意識不明になる
意識不明になる in 30 Seconds
- Means 'to lose consciousness' in a serious or medical context.
- Commonly used in news reports and hospital settings for accidents.
- Formed by 'ishiki' (consciousness), 'fumei' (unknown), and 'naru' (become).
- More formal and grave than the casual 'ki o ushinau' (to pass out).
The Japanese verbal phrase 意識不明になる (ishiki fumei ni naru) is a critical expression used to describe the state of losing consciousness or falling into a coma. It is composed of three distinct parts: ishiki (consciousness), fumei (unclear/unknown), and the verb naru (to become). Literally, it translates to 'consciousness becomes unknown.' While it sounds clinical, it is the standard way to report medical emergencies, accidents, or serious health conditions in both formal news media and daily conversation when a high level of gravity is required.
- Medical Context
- In a medical or emergency setting, this phrase is used to describe a patient who is unresponsive to external stimuli. It is often paired with the duration of the state, such as 'for three days' or 'immediately after the impact.'
- News and Reporting
- Journalists use this specific phrase to describe victims of traffic accidents, natural disasters, or violent crimes when their survival is uncertain or they are in critical condition.
- Literature and Drama
- In storytelling, it heightens the drama of a scene, indicating a character's vulnerability or the severity of an injury sustained during a conflict.
事故の直後、運転手は意識不明になった。(Immediately after the accident, the driver lost consciousness.)
祖父は脳梗塞で倒れ、そのまま意識不明になった。(My grandfather collapsed from a stroke and lost consciousness just like that.)
- Grammatical Breakdown
- The phrase follows the [Noun] + [Adjective/Noun] + になる pattern. Here, 'ishiki fumei' acts as a compound noun/adjective describing the state of the subject.
Using 意識不明になる correctly requires understanding its role as a change-of-state verb. It describes the transition from being awake to being unconscious. Because it is a serious term, the surrounding grammar usually reflects a formal or descriptive tone.
- Past Tense Usage
- The most common form is '意識不明になった' (became unconscious). This is used in reporting events that have already transpired. Example: '彼は一晩中意識不明になった' (He was unconscious all night).
- Ongoing State (Te-iru)
- To describe someone who is currently unconscious, you use '意識不明になっている'. This emphasizes the continuation of the state. Example: '患者は現在も意識不明になっている' (The patient is still unconscious now).
熱中症で倒れて、意識不明になる人が増えています。(The number of people who collapse from heatstroke and lose consciousness is increasing.)
ボクサーは強烈なパンチを受けて、意識不明になった。(The boxer received a powerful punch and lost consciousness.)
- Conditional Forms
- When discussing medical risks, you might use '意識不明になると' (If/When one becomes unconscious...). Example: '大量に出血すると、意識不明になる恐れがあります' (If there is heavy bleeding, there is a fear of losing consciousness).
You will encounter 意識不明になる in several specific domains of Japanese life. It is not a word for lighthearted banter, but rather one that carries the weight of life and death situations.
- NHK News and Newspapers
- Every day, news anchors use this phrase to update the public on the status of accident victims. It is the gold standard for objective reporting on a person's lack of responsiveness.
- Hospital Waiting Rooms
- Doctors use this term when speaking to families. It is more professional and less emotionally charged than saying 'he won't wake up,' though it implies the same thing.
ニュース:山道で遭難した男性が発見されましたが、意識不明になっています。(News: A man who went missing on a mountain path was found, but he is currently unconscious.)
ドラマ:被害者は病院に運ばれましたが、意識不明になったままです。(Drama: The victim was taken to the hospital, but remains unconscious.)
Students of Japanese often confuse 意識不明になる (ishiki fumei ni naru) with related terms like 気絶する (kizetsu suru) or 倒れる (taoreru). Each has a specific nuance that must be observed to avoid sounding insensitive or inaccurate.
- Confusion with 気絶する (Kizetsu suru)
- 'Kizetsu' is synonymous with fainting. It is often used for shorter, less life-threatening episodes of loss of consciousness, such as from fear or a sudden drop in blood pressure. 'Ishiki fumei ni naru' is much more serious and suggests a medically critical state.
- Confusion with 倒れる (Taoreru)
- 'Taoreru' simply means 'to fall over' or 'to collapse.' While someone who collapses often loses consciousness, 'taoreru' only describes the physical act of falling. You might say 'He collapsed AND lost consciousness' (Taorete ishiki fumei ni natta).
