練習する

The Japanese word 練習する (renshuu suru) is a fundamental vocabulary item that translates directly to the English verb 'to practice'. It is categorized as a Group 3 verb, also known as a suru-verb, which means it is formed by combining the noun 練習 (renshuu, meaning 'practice' or 'training') with the versatile verb する (suru, meaning 'to do'). To truly understand what this word means and when people use it, we must first break down the kanji characters that make up the noun portion. The first character, 練 (ren), carries the meaning of 'to knead', 'to train', or 'to polish'. It evokes the image of working with a material repeatedly until it reaches the desired consistency or quality, much like a blacksmith folding steel or a baker kneading dough. The second character, 習 (shuu), means 'to learn' or 'to study', and is famously part of the word 習う (narau, to learn). When combined, these two characters beautifully encapsulate the essence of practice: the act of learning something through repetitive, deliberate training and polishing of one's skills. This word is an essential part of daily Japanese communication, especially for students, athletes, musicians, and language learners.

Core Meaning

The core meaning of 練習する revolves around the repetitive execution of an action or skill with the specific goal of improvement, mastery, or preparation for a performance or test.

When considering when people use this word, it is crucial to distinguish it from other forms of learning. In English, we might say we are 'studying' a language or 'practicing' a language almost interchangeably in casual conversation. However, in Japanese, 練習する is strictly reserved for active, skill-based repetition. You do not use 練習する when you are reading a textbook to understand a new historical fact; that would be 勉強する (benkyou suru, to study). Instead, you use 練習する when you are speaking Japanese sentences out loud repeatedly to improve your pronunciation, or when you are writing kanji characters over and over again to memorize their stroke order. It implies a physical or active cognitive engagement where muscle memory or rapid recall is being developed.

Sports Context

In the context of sports, 練習する is the standard word used for team practices, individual drills, and physical conditioning aimed at improving athletic performance.

Furthermore, the concept of practice in Japanese culture carries a significant weight. The dedication to repetitive training is highly valued, often seen as a reflection of one's character and perseverance. This cultural nuance means that when someone says they are going to 練習する, it is generally met with respect and encouragement. It is not just about the mechanical act of doing something repeatedly; it is about the pursuit of excellence and the commitment to self-improvement. Whether it is a child practicing writing their hiragana, a high school student attending their daily club activities (部活 - bukatsu) to practice baseball, or an adult practicing a presentation for work, the word encompasses a wide range of dedicated efforts.

Music Context

For musicians, this word is used daily. Whether it is scales, a new piece of sheet music, or vocal warm-ups, the act of honing musical ability is always described with this verb.

It is also worth noting that 練習する can be used both transitively and intransitively, though it is most commonly used as a transitive verb taking the object particle を (wo). You practice 'something'. However, in contexts where the activity is already understood, or when referring to the general act of practicing, the object can be omitted. For example, a coach might simply yell '練習しろ！' (Renshuu shiro! - Practice!) without specifying what to practice, because the context of the sport makes it obvious. In professional or highly formal settings, while 練習する is perfectly acceptable, you might also encounter more specialized terms, but for everyday conversation, this is the absolute go-to word. Understanding the boundaries of this word—knowing that it applies to skills, sports, music, and active language production, but not to passive academic study—is key to sounding natural in Japanese.

Mastering the usage of 練習する (renshuu suru) in sentences requires a solid understanding of Japanese verb conjugation, specifically the rules governing Group 3 verbs (irregular verbs). Because 練習する is composed of a noun (練習) and the verb する (to do), all the conjugation happens on the する part. This makes it incredibly predictable once you know how to conjugate する. In its dictionary form, it is 練習する, which is used in casual speech for present or future tense. When speaking politely to someone you are not close friends with, or to a superior, you must change it to the formal (masu) form: 練習します (renshuu shimasu). This polite form is what most beginners learn first, and it is the safest form to use in everyday interactions in Japan. The negative casual form is 練習しない (renshuu shinai - do not practice), and the negative polite form is 練習しません (renshuu shimasen).

Basic Conjugation

The verb conjugates entirely based on the 'suru' component. Present polite is 'shimasu', past polite is 'shimashita', te-form is 'shite'.

