解析 呼吸器 in your Level:
At the A1 level, you don't need to use the word '呼吸器' (Kokyūki) frequently. It is a bit difficult because it uses three kanji. Instead, you usually learn 'iki' (breath) or 'nodo' (throat). However, you might see '呼吸器' in a hospital or on a medicine bottle. Just remember that 'ko' means out, 'kyū' means in, and 'ki' means a tool or organ. So it is the 'tool for breathing.' If you see this word, it's about your lungs and how you breathe. It is a 'big word' for beginners, so don't worry about using it in daily conversation yet. Focus on recognizing it on signs or in health contexts.

At the A2 level, you are starting to learn more specific words for health. You might know 'byōki' (illness) and 'kusuri' (medicine). '呼吸器' (Kokyūki) is the formal word for your breathing system. You might see it in a news report about the weather, especially if there is a lot of dust or pollen. Doctors use this word. If you have a bad cough that won't go away, the doctor might talk about your '呼吸器.' It is good to know this word so you can understand which part of the body a doctor is talking about. It's like the difference between saying 'I can't breathe' and 'I have a respiratory issue.'

At the B1 level, you should be able to use '呼吸器' (Kokyūki) in semi-formal contexts. You are moving beyond basic survival Japanese and starting to discuss more complex topics like health and the environment. You should understand that '呼吸器' refers to the whole system, not just the lungs. You will encounter this word in compound terms like '呼吸器疾患' (respiratory diseases) or '呼吸器科' (pulmonology department). You can use it to explain your health history or discuss environmental problems like air pollution. It is a key term for expressing yourself clearly in medical situations in Japan.
At the B2 level, you are expected to use '呼吸器' (Kokyūki) naturally in professional or academic discussions. You should understand the nuances between this and related terms like '呼吸器官' or '循環器.' You might read articles about how 'PM2.5' affects the '呼吸器系' (respiratory system) or how certain exercises improve '呼吸器機能' (respiratory function). You should be comfortable using the word in passive sentences or complex grammatical structures, such as '呼吸器が侵される' (the respiratory organs are affected/attacked). This word is essential for anyone working in health, science, or safety-related fields in Japan.

At the C1 level, '呼吸器' (Kokyūki) is a basic technical term in your vocabulary. You should be able to discuss specialized medical procedures, such as '人工呼吸器' (ventilator/respirator) and its ethical implications in end-of-life care. You will encounter this word in high-level literature and medical journals. You should be able to distinguish between the anatomical '呼吸器' and the mechanical '呼吸器' (ventilator) based on context. Your mastery of this word involves not just knowing its meaning, but understanding its role in the broader Japanese medical and legal lexicon, including insurance claims and occupational health laws.

At the C2 level, you have a native-like command of '呼吸器' (Kokyūki). You can engage in deep scientific discourse about the evolution of '呼吸器' across different phyla or discuss the latest advancements in '呼吸器外科' (respiratory surgery). You understand the historical development of the term and its kanji. You can use it with absolute precision in any context, from a specialized medical conference to a high-level policy discussion about public health. You are also aware of the very subtle stylistic choices between using '呼吸器,' '呼吸器系,' and more specific anatomical terms in professional writing.

呼吸器 30秒了解

  • 呼吸器 (Kokyūki) means 'respiratory organs' or 'respiratory system' in Japanese.
  • It is a formal noun used primarily in medical, scientific, and professional settings.
  • The word is composed of kanji for 'exhale,' 'inhale,' and 'organ/tool.'
  • Commonly seen in hospitals (呼吸器科) and in discussions about air quality or smoking.

The Japanese term 呼吸器 (こきゅうき - Kokyūki) is a formal, technical noun that translates directly to 'respiratory organs' or 'respiratory apparatus.' In everyday Japanese, while people might simply say iki (breath) or hai (lungs), the word 呼吸器 is the standard terminology used in medical, biological, and formal health-related contexts. It encompasses the entire system used for breathing, including the nose, pharynx, larynx, trachea, bronchi, and lungs. Understanding this word is crucial for navigating Japanese healthcare systems, reading medical reports, or discussing health issues like asthma, pneumonia, or environmental allergies.

