慣らす en 30 segundos
- Narasu is a transitive verb meaning to accustom, familiarize, or tame. It requires an object (を) and usually a target environment (に).
- It is commonly used for breaking in new shoes, taming animals, or getting one's body/senses used to new conditions like heat or darkness.
- Distinguish it from the intransitive 'nareru' (to get used to) and the homophone 'narasu' (to ring a bell or level the ground).
- It implies a deliberate, gradual process of reducing resistance or friction between an object and its new environment.
The Japanese verb 慣らす (narasu) is a transitive verb (他動詞) that primarily means to accustom someone or something to a new situation, to familiarize, or to tame an animal. At its core, it represents the active process of bridging the gap between 'unfamiliar/wild' and 'familiar/domesticated.' Unlike its intransitive counterpart 慣れる (nareru), which describes the passive state of getting used to something, 慣らす implies an agent taking action to facilitate that adjustment. This distinction is crucial for B1 learners to master, as it shifts the focus from the person experiencing the change to the person or force causing the change.
- Physical Adjustment
- This refers to breaking in physical objects, such as new shoes or a baseball glove, to make them comfortable. When you buy new leather shoes, they are often stiff and cause blisters. By wearing them for short periods, you 慣らす them to the shape of your feet.
- Biological/Animal Training
- In the context of animals, it means to tame or domesticate. It involves taking a wild or nervous animal and making it comfortable around humans or specific environments. For example, 'taming a wild horse' uses this verb.
- Environmental Acclimatization
- This involves preparing the body or mind for a specific environment, such as 'accustoming one's eyes to the dark' (目を暗闇に慣らす) or 'adjusting one's body to the heat' before a marathon.
新しい靴を履いて歩き、足を慣らす必要があります。(You need to walk in your new shoes to get your feet used to them.)
The word is composed of the kanji 慣, which signifies 'habit,' 'custom,' or 'to become experienced.' The radical on the left is the 'heart' or 'spirit' (りっしんべん), suggesting that the process of 'narasu' involves a change in the internal state or the essence of the object being acted upon. Whether you are taming a hawk or breaking in a pair of boots, you are fundamentally changing the state of that object to make it compatible with a specific purpose or environment. This verb is ubiquitous in Japanese daily life, from sports training to childcare and animal husbandry.
野生の馬を人間に慣らすのは時間がかかる。(It takes time to accustom a wild horse to humans.)
Furthermore, narasu can be used in more abstract or social contexts. For instance, a manager might 'accustom' a new employee to the company culture by giving them small tasks first. In this sense, it is synonymous with 'onboarding' or 'phasing in.' The nuance is always one of gradual, intentional progress. It is not a sudden change, but a series of small steps designed to reduce friction and resistance.
まずは耳を英語の音に慣らすことから始めましょう。(Let's start by getting your ears used to the sounds of English.)
- Sensory Adaptation
- Using the verb with senses like eyes (目) or ears (耳) is very common. It describes the physiological process of adaptation.
Using 慣らす (narasu) correctly requires an understanding of Japanese transitivity and verb conjugation. As a Godan verb (Group 1), it follows standard patterns but is often confused with its homophone 鳴らす (narasu - to ring/sound) and its intransitive pair 慣れる (nareru). To use it effectively, follow the structure: [Agent] は [Object] を [Environment/State] に 慣らす.
1. Conjugation Patterns
Since it is a Godan verb ending in ~su, the stem changes as follows:
- Dictionary Form: 慣らす (narasu)
- Negative Form: 慣らさない (narasanai)
- Polite Form: 慣らします (narashimasu)
- Te-form: 慣らして (narashite)
- Past Form: 慣らした (narashita)
- Potential Form: 慣らせる (naraseru)
- Causative Form: 慣らさせる (narasaseru)
- Passive Form: 慣らされる (narasareru)
2. Common Sentence Structures
The most frequent usage involves preparing a person or animal for a new environment. For example, when moving a pet to a new house: '猫を新しい家に慣らす' (Accustom the cat to the new house). Note the use of the particle に to indicate the target environment and を for the object being accustomed.
少しずつ体を寒さに慣らしていく。(I will gradually get my body used to the cold.)
3. Distinction from 慣れる (Nareru)
This is the most common point of confusion for B1 students. 慣れる is intransitive: 'I got used to the cold' (寒さに慣れた). 慣らす is transitive: 'I accustomed my body to the cold' (体を寒さに慣らした). Use narasu when you want to emphasize the effort or the process of training/adjusting something.
- Intentionality
- Narasu implies a deliberate action. If you are 'breaking in' shoes, you are doing it on purpose. If you 'get used' to shoes just by wearing them naturally, nareru is more common.
