火事 en 30 secondes
- Kaji (火事) means fire disaster.
- Used for uncontrolled, damaging fires.
- Not for campfires or stove flames.
- Common in news and emergency contexts.
- Meaning
- The Japanese word '火事' (かじ - kaji) specifically refers to a fire as a disaster or an incident, not just any fire like a campfire or a stove fire. It implies an uncontrolled blaze that causes damage or poses a threat to life and property. Think of it as a house fire, a building fire, or a wildfire that has gotten out of control.
- Usage Context
- You'll hear '火事' used in news reports about emergencies, in conversations when discussing safety precautions, or when recounting an incident. It's a common word in emergency services' vocabulary and in public safety announcements. For instance, if you hear sirens and see smoke, someone might exclaim, '火事だ！' (Kaji da! - It's a fire!). It's also used in hypothetical situations, like discussing what to do in case of a fire in your home or workplace.
- Distinguishing from Other Fires
- It's important to differentiate '火事' from other uses of the kanji '火' (hi - fire). For example, '火' can refer to the flame of a candle ('ろうそくの火' - rōsoku no hi), or a cooking fire ('焚き火' - takibi). However, '火事' specifically denotes a large, often destructive, fire. When the context is about a fire that is a problem or a danger, '火事' is the appropriate term. For instance, '料理の火' (ryōri no hi) refers to the fire for cooking, while '家の火事' (ie no kaji) refers to a house fire, which is a disaster.
- Examples in Context
- Imagine a news headline: '隣町で大きな火事が発生しました。' (Tonarimachi de ōkina kaji ga hassei shimashita. - A large fire occurred in the neighboring town.) Or in a conversation: '昨夜、近くのビルで火事があったらしいよ。' (Sakuya, chikaku no biru de kaji ga atta rashii yo. - Apparently, there was a fire in a nearby building last night.) These examples clearly show '火事' referring to a fire incident.
This is a news report about a 火事.
- Emergency Services
- Firefighters are called to '火事' to extinguish it. The fire department's primary role is to combat '火事'. When you call emergency services in Japan for a fire, you would report a '火事'.
- Safety Announcements
- Public safety announcements often include phrases like '火事の際は避難してください' (Kaji no sai wa hinan shite kudasai - Please evacuate in case of fire). This reinforces the idea of '火事' as a dangerous event requiring immediate action.
- Everyday Conversations
- In casual conversation, people might discuss a fire they witnessed or heard about. For example, '昨日のニュースで見たけど、あの火事、大変だったみたいだね。' (Kinō no nyūsu de mita kedo, ano kaji, taihen datta mitai da ne. - I saw it on the news yesterday, that fire seemed really bad.)
- Basic Sentence Structure
- '火事' often appears as the subject or object of a sentence, or as part of a phrase indicating its occurrence. Common verbs used with '火事' include '起こる' (okoru - to occur), '発生する' (hassei suru - to occur/break out), '消す' (kesu - to extinguish), and '防ぐ' (fusegu - to prevent). For example, '火事が起こりました' (Kaji ga okorimashita - A fire broke out) or '火事を消しました' (Kaji o keshimashita - They extinguished the fire).
- Describing the Location or Cause
- You can specify where the fire occurred or what caused it using particles like 'で' (de - at/in) or by using descriptive nouns. For instance, '家で火事がありました' (Ie de kaji ga arimashita - There was a fire at home) or '電気のショートが原因で火事になった' (Denki no shōto ga gen'in de kaji ni natta - The fire was caused by an electrical short).
- Expressing Concern or Action
- Sentences can express concern or actions taken regarding a fire. '火事が心配です' (Kaji ga shinpai desu - I am worried about the fire) or '火事にならないように注意しましょう' (Kaji ni naranai yō ni chūi shimashō - Let's be careful not to cause a fire). The phrase '火事だ！' (Kaji da!) is an exclamation meaning 'Fire!'
- Idiomatic and Figurative Use
- While '火事' primarily means a literal fire disaster, it can sometimes be used metaphorically to describe a chaotic or rapidly escalating situation, though this is less common than its literal meaning. For example, a very heated argument might be described with strong emotional language, but '火事' itself is rarely used in this figurative sense for arguments. Stick to its literal meaning for clarity.
