When you feel very, very tired, like after a long day of work or a big exercise, that feeling is 疲労 (hirō). It’s more than just being a little sleepy; it means your body and mind are really worn out. You might hear people talk about 疲労回復 (hirō kaifuku), which means recovering from this tiredness. So, if you’ve had a tough day, you're probably feeling some 疲労!
When you feel super tired, like after a long day of work or studying, that feeling is called 疲労 (hirō) in Japanese. It's more than just being a little sleepy; it's a deep sense of tiredness that makes you want to rest. You might hear people use this word when they are talking about needing a break or recovering from something strenuous. It's a common word to describe that worn-out feeling.
When discussing advanced topics or formal situations, it's helpful to know more precise vocabulary. 疲労 (hirō) is a more formal and clinical term for fatigue or exhaustion compared to the more common 疲れ (tsukare).
You'll often encounter 疲労 in medical contexts, scientific reports, or when talking about chronic conditions. For example, a doctor might diagnose someone with 慢性疲労 (mansei hirō), meaning chronic fatigue. It carries a more serious nuance than just feeling tired after a long day.
Understanding this distinction allows for more accurate and nuanced expression, especially when the severity or cause of the tiredness is important. While 疲れ is perfectly fine for everyday situations, 疲労 is the word to reach for when precision matters.
疲労 in 30 Seconds
- 疲労 means fatigue or exhaustion.
- It's often used for physical or mental tiredness.
- Common in medical or formal contexts.
Let's talk about a word you'll hear a lot, especially in busy Japan: 疲労 (hirō). This isn't just about feeling a little tired. This word is more serious. Think of it as fatigue, exhaustion, or being utterly worn out. It's the kind of tired that sticks with you, physically or mentally.
§ What is 疲労 (hirō)?
- DEFINITION
- Fatigue, exhaustion. It describes a state of extreme tiredness, often prolonged, that goes beyond simple sleepiness.
You use 疲労 when someone is genuinely run down. It's not for when you just need a nap. It's for when you've been working too much, studying too hard, or dealing with a lot of stress. It can be physical 疲労 (肉体疲労 - nikutai hirō) or mental 疲労 (精神疲労 - seishin hirō). Both are common uses.
§ When do people use it?
You'll hear 疲労 in various situations:
Workplace: If someone is working long hours, especially in a physically demanding job or a high-stress office environment, they might experience 疲労.
長時間の労働で疲労が蓄積している。
- HINT
- Fatigue from long hours of work has accumulated.
Healthcare: Doctors or nurses might use this term to describe a patient's condition, especially if the patient is suffering from chronic 疲労 or 疲労 caused by an illness.
患者は全身疲労を訴えている。
- HINT
- The patient complains of general fatigue.
Sports: Athletes often talk about 疲労 after intense training or competition.
試合後の選手の疲労は相当なものだった。
- HINT
- The fatigue of the athletes after the match was considerable.
Daily Life (more serious contexts): While you'd typically use 疲れ (tsukare) for everyday tiredness, 疲労 can come up if someone is truly struggling with exhaustion due to life circumstances.
育児の疲労で、なかなか自分の時間が取れない。
- HINT
- Due to the fatigue of childcare, I can't really find time for myself.
Remember, 疲労 often suggests a need for proper rest or even medical attention. It's a stronger word than just 'tired.'
§ Don't confuse 疲労 with just 'tired'
Many beginners learning Japanese see 疲労 and immediately think 'tired'. While it does relate to being tired, 疲労 is much stronger. It means 'fatigue' or 'exhaustion'. Think of it as a deeper, more profound state than just feeling a little sleepy or run down. You wouldn't use 疲労 after a short walk; you'd use it after a marathon or a week of sleepless nights.
§ Using 疲労 as a verb
Another common mistake is trying to use 疲労 directly as a verb. 疲労 is a noun. You can't just say *疲労する* in the same way you might say *疲れる* (tsukareru - to get tired). To use 疲労 in a verbal sense, you usually combine it with other verbs like 蓄積する (chikuseki suru - to accumulate) or 解消する (kaishō suru - to relieve/resolve).
- DEFINITION
- To accumulate fatigue/exhaustion
最近、疲労が蓄積している。(Saikin, hirō ga chikuseki shiteiru.)
Hint: Lately, fatigue is accumulating.
- DEFINITION
- To relieve fatigue/exhaustion
温泉で疲労を解消したい。(Onsen de hirō o kaishō shitai.)
Hint: I want to relieve my fatigue at a hot spring.
§ Misplacing 疲労 in sentences
Because 疲労 is a noun, its placement in a sentence needs to follow noun grammar rules. It often acts as the subject or object of a sentence, or modifies another noun. Don't try to use it as an adjective directly preceding a noun, like you might with 'tired' in English ('tired feeling'). For example, you wouldn't say *疲労な体* (hirō na karada). Instead, you'd say something like *疲労による体* (hirō ni yoru karada - a body due to fatigue) or *疲労した体* (hirō shita karada - a fatigued body, using the verb form).
