練習をする

Grammatically, this is a classic 'Noun + を + Verb' combo. 練習 is the thing, を is the finger pointing at the thing, and する is the action of doing it. You’ll mostly see it as 練習をする, but in casual speech, people often drop the を and just say 練習する. However, keeping the を adds a tiny bit of weight and emphasis to the activity itself. It makes it sound like a discrete event you’ve planned. For example, if you say テニスの練習をする (I will do tennis practice), you are treating the 'tennis practice' as a specific block of time. You can put almost any skill-based noun before it using the particle の. So, ピアノの練習をする (to do piano practice) or スピーチの練習をする (to do speech practice) are your bread and butter. If you want to say you are currently doing it, change it to 練習をしています. It’s like telling your friends on Discord, 'Hey, I’m in the middle of a practice session, don’t invite me to the lobby yet!' It’s a very safe, middle-of-the-road phrase that won't make you sound like a robot or a delinquent.

Imagine you’re a gamer. You’ve just downloaded a new fighting game and you head straight into 'Training Mode.' In Japanese, you’d say コンボの練習をする (I’m practicing combos). Or maybe you’re an Instagram influencer trying to get that perfect 'casual' selfie. That mirror session? That’s 自撮りの練習をする (practicing taking selfies). It’s not just for old-school stuff like calligraphy or karate. It’s for the modern world, too. Think about a Zoom call. Before you hop on a big interview, you might 面接の練習をする (do interview practice) with a friend. Even at a karaoke box, if you’re singing the same song five times to hit the high note, you are 歌の練習をする. It’s the universal label for 'I am working on this because I want to be good.' If you see someone at the park kicking a ball against a wall alone, they are definitely 練習をしています. It’s a lonely but noble pursuit. My favorite example is 箸の練習をする (practicing using chopsticks)—everybody has been there, usually at a restaurant where they only have the pointy wooden ones that are surprisingly slippery.

Use this whenever there is a clear goal of improvement through repetition. If there’s a 'drill' involved, this is your phrase. It’s perfect for sports (soccer, baseball, swimming), arts (drawing, dancing, singing), and technical skills (coding, cooking, driving). If you’re telling a coach, a teacher, or a parent what you’ve been up to, this is the most natural way to put it. It sounds productive! You can also use it when you’re apologizing for being bad at something. すみません、まだ練習をしています (Sorry, I’m still practicing) is a great way to lower expectations before you accidentally hit a wrong note or trip over your own feet. It’s also the right phrase for 'mental' practice, like rehearsing a confession to your crush or a tough talk with your boss. If you’re doing it in your head to get it right, it still counts as 練習.

This is a big one: do not use 練習をする for academic subjects like history, math, or science. For those, you need 勉強をする (to study). If you tell someone you’re 'practicing math,' they might think you’re doing some weird physical ritual with a calculator. Also, avoid using it for things that are just 'habits.' You don't 'practice' drinking water or 'practice' sleeping—those are just things you do. Another subtle point: don't use it for heavy-duty military or professional emergency training. Firefighters and soldiers use 訓練 (kunren), which sounds way more intense and life-or-death. If you use 練習 for a fire drill, it might sound like you’re just playing around for fun. Lastly, it doesn't work well for 'experiencing' something. You don't 'practice' a vacation. You enjoy it!

This is the #1 mistake. You can't have two を particles in a row like that—it’s like trying to wear two hats at the same time. It’s confusing! Instead, use の to link the subject to the practice.

You don't 'practice' a test (unless it's a practice exam, but that's a different word). You 'study' for it.

While people might understand you, adding the の makes it sound like a proper 'practice session' rather than just 'doing cooking.'

If 練習をする feels too basic, you can try 稽古をする (keiko o suru). This is used for traditional Japanese arts like tea ceremony, kendo, or calligraphy. It sounds a bit more 'disciplined' and traditional—think Mr. Miyagi vibes. Then there’s トレーニングをする (training o suru). This is almost exclusively for physical fitness or gym-related work. If you say this, people will assume you’re lifting weights or running marathons. Another one is 反復する (hanpuku suru), which means 'to repeat.' It’s more technical and less common in daily life, but you might hear it in a music lesson where the teacher wants you to do the same scale ten times. Finally, 予習 (yoshu) and 復習 (fukushu) are for 'preparing' and 'reviewing' lessons, which is like the academic version of practice.

In the wild, you’ll hear 練習中 (renshu-chu), which means 'currently practicing.' You’ll see this on signs at a piano room or as a status on a gaming profile. It’s short and punchy. There’s also 猛練習 (mou-renshu), which means 'intense/fierce practice.' Use this if you’re trying to master a skill in three days for a talent show and you haven't slept. If you want to talk about the *result* of practice, you’d say 練習の成果 (renshu no seika). And if you’re just doing a 'warm-up,' that’s 準備練習 (junbi renshu). Sometimes people say 練習台 (renshu-dai), which means a 'practice target' or 'guinea pig.' Don't be someone's 練習台 for a new haircut unless you really trust them!

Is 練習する different from 練習をする?

Practically, no. Dropping the を is just more casual and faster to say. It’s like saying 'I’m practicing' versus 'I’m doing my practice.' Most people use the short version in daily life, but the long version is better for writing or being clear.

Can I use it for learning a language?

Yes! 日本語の練習をする is very common. It means you’re actually speaking or writing, not just staring at a textbook. If you're on Duolingo, you're definitely doing 練習.

What if I'm practicing a hobby?

As long as there's a skill to improve, it works. Whether it's knitting, gaming, or TikTok dances, 練習をする covers it all. If you can get better at it, you can 'renshu' it.
