慣れる

To get used to.

nareru Top 1,500

At the A1 level, learners are just beginning their journey into the Japanese language. The verb '慣れる' (nareru) might seem a bit advanced for absolute beginners, but it is introduced early because of its high frequency in daily greetings and basic inquiries about well-being. A1 learners will primarily encounter '慣れる' in its past formal form, '慣れました' (narema-shita), as part of a set phrase. When a beginner moves to Japan, starts a new language school, or joins a new host family, they will frequently be asked, '日本に慣れましたか？' (Have you gotten used to Japan?). At this stage, the goal is not to master complex grammar structures, but simply to recognize this question and know how to respond politely. A simple 'はい、慣れました' (Yes, I have gotten used to it) or 'いいえ、まだです' (No, not yet) is perfectly sufficient. The focus is on auditory recognition and basic social interaction. Learners at this level should associate the sound 'nareru' with the concept of 'getting comfortable' or 'adjusting.' They do not need to worry about nominalizing verbs or using the te-iru form yet. The primary objective is to survive basic social encounters where locals are checking in on their comfort level. Understanding that 'に' (ni) is the particle used before '慣れましたか' is a bonus, but rote memorization of the phrase '〜に慣れましたか' is the most practical approach for A1 survival Japanese. It builds a foundation for empathy and connection with native speakers who are showing concern for the learner's adaptation process.

At the A2 level, learners are expanding their ability to describe their daily routines, personal experiences, and immediate environment. '慣れる' becomes a highly active and essential part of their vocabulary. They move beyond just answering 'Yes' or 'No' to set phrases and start generating their own sentences to describe what they are getting used to. A2 learners must master the rule that '慣れる' takes the particle 'に' (ni). They will practice sentences like '新しい仕事に慣れました' (I got used to my new job) or '日本の食べ物に慣れました' (I got used to Japanese food). Furthermore, A2 is the critical stage where learners are introduced to the te-form and its variations. They will learn to use '慣れています' (narete imasu) to describe their current state of being accustomed to something, distinguishing it from the simple past tense. They will also begin to use the negative form '慣れていません' (narete imasen) to express things they still find difficult. Another significant milestone at the A2 level is learning to nominalize verbs using 'こと' (koto) or 'の' (no). This unlocks the ability to say things like '早く起きることに慣れました' (I got used to waking up early). This structural leap allows A2 learners to express much more complex ideas about their personal growth and daily struggles, making their Japanese significantly more expressive and functional for everyday life and basic workplace communication.

At the B1 level, learners are becoming independent users of Japanese. They can handle most situations likely to arise while travelling in an area where the language is spoken and can produce simple connected text on topics that are familiar or of personal interest. For '慣れる', this means using it with greater nuance and in a wider variety of grammatical structures. B1 learners will frequently use the subsidiary verb '〜てくる' (te kuru) with '慣れる' to express the gradual, ongoing process of adaptation: 'だんだん日本の生活に慣れてきました' (I have gradually come to get used to life in Japan). This adds a layer of temporal depth to their speech that sounds much more natural than simple past tense. They will also start using '慣れる' as a suffix attached to verb stems to create compound verbs, such as '使い慣れる' (to get used to using), '住み慣れる' (to get used to living in), and '見慣れる' (to get used to seeing). This demonstrates a significant expansion of their vocabulary and grammatical flexibility. B1 learners will also encounter '慣れる' in more complex conditional sentences, like '慣れれば、簡単になります' (If you get used to it, it becomes easy). They are expected to discuss their adaptation processes in detail, explaining *why* they are struggling or *how* they overcame difficulties, moving beyond simple statements of fact into narrative and explanation.

At the B2 level, learners possess a degree of fluency and spontaneity that makes regular interaction with native speakers quite possible without strain for either party. Their use of '慣れる' becomes highly sophisticated and nuanced. They are comfortable using it in abstract contexts, discussing not just physical or environmental adaptation, but psychological, cultural, and systemic habituation. A B2 learner might discuss getting used to a different corporate culture, a new political system, or a complex software architecture. They will seamlessly integrate adverbs to modify the degree of adaptation, using phrases like 'すっかり慣れた' (completely gotten used to) or 'いまだに慣れない' (still haven't gotten used to it even now). Furthermore, B2 learners will adeptly use the negative adjectival forms '見慣れない' (unfamiliar looking) and '聞き慣れない' (unfamiliar sounding) to describe novel stimuli in their environment. They understand the subtle differences between '慣れる' and its synonyms like '馴染む' (najimu) or '順応する' (jun'nou suru), choosing the exact right word for the context. In professional settings, they can use formal apologies involving '慣れる', such as '不慣れな点が多く、申し訳ありません' (I apologize for the many areas where I am inexperienced/unaccustomed). At this stage, '慣れる' is a tool for expressing deep cultural integration and complex personal and professional development.

