As an avid Japanese learner, I always wanted there to be a simple online trainer for learning kana, kanji and vocabulary by JLPT level. The app serves as a simpler alternative to Chase Colburn’s Kanji Study app, because Kanji Study was pretty complicated for me to use as a beginner and didn’t have a more streamlined way of learning kanji through simple, continuous repetition and rote memorization (also, Kanji Study requires you to pay to unlock its full content library).
So, I started working on a brand new, completely free and fully open-source app in recent months. It’s very new and still in its infant stages, but here are the features so far:
-
Full JLPT vocabulary and kanji coverage, with more than 1000+ levels for you to play
-
More than 25+ different fonts and font styles
-
More than 100+ different color themes, with the ability to add and upload your own custom backgrounds
-
100% free and open-source, forever
-
All learning materials 100% AI-free, sourced from reputable sources and available for full download and inspection
If that sounds interesting to you, you’re welcome to try it out and provide some feedback:

ありがとうございます!
I’ll definitely give this a try, hoping it works for both Windows and Linux. This could potentially become a great mobile app that could challenge Duolingo. As a teenager, I lost my ability to speak, including Japanese and sign language. However, I managed to relearn English within a few months. Unfortunately, I never had the time to relearn Japanese until now.
This is cool and I will try it out. Where did you get the data?
I once made a very simple “service” that provides me with Kanji and word of the day (and can be integrated elsewhere with a very simple “API”), https://plexsheep.github.io/sennen/index.html
I should revisit that some time, the detail view is a bit broken on mobile. And the Furigana is hacky and sometimes wrong.
Just played it for a while and it was quite fun and engaging. Also it felt very playfull without it being childish. Good on you! And thank you for making this.
Is this project at all related to the similarly-named Kanji Dojo? . I’ve been using that one for a while to improve my written Japanese, and I think I’ll fold yours into the mix of apps I’m using as well, looks great!
Replacing Duolingo has been tough on me 😔
I actually need to pick up some basic Japanese and was looking for something like this! This is great, thank you!
Learning Japanese I think I’m learning Japanese I really think so
Cute, fun. Thanks for this!
This is certainly interesting for those learning Japanese. I can’t see myself going to Japan sometime in the future due to what’s going on over there (mainly, the MyNumber program).