Anatomical Scope
This term refers to the group of organs responsible for taking in oxygen and expelling carbon dioxide. It is not limited to just the lungs but includes the entire airway path.
Clinical Setting
In hospitals, you will frequently see this word on signage. For example, '呼吸器内科' (Kokyūki Naika) refers to the Department of Respiratory Medicine (Pulmonology).

冬になると、呼吸器の病気が流行しやすくなります。 (When winter comes, respiratory diseases tend to become prevalent.)

The word is composed of three kanji: 呼 (to exhale/call), 吸 (to inhale/suck), and 器 (organ/vessel/tool). Together, they literally mean 'the tool for exhaling and inhaling.' This logical structure makes it easier for learners to remember once they break down the individual components. You will hear this word in news broadcasts discussing air pollution (PM2.5), during flu season warnings, and when athletes discuss cardiovascular and respiratory endurance training.

タバコは呼吸器系に悪影響を及ぼします。 (Smoking has a negative impact on the respiratory system.)

Usage in Biology
Used to compare different species, such as gills in fish versus lungs in mammals, both categorized as types of 呼吸器.

Using 呼吸器 correctly requires an understanding of its formal tone. It is rarely used in casual conversation to describe a simple 'stuffy nose' unless you are discussing the medical implications. Instead, it is used to group symptoms or describe the location of an ailment. It often appears as part of compound nouns like 呼吸器系 (respiratory system) or 呼吸器疾患 (respiratory disease).

彼は呼吸器の専門医に診てもらうことにした。 (He decided to be examined by a respiratory specialist.)

When discussing health maintenance, you might say your respiratory organs are weak or strong. In this context, it functions similarly to how an English speaker might say 'I have weak lungs,' but 呼吸器 covers the broader system.

Common Pattern: 呼吸器の + [Noun]
Used to describe symptoms: 呼吸器の異常 (abnormality in the respiratory organs), 呼吸器の炎症 (inflammation of the respiratory organs).

大気汚染が深刻な地域では、呼吸器を守るためにマスクが必要です。 (In areas with serious air pollution, masks are necessary to protect the respiratory organs.)

In a technical or professional report, you might see it paired with verbs like 機能する (to function). For example, '呼吸器が正常に機能している' (The respiratory organs are functioning normally). This level of precision is expected in B1 and higher Japanese proficiency, especially when transitioning from simple daily Japanese to more academic or professional registers.

You will encounter 呼吸器 in several specific environments in Japan. The most common is the healthcare system. If you have a severe cough or difficulty breathing, a receptionist at a general hospital will likely direct you to the 呼吸器内科. You will also hear it on the news during the 'Kafun' (pollen) or 'Kousa' (yellow dust) seasons. Weather forecasters and health experts use the term to warn sensitive groups about potential irritation to their respiratory systems.

本日は黄砂の影響で、呼吸器の弱い方は外出を控えてください。 (Due to the influence of yellow dust today, those with weak respiratory organs should avoid going outside.)

Another common place is in the workplace, specifically during annual health checkups (健康診断 - Kenkō Shindan). The results might categorize certain tests under the 'Respiratory' section. If you work in a factory or a construction site, safety briefings will often mention 呼吸器保護具 (respiratory protective equipment), which is the formal term for high-grade masks or respirators.

In Schools
In science class (Rika), students learn about the human body. The diagram of the lungs and windpipe will be labeled as 呼吸器系.

この薬は呼吸器の炎症を抑える効果があります。 (This medicine is effective in suppressing inflammation of the respiratory organs.)

The most frequent mistake learners make is confusing 呼吸器 (the organ/system) with 呼吸 (the act of breathing). While they share the same first two kanji, their usage is distinct. You can say '呼吸が苦しい' (Breathing is painful/difficult), but you wouldn't say '呼吸器が苦しい' because the organ itself doesn't 'feel' pain in that way—rather, the system is experiencing an abnormality.