At the C1 level, learners can express themselves fluently and spontaneously without much obvious searching for expressions. They use language flexibly and effectively for social, academic, and professional purposes. The use of '慣れる' at this level is characterized by idiomatic usage, high-level compound verbs, and a deep understanding of sociolinguistic register. C1 learners will use phrases like '場馴れしている' (ba-nare shite iru - to be used to a particular situation/to have stage presence) or '人馴れしている' (hito-nare shite iru - to be used to people/tame). They can effortlessly navigate complex sentences where '慣れる' is embedded in multiple clauses, discussing the psychological theories of habituation or the sociological impacts of cultural assimilation. They are acutely aware of the register and will opt for more formal synonyms like '順応' or '適応' in academic writing, while reserving '慣れる' for conversational or literary contexts where a subjective, emotional tone is desired. C1 learners also understand the cultural weight of '慣れる' in Japanese society—the expectation of endurance and the virtue of silent adaptation. They can read between the lines when a native speaker says 'まあ、そのうち慣れるよ' (Well, you'll get used to it eventually), recognizing whether it's meant as genuine encouragement or a dismissive platitude. Their mastery of '慣れる' reflects a near-native intuition for the language's rhythm and cultural underpinnings.

At the C2 level, learners have reached near-native proficiency. They can understand with ease virtually everything heard or read and can summarize information from different spoken and written sources, reconstructing arguments and accounts in a coherent presentation. For a C2 learner, '慣れる' is a fully integrated component of their vast linguistic repertoire. They can deploy it in highly literary, poetic, or philosophical contexts. They might analyze a classic Japanese novel and discuss how the protagonist's '慣れ' (nare - the noun form, meaning habituation or familiarity) leads to complacency or tragedy. They can invent their own compound verbs using '慣れる' if the situation demands a creative linguistic solution, and native speakers will accept it as natural. C2 learners understand the absolute deepest nuances of the word, including its potential negative connotations—how '慣れ' can sometimes imply a loss of freshness, a taking-for-granted, or a dulling of the senses (e.g., 'マンネリ化' or getting stuck in a rut due to over-familiarity). They can debate the philosophical difference between active adaptation and passive resignation, using '慣れる' as a central conceptual pivot. At this ultimate level of mastery, the learner's use of '慣れる' is indistinguishable from that of a highly educated native speaker, reflecting a profound, instinctual grasp of human psychology as expressed through the Japanese language.

Practice it Examples Notes & Tips

慣れる in 30 Seconds

Means 'to get used to' or 'to grow accustomed to'.
Always takes the target particle 'に' (ni), never 'を' (wo).
Use '慣れている' (te-iru form) for your current state of being used to something.
Can attach to verb stems (e.g., 使い慣れる) to mean 'used to doing'.

The Japanese verb '慣れる' (nareru) is a fundamental vocabulary item that translates to 'to get used to,' 'to grow accustomed to,' or 'to become familiar with.' It is an ichidan verb, meaning its conjugation follows the simpler pattern of dropping the final 'ru' and adding the appropriate suffix. Understanding this word is absolutely crucial for learners of Japanese, as it frequently appears in everyday conversations, particularly when discussing transitions, new experiences, or adapting to different environments. When you move to a new country, start a new job, or begin learning a new skill, '慣れる' is the verb you will use to describe the psychological and physiological process of adaptation. The concept of habituation is deeply embedded in human psychology, and in Japanese culture, acknowledging the effort it takes to adapt is a common social grace. For instance, when someone starts a new job, colleagues will often ask, '仕事に慣れましたか？' (Have you gotten used to the work?). This is not merely a question about task proficiency, but a genuine inquiry into the person's overall well-being and comfort level in their new environment.

