Duolingo is the most downloaded language learning app in the world. Over 120 million people use it to study nearly 30 different languages.

Last month, they finally released their long-awaited Japanese version!

Apparently, Japanese was the most requested language ever on Duolingo. We couldn’t wait to test it out and try it for ourselves.

Read our Duolingo Japanese review and see if this could be the right way for you to learn Japanese!

Getting started with Duolingo

Duolingo is an app which is free to download and use. You can get it from the App Store or Google Play.

By the way, you can study other Duolingo language courses online through their website. But the Japanese course is currently only available on the app.

When you download the app you’ll be asked to choose how much time you can spend on Japanese each day. The options are 5 minutes, 10 minutes, 15 minutes or 20 minutes. All nice and achievable!

This is important because the app will remind you to stick to your commitment each day. You’ll get notifications, and there’s also a streak counter within the app. Once you’ve built up your ‘streak’ by studying for several days in a row, you won’t want to break it!

Building up a regular habit is so important in language learning. 5 or 10 minutes a day might not sound much, but stick to this over time and you’ll see results.

Next, you’ll be asked to pick your level. You can start as a complete beginner, or take a placement test. The full Duolingo Japanese course goes up to around JLPT level 5.

You can always go back to any previous level, but you can’t check out higher levels without passing the placement test!

Learning Japanese with Duolingo

Duolingo is a gamified, intuitive way to learn a language.

There are no typical ‘lessons’ like you would have in a traditional language learning course.

There are no explanations of grammar or new concepts. In fact, there’s almost no English used.

Instead, you learn Japanese through examples.

The app introduces one or two new words at a time. New words are introduced with pictures. You complete lots of activities and games using these new words until they stick in your memory.

The activities fall into a few categories. There’s this one, where you click on word tiles to translate a sentence:

This sentence building activity is really fun and easy to use. It’s also addictive!

Then there’s the reverse activity, where you see a sentence in Japanese and have to type in the answer in English.

And this one, where you tap on tiles to select matching pairs:

These kinds of activities are so quick and fun to do. Each lesson or level is very short. This means it’s easy to get addicted to language learning. You might start off with a goal to study just five minutes each day, but once you start, you’ll find yourself doing ‘just one more lesson’ over and over!

Does Duolingo teach you to read and write in Japanese?

Yes, it does. The Duolingo Japanese course teaches you to read hiragana, katakana, and about 90 essential kanji. You should know enough kanji to pass the JLPT N5 test if you complete the Duolingo Japanese course.

The very first thing you will learn on the Duolingo course is hiragana. Then they introduce katakana and kanji slowly throughout the rest of the course.

The course doesn’t use any English or romaji at all. All new words are in hiragana, until you learn the kanji for them. This means you have lots of reading practise!

One problem with the Duolingo method is that it doesn’t actually explain the difference between hiragana and katakana.

This is in keeping with Duolingo’s principle of not having any explanations. But I’m not sure it works well for a complicated language like Japanese. If you didn’t already know about the different scripts in Japanese, you would be totally confused when you are taught the character め, pronounced as me, and then メ- another character for me – in the next lesson.

Of course, the first character is hiragana, and the second character is katakana. The makers probably assume you know this. But not all learners will.

This learning style won’t be for everyone. You might be better off learning hiragana and katakana by yourself first, or at the very least supplementing Duolingo with your own reading.

Another issue is that you will only learn to recognise Japanese characters. You won’t learn to write (either by hand, or by computer or phone). If you want to write Japanese by hand, it’s important to learn the correct stroke order when you learn a new character. Duolingo unfortunately doesn’t teach this.

Problems with Duolingo

Unfortunately, there are a few bugs and other issues with Duolingo. The most obvious one is the sound. Most of the tiles say their word out loud when you tap them. However, quite a few of them don’t work. This is an issue because you can’t hear the pronunciation of the full sentence.

More seriously, sometimes the pronunciations are just wrong. In Japanese, there is often more than one pronunciation for a word or character. Duolingo only seems to be able to cope with one pronunciation for each word or character. It can’t tell when the pronunciation should be different, based on the word’s function in a sentence. So は is always pronounced ‘ha’, never ‘wa’. 人is always ‘jin’, never ‘hito’ (or ‘nin’).