Mistake: Over-formalization
Using 呼吸器 when you just mean 'breath.' For example, saying '呼吸器を止める' instead of '息を止める' (hold one's breath) sounds like you are surgically stopping an organ's function.

❌ 彼は呼吸器が速い。 (Incorrect: His respiratory organ is fast.)
✅ 彼は呼吸が速い。 (Correct: His breathing is fast.)

Another mistake is confusing it with 循環器 (Junkan-ki), which refers to the circulatory system (heart and blood vessels). Because the heart and lungs work so closely together, learners often mix up these two medical departments. Remember: 呼吸 (breath) = Respiratory; 循環 (circulation) = Cardiovascular.

Depending on how specific or how casual you want to be, there are several alternatives to 呼吸器. Choosing the right one depends on the 'register' (formality) and the specific part of the body you are referring to.

肺 (Hai)
The Lungs. This is the most common specific organ within the respiratory system. In casual talk, people say '肺が痛い' (My lungs hurt) rather than mentioning the whole system.
気管 (Kikan)
The Trachea/Windpipe. Used when the issue is specifically about the throat or the air tube leading to the lungs.
呼吸器官 (Kokyū Kikan)
Respiratory Organs. This is almost identical to 呼吸器 but is slightly more academic. '器' is a suffix for 'organ/apparatus,' while '器官' is the full word for 'organ.'

魚の呼吸器はエラです。 (The respiratory organ of a fish is the gills.)

When discussing the act of breathing itself, use 呼吸 (Kokyū) or the even more common 息 (Iki). For example, '息が切れる' (to be out of breath) is much more natural than anything involving the word 呼吸器.

How Formal Is It?

趣味小知识

The 'Ki' (器) in Kokyūki is the same 'Ki' used in 'Gakki' (musical instrument) and 'Shokki' (tableware). It implies a functional tool or vessel.

发音指南

UK kɒkjɯːki
US koʊkjuːki
Heiban (Flat) style in standard Tokyo Japanese, though 'kyū' is naturally emphasized due to length.
押韵词
Tsūkyūki (Ventilator) Shōkaki (Fire extinguisher - though different kanji) Chūnyūki (Injector) Kōshinki (Marching) Shōkyūki (Short break) Kōkyūki (Luxury item) Chōkyūki (Long term) Sōkyūki (Early period)
常见错误
  • Pronouncing 'kyū' as a short 'kyu'. It must be long.
  • Confusing 'ko' with 'kō'. The first syllable is short.
  • Using an English 'r' sound if there were an 'r', but here, ensure the 'k' sounds are crisp and not aspirated too much.
  • Mixing up the pitch accent with 'kokyū' (breathing), which can vary slightly by region.
  • Pronouncing 'ki' like 'key' in English (too long). Keep it short.

如何使用

frequency

Common in medical and environmental news; rare in casual chat about daily feelings.

常见错误
  • Using 呼吸器 to mean 'a single breath'. → 呼吸 (Kokyū) or 息 (Iki).

    呼吸器 is the organ, not the air or the action. You cannot 'take a kokyūki'.

  • Saying '呼吸器が痛い' for a sore throat. → 喉が痛い (Nodo ga itai).

    呼吸器 is too broad for a simple sore throat. Be specific unless the whole chest/system is involved.

  • Confusing 呼吸器 with 循環器. → 呼吸器 (Lungs/Air), 循環器 (Heart/Blood).

    These are the most commonly swapped medical terms. Remember 'Ko' = Breath.

  • Writing '吸' without the mouth radical. → 吸 (Must have 口 on the left).

    The 'mouth' radical is essential because you breathe through your mouth/nose.

  • Using '呼吸器' in a very casual, joking way. → Use '息' or '肺'.

    It sounds overly medical and can make a joke feel awkward or confusing.