Core Meaning: The primary definition revolves around the psychological and physical adaptation to a new stimulus, environment, or routine until it no longer feels foreign or difficult.

新しい環境に慣れるのは時間がかかります。

The verb implies a passage of time. You cannot '慣れる' instantly; it is a gradual process. This temporal aspect is why it is often used with expressions of time or in the continuous/state form (慣れている - to be in a state of being used to something). Furthermore, '慣れる' can be attached to the stem of other verbs to indicate that one has become accustomed to performing that specific action. For example, '使い慣れる' (tsukainareru) means to get used to using something, like a new tool or software. '住み慣れる' (suminareru) means to get used to living in a place. This compound verb structure significantly expands your expressive capabilities in Japanese.

Compound Usage: Attaching 慣れる to a verb stem (V-masu stem + 慣れる) creates a new verb meaning 'to be used to doing V'.

このパソコンは使い慣れているので、仕事が早いです。

The kanji for '慣' (kan) is composed of the heart radical (忄) and a phonetic component. The heart radical hints at the internal, psychological nature of becoming accustomed to something. It is not just a physical repetition, but an emotional and mental settling.

日本の生活に慣れるまで、大変でした。

When learning this word, it is beneficial to practice it in various tenses. '慣れました' (I got used to it), '慣れません' (I cannot get used to it), and '慣れてきました' (I am gradually getting used to it) are all highly frequent variations. The use of '〜てくる' (te kuru) with '慣れる' is particularly natural, as it emphasizes the ongoing, developing nature of the adaptation process from the past up to the present moment.

Nuance of State: Using the te-iru form (慣れている) describes the current state of already being accustomed to something, rather than the action of getting used to it.

彼は早起きに慣れている。

辛い食べ物に慣れることはないだろう。

Ultimately, mastering '慣れる' allows you to articulate your personal journey of growth and adaptation, making your Japanese sound much more expressive and deeply connected to human experience.

Using '慣れる' correctly involves understanding its grammatical requirements and the typical contexts in which it appears. The most critical grammatical rule to remember is that the object of adaptation is marked by the target particle 'に' (ni). You are moving *toward* a state of familiarity with something, hence the directional/target particle. Saying '仕事を慣れる' is grammatically incorrect and sounds very unnatural to native speakers; it must always be '仕事に慣れる'. This applies to nouns, noun phrases, and nominalized verbs.

Basic Structure: [Noun] + に + 慣れる (To get used to [Noun])

日本の気候に慣れる。

When you want to express getting used to *doing* an action, you must nominalize the verb using 'こと' (koto) or 'の' (no) before adding 'に慣れる'. For example, 'getting used to waking up early' would be '早く起きることに慣れる' (hayaku okiru koto ni nareru). This structure is incredibly versatile and allows you to describe complex adaptation processes. Another vital aspect of using '慣れる' is understanding the difference between its dynamic and stative forms. '慣れる' (dictionary form) or '慣れます' (masu form) indicates the future action or general fact of getting used to something. '慣れた' (ta form) or '慣れました' indicates that the process of getting used to something has been completed in the past. However, to describe your *current state* of being accustomed to something, you must use the te-iru form: '慣れている' (narete iru).

Stative Form: [Noun] + に + 慣れている (To be currently used to [Noun])

私は一人暮らしに慣れています。

If you want to express the gradual process of becoming accustomed to something, you should pair '慣れる' with the subsidiary verb '〜てくる' (te kuru). '慣れてくる' literally means 'to come to be used to'. This is exceptionally common in daily conversation because adaptation is rarely instantaneous.

最近、やっとこの仕事に慣れてきました。

Furthermore, as mentioned in the meaning section, '慣れる' acts as a powerful suffix. By taking the masu-stem of a verb and attaching '慣れる', you create a new compound verb.

Verb Suffix: [Verb Masu-Stem] + 慣れる (To be used to doing [Verb])

この靴は履き慣れているから、疲れません。

見慣れない人が教室にいます。

The negative form '見慣れない' (minarenai - unfamiliar looking) or '聞き慣れない' (kikinarenai - unfamiliar sounding) are frequently used as adjectives to describe things that are new or strange to the speaker's senses. Mastering these various structures will elevate your Japanese from basic textbook sentences to natural, fluent communication.

