疲れやすい

The Japanese term 疲れやすい (tsukare-yasui) is a compound adjective that describes a specific physical or psychological state where one is prone to fatigue or easily exhausted. Morphologically, it is constructed from the continuative form (ren'youkei) of the Ichidan verb tsukareru (疲れる, to get tired) and the auxiliary adjective yasui (やすい), which denotes ease of action or a high probability of a certain state occurring. In the context of Japanese linguistics, the suffix -yasui transforms the verb into an i-adjective that characterizes the subject's inherent nature or current condition rather than a temporary state of being. While English speakers might simply say 'I'm tired,' tsukare-yasui implies a recurring tendency or a change in one's constitution. It is a vital word for discussing health, aging, and lifestyle balance in Japan, a society where physical endurance and 'ganbaru' (persisting) are often highly valued.

Compound I-Adjective (Verb Stem + Yasui)

Core Nuance

Describes a predisposition or susceptibility to exhaustion rather than the immediate feeling of being tired.

When a Japanese person uses this word, they are often expressing a concern about their health or stamina. For instance, after a long period of overwork or during the humid summer months (known for causing 'natsubate'), one might notice that tasks which were previously easy now feel draining. This transition is perfectly captured by tsukare-yasui. It is also frequently used in medical contexts. If you visit a 'naika' (internal medicine clinic) in Japan, the doctor might ask if you have been feeling 'tsukare-yasui' lately to check for underlying conditions like anemia, thyroid issues, or chronic stress. It is a word that bridges the gap between casual observation and clinical symptom reporting.

The cultural significance of stamina in Japan cannot be overstated. The concept of tairyoku (physical strength/stamina) is a common topic of conversation. Using tsukare-yasui is a socially acceptable way to acknowledge one's limits without appearing lazy. It shifts the focus from a lack of will to a physical reality. Furthermore, the word is ubiquitous in the marketing of health supplements, energy drinks (eiyou dorinku), and traditional kampo medicine. Advertisements often target the 'tsukare-yasui' demographic, promising to restore vigor and reduce this susceptibility to fatigue. Understanding this word helps learners navigate social expectations regarding productivity and self-care in a Japanese context.

Usage in Advertising

Commonly seen on vitamin B supplements and energy drinks aimed at 'salarymen' and busy parents.

Finally, it is worth noting that tsukare-yasui can also be applied metaphorically or to inanimate objects that lose their 'energy' quickly, though its primary use remains human-centric. For example, a battery that no longer holds a charge well might be described using similar 'yasui' structures, though tsukare-yasui itself is almost exclusively for living beings experiencing physiological or mental drain. In a psychological sense, someone who is mentally fragile or easily overwhelmed by social interactions might also use this term to describe their mental state as seishinteki ni tsukare-yasui (mentally prone to fatigue).

Using 疲れやすい (tsukare-yasui) correctly requires an understanding of i-adjective conjugation and the specific sentence patterns that highlight tendencies. Because it ends in -i, it follows all the standard rules of Japanese adjectives. To say 'I am not easily tired,' you would change it to tsukare-yasukunai. For the past tense, 'I used to get tired easily,' it becomes tsukare-yasukatta. These transformations allow for a high degree of precision when discussing changes in health over time. It is most commonly used in the present tense to describe a current, ongoing state of one's constitution.

Sentence Pattern 1: Subject + wa + Tsukare-yasui

Standard declaration of one's tendency. Example: 'Haha wa saikin tsukare-yasui desu' (My mother gets tired easily lately).

A common way to expand these sentences is by adding a reason or a specific context. You might use the -te form of a verb or a noun followed by de to explain why you are prone to fatigue. For instance, 'Natsubate de tsukare-yasui' (Prone to fatigue due to summer heat exhaustion). This structure is essential for explaining symptoms to a pharmacist or a doctor. It provides the 'why' behind the 'what,' which is crucial for diagnosis and advice. Another common construction involves the use of naru (to become) to indicate a change: 'Saikin, tsukare-yasuku narimashita' (Lately, I have become easily tired).

In more formal or academic writing, you might see tsukare-yasui modifying a noun directly. A 'tsukare-yasui taishitsu' (a constitution that is easily tired) is a common phrase in health magazines and medical blogs. Here, the adjective acts as a descriptor for the person's physical makeup. You can also use it to compare yourself to others or to your younger self. 'Wakai koro ni kurabete, tsukare-yasuku natta' (Compared to when I was young, I've become more easily tired). This comparison is a staple of 'ojisan/obasan' (middle-aged) humor and small talk in Japan, often used to build rapport through shared experiences of aging.

