鼻水が出る

The Japanese phrase 鼻水が出る (hanamizu ga deru) is the standard way to express that one has a runny nose. Linguistically, it is a very literal construction. The word 鼻 (hana) means 'nose', and 水 (mizu) means 'water'. Combined, 鼻水 (hanamizu) refers to nasal mucus. The verb 出る (deru) means 'to come out' or 'to exit'. Therefore, the phrase literally translates to 'nose water comes out'. This is a neutral, everyday expression used by all age groups in both casual and semi-formal contexts. Whether you are talking to a friend about your allergies or explaining your symptoms to a doctor, this is the go-to phrase. Understanding the mechanics of the verb 'deru' is essential here; it is an intransitive verb, meaning the mucus is the subject performing the action of exiting, which is why the particle が (ga) is used to mark it.

Literal Meaning

Nasal water exits/comes out.

Common Usage

Used when suffering from a cold, hay fever (kafunsho), or reaction to cold air.

Social Context

Acceptable in schools, workplaces, and medical settings. Not considered overly graphic.

In Japan, discussing minor physical ailments like a runny nose is quite common, especially during the changing of seasons or the high-pollen spring months. You will often hear people apologizing for their condition if they are sniffling in a meeting or a quiet classroom. The phrase is often paired with symptoms like sneezing (kushami) or a cough (seki). It is also important to note that in Japanese culture, blowing your nose loudly in public is sometimes frowned upon; instead, many people prefer to 'sniffle' or step away to a private area. Using this phrase helps explain why you might be stepping out or why you are wearing a mask, which is a common sight in Japan for those with runny noses.

When the symptoms are particularly bad, you might hear the variation 鼻水が止まらない (hanamizu ga tomaranai), meaning 'the runny nose won't stop'. This emphasizes the persistence and annoyance of the condition. In a medical setting, a doctor might ask 'Itsu kara hanamizu ga demasu ka?' (Since when has your nose been running?). This phrase is the building block for discussing respiratory health. It is also used metaphorically in very rare, specific slang contexts, but for a B1 learner, focusing on the medical and physical health application is the priority. The phrase is also used for children, though parents might use the more 'cute' or simplified term 'hana' (nose) as in 'hana deteru yo' (your nose is running/leaking).

Associated Symptoms

くしゃみ (Kushami - Sneeze), 鼻詰まり (Hanazumari - Stuffy nose), 熱 (Netsu - Fever).

Furthermore, the phrase can be used in the progressive form 鼻水が出ている (hanamizu ga dete iru) to describe a current, ongoing state, often used when pointing out the condition in someone else (like a child) or describing a persistent symptom over a period of time. In the winter, you might hear people say 寒くて鼻水が出る (samukute hanamizu ga deru), which refers to the common phenomenon of the nose running due to cold temperatures rather than a virus or allergy. This versatility makes it one of the most practical phrases to learn for daily life in Japan, especially if you have sensitive sinuses or are prone to the common cold.

Using 鼻水が出る (hanamizu ga deru) correctly involves understanding both the grammatical structure and the appropriate level of politeness. As an intransitive verb phrase, the subject (hanamizu) is followed by the particle が (ga). You should avoid using を (wo) because 'deru' describes a spontaneous occurrence. In terms of conjugation, you will most commonly use the dictionary form (deru), the polite form (demasu), or the past forms (deta/demashita). If you want to say your nose started running, you would use the past tense: 鼻水が出た (hanamizu ga deta).

Polite Form (Desu/Masu)

鼻水が出ます (Hanamizu ga demasu) - Used with teachers, doctors, or strangers.

Casual Form

鼻水が出る (Hanamizu ga deru) - Used with friends and family.

Negative Form

鼻水が出ない (Hanamizu ga denai) - Used when a nose is dry or perhaps congested but not running.

When explaining a reason for the runny nose, you can use the 〜て (te) form or the 〜ので (node) / 〜から (kara) structures. For example, 'Samukute hanamizu ga demasu' (Because it's cold, my nose runs). If you are describing a continuous state, the 〜ている (te-iru) form is appropriate. 'Zutto hanamizu ga dete imasu' means 'My nose has been running continuously'. This is particularly useful for medical histories. You can also add adverbs to modify the intensity, such as だらだら (dara-dara), which describes a continuous dripping sensation.