4. Compound Verbs
Narasu is often combined with other verbs. The most common is 使い慣らす (tsukai-narasu), meaning to become accustomed to using a tool through frequent use, or 飼い慣らす (kai-narasu), meaning to domesticate or bring an animal under control.
You will encounter 慣らす (narasu) in a variety of settings, ranging from the domestic to the professional. Understanding these contexts helps in grasping the subtle nuances of the word beyond its dictionary definition.
1. Domestic and Daily Life
In a household setting, you might hear this regarding children or pets. Parents talk about 慣らす when introducing a baby to solid foods (離乳食に慣らす) or when a child starts daycare (保育園に慣らす). It suggests a gentle, phased introduction to something new and potentially overwhelming.
まずは短時間から保育園に慣らしていきましょう。(Let's start by getting [the child] used to the nursery school for short periods.)
2. Sports and Physical Training
Athletes use this term frequently. Before a big race in a different climate, they might arrive early to 体を現地の気候に慣らす (accustom their bodies to the local climate). It is also used for 'warming up' or 'breaking in' equipment like gloves, bats, or running shoes.
3. Animal Training and Nature Documentaries
If you watch Japanese nature programs or pet training shows, 慣らす is a keyword. It describes the process of a wild animal becoming less fearful of humans. A common phrase is 人間に慣らす (to make [an animal] used to humans).
- 飼い慣らす (Kainarasu)
- This specific version is used for taming. It can also be used metaphorically in literature to describe 'taming' a person's wild spirit or a difficult subordinate.
4. Business and Technology
In the tech world, narasu can refer to 'burn-in' periods for electronic components or 'running in' an engine (engine o narasu). In business, it refers to the adjustment period for new staff or the gradual introduction of a new system to a workforce.
Even advanced learners of Japanese can stumble when using 慣らす (narasu). The mistakes usually fall into three categories: transitivity errors, homophone confusion, and nuance mismatches.
1. The Transitivity Trap (慣れる vs. 慣らす)
The most frequent error is using narasu when you mean nareru. Remember: Nareru is something that happens to you; Narasu is something you do to something else.
❌ Wrong: 日本の生活に慣らしました (I accustomed to Japanese life).
✅ Right: 日本の生活に慣れました (I got used to Japanese life).
✅ Right: 体を日本の生活に慣らしました (I accustomed my body to Japanese life).
2. Homophone Confusion (鳴らす vs. 慣らす vs. 均す)
Japanese has several verbs pronounced narasu, and they are written with different kanji. Confusing them in writing is a common mistake for both learners and native speakers.
- 鳴らす (Narasu)
- To make a sound (e.g., ring a bell, honk a horn). Kane o narasu (Ring a bell).
- 均す (Narasu)
- To level or smooth out (e.g., leveling the ground, averaging numbers). Tochi o narasu (Level the land).
3. Overusing 'Narasu' for People
While you can 'accustom' a person to a situation, using narasu for people can sometimes sound a bit like you are treating them like an animal or an object, especially if you use kainarasu (tame). In professional settings, 馴染ませる (najimaseru - to let them blend in/get comfortable) or 適応させる (tekiou saseru - to make them adapt) is often more polite and appropriate.
To truly master 慣らす (narasu), it is helpful to compare it with related verbs that share similar meanings but have distinct nuances. Japanese is rich in verbs that describe 'adjustment' and 'adaptation.'
1. 馴染ませる (Najimaseru)
This verb means 'to let something blend in' or 'to make something familiar.' While narasu focuses on the process of overcoming resistance or stiffness, najimaseru focuses on harmony and integration. You najimaseru flavors in cooking or najimaseru a new person into a group.
2. 順応させる (Junnou saseru)
This is a more formal, academic, or biological term meaning 'to make adapt.' It is often used in scientific contexts, such as plants adapting to a new environment or humans adapting to high altitudes. It lacks the 'breaking in' nuance of narasu.
3. 調教する (Choukyou suru)
This specifically means 'to train' animals, especially for performance or work (like horses or circus animals). While narasu is about getting an animal used to humans, choukyou is about teaching them specific skills or commands.
- 飼い慣らす (Kainarasu)
- A compound of 'keep/raise' and 'accustom.' It means to tame a wild animal so it can be kept as a pet or livestock. Metaphorically, it means to bring someone under one's thumb.
ドレッシングを野菜に馴染ませる。(Let the dressing soak into/blend with the vegetables.)
Choosing the right word depends on the object and the desired outcome. Use narasu for physical objects, basic animal comfort, and sensory adaptation. Use najimaseru for social integration and culinary blending. Use junnou saseru for formal or biological adaptation.