Negative and Past Forms

Negative: 疲れやすくない (Not easily tired). Past: 疲れやすかった (Was easily tired). Negative Past: 疲れやすくなかった (Was not easily tired).

Another nuance to master is the use of degree adverbs. Words like hijou ni (extremely), wari to (relatively), or chotto (a little) can be placed before tsukare-yasui to fine-tune the meaning. 'Saikin wari to tsukare-yasui n desu' (Lately, I'm relatively prone to fatigue) sounds more natural and less dramatic than a flat statement. It conveys a subtle shift in health that might be concerning but not yet an emergency. Mastering these modifiers allows learners to speak with the same level of nuance as a native speaker, especially when discussing sensitive topics like personal well-being.

You will encounter 疲れやすい (tsukare-yasui) in a variety of settings, ranging from the highly clinical to the deeply personal. One of the most common places is on Japanese television during commercial breaks. Japan has a massive market for 'eiyou dorinku' (nutrition drinks) and 'sapuri' (supplements). These commercials often feature a tired office worker or a busy parent looking lethargic, with a narrator asking, 'Saikin, tsukare-yasuku arimasen ka?' (Lately, haven't you been getting tired easily?). This rhetorical question is a classic marketing hook designed to make viewers reflect on their own energy levels and consider buying a product like Chocola BB or Alinamin.

Setting 1: Pharmacy/Drugstore

Look at the packaging of vitamin supplements; 'tsukare-yasui kata ni' (for those who get tired easily) is a standard marketing phrase.

In a clinical setting, such as a hospital or a neighborhood clinic, tsukare-yasui is a key symptom term. When filling out a medical questionnaire (monshinhyou), there is often a checkbox for 'kenroukan' (fatigue) or 'tsukare-yasui'. Doctors use it to gauge the severity of a patient's condition. If a patient says they are 'tsukare-yasui,' the doctor might follow up with questions about their sleep, diet, and stress levels. It is a professional, yet accessible term that facilitates clear communication between healthcare providers and patients. Unlike more technical terms, it is understood by everyone from children to the elderly.

Daily conversation is another rich source of this word. Friends might use it when discussing their weekend plans or why they can't stay out late. 'Gomen, saikin tsukare-yasui kara, kyou wa kaeru ne' (Sorry, I've been getting tired easily lately, so I'm going home today). In this context, it serves as a polite and indisputable excuse. Because fatigue is a universal human experience, citing a 'tsukare-yasui' condition is rarely met with judgment. It is also a common topic among the elderly in Japan, who might discuss their declining 'tairyoku' (stamina) with a mix of resignation and humor during social gatherings or at public baths (sento).

Setting 2: Gym/Fitness Center

Trainers might ask clients if they feel 'tsukare-yasui' to determine if their workout intensity is appropriate or if they need better recovery.

Lastly, you will find it in literature and self-help books. Japan has a prolific 'self-care' publishing industry where titles like 'Why do you get tired easily?' (Naze anata wa tsukare-yasui no ka?) are bestsellers. These books often combine medical advice with lifestyle tips, focusing on everything from breathing techniques to gut health. The word acts as a catch-all for the general malaise that many people feel in modern, high-pressure urban environments like Tokyo or Osaka. By learning this word, you gain a window into the collective consciousness of a society grappling with the balance between intense productivity and physical well-being.

One of the most frequent mistakes English speakers make is confusing 疲れやすい (tsukare-yasui) with the simple past or state-of-being form of the verb tsukareru. In English, we use the word 'tired' for both 'I am tired right now' and 'I get tired easily.' However, in Japanese, these are distinct. Saying 'Watashi wa tsukare-yasui desu' when you actually mean 'I am tired from the walk we just took' is a common error. In the latter case, you should say 'Tsukaremashita' or 'Tsukarete imasu.' Using tsukare-yasui incorrectly makes it sound like you have a chronic health condition or a naturally weak constitution, which might cause unnecessary concern for your Japanese listener.

Mistake 1: Confusing State vs. Tendency

Using 'tsukare-yasui' to mean 'I am tired right now.' Correct: 'Tsukareta' (I'm tired) vs. 'Tsukare-yasui' (I get tired easily).

