A cute, ad-free, and enjoyable learning experience is waiting for you in the Renshuu community! The free version is unlimited: there’s no timer before you are forced to pay!

- A path for every learning style and every goal -
Whether you are getting started with the alphabets or have been studying for years, jump in exactly where you belong! Don’t waste time going through what you already know.

Renshuu maintains learning paths for most textbooks, the JLPT, Kanji Kentei, and for those who just want to learn. You can also carve out your own path! Our community has over 10,000 user-made lessons for even more focused learning.

- Cute, relaxing, and fun -
Our mascot Kao-chan is here to let you enjoy learning Japanese, whether it’s through collectible coins every time you quiz, a character that evolves as you learn, manga pages that you unlock, or hundreds of hand-made illustrations.

Additionally, we have both single and multiplayer games to help you keep your learning and reviewing fresh!

- Personal service -
We are just a two-person company - and we don’t use chat bots. That means that every question you have gets an answer directly from us.

- Rich, in-depth materials -
> Vocabulary: over 15,000 native-recorded audio files, 17,000 hand-picked images, and 160,000 example sentences make understanding vocabulary a breeze. Our growing library of accent/pitch data can even help you with accent reduction.
> Kanji: 12,000+ kanji, with no limits on what you can study! Over 2,000 colorful mnemonics help you to understand and retain the meanings.
> Grammar: Over 800 different expressions, each complete with native-written model sentences, construction diagrams, audio, and over 7,500 hand-made quiz questions.
> Sentences: Thousands of sentences complete with audio, divided by theme and difficulty levels.

- A superior quiz system designed around Japanese -
Our SRS-for-Japanese system doesn’t treat Japanese materials like flashcards to be memorized, and breaks every item down into individual components so you can understand, and not just memorize. Mastery schedules keep you studying only what you need to, pushing weaker materials to the front for you to focus on.

Dozens of different question styles keep things fresh, while a flexible input system (multiple choice, typing, or writing) lets you answer the way that you want to.

- Customizable down to the last character -
Renshuu doesn’t believe that there is a single way of studying that everyone should adhere to. Our expansive settings and customizations let you adjust the learning environment to what works best for you.

So helpful

Renshuu is an amazing way to start learning Japanese, and continues to be helpful as you get better. It’s fun and interactive, and the developer is kind and easy to contact. You can choose exactly what you want to work on and the games help you learn new words alongside digging up old ones you haven’t thought about in a while. The question center has you write based on a prompt, and output isn’t something you see often in language learning programs. My only issue is that it doesn’t seem like you can make all the Japanese to English multiple choice questions show the kanji instead of the furigana when the lesson isn’t specifically on kanji, but that might just be a setting I’m missing and it doesn’t take away from the usefulness of this app. From learner to learner, you won’t be able to learn everything from a single source, no matter how amazing renshuu is, so if you’ve been looking for something that will teach you Japanese by itself, like I did when I was first getting started, that’s not going to happen. I highly suggest doing other things alongside renshuu, like watching videos and plays originally in Japanese without any subtitles, talking to fluent Japanese speakers, writing short stories in Japanese, and recording yourself talking about something you like in Japanese. All in all, I recommend renshuu to any beginner who wants a steady way to learn Japanese. Just don’t use this or anything else as your only resource.

Developer Response ,

First off, thank you so much for your extensive review - it is really appreciated!

Next, I have good news for you! Just about everything in renshuu can be adjusted, and kanji is no exception. renshuu's "default mode" is to show you furigana for kanji you haven't studied in renshuu, so you are not hit with kanji you don't yet know.

If you want to change that, though, you can! Pop open the menu, tap the settings icon, then go to the Vocabulary category. You should see a "What do you with kanji you don't know" setting - change that so it is the far right "kanji only" option. This will ignore your kanji level, and show them to you regardless.

Should this not be a fit for what you're looking for, please reach out to me so I can consider updating the setting! I'm always here at or the ? button at the top of the app.

百万★/五★ I’M IN LOVE!!!!♥︎♡♥︎♡

I am SHOCKED at how well rounded and IN DEPTH this app is!!! I used to have to use seperate resources for: kanji, mnemonics, pitch accent, grammar, vocabulary, sentence mining, flash cards, writing practice, Dictionary, Native Pronunciation, sentence closing, games (for learning) AND Genki Textbook Exercises! But RENSHUU HAS IT ALL!!!! and MORE!! (Not to mention a cute UI which is just icing on the cake!) They also offer learning schedules that are tailored to the textbook you’re in!! This is really great for self study, as I sometimes get bored with studying the Genki Textbooks alone. I can even select their Tobira Textbook (intermediate) learning schedule for after I finish Genki (beginner)!! Like this is an app that can grow with you!! Unlike other apps, that feel like I’m getting an IV drip of Japanese, I can change the settings for a much more immersive and in-depth study. (Changing my study from IV drip, to a more adventurous, white water rafting/white rapids) As a person with ADHD, I’ll be surprised if I get bored with this app because they have so much to offer!! (There’s even an lively and interactive community through the forums!) A million/5 stars! Highly recommend for anyone who wants to become fluent and who also enjoys in depth studies!!! WHY DOES NO ONE TALK ABOUT THIS APP/WEBSITE?!♥ I wish I had found it sooner!!!

Thank you so much - while I might be biased, I really feel that renshuu works great for people as long as they are with it long enough to adjust things to fit them best :)

We've got tons more planned, so I hope you look forward to what is coming up soon!

And of course, I am always here should you need anything at all. You can drop me a line at, or through the ? button at the top of the app.

🙌 Amazing 🙌

This is literally the best Japanese learner app I have ever used. I’ve had my fair share too, about 7 apps I believe. This one is user friendly and very helpful. I’ve been trying to stay constant with learning Japanese and have always failed because the apps don’t do as much for me, I saw this while looking for an app and decided to give one more shot. First time I opened it I was already in awe. I love the program and how simple it is. There are mini games, organized lessons, illustrations, and more!! It is all basically free which is a HUGE bonus!!! There is an optional pro feature, which I have yet to test out, that does cost money. The developer is so very friendly, he responds individually without bots or anything else. He is very nice and I can tell he takes a lot of pride in his work he has done. I am so sad I haven’t figured this app out before, it is literally the best. I need more words to awe over this app! I’ve been using it for about 3 days now and 20/10!! Love love love it! Thank you so much for creating such an app that is free and helpful! That is all I’ve been looking for!
If anyone is reading down to this point, then get this app! It is worthwhile I promise you!!!

You are too kind to leave such a nice review, thank you!

There is indeed a ton packed in there, so I wouldn't be surprised if you are finding new learning goodies even after using it for weeks!

Of course, if you can't find something, just let me know! I'm always looking to make it better, and I enjoy hearing from learners on renshuu. You can always reach me at, or Help > Contact in the app's menu.

Good luck with your Japanese!
