, whereas 注射を打つ is more idiomatic and common in spoken Japanese. If you are talking to a child, you might even use the very cute and informal チックンする (chikkun suru), which comes from the 'chiku-tto' sound of a needle prick. On the other hand, in a medical textbook, you are more likely to see 穿刺する (senshi suru - to puncture/pierce), which is a highly technical term for inserting a needle for various purposes, not just injection.

脱水症状のため、点滴した。(I had an IV drip due to dehydration.)

In summary, while 注射する is your 'go-to' word for shots, being aware of 接種 for vaccines and 点滴 for drips will make your Japanese much more precise. If you're talking about money or abstract ideas, steer clear of 注射 and use 注入 or 導入 instead.

新しいプロジェクトに資金を注入する。(To inject funds into a new project.)

نصائح

Use Benefactive Forms

As a patient, always prefer '注射してもらう' or '注射を打ってもらう' over the simple active '注射した' to sound more natural and polite.

Warn Others

If you are playing a role or helping someone, use '注射しますよ' (I'm going to inject) as a polite warning.

Learn the Syringe

The tool is '注射器' (chūshaki). Knowing the tool name helps in medical conversations.

Expect the 'Chiku-tto'

Japanese medical staff almost always use the onomatopoeia 'chiku-tto' to describe the sensation. Learning this will help you understand their warnings.

Focus on 'Sha'

The kanji 射 (shoot) is the most unique part of the word. Associate it with archery to remember its meaning of 'discharging' medicine.

Don't rush the 'Chū'

The long 'u' is important. If you say it too short, it might sound like a different word or just be hard to understand.

Metaphors

Avoid using '注射する' for non-medical things. Use '注入' (chūnyū) for 'injecting energy' or 'injecting money'.

Aftercare

Listen for 'monai de kudasai' (please don't rub). Nurses often tell you not to rub the injection site.

Use 'Chikkun'

If talking to a Japanese child about a shot, 'chikkun' is much more effective and less scary than 'chūsha'.

احفظها

وسيلة تذكّر

Think of a 'CHOO-CHOO' train (Chū) 'SHArp' needle (Sha) 'SURU' (doing). A sharp needle train doing an injection.

ربط بصري

Visualize a syringe with liquid 'pouring' (注) out as it 'shoots' (射) into an arm.

تحدٍّ

Try to use '注射する' in three different forms (active, passive, and benefactive) when describing your last visit to the dentist or doctor.

أصل الكلمة

Borrowed from Chinese kanji. '注' (chū) means to pour, flow, or focus. '射' (sha) means to shoot, radiate, or discharge.

المعنى الأصلي: To pour in by shooting (using a projectile-like force).

Sino-Japanese (Kango).

السياق الثقافي

Be mindful that some people have a phobia of needles (sentan kyōfushō). Use the word gently in such cases.

In English, we say 'get a shot' or 'give a shot.' In Japanese, 'chūsha suru' is more clinical but widely used in all registers.

The movie 'Akira' features many scenes of mysterious injections. The anime 'Cells at Work!' (Hataraku Saibō) explains how the body reacts to vaccines. Many medical dramas like 'Doctor-X' show the procedure frequently.

الأسئلة الشائعة

10 أسئلة

Technically, yes, in a professional setting. However, patients use it to describe receiving a shot, or for 'self-injection' (jiko chūsha) if they have a condition like diabetes. For example, '自分でインスリンを注射する' is perfectly correct.

'注射する' is the standard verb. '注射を打つ' is an idiomatic expression that is very common in spoken Japanese. Both are understood, but '打つ' feels slightly more casual and natural in conversation. For example, '注射を打ってもらった' is more common than '注射してもらった'.

You can say '注射が怖いです' (Chūsha ga kowai desu) or '先端恐怖症です' (Sentan kyōfushō desu), which specifically means a phobia of sharp points/needles.

No. For a mosquito bite, use '刺される' (sasareru - to be stung/bitten). '注射' is only for medical needles controlled by humans.

'腕に' (into the arm) is the most common and grammatically precise way to indicate the target. '腕を注射する' is occasionally heard but sounds a bit like you are injecting the arm itself as an object, rather than the medicine into it.

It is 'インフルエンザの予防接種' (yobō sesshu) or colloquially 'インフルエンザの注射' (chūsha).

Yes, it can. In news reports about drug abuse, you will hear '覚醒剤を注射する' (injecting stimulants).

Ask: '注射は痛いですか？' (Chūsha wa itai desu ka?). Nurses often reply: '少しチクッとしますよ' (It'll be a little prick).

Yes, '無痛注射' (mutū chūsha). Some modern clinics advertise this using very thin needles.

It means 'self-injection.' It is used for patients who must administer their own medication at home, like insulin or certain allergy treatments.