Another error involves the grammatical construction of the -yasui suffix. Beginners often try to attach -yasui to the dictionary form of the verb (e.g., *tsukareru-yasui) or the negative form. Remember that -yasui must always follow the verb stem (the form you use before -masu). For tsukareru, you drop the -ru to get the stem tsukare. Additionally, because the resulting compound is an i-adjective, it must be conjugated as one. A common mistake is treating it like a na-adjective or a noun, such as saying *'tsukare-yasui da' instead of 'tsukare-yasui desu' or 'tsukare-yasui'.

Learners also sometimes struggle with the 'subject' of the adjective. While you can use tsukare-yasui for yourself, using it to describe someone else requires a degree of sensitivity. Calling someone 'tsukare-yasui' to their face can sound like you are calling them weak or frail (yowai). In Japanese culture, where 'gaman' (endurance) is a virtue, this can be perceived as a slight. If you are concerned about someone, it is better to ask 'Daijoubu desu ka? Tsukarete imasen ka?' (Are you okay? Aren't you tired?) rather than making a definitive statement about their constitution as being 'tsukare-yasui'.

Mistake 2: Overusing it for others

Labeling someone else as 'tsukare-yasui' can sound judgmental. Use 'tsukarete iru you desu ne' (You seem tired) instead.

Lastly, there is the confusion between -yasui and -gachi. Both can mean 'tending to,' but -gachi often implies a negative frequency of an action (like wasure-gachi - tending to forget). While tsukare-gachi exists, it is much less common than tsukare-yasui and has a slightly different nuance of 'being in a state of tiredness often.' For general purposes of describing susceptibility to fatigue, tsukare-yasui is the standard and most natural choice. Avoiding these common pitfalls will make your Japanese sound more natural and prevent misunderstandings regarding your health or the health of others.

While 疲れやすい (tsukare-yasui) is the most common way to express being easily tired, several other words and phrases offer different nuances depending on the context. Understanding these alternatives will help you choose the right word for the right situation, whether you're at a doctor's office or chatting with a friend. One closely related phrase is 体力がない (tairyoku ga nai), which literally means 'to have no physical strength/stamina.' While tsukare-yasui describes the result (getting tired), tairyoku ga nai describes the cause (lack of endurance). You might say 'Tairyoku ga nai kara, tsukare-yasui' (Because I have no stamina, I get tired easily).

体力がない (Tairyoku ga nai)

Focuses on the lack of physical capacity or endurance. Often used when talking about exercise or aging.

虚弱 (Kyojaku)

A more formal, clinical term meaning 'frail' or 'feeble.' Often used for 'kyojaku taishitsu' (a weak constitution).

Another useful alternative is だるい (darui). While not a direct synonym for 'prone to fatigue,' it is often used alongside tsukare-yasui. Darui means 'sluggish,' 'heavy,' or 'languid.' If you feel tsukare-yasui, you likely also feel darui. In a medical context, kenroukan (倦怠感) is the formal term for 'fatigue' or 'malaise.' You will see this on medical forms and in health reports. It is the 'noun' version of the feeling that tsukare-yasui describes as an adjective. If you want to sound very professional or are reading a medical document, this is the word you'll encounter.

For the opposite meaning, the most direct antonym is 疲れにくい (tsukare-nikui). The suffix -nikui means 'difficult to,' so this means 'hard to get tired' or 'having high endurance.' You often see this in advertisements for ergonomic chairs or high-quality walking shoes: 'Tsukare-nikui kutsu' (Shoes that make it hard to get tired). Other opposites include tafu (tough), genki (energetic), and sutamina ga aru (having stamina). Using these antonyms can help you describe positive health goals or the benefits of a product or habit.

疲れにくい (Tsukare-nikui)

The direct opposite. Used for people with high stamina or well-designed products that reduce fatigue.

Finally, consider the word yowai (weak). While broad, it is often used in compound phrases like karada ga yowai (to have a weak body/health). This is a more general way of saying someone is 'tsukare-yasui' and often gets sick easily as well. In casual conversation, people might also use the loanword batterii gire (battery ran out) to describe sudden exhaustion, though this is more about the state of being tired than the tendency to become so. By mastering tsukare-yasui and its relatives, you can navigate the complex Japanese vocabulary for health and vitality with ease.