小贴士

Medical Accuracy

When filling out medical forms in Japan, use 呼吸器 to describe any history of asthma or lung issues. It sounds professional and clear.

Writing '吸'

The right side of 吸 is '及' (to reach). Imagine reaching out to pull air into your mouth (the left side '口').

Pitch Accent

Keep your voice steady. Japanese is not stressed like English, so 'ko-kyu-u-ki' should flow evenly.

News Keywords

Listen for 'Kokyūki' alongside 'PM2.5' or 'Kafun' (pollen) to understand air quality warnings.

Related Systems

Learn 呼吸器 alongside 循環器 (Circulatory) and 消化器 (Digestive). They are the 'Big Three' systems in health talk.

Workplace Terms

If you see '呼吸器保護' on a sign, it means you must wear a mask. 'Hogo' means protection.

The 'In-Out' Rule

The word order is Exhale (Ko) then Inhale (Kyu). It's the opposite of the English 'Inhale/Exhale'.

Compound Power

Many medical words are made by adding 'ka' (department) or 'shikkan' (disease) to 呼吸器. Master this pattern.

Mask Culture

Understanding 呼吸器 helps you understand why Japanese people are so diligent about mask-wearing during flu season.

Biology Class

If you study biology in Japanese, you'll see this word used for gills (era) in fish as well.

记住它

记忆技巧

Think of 'KO' as air going 'Out' (like a call), 'KYŪ' as air being 'Sucked' in (like a vacuum), and 'KI' as the 'Key' organ for life.

视觉联想

Imagine a pair of lungs shaped like a giant 'K' (for Kokyūki) with a windpipe above them.

Word Web

Lungs Breath Hospital Mask Oxygen Asthma Clinic Air

挑战

Try to find the '呼吸器内科' section the next time you are in a large Japanese building or near a hospital sign.

Sino-Japanese (Kango). The term was standardized during the Meiji era as Japan modernized its medical terminology using Chinese characters to translate Western biological concepts.

原始含义： The apparatus for exhaling and inhaling.

Japonic (Sino-Japanese roots).

文化背景

Be sensitive when discussing 呼吸器疾患 (respiratory diseases) with elderly Japanese people, as it can be a serious and private health matter.

In English, 'respiratory organs' sounds very clinical. We usually just say 'lungs.' In Japanese, 呼吸器 is used slightly more broadly in semi-formal health discussions.

Medical dramas like 'Doctor-X' or 'Code Blue' frequently feature the 呼吸器外科 (Respiratory Surgery) department. Government health warnings during PM2.5 alerts. Anatomy posters in every Japanese elementary school.

In Japanese, nouns don't change for plural. 呼吸器 can refer to a single respiratory organ or the entire system of organs. Context usually implies the whole system.

Yes, but it is more formal. If you are at a doctor's office, saying '呼吸器の調子が悪い' is fine. In a casual setting with friends, '肺 (hai)' is much more natural.

It is the 'Department of Respiratory Medicine.' You go here for asthma, pneumonia, or chronic coughs. It is a very common department in Japanese hospitals.

It's 器. It has four small boxes (mouths) and a 'dog' radical (大 + dot) in the middle. It signifies a vessel or a container with many parts.

Almost. A ventilator is formally '人工呼吸器' (Jinkō Kokyūki - Artificial Respiratory Organ). In medical settings, people often shorten it to just 'Kokyūki,' so you must use context.

It is typically considered B1. While the concept is simple, the kanji and the formal usage are intermediate level.

Technically, yes. In medical terms, the 'upper respiratory tract' (上呼吸器) includes the nasal passages.

It follows the logical Sino-Japanese pattern: Ko (Exhale) + Kyū (Inhale) + Ki (Organ). It's descriptive!

It would sound very clinical and cold. For poetry, 'iki' (breath) or 'mune' (chest/heart) is usually preferred.

呼吸器 is more common in medical and daily formal use. 呼吸器官 is more academic and often used in biology textbooks.