We need to practice using 火事 in different sentence structures.
- News Broadcasts
- The most common place to hear '火事' is in news reports about emergencies. Headlines often feature it, such as '〇〇地区で火事、住民が避難' (Maru Maru chiku de kaji, jūmin ga hinan - Fire in XX district, residents evacuate). You'll hear it in spoken news segments detailing the extent of damage, the number of people affected, and the response from emergency services.
- Emergency Services and Public Announcements
- Firefighters, police, and other emergency personnel use '火事' frequently. Public safety announcements, whether on loudspeakers in public places, on television, or through apps, will use '火事' when issuing warnings or instructions. For example, '火事の際は、エレベーターを使用しないでください' (Kaji no sai wa, erebētā o shiyō shinaide kudasai - In case of fire, do not use the elevator).
- Conversations Among Neighbors and Friends
- If a fire occurs in a residential area, neighbors will often discuss it. You might hear: '昨日の夜、うちの近所で火事があったんだ。' (Kinō no yoru, uchi no kinjo de kaji ga attan da. - There was a fire in my neighborhood last night.) or '大丈夫だった？火事のこと聞いたよ。' (Daijōbu datta? Kaji no koto kiita yo. - Were you okay? I heard about the fire.)
- Safety Drills and Training
- In schools, workplaces, and public buildings, safety drills are conducted to prepare for emergencies like fires. During these drills, instructors might say, 'これは火事の訓練です' (Kore wa kaji no kunren desu - This is a fire drill) or '火事が発生しました！' (Kaji ga hassei shimashita! - A fire has broken out!).
- Disaster Preparedness Information
- Websites and brochures about disaster preparedness will frequently mention '火事' in the context of prevention, evacuation procedures, and emergency contacts. They might list common causes of '火事' or advice on how to prevent them.
Listen to the news for reports on 火事 to hear it in context.
- Confusing '火事' with '火' (Hi)
- The most frequent mistake is using '火' (hi) when '火事' (kaji) is intended. '火' simply means 'fire' or 'flame' and can refer to a small, controlled fire like a candle flame or a campfire. '火事' specifically means a fire disaster or incident. For example, saying 'ろうそくの火' (rōsoku no hi - candle flame) is correct, but saying 'ろうそくの火事' (rōsoku no kaji) would be incorrect and sound alarmist, implying the candle flame has turned into a dangerous fire.
- Using '火事' for Non-Disaster Fires
- Another mistake is using '火事' for any instance of fire. For example, when talking about cooking on a gas stove, you wouldn't say 'コンロの火事' (konro no kaji). Instead, you'd refer to the flame or the stove itself. '火事' implies an uncontrolled, damaging fire. Think of it as the difference between a 'fire' and a 'fire incident' or 'fire disaster'.
- Incorrect Particle Usage
- Learners might misuse particles with '火事'. For example, incorrectly using 'に' (ni) when 'で' (de) is needed to indicate the location of the fire. A correct sentence is '家で火事がありました' (Ie de kaji ga arimashita - There was a fire at home), not '家に火事がありました' (Ie ni kaji ga arimashita). The particle 'が' (ga) is typically used to mark '火事' as the subject of verbs like '起こる' (okoru - to occur) or '発生する' (hassei suru - to break out).
- Over-reliance on Direct Translation
- Directly translating English phrases can lead to errors. For instance, while in English we might say 'the fire spread,' in Japanese, when referring to a disaster fire, it's more natural to say '火事が広がった' (kaji ga hirogatta). Thinking about the specific nuance of '火事' as a disaster helps avoid literal translation pitfalls.
Avoid confusing '火' with '火事' in your Japanese.
- 火 (Hi) - Fire, Flame
- '火' is the most basic word for fire. It can refer to a flame, heat, or a light source. It's used for controlled fires like a campfire ('焚き火' - takibi), a stove flame ('コンロの火' - konro no hi), or the flame of a candle ('ろうそくの火' - rōsoku no hi). It lacks the sense of disaster inherent in '火事'. For example, '火が消えた' (Hi ga kieta - The fire went out) could refer to a candle flame or a campfire.