The verb '慣れる' is ubiquitous in Japanese society, reflecting a culture that places a high value on harmony, adaptation, and perseverance through transitional phases. You will hear it in almost every facet of life, from casual chats with friends to formal business meetings. One of the most common environments where '慣れる' is heavily utilized is the workplace. April is the traditional start of the business and academic year in Japan. During this time, millions of new employees (新入社員) and students enter new environments. Consequently, throughout April and May, the phrase '仕事に慣れましたか？' (Have you gotten used to the work?) or '学校に慣れましたか？' (Have you gotten used to school?) echoes across the country. It functions almost as a seasonal greeting.

Workplace Context: Supervisors and colleagues use it to check on the mental and operational adjustment of new team members.

新しい部署にはもう慣れましたか。

Another prominent context is language learning and cultural adaptation. When foreigners live in Japan, locals frequently ask them about their adjustment process. Questions like '日本の生活に慣れましたか？' (Have you gotten used to life in Japan?) or '日本食に慣れましたか？' (Have you gotten used to Japanese food?) are standard conversation starters. You will also encounter '慣れる' extensively in media, such as anime, manga, and dramas. Characters thrust into magical worlds, new schools, or difficult training regimens will constantly discuss their struggles to '慣れる' to their new reality. It is a core vocabulary word for character development arcs.

Media & Pop Culture: Used to highlight a character's growth, resilience, or current struggle with a new, often overwhelming, situation.

こんな厳しい訓練、絶対に慣れないよ！

In the context of technology and consumer goods, '慣れる' is used in reviews and tutorials. Reviewers might say that a new smartphone's interface is confusing at first, but '使っているうちに慣れる' (you get used to it as you use it).

操作に慣れるまで少し時間がかかります。

Medical & Physical: Doctors or physical therapists might use it when discussing adjusting to new medication, prosthetics, or physical routines.

コンタクトレンズに慣れるのは大変でした。

都会の騒音にはいつまでたっても慣れない。

Understanding the diverse contexts in which '慣れる' appears will not only improve your listening comprehension but also provide you with deep insights into the Japanese mindset regarding change, endurance, and social empathy.

While '慣れる' is a relatively straightforward verb in terms of conjugation, learners frequently stumble over its particle usage, tense selection, and distinction from similar-sounding or similar-meaning words. The single most pervasive error is the incorrect use of the object particle 'を' (wo) instead of the target particle 'に' (ni). Because English speakers say 'I get used TO something,' they might intuitively grasp the need for a directional particle, but those translating directly from languages where the object of adaptation is a direct object often default to 'を'.

Particle Error: Using を instead of に. 慣れる is an intransitive verb; it does not take a direct object.

❌ 仕事を慣れる。
⭕ 仕事に慣れる。

Another major area of confusion lies in the tense and aspect. Learners often use the simple past tense '慣れた' (got used to) when they actually mean to describe their current, ongoing state of being accustomed to something, which requires the te-iru form '慣れている'.

Tense Confusion: Failing to distinguish between the completion of the adaptation process (past tense) and the current state of being adapted (te-iru form).

❌ 私は毎朝ジョギングすることに慣れます。(I will get used to...)
⭕ 私は毎朝ジョギングすることに慣れています。(I am used to...)

A third common mistake occurs when learners try to use '慣れる' with verbs without nominalizing them first. You cannot attach 'に慣れる' directly to a dictionary form verb. You must insert 'こと' or 'の'.

❌ 漢字を書くに慣れる。
⭕ 漢字を書くことに慣れる。

Nominalization Failure: Forgetting to turn a verb phrase into a noun phrase before applying the particle に.

Additionally, learners sometimes confuse '慣れる' (to get used to) with '習う' (narau - to learn) due to their visual similarity in romaji and slight phonetic resemblance. However, their kanji and meanings are entirely different.

❌ 日本語を慣れる。(Intending to say 'learn Japanese')
⭕ 日本語を習う。

❌ 運転に慣れましたか？ (When asking if someone learned to drive)
⭕ 運転を習いましたか？

By paying close attention to the 'に' particle, utilizing the 'てくる' and 'ている' forms correctly, and always nominalizing verbs before 'に慣れる', you can avoid these common pitfalls and speak with much greater accuracy and natural flow.

