About this app

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.

honestly, better than Duolingo. you learn Kanji as you learn words, so you get used to reading it. not to mention, there are games you can play to reinforce your vocabulary that are actually fun (unlike most edutainment)! i recommend at the very least giving it a try if you want to learn Japanese, and you can set your current skill level right from the start.

Thanks! We're 100% focused on Japanese, so most of renshuu's functionality is built with Japanese in mind, and not a "generic product" that you can plug any language into. If you need anything as you learn on renshuu, do let me know. I'm always here at michael@renshuu.org, or the ? button at the top of the app!

So far, this has been much better than Duolingo, which I used a couple years back. instead of throwing random exercises and words at you, renshuu actually teaches you the Japanese alphabet first. The memorization is a little rushed in my opinion (new characters to memorize every day) but I've gained a solid understanding of Hiragana, soon to move into Katakana. I would definitely recommend this app for anybody attempting to learn Japanese.

Thanks for the feedback! If you tap the ... next to the schedule, then go to Pace, you can fully customize how quickly (or slowly) the new materials come in :). Just about everything can be customized in renshuu! If you need anything as you learn on renshuu, do let me know. I'm here at michael@renshuu.org, or the ? button at the top of the app!

If your goal is to learn Japanese alone, this is a far better option than Duolingo. The app is run by a very small team, but there is far more community engagement, and the flashcards leave a much larger inpression than Duo's monotony and repetition. I have been using the app for about a week and I already can remember the hiragana alphabet better than my 100+ days of Duolingo. The UI is a work in progress but trust me, the experience is friendlier and seems more attuned to my needs.

The UI will always be a work in progress (laughs) - due to the huge amount of content, functionality, and customization, there will always be more visual friction. Not to say that I am not continually working on improvements, of course :) If you need anything as you learn, I'm here at michael@renshuu.org, or the ? button at the top of the app!