Incorrect: 彼は疲労です。(Kare wa hirō desu.) - He is fatigue. (Grammatically incorrect, like saying 'He is exhaustion.')
Correct: 彼は疲労している。(Kare wa hirō shiteiru.) - He is fatigued/exhausted. (Using the verb form 疲労する.)
Correct: 疲労がピークに達した。(Hirō ga pīku ni tasshita.) - His fatigue reached its peak. (疲労 as the subject.)
§ Overusing 疲労
While 疲労 is a useful word, it's not always the best choice for every situation where someone is tired. If someone is just a bit tired from a normal day, using 疲労 might sound overly dramatic. It implies a serious level of weariness. Think about the context and the severity of the tiredness. For everyday tiredness, stick to 疲れた (tsukareta) or しんどい (shindoi - weary/tough, informal).
By understanding these common pitfalls, you can use 疲労 more accurately and naturally in your Japanese conversations and writing. Remember its nuance as 'fatigue' or 'exhaustion' rather than simple 'tiredness', and pay attention to its grammatical role as a noun.
Understanding the nuances between similar Japanese words can be tricky, especially when they all seem to mean something like 'tiredness.' This section will help you differentiate 疲労 (hirō) from other common words for feeling tired and guide you on when to use each one.
§ 疲労 (hirō): Formal and Medical Fatigue
As you've learned, 疲労 (hirō) is a more formal and often more serious term for fatigue or exhaustion. Think of it in contexts where you might use 'fatigue' in English – medical reports, scientific discussions, or when describing a deep, lasting tiredness.
- DEFINITION
- 疲労 (hirō): Fatigue, exhaustion (often more severe, prolonged, or formal).
長時間の労働で疲労が蓄積した。
Translation hint: Long hours of work led to accumulated fatigue.
医師は彼の疲労の原因を調査している。
Translation hint: The doctor is investigating the cause of his fatigue.
§ 疲れる (tsukareru): General Tiredness (Verb)
This is the most common and versatile way to express 'to be tired' or 'to get tired.' It's a verb, and you'll hear it in everyday conversations far more often than 疲労 (hirō).
- DEFINITION
- 疲れる (tsukareru): To be tired, to get tired (general, everyday usage).
今日はとても疲れた。
Translation hint: I'm very tired today.
歩きすぎて足が疲れた。
Translation hint: My legs got tired from walking too much.
§ くたびれる (kutabireru): Worn Out, Exhausted (Colloquial Verb)
くたびれる (kutabireru) is another verb for 'to get tired,' but it often carries a stronger sense of being 'worn out' or 'exhausted' from effort or long duration. It's more colloquial than 疲れる and can imply a greater degree of physical strain.
- DEFINITION
- くたびれる (kutabireru): To be worn out, to be exhausted (colloquial, often from physical effort).
一日中歩き回って、もうくたびれた。
Translation hint: After walking around all day, I'm completely worn out.
古い服がもうくたびれている。
Translation hint: These old clothes are already worn out.
§ 疲労困憊 (hirōkonpai): Utter Exhaustion (Compound Noun)
This is a stronger, more emphatic noun than 疲労 (hirō). It means 'utter exhaustion' or 'complete fatigue.' Use it when you want to emphasize a very high level of tiredness, often to the point of collapse.
- DEFINITION
- 疲労困憊 (hirōkonpai): Utter exhaustion, complete fatigue.
マラソンの後、選手たちは皆疲労困憊だった。
Translation hint: After the marathon, all the athletes were utterly exhausted.
§ When to use 疲労 (hirō)
- Formal situations: Medical contexts, news reports, official documents.
- Describing a condition: When talking about chronic fatigue syndrome (慢性疲労症候群 - mansei hirō shōkōgun) or accumulated fatigue.
- More severe or prolonged tiredness: When 'tiredness' feels too light for the situation.
In casual, daily conversation, you will most often use 疲れる (tsukareru) to say 'I'm tired.' Use 疲労 (hirō) when you need to convey a more serious, formal, or long-term sense of fatigue.
Pronunciation Guide
- Pronouncing the 'o' as a long 'oh' sound instead of a short 'o' like in 'go'.

How to Use It
While 疲労 (hirō) means fatigue or exhaustion, it's generally used in more formal contexts or when describing a more severe, pervasive tiredness rather than just being a little tired after a long day.
For everyday tiredness, you're more likely to hear or use 疲れ (tsukare), which is a more general term for tiredness or fatigue. 疲れ can be used for both physical and mental tiredness.
You might see 疲労 in medical contexts, news reports about widespread exhaustion, or in self-help books discussing burnout. For instance, a doctor might diagnose someone with 慢性疲労 (mansei hirō), meaning chronic fatigue.
When talking about yourself feeling tired after a normal day, stick with 疲れた (tsukareta) or 疲れています (tsukarete imasu).
A common mistake is using 疲労 in casual conversation when you simply mean 'I'm tired.' For example, saying 「今日は疲労しました」 (Kyō wa hirō shimashita) to mean 'I'm tired today' would sound overly formal and a bit unnatural. Instead, say 「今日は疲れました」 (Kyō wa tsukaremashita).