In Japanese, there are several words that share conceptual similarities with '慣れる', dealing with adaptation, familiarity, and habituation. Understanding the nuances between these synonyms will greatly enrich your vocabulary and allow for more precise expression. The most closely related concept is '習慣' (shuukan), which means 'habit' or 'custom'. While '慣れる' is the verb describing the process of getting used to something, '習慣' is the noun representing the established routine that results from that process.

習慣 (Shuukan) vs. 慣れる: 習慣 is a noun meaning habit. 慣れる is the verb for getting used to something. You get used to (慣れる) waking up early, and then it becomes a habit (習慣).

早起きに慣れて、それが習慣になった。

Another related word is '馴染む' (najimu), which translates to 'to become familiar with,' 'to blend in,' or 'to fit in.' While '慣れる' focuses on the internal, psychological adaptation to a stimulus, '馴染む' often implies a more harmonious integration into a group, environment, or physical fit (like a pair of shoes molding to your feet).

馴染む (Najimu) vs. 慣れる: 馴染む carries a stronger nuance of blending in seamlessly and harmoniously, often used for interpersonal relationships or physical fit.

新しいクラスに馴染む。(To blend into the new class)

'順応する' (jun'nou suru) is a more formal, academic, or scientific term for 'to adapt' or 'to acclimatize.' You would use this in written reports, scientific contexts (like evolutionary biology), or highly formal speech, whereas '慣れる' is the everyday conversational equivalent.

動物は環境の変化に順応する。(Animals adapt to environmental changes)

順応する (Jun'nou suru) vs. 慣れる: 順応する is a formal, objective term for adaptation, often used in scientific or sociological contexts. 慣れる is subjective and conversational.

Finally, there is '適応する' (tekiou suru), which means 'to adapt' or 'to conform.' Similar to '順応する', it is formal and often implies a necessary adjustment to meet specific requirements or survive in a new system.

社会の変化に適応する。(To adapt to changes in society)

新しいシステムに慣れる。(To get used to the new system)

By differentiating between the everyday psychological comfort of '慣れる', the harmonious blending of '馴染む', and the formal adaptation of '順応する' and '適応する', you can navigate Japanese vocabulary with precision and cultural awareness.

Sentence Patterns

How to Use It

note

While '慣れる' is generally positive or neutral (adapting to survive/function), in advanced contexts, '慣れ' (the noun) can have a negative connotation, implying complacency, loss of tension, or taking things for granted (e.g., 慣れによるミス - mistakes caused by complacency).

Common Mistakes

Using the particle を instead of に (e.g., 仕事を慣れる instead of 仕事に慣れる).
Using the past tense 慣れた when describing a current, ongoing state of familiarity (should be 慣れている).
Forgetting to nominalize verbs with こと or の before に慣れる (e.g., 起きるに慣れる instead of 起きることに慣れる).
Confusing 慣れる (to get used to) with 習う (to learn) due to phonetic similarity.
Using 慣れる when 馴染む (to blend in/fit in) would be more appropriate for social situations.

Tips

The Golden Rule of に

If you only remember one thing about 慣れる, remember that it takes the particle に. Tattoo '〜に慣れる' in your brain. Using を is the fastest way to sound unnatural.

The Power of てくる

Native speakers rarely adapt to things instantly. Use '慣れてきました' (I'm getting used to it) instead of just '慣れました' to sound incredibly natural and humble about your progress.

Build Compound Verbs

Supercharge your vocabulary by attaching 慣れる to verb stems. 住み慣れる (used to living), 履き慣れる (used to wearing shoes), 見慣れる (used to seeing). It makes you sound very fluent.

Listen for Adjectives

Watch out for 見慣れない (minarenai) and 聞き慣れない (kikinarenai). They are verbs acting as adjectives to describe things that look or sound unfamiliar. They pop up constantly in anime and news.

The Empathy Question

When Japanese people ask '慣れましたか', they are showing they care about your well-being. Always acknowledge their kindness, perhaps by starting your reply with 'おかげさまで' (Thanks to you/Thankfully).

Nominalization is Key

In essays, don't just say you got used to a noun. Say you got used to *doing* an action. Use '〜することに慣れる'. It demonstrates a higher level of grammatical control.