Another important grammatical point is the use of potential forms or expressions of inability. If you want to say you can't stop your nose from running, you would say 鼻水が止まらない (hanamizu ga tomaranai). While 'deru' itself isn't usually put into the potential 'dereru' form in this context, the concept of 'can't stop' is the standard way to express lack of control. In pediatric contexts, you might hear the causative form 出させる (dasaseru) if a doctor is asking a parent to make the child's nose run (though rare), but the focus for learners should remain on the intransitive 'deru'.

Question Form

鼻水は出ますか？ (Hanamizu wa demasu ka?) - 'Do you have a runny nose?' (Topic marker 'wa' is common in clinical questioning).

Finally, consider the combination with 〜そうだ (sou da) for appearance. 'Hanamizu ga desou' means 'It feels like my nose is about to run' or 'I feel a runny nose coming on'. This is a very natural way to express a pre-symptomatic feeling. Mastering these variations allows you to communicate your physical state with nuance and accuracy, ensuring you get the right medicine or sympathy from those around you. Remember that 'hanamizu' is the subject, so keep that が (ga) particle handy!

You will encounter 鼻水が出る (hanamizu ga deru) in a variety of real-world settings in Japan. One of the most common places is the 耳鼻咽喉科 (jibi-inkouka), or the ENT (Ear, Nose, and Throat) clinic. Doctors and nurses will use this phrase constantly when diagnosing patients. You'll hear it in waiting rooms, in patient-doctor consultations, and even on medical intake forms. For example, a nurse might ask, 'Hanamizu wa demasu ka?' (Is your nose running?) as part of a routine check-up for a cold. Understanding this phrase is essential for navigating the Japanese healthcare system.

Another frequent context is during the spring, which is 花粉症 (kafunsho) or hay fever season in Japan. Japan has a high density of cedar (sugi) and cypress (hinoki) trees, leading to massive amounts of pollen. During this time, television news reports and weather forecasts will frequently mention 'hanamizu' in relation to pollen counts. You will hear people in the office or at school complaining about their symptoms. It becomes a major topic of small talk: 'Kotoshi wa hanamizu ga hidoi desu ne' (The runny nose is terrible this year, isn't it?). In this context, the phrase is a shared social experience for millions of Japanese people.

In schools and households, the phrase is used by parents and teachers to check on children's health. A teacher might notice a student sniffling and ask, 'Hanamizu ga deteru kedo, daijoubu?' (Your nose is running, are you okay?). Parents will often say to their children, 'Hanamizu ga deteru yo, kami nasai' (Your nose is running, blow it). Because it is a simple and direct phrase, it is one of the first health-related expressions children learn. You'll also hear it in animated shows (anime) or dramas when a character is sick, often depicted with a single bubble coming out of the nose (a common visual trope for sleeping or being sick).

Television/News

Pollen forecasts often list 'hanamizu' as a primary symptom to watch out for.

Drugstores

Labels like '鼻水・鼻づまりに' (For runny and stuffy noses) are common on over-the-counter drugs.

Lastly, you might hear it in casual conversations during winter activities, like skiing or ice skating. The cold air naturally causes the nose to run, and friends will often point it out to each other or complain about it themselves. 'Samusugite hanamizu ga deta!' (It's so cold my nose started running!). In all these scenarios, the phrase remains consistent, making it a highly reliable and recognizable part of the Japanese linguistic landscape. Whether in the sterile environment of a clinic or the casual atmosphere of a ski slope, 'hanamizu ga deru' is the universal way to describe this pesky physical condition.

One of the most frequent mistakes English speakers make when using 鼻水が出る (hanamizu ga deru) is using the wrong particle. In English, we say 'my nose is running', which might tempt a learner to say 'hana ga hashiru' (literally: the nose runs/jogs). However, in Japanese, 走る (hashiru) is strictly for physical running with legs. Using it for a nose will sound nonsensical or like a joke. The correct verb is always 出る (deru). Another particle error is using を (wo) instead of が (ga). Since 'deru' is an intransitive verb (the action happens to the subject), using 'wo' would imply you are intentionally 'outputting' your nasal mucus, which is grammatically incorrect and contextually weird.