There is not even any explanation of how words can sometimes be pronounced differently. If you are a total beginner learning Japanese through Duolingo only, sadly you will learn some incorrect Japanese.

Remember that Duolingo Japanese is still very new. Hopefully they will work on some of these issues for future updates!

It’s also worth mentioning that you can’t turn off the sound. The sound got really annoying once I realised there were so many mistakes, but I couldn’t do anything about it. And don’t forget your earphones if you want to use Duolingo in a public place.

What’s good about Duolingo?

Overall, Duolingo is a really good app.

It makes learning fun. It’s nicely designed. It’s addictive and easy to use.

Features like a streak counter and daily reminders encourage you to study daily – and ‘little and often’ is a very effective way to learn a language! There are a few other cute functions, like the ability to form a language learning group with your friends (or strangers!) to motivate each other and chat about Japanese.

You will learn Japanese words on a variety of topics. The topics switch frequently to keep you interested. There are even special lessons on anime and manga vocabulary, as well as phrases you need for the 2020 Tokyo Olympics.

And by the way, it’s completely FREE. It’s free because it’s funded by ads, which pop up at the end of each lesson. Also, there are optional in-app purchases, such as going ad-free or pausing your streak for a day.

App details

The app is completely FREE and available from the App Store and Google Play. Soon you will be able to access it online (from your desktop) too, for people without a smartphone.

Our thoughts on learning Japanese with Duolingo

Duolingo Japanese is not perfect. But it is a fun and effective way to learn some basic Japanese.

If you really only have five minutes in a day to study, Duolingo is probably one of the most effective ways to spend your time.

But if you have any longer than that, I would recommended using other learning materials instead of (or alongside) Duolingo.

At the very least, make sure you read about the different Japanese writing systems, so that you aren’t confused about how to use hiragana and katakana!

I also recommend getting a lot of audio input elsewhere, since the Duolingo Japanese audio is buggy. You can get FREE, highly recommended audio lessons for all levels here.

If you want a more structured approach to learning – and if your aim is to speak good conversational Japanese, or even become fluent – you need a better quality online course.

  1. I agree with your review of Duolingo for learning Japanese. I wonder if you have reviewed Rosetta Stone? I would be interested in hearing your opinion about that one.

    Thank you for a very useful website!

  2. I had tried duolingo and was not impressed when they used ha as wa when it was not being used in a sentence. They should have used the correct hiragana for wa and not ha. I personally prefer busuu and memrise for the free learning Japanese apps. Busuu, I will pay the premium for since it allows me to have my answers for the lessons read and reviewed by fluent Japanese speakers.

    • im pretty sure that ‘ha’ is pronounced as ‘wa’ when used in particles,
      watashi wa has ha in place of particle

      in all other places where wa is part of word, it is not interchangeable with ha, and duolingo did not mess any of that up

      • Is the wa in kon’nichiwa (こんにちは) a particle as well? I know particles arent in words, but its confusing on how its pronounced wa when it doesnt appear to be a particle

        • ‘Konnichiwa’ is kind of an exception, since nowadays it is considered a standalone word, but it originated as a shortened form of a fuller greeting along the lines of ‘konnichi wa ikaga desu ka’ – ‘how are you today?’. In kanji it would be 今日は. So yes, in こんにちは the は is essentially a particle. Same goes for konbanwa/こんばんは/今晩は – good evening. Apart from these exceptions, は is always pronounced ‘ha’ in words and ‘wa’ as a particle.

  3. Thanks for your review! I am a bit confused because many reviews say that Duolingo is a very bad website to learn Japanese, and is a waste of time. While other reviews complimented Duolingo a lot and said it makes you very good at Japanese. If I am a beginner and hope to learn Japanese as a hobby and be fluent, do you recommend I use Duolingo? Or should I use other websites? If so, do you know any places to learn Japanese without it being very expensive? Thank you so much for your help.