間違った例:映画を見て驚いて意識不明になった。 (Incorrect: I was so surprised by the movie I lost consciousness.)
正しい例:彼は交通事故で重傷を負い、意識不明になった。(Correct: He was severely injured in a traffic accident and lost consciousness.)
Japanese has a rich vocabulary for describing states of consciousness. Depending on the level of formality and the medical severity, you may choose alternative terms.
- 気絶する (Kizetsu suru)
- Focuses on the sudden act of fainting. Commonly used in casual conversation and fiction.
- 失神する (Shisshin suru)
- A more formal medical term for fainting, often used in clinical reports or formal speech.
- 気を失う (Ki o ushinau)
- A standard, everyday phrase for 'to pass out.' It is slightly more narrative and emotional than 'ishiki fumei ni naru.'
比較:彼はショックで気を失った vs 彼は事故で意識不明になった。(Comparison: He passed out from shock vs He became unconscious due to an accident.)
How Formal Is It?
Fun Fact
The 'fumei' part of the word is the same 'mei' used in 'meisai' (details) and 'meiryo' (clear). So 'fumei' literally means 'details are not clear.'
Pronunciation Guide
- Pronouncing 'fumei' as 'fumi.'
- Putting too much stress on 'ni.'
- Forgetting the long vowel in 'fumei.'
- Pronouncing 'ishiki' like 'ichiki.'
- Making the 'r' in 'naru' too hard like an English 'r'.
Difficulty Rating
Requires knowledge of N2-level kanji like '意識' and '不明'.
Kanji for 'ishiki' (意識) are complex to write by hand.
The phrase is long but follows standard 'ni naru' patterns.
Very distinct sound, often used in news clear and slow.

Tips
Use with 'Mama'
Pair 'ishiki fumei ni natta' with 'mama' to describe someone who hasn't woken up yet. It emphasizes the continuity of the state.
Learn 'Ishiki'
Understanding 'ishiki' (consciousness) allows you to learn many related words like 'mu-ishiki' (unconscious/automatic) and 'ishiki-teki' (intentional).
Emergency Ready
This is a vital phrase for reporting emergencies. If you see someone collapse, telling a dispatcher 'ishiki fumei desu' is very effective.
News Watching
Watch NHK news to hear this phrase. It is almost always used when reporting on traffic accidents or heatstroke during summer.
Kanji Practice
The kanji for 'ishiki' (意識) are difficult. Practice the 'kokoro' (heart) radical at the bottom of both characters to remember them.
Don't Overuse
Because it's a heavy medical term, don't use it for things like 'I was so bored I lost consciousness.' It sounds too literal and strange.
Tone Matters
In Japanese, serious news is delivered with a flat, downward-drifting intonation. This phrase will often sound very grave.
Clarity over Speed
Since the phrase is 8 moras long (i-shi-ki-fu-me-i-ni-na-ru), speak it clearly so the listener understands the gravity of the situation.
Kizetsu vs Ishiki Fumei
Remember: Kizetsu = Faint (short). Ishiki Fumei = Unconscious (serious/long).
The 'Unknown' Mind
Just remember 'Fumei' = Unknown. If your mind is unknown to you, you are unconscious.
Memorize It
Mnemonic
Think of 'Ishiki' as 'I see key' (but you lost the key to your mind). 'Fumei' sounds like 'Foo-Me' (you can't see me because I'm out).
Visual Association
Imagine a lightbulb (consciousness) going dark (fumei) and falling over (naru).
Word Web
Challenge
Try to write a short news report about a fictional superhero who saves someone who became 'ishiki fumei ni naru'.
Word Origin
The phrase is a combination of Sinitic (Kango) roots. 'Ishiki' (意識) comes from Buddhist terminology referring to the mind or discernment. 'Fumei' (不明) means 'not bright' or 'unclear.'
Original meaning: Originally, 'ishiki' referred to the six types of consciousness in Buddhism. 'Fumei' meant lack of wisdom or light.
Japanese (Sino-Japanese vocabulary + Native Japanese verb).Cultural Context
Be careful when using this with family members of someone who is ill; it is a very clinical and serious term that can be upsetting.
In English, we might say 'in a coma' or 'passed out,' but 'ishiki fumei' sits right in the middle—more serious than 'passed out' but not necessarily a permanent 'coma.'