- 炎 (Honō) - Flame
- '炎' specifically refers to the visible part of a fire, the flame itself. It's often used poetically or to describe the appearance of fire, like '燃え盛る炎' (moesakaru honō - blazing flames). While related to '火事', '炎' focuses on the visual aspect of fire, not the event of a disaster. A house fire ('火事') will have '炎'.
- 燃焼 (Nenshō) - Combustion
- '燃焼' is a more technical term referring to the process of burning or combustion. It's used in scientific or industrial contexts. For example, '不完全燃焼' (fukanzen nenshō - incomplete combustion) is a cause of carbon monoxide poisoning. While a '火事' involves '燃焼', '燃焼' itself doesn't imply a disaster; it's the scientific process.
- 火災 (Kasai) - Fire (disaster)
- '火災' is a very close synonym to '火事' and is often used interchangeably, especially in formal contexts like news reports, legal documents, or official announcements. It also means 'fire disaster'. For instance, '火災報知機' (kasai hōchiki) means 'fire alarm'. While '火事' is more common in everyday speech, '火災' is equally valid and sometimes preferred in more serious or official contexts. The kanji composition (火 - fire, 災 - disaster) clearly emphasizes the disaster aspect.
While '火災' is similar, '火事' is more common in casual conversation.
How Formal Is It?
Le savais-tu ?
While '火事' is the common word for a fire disaster, the kanji '事' itself is used in many other words to denote an event or matter, such as '大事' (daiji - important matter) or '用事' (yōji - errand/business). The combination clearly points to an event involving fire.
Guide de prononciation
- Pronouncing 'ji' as 'zee' or 'she'.
- Adding an extra syllable.
- Misplacing the stress.
- Confusing it with similar-sounding words.
Niveau de difficulté
The word '火事' is relatively straightforward in meaning. However, understanding its nuances and distinguishing it from '火' or '火災' requires careful attention to context and usage, which can be challenging for beginners.

彼の言葉が私の心に火を点けた。 (Kare no kotoba ga watashi no kokoro ni hi o tsuketa. - His words ignited a fire in my heart.)
Common— Where there's smoke, there's fire. It means that if there are rumors or signs of trouble, there's likely some truth to them.
あの噂が流れているということは、火のない所に煙は立たぬ、何かあるのだろう。 (Ano uwasa ga nagarete iru to iu koto wa, hi no nai tokoro ni kemuri wa tatanu, nanika aru no darō. - The fact that those rumors are circulating suggests there's smoke where there's no fire; something must be going on.)
Proverbial— To be exposed to danger or hardship; to suffer the consequences of a chaotic situation. Similar to '火の粉が舞う', it implies being in a risky or volatile environment.
彼はその政治闘争で火の粉を浴びることになった。 (Kare wa sono seiji tōsō de hi no ko o abiru koto ni natta. - He ended up exposed to danger in that political struggle.)
FigurativeFacile à confondre
Both relate to fire.
'火' is the general term for fire or flame, like a campfire or a candle flame. '火事' specifically denotes a fire as a disaster or an uncontrolled incident causing damage. You wouldn't say 'ろうそくの火事' (candle fire disaster); you'd say 'ろうそくの火' (candle flame).
キャンプの火は暖かかった。(Kyanpu no hi wa atatakakatta. - The campfire was warm.) vs. 家が火事になった。(Ie ga kaji ni natta. - The house caught fire/had a fire disaster.)
Both are related to fire.
'炎' (honō) refers to the visible flame itself. '火事' (kaji) refers to the entire event of a fire disaster. You can see flames ('炎') during a fire disaster ('火事'), but '炎' is just one aspect of it.
炎が大きく燃え上がった。(Honō ga ōkiku moeagatta. - The flames flared up greatly.) vs. 火事が起きて、多くの人が避難した。(Kaji ga okite, ōku no hito ga hinan shita. - A fire broke out, and many people evacuated.)
Both mean 'fire disaster'.
'火事' is more common in everyday spoken Japanese and informal contexts. '火災' is more formal and is typically used in news reports, official documents, and technical contexts. While interchangeable in some situations, '火事' feels more immediate and conversational.