State vs. Action

Don't mix up 慣れた (the event of getting used to it happened) and 慣れている (the current state of being used to it). If you are describing a skill you possess now, use 慣れている.

Narau vs. Nareru

Do not confuse 慣れる (to get used to) with 習う (to learn). You 'narau' Japanese grammar, but you 'nareru' to speaking it. They are completely different concepts.

The Danger of Nare

At advanced levels, be aware that '慣れ' (the noun) can be negative. '慣れが生じる' means complacency has set in. It's a great concept to use in business or philosophical discussions.

Flat Pitch

慣れる has a 'heiban' (flat) pitch accent. The pitch goes up on 're' and stays high on 'ru'. Don't drop the pitch at the end, or it might sound like a different word or unnatural.

Memorize It

Mnemonic

Imagine you are trying to catch a slippery EEL. At first, it's hard, but eventually, you get used to it. NA-RE-RU sounds like 'Not a Real Eel'. Getting used to holding 'Not a Real Eel' takes time.

Word Origin

The kanji 慣 (kan/nareru) is composed of the heart radical 忄 (kokoro) and the phonetic component 貫 (kan - to pierce/penetrate). Together, they suggest a feeling or state of mind that has deeply penetrated or become fixed, hence 'accustomed'.

Cultural Context

In Japanese companies, the first few months are often treated as an observation period where 'getting used to the atmosphere' (雰囲気に慣れる) is considered more important than immediate results.

Showing that you have 'gotten used to' local customs (like taking off shoes or sorting trash meticulously) is the fastest way to gain the respect and trust of Japanese neighbors.

Frequently Asked Questions

10 questions

No, you should never use 'を' (wo) with 慣れる. It is an intransitive verb. You are moving *toward* a state of familiarity, so you must use the target/directional particle 'に' (ni). For example, '仕事に慣れる' is correct, while '仕事を慣れる' is incorrect.

'慣れた' (nareta) is the simple past tense, meaning the action of getting used to something was completed in the past. '慣れている' (narete iru) describes your current state. If you want to say 'I am used to spicy food' as a general fact about yourself right now, you must use '慣れている'.

To express an ongoing process of adaptation, use the te-form plus the subsidiary verb くる (kuru). '慣れてきました' (narete kimashita) means 'I have gradually come to get used to it' or 'I am getting used to it'. Adding 'だんだん' (dandan - gradually) makes it sound even more natural.

Yes, but you cannot attach it directly to a dictionary form verb. You must nominalize the verb first by adding 'こと' (koto) or 'の' (no). For example, '早く起きることに慣れる' (hayaku okiru koto ni nareru) means 'to get used to waking up early'.

'使い慣れる' (tsukai-nareru) is a compound verb. By taking the masu-stem of a verb (like 使う -> 使い) and adding 慣れる, it means 'to get used to doing [verb]'. So, 使い慣れる means to get used to using something, like a specific tool or software.

The dictionary form '慣れる' is neutral. It can be made polite by conjugating it to '慣れます' (naremasu) or '慣れました' (naremashita). It is perfectly acceptable to use in both casual conversations with friends and formal business settings, provided the conjugation matches the required politeness level.

If you have adjusted well, you can say 'はい、おかげさまで慣れました' (Yes, thankfully I have gotten used to it). If you are still adjusting, you can say 'だんだん慣れてきました' (I am gradually getting used to it). If you are struggling, a polite 'まだ少し慣れません' (I am still a little unused to it) is fine.

There isn't a single perfect antonym verb. To express not being used to something, you simply use the negative form: '慣れない' (narenai) or '慣れていない' (narete inai). You can also use the na-adjective '不慣れな' (funarena) for inexperience, or verbs like '戸惑う' (tomadou - to be bewildered) for the feeling of unfamiliarity.

Yes, the kanji is 慣. It is composed of the heart radical (忄) on the left, which relates to feelings and the mind, and the phonetic component 貫 on the right. It is read as 'na' in 'nareru' and 'kan' in words like '習慣' (shuukan - habit).

Yes, you can get used to bad things. For example, '痛みに慣れる' (to get used to pain) or '騒音に慣れる' (to get used to noise). In advanced contexts, the noun form '慣れ' can imply complacency, like '慣れによるミス' (a mistake caused by being too accustomed/complacent).