Another mistake is confusing it with terms for drowsiness or sleepiness. While exhaustion can lead to sleepiness, 疲労 specifically refers to the state of being fatigued, not necessarily feeling sleepy. For sleepiness, you'd use words like 眠い (nemui).
Tips
Kanji Meaning
The kanji for 疲労 (hirō) are 疲 (tsuka, meaning tired or fatigued) and 労 (rō, meaning labor or trouble). Understanding these individual meanings helps grasp the overall sense of exhaustion.
Common Usage
疲労 is often used in more formal or medical contexts than simpler terms like 疲れた (tsukareta), which is a common way to say 'I'm tired' in everyday conversation. Think of it as 'fatigue' rather than just 'tiredness'.
Verbs with Hirō
You'll often see 疲労 combined with verbs like 疲労する (hirō suru) to mean 'to become fatigued' or 'to tire out'. For example, 長時間の労働で疲労する (chōjikan no rōdō de hirō suru - to become fatigued from long hours of work).
Common Phrases
Look for phrases like 疲労回復 (hirō kaifuku - recovery from fatigue) or 疲労困憊 (hirō konpai - utter exhaustion). These are fixed expressions where 疲労 is key.
Differentiating from Tsukareta
While 疲れた is suitable for 'I'm tired' after a long day, 疲労 is more appropriate when discussing a deeper, more chronic state of exhaustion, or in professional settings. For instance, '精神的疲労' (seishinteki hirō - mental fatigue).
Reading in Context
Pay attention to the context. In a news report about overwork, 疲労 is more likely to appear than 疲れた. In a casual conversation, 疲れた is more natural. This helps you understand the formality.
Don't Overuse
Avoid using 疲労 in casual conversation where 疲れた would suffice. It can sound overly formal or even dramatic. Use it when you genuinely mean fatigue or exhaustion.
Associated Nouns
You'll often see 疲労 combined with other nouns to specify the type of fatigue. For example, 肉体疲労 (nikutai hirō - physical fatigue) or 目の疲労 (me no hirō - eye strain/fatigue).
Adjective Form
While 疲労 is a noun, you can describe something as causing fatigue using a slightly different structure. For example, 疲労の原因 (hirō no gen'in - cause of fatigue).
Practice with Sentences
The best way to get comfortable is to see it in sentences. For example: 過労は疲労につながります (Karō wa hirō ni tsunagarimasu - Overwork leads to fatigue). This reinforces its meaning and usage.
Memorize It
Mnemonic
Imagine a **hero** (sounds like hirō) who is completely exhausted after saving the world. He's suffering from extreme **fatigue**.
Visual Association
Picture a person collapsed on a 'hi-ro' (high road), completely worn out and suffering from **fatigue**.
Word Web
Challenge
Describe a time you felt extreme **fatigue** using 疲労 in a sentence. For example: 長時間の仕事で疲労を感じました。(Chōjikan no shigoto de hirō o kanjimashita.) - I felt **fatigue** from long hours of work.
Frequently Asked Questions
10 questions疲労 is pronounced 'hirō'. The 'hi' is like in 'hit', and 'rō' is like 'row' with a long 'o' sound. The accent is on the 'ro'.
Both 疲労 and 疲れ mean 'fatigue' or 'tiredness'. However, 疲労 (hirō) often implies a more profound or chronic state of exhaustion, sometimes even medical fatigue. 疲れ (tsukare) is more general and can refer to everyday tiredness from work or exercise.

- 疲労困憊 (hirō konpai): Utter exhaustion, completely worn out.
- 疲労回復 (hirō kaifuku): Recovery from fatigue.

While it's understood, 疲れ (tsukare) is much more common in daily, casual conversation to express general tiredness. 疲労 is more formal and often used in written contexts, news, or when discussing more serious levels of fatigue.
You wouldn't typically say 'I'm 疲労'. Instead, you'd use a verb form or an adjective. For example, '疲労している' (hirō shiteiru) means 'I am fatigued' (more formal), or more commonly, '疲れています' (tsukareteimasu) or '疲れた' (tsukareta) meaning 'I'm tired'.
Yes, you can describe different levels. For instance, you could say 軽い疲労 (karui hirō) for 'light fatigue' or 重い疲労 (omoi hirō) for 'heavy/severe fatigue'.
The first kanji, 疲 (tsukare), means 'tired' or 'exhausted'. The second kanji, 労 (rō), means 'labor' or 'toil'. Together, they literally convey 'exhausted from labor', leading to the meaning of 'fatigue'.
Use 疲労 when you want to sound more formal, or when describing a more significant or prolonged state of exhaustion, perhaps in a medical or professional context. For everyday 'I'm tired', stick with 疲れ.
Yes, absolutely. 疲労 can be a symptom of illness, stress, or overwork. You might see it used in phrases like 疲労の症状 (hirō no shōjō - symptoms of fatigue).