One of the most important grammatical points to remember when constructing sentences with 練習する is the use of particles. The object of your practice—the thing you are actively working on—is marked by the object particle を (wo). For instance, if you are practicing tennis, tennis is the direct object, so you say テニスを練習する (tenisu o renshuu suru). If you are practicing a song, it becomes 歌を練習する (uta o renshuu suru). Sometimes, learners mistakenly try to use the particle に (ni) or で (de) to mark the object, which sounds unnatural. The particle で (de) is used, however, to indicate the location where the practice takes place. For example, 公園でサッカーを練習する (kouen de sakkaa o renshuu suru) means 'to practice soccer at the park'. The particle に (ni) can be used to indicate the purpose of going somewhere, combined with the stem form, though with suru-verbs it is often just the noun: 練習に行く (renshuu ni iku - to go to practice).

Using Particles

Always use the particle を (wo) to mark the skill, sport, or subject being practiced. Use で (de) for the location of the practice.

Another very common and highly useful sentence pattern involves the te-form of the verb: 練習して (renshuu shite). The te-form is incredibly versatile. When combined with the auxiliary verb いる (iru), it forms the present continuous tense, indicating an action that is currently ongoing. 練習している (renshuu shite iru) or its polite equivalent 練習しています (renshuu shite imasu) translates to 'I am practicing (right now)' or 'I have been practicing (as a habit)'. For example, if someone calls you and asks what you are doing, you might reply, 今、ピアノを練習しています (Ima, piano o renshuu shite imasu - I am practicing the piano right now). The te-form is also used to make requests. By adding ください (kudasai) to the te-form, you get 練習してください (renshuu shite kudasai), which means 'Please practice'. Teachers and coaches use this phrase constantly.

Continuous Form

Use 練習している (renshuu shite iru) to express that you are currently in the middle of practicing, or that practicing is a current ongoing habit.

You can also express desire or intention with this verb. To say 'I want to practice', you remove the 'masu' from the polite form and add 'tai', resulting in 練習したい (renshuu shitai). If you want to express that you must practice, you use the 'nakereba narimasen' or 'nakya' grammar points: 練習しなければなりません (renshuu shinakereba narimasen - I must practice) or the casual 練習しなきゃ (renshuu shinakya). Furthermore, you can use the potential form to express the ability to practice: 練習できる (renshuu dekiru - can practice). For example, 今日は忙しくて練習できない (Kyou wa isogashikute renshuu dekinai - I am busy today and cannot practice). By mastering these various conjugations and sentence structures, you will be able to express a wide array of thoughts and situations regarding your training and skill development in Japanese.

The word 練習する (renshuu suru) is ubiquitous in Japanese society, deeply embedded in the daily lives of people from all walks of life. One of the most prominent places you will hear this word is within the Japanese educational system, specifically in the context of extracurricular club activities known as 部活 (bukatsu). In middle schools, high schools, and universities across Japan, students dedicate countless hours after school and on weekends to their chosen clubs, whether they are sports teams like baseball, soccer, and volleyball, or cultural clubs like brass band, choir, and drama. In these environments, the word 練習 (renshuu) is chanted, scheduled, and discussed constantly. Coaches will demand rigorous 練習, senior students (senpai) will guide junior students (kouhai) through their 練習 routines, and students will often excuse themselves from other social obligations by simply stating, '今日、練習がある' (Kyou, renshuu ga aru - I have practice today). The culture of relentless practice is a cornerstone of Japanese youth development.

School Clubs (Bukatsu)

Extracurricular activities are the primary domain of this word for young people. It represents dedication, teamwork, and the pursuit of excellence through repetition.

Beyond the schoolyard, you will frequently encounter this word in language schools and educational settings geared towards adults. If you are attending a Japanese language school, your sensei (teacher) will undoubtedly use this word to instruct you. They might say, '隣の人と会話を練習してください' (Tonari no hito to kaiwa o renshuu shite kudasai - Please practice the conversation with the person next to you). In this context, the word bridges the gap between theoretical knowledge and practical application. It is the active process of moving a grammar point from a textbook into spoken reality. Similarly, in English conversation schools (eikaiwa) across Japan, Japanese students are constantly encouraged to 練習する their English pronunciation and listening skills. The word serves as a call to action, reminding learners that language acquisition requires active, vocal participation rather than just passive reading.