Incorrect

鼻水を出る (Hanamizu wo deru) - Wrong particle.

Incorrect

鼻が走る (Hana ga hashiru) - Literal translation of 'nose runs'.

Correct

鼻水が出る (Hanamizu ga deru) - The standard expression.

Another common error involves confusing 出る (deru) with 出す (dasu). While 'deru' is 'to come out', 'dasu' is the transitive 'to put out' or 'to take out'. If you say 'hanamizu wo dasu', it sounds like you are actively producing it or showing it to someone, which is rarely what you mean to say. Stick to 'deru' for the symptom itself. Additionally, learners sometimes forget to use the 〜ている (te-iru) form when describing a state. If your nose is currently running and you want to emphasize the ongoing nature, 'hanamizu ga dete iru' is more natural than the simple 'deru', which can sometimes sound like a general habit or a future event.

Confusion also arises between 'runny nose' and 'stuffy nose'. Learners often use 'hanamizu ga deru' when they actually mean their nose is blocked. For a blocked or stuffy nose, the correct term is 鼻が詰まる (hana ga tsumaru). Using 'deru' when your nose is blocked will confuse the listener, especially a pharmacist or doctor. Furthermore, when talking about blowing your nose, the verb is かむ (kamu). Some learners try to use 'fuku' (to wipe), which is okay for the outside of the nose, but 'kamu' is the specific verb for blowing. 'Hanamizu wo kamu' is the correct pairing.

Finally, be careful with the politeness levels. While 'hanamizu ga deru' is neutral, in a professional setting or when speaking to a superior, adding んです (n desu) or using the polite 出ます (demasu) is important. Simply saying 'hanamizu ga deru' to a boss might sound a bit too blunt or childish. Also, avoid using the word 鼻汁 (bijuu) in casual conversation; this is a technical medical term (nasal discharge) and sounds very clinical. Stick to 'hanamizu' for all daily interactions to avoid sounding like a textbook or a medical report.

While 鼻水が出る (hanamizu ga deru) is the most common phrase, there are several related terms and alternatives that can provide more specific meaning. Understanding these will help you describe your symptoms more accurately. The most direct counterpart is 鼻が詰まる (hana ga tsumaru), which means 'to have a stuffy/blocked nose'. Often, people suffer from both, leading to the phrase 鼻水と鼻詰まり (hanamizu to hanazumari). If the mucus is specifically 'dripping' rather than just 'running', you can use the onomatopoeic だらだら (dara-dara) as in 鼻水がだらだら出る.

鼻が詰まる (Hana ga tsumaru)

To have a stuffy or congested nose. Use this when you can't breathe through your nose.

鼻水をかむ (Hanamizu wo kamu)

To blow one's nose. This is the action you take to deal with a runny nose.

鼻をすする (Hana wo susuru)

To sniffle. Common in Japan as an alternative to blowing one's nose in public.

In a medical or formal context, you might encounter the word 鼻汁 (bijuu). This is the clinical term for nasal discharge. While you wouldn't use this in casual conversation, you will see it on medical forms or in anatomical diagrams. Another related term is 青鼻 (aobana), which literally means 'blue nose' but refers to thick, yellowish-green mucus often associated with an infection. This is more common in casual or slightly older speech, or when parents describe their children's symptoms. For a very watery, clear runny nose (typical of allergies), you might use 水っぽい鼻水 (mizuppoi hanamizu).

If you are looking for a more general way to say you are sick, you can say 鼻の調子が悪い (hana no choushi ga warui), meaning 'my nose is in bad condition'. This covers everything from running to stuffiness to itching. For those with allergies, 鼻がムズムズする (hana ga muzumuzu suru) is a great phrase to describe that itchy, 'about to sneeze' feeling. Comparing these options: 'hanamizu ga deru' is the symptom, 'hana ga tsumaru' is the blockage, 'hana wo kamu' is the action, and 'bijuu' is the medical term. Mastering this cluster of vocabulary will make you much more proficient in discussing health and comfort in Japanese.

鼻水が止まる (Hanamizu ga tomaru)

The runny nose stops. (Antonym/Result).