隣町で火事があったらしい。(Tonarimachi de kaji ga atta rashii. - Apparently, there was a fire in the neighboring town.) vs. 火災発生に関する速報。(Kasai hassei ni kansuru sokuhō. - Breaking news regarding the occurrence of a fire.)
They are related actions concerning fire.
'消火' (shōka) means 'firefighting' or 'extinguishing a fire'. It is the action taken to combat a '火事'. '火事' is the event itself (the disaster), while '消火' is the response to it.
消防士たちが火事を消した。(Shōbōshi-tachi ga kaji o keshita. - The firefighters extinguished the fire.)
Both relate to the origin of fire.
'火元' (himoto) refers to the specific source or origin where a fire started. '火事' is the overall disaster. You investigate the '火元' to understand the cause of the '火事'.
火事の原因は火元にあった。(Kaji no gen'in wa himoto ni atta. - The cause of the fire was at its origin.)

Mémorise-le
Moyen mnémotechnique
Imagine a burning house (火) with a lot of 'chaos' (similar sound to 'kaji'). The 'chaos' is the disaster. So, '火' + 'chaos' = 'kaji' (fire disaster).

Word Web
Défi

Origine du mot
The word '火事' (kaji) is a compound word formed from '火' (hi - fire) and the suffix '事' (koto - matter, affair, incident). The suffix '事' is often used to turn a noun into a concept or event.
Sens originel : Literally means 'fire matter' or 'fire incident'.
JaponicContexte culturel
Discussing '火事' should be done with sensitivity, especially if referring to recent or ongoing events where people may have suffered loss or trauma. When teaching, focus on the vocabulary and its usage in a neutral context, emphasizing safety and prevention.
In English-speaking cultures, 'fire' is a general term, but specific terms like 'blaze,' 'inferno,' or 'conflagration' denote larger, more destructive fires. 'Fire' itself can refer to a disaster, but also to a campfire or a fireplace.

Questions fréquentes
10 questionsThe main difference lies in the implication of disaster. '火' (hi) is a general term for fire or flame, which can be small and controlled, like a candle flame or a campfire. '火事' (kaji) specifically refers to a fire as a disaster or an uncontrolled incident that causes damage or poses a threat. For example, 'ろうそくの火' (rōsoku no hi) is a candle flame, but '家が火事になった' (ie ga kaji ni natta) means a house caught fire and became a disaster.
'火事' (kaji) is generally more common in everyday spoken Japanese and informal conversations. '火災' (kasai) is a more formal term, often used in news reports, official documents, and technical contexts related to fire disasters. While they both mean 'fire disaster', '火事' feels more immediate and conversational.
No, '火事' (kaji) is not used for small, controlled fires like a stove fire or a cooking fire. It specifically denotes a fire that is an emergency or a disaster, implying uncontrolled burning and potential damage. For a stove fire, you would refer to the flame ('火') or the stove itself.
In case of a '火事', the immediate reaction is to ensure safety, which usually involves evacuation. Public announcements and safety drills emphasize staying calm and following evacuation routes. The phrase '火事だ！' (Kaji da! - Fire!) is an urgent exclamation used to alert others.
Common causes include electrical shorts, unattended cooking fires, smoking materials, and faulty heating equipment. Prevention measures like regular checks of electrical appliances and careful handling of open flames are highly emphasized.
While its primary meaning is a literal fire disaster, '火事' can sometimes be used metaphorically to describe a chaotic or rapidly escalating situation, although this is less common than its literal meaning. However, for clarity, it's best to stick to its literal meaning, especially when learning.
'火事' (kaji) is the fire disaster itself. '火の粉' (hi no ko) refers to sparks or embers that fly from a fire. It's a component of a fire, not the entire disaster.
A firefighter is called '消防士' (shōbōshi). The word '消防' (shōbō) itself means firefighting or fire department.
If you see a '火事', your priority is safety. Alert others by shouting '火事だ！' (Kaji da!), call the fire department (119 in Japan), and evacuate if necessary. Do not try to fight a large fire yourself.
While '火事' is general for disaster fires, context can specify. For example, '山火事' (yamakaji) is a wildfire, and '家事' (kaji, different kanji) means housework, which can be confused phonetically but has a completely different meaning. More technical terms exist for specific combustion processes.