Language Learning

Teachers use this verb to instruct students to actively engage with the material, such as speaking out loud, writing kanji, or role-playing conversations.

Another common setting is in the realm of music and the performing arts. Walk past any music studio, karaoke box, or even a park on a weekend, and you might hear someone practicing an instrument or singing. In Japanese, taking lessons for a hobby is very common, and these are often referred to as 習い事 (naraigoto). Whether it is a child taking piano lessons or an adult learning the shamisen, the time spent between lessons perfecting the craft is described as 練習する. You will hear parents telling their children, 'ピアノを練習しなさい' (Piano o renshuu shinasai - Practice the piano!). Professional musicians and actors also use this word extensively when preparing for concerts or plays. The concept of the 'rehearsal' is closely tied to this, though the specific loanword リハーサル (rihaasaru) is also used for the final run-throughs before a performance.

Driving Schools

In Japan, getting a driver's license requires rigorous practical training at a driving school, where the physical act of driving is constantly practiced.

Finally, the corporate world is not exempt from the concept of 練習する. While business professionals might use more formal terms for training, such as 研修 (kenshuu), the word 練習する is still heavily used when preparing for specific, skill-based tasks. For example, before a major presentation to a client, a team might gather in a conference room to 練習する their pitch. A new employee working in retail or hospitality will 練習する the standard greetings and bowing angles required for customer service. Even the act of exchanging business cards (名刺交換 - meishi koukan), which has a strict etiquette in Japan, is something that fresh graduates will 練習する repeatedly until it becomes second nature. In all these contexts, the word signifies a humble dedication to improvement and a desire to perform flawlessly when it matters most.

When English speakers learn the Japanese word 練習する (renshuu suru), they often map it directly to the English word 'practice'. While this is generally an accurate translation, the boundaries of usage in Japanese are stricter, leading to several common mistakes. The most frequent error is confusing 練習する with 勉強する (benkyou suru), which means 'to study'. In English, a student might say, 'I need to practice my math,' meaning they need to do math problems to study for a test. If you translate this directly to 数学を練習する (suugaku o renshuu suru), it sounds very strange to a Japanese ear. Math is an academic subject that requires cognitive understanding and problem-solving, which falls under the domain of 勉強する. 練習する is reserved for physical skills, muscle memory, or performative actions. You practice pronunciation, you practice writing kanji strokes, you practice a speech, but you study grammar, history, and mathematics.

Study vs. Practice

Never use 練習する for academic subjects like math, science, or history. Use 勉強する (benkyou suru) instead. 練習する is for skills.

Another common pitfall involves the concept of 'practicing' a profession. In English, we say that a doctor 'practices medicine' or a lawyer 'practices law'. This usage of the word practice implies engaging in a profession actively. If you attempt to translate this into Japanese using 練習する, for example saying 医者が医学を練習する (Isha ga igaku o renshuu suru), it completely changes the meaning. It sounds like the doctor is a student doing drills or rehearsing how to be a doctor, rather than actually performing their professional duties. In Japanese, to express practicing a profession, you would use verbs like 営む (itonamu - to run a business/practice), 従事する (juuji suru - to engage in), or simply state their profession using です (desu) or やっている (yatte iru - is doing). 練習する strictly implies a state of learning or preparation, not the final, professional execution of a duty.

Professional Practice

Do not use 練習する to mean 'working as a professional' (e.g., practicing law). It only means practicing to improve a skill.

Particle mistakes are also quite frequent among beginners. Because 練習する is a suru-verb, it is essentially the noun 練習 combined with the verb する. When specifying what you are practicing, you must use the object particle を (wo). For example, ピアノを練習する (piano o renshuu suru). A common mistake is using the particle が (ga) or に (ni) incorrectly. Saying ピアノが練習する (piano ga renshuu suru) grammatically implies that the piano itself is doing the practicing, which is nonsensical. Furthermore, some learners try to separate the noun and the verb with a particle when it is not necessary, or they double up on the を particle. For instance, saying ピアノの練習をする (piano no renshuu o suru) is perfectly correct and means 'to do piano practice', but saying ピアノを練習をする (piano o renshuu o suru) is grammatically incorrect because you cannot have two direct objects marked by を in the same clause.

Double Particle Error

Avoid using the object particle を (wo) twice in a single clause when using suru-verbs.

Lastly, learners sometimes confuse 練習する with 復習する (fukushuu suru), which means 'to review'. If a teacher tells you to go home and review the lesson, they will say 復習してください (fukushuu shite kudasai). Reviewing involves looking over notes, re-reading texts, and solidifying memory of what was taught. Practicing (練習する) involves actively doing the skill. While reviewing might involve some practice, the terms are distinct. If you tell your teacher you 'practiced' the textbook (教科書を練習しました), it sounds odd. You should say you reviewed it (教科書を復習しました). Understanding these subtle distinctions will significantly improve the naturalness of your Japanese and prevent confusing miscommunications in educational and professional settings.

While 練習する (renshuu suru) is the most common and versatile word for 'to practice' in Japanese, the language boasts a rich vocabulary of similar words and alternatives that offer more specific nuances depending on the context. Understanding these alternatives allows you to express yourself with greater precision and cultural awareness. One of the most culturally significant alternatives is 稽古する (keiko suru). While it translates to 'practice' or 'training', 稽古 is almost exclusively used in the context of traditional Japanese arts and martial arts. If you are practicing Judo, Kendo, Tea Ceremony (Sado), Flower Arrangement (Ikebana), or traditional theater like Kabuki or Noh, you do not typically use 練習する; you use 稽古する. The word 稽古 carries a deeper sense of discipline, respect for tradition, and spiritual refinement that goes beyond mere physical repetition. It implies learning from the past and honoring the lineage of the art form.

稽古する (Keiko suru)

Used for practicing traditional Japanese martial arts (Budo) and cultural arts (Geido). It implies a deeper, more disciplined form of training.

Another important alternative is 訓練する (kunren suru), which translates to 'to train' or 'to drill'. This word is used in contexts that are more formal, rigorous, and often related to safety, emergency preparedness, or professional duty. For example, military training, fire drills, and guide dog training all use the word 訓練. It implies a systematic program designed to instill specific, often life-saving or highly technical, behaviors and responses. You would not use 訓練する for practicing the piano, as it sounds far too militant and serious. Conversely, if you want to emphasize the intensity of a sports practice, you might use the word 特訓する (tokkun suru), which means 'special training' or 'intensive training'. This is often used in anime or sports manga when a character undergoes a grueling, specialized regimen to overcome a specific weakness or prepare for a major rival.

訓練する (Kunren suru)

Used for practical, professional, or emergency training. Examples include military drills, disaster preparedness, and animal training.

In academic and professional settings, you might encounter 演習 (enshuu). This word translates to 'exercises', 'seminar', or 'maneuvers'. In a university context, an 演習 is a seminar class where students actively participate, discuss, and practice applying theories, as opposed to a passive lecture (講義 - kougi). In a military context, it refers to field maneuvers or tactical exercises. For everyday language learners, it is also crucial to distinguish 練習する from 学ぶ (manabu - to learn) and 習う (narau - to take lessons in). 習う implies that you are receiving instruction from a teacher (e.g., ピアノを習う - taking piano lessons), whereas 練習する is the individual effort you put in outside of those lessons to improve. 学ぶ is a broader, more abstract term for acquiring knowledge or wisdom, often through experience or deep study, rather than just repetitive physical practice.

特訓する (Tokkun suru)

Intensive, special training. Often used when cramming or doing a boot-camp style practice session to rapidly improve.

Finally, the English loanword トレーニング (toreeningu - training) is very commonly used in modern Japanese, particularly in the context of fitness, gym workouts, and sports science. If you are lifting weights or doing cardio, you are more likely to say トレーニングをする rather than 練習する. 練習 implies practicing a specific skill or technique (like a tennis serve or a soccer pass), while トレーニング focuses on building the physical body, strength, and stamina required for that sport. By carefully selecting between 練習, 稽古, 訓練, 特訓, and トレーニング, you can convey exactly what kind of practice or training you are undertaking, demonstrating a high level of fluency and cultural competence in Japanese.
