Hello everyone!
We’ve made a website called Asoi that creates simple Japanese learning games using your WaniKani vocabulary.
About the Project
Asoi is meant to be a quick and easy way to reinforce what you’ve already learned - without adding another full SRS system to your routine. It’s great for when you have a few minutes to spare or just want a break from regular reviews.
Recall – Practice recalling Japanese words from English meanings
Word Split – Identify word boundaries in text without spaces
Memory Match – A classic matching game with your vocabulary
Jordle – A Wordle-inspired game for Japanese readings
Word Search – Find your vocabulary in a grid of characters
How It Works
You can connect your WaniKani API key or upload your own vocabulary list. The games use words you already know, so you’re reinforcing existing knowledge instead of learning new material. Please note that the site is not fully optimized for mobile yet.
Development Status
We’re still working on developing and improving Asoi. Since we’re both students learning Japanese and software development, there will be occasional issues, but we’re actively working on fixing them all!
If you’d like to check it out, you can find it at Asoi.io. If you run into any problems or have suggestions, we’d love your feedback!
We hope some of you will try it out and find it useful!
Thank you for creating this! This is something I’ve really needed was to having the words I’m studying on WK be put into fun games! I personally love word searches and crosswords a lot!
Thanks, we very much felt the same way! We hope everything’s working well for you, but if you run into anything that needs fixing or have suggestions for improvements, feel free to let us know!
Maybe look into the Japanese language learning video games Nihongo Quest N5, Koe 声, Shujinkou, and Wagotabi to get other ideas on games that could be created to test one’s WaniKani knowledge.
Thank you! The Recall game should be completely random, but we might have messed something up in the logic. We’ll take a look and post an update when it’s fixed!
Thanks for the feedback! Since the game pulls vocabulary directly from WaniKani, it only accepts the specific answer WaniKani assigns (in this case, きぶん for ‘feeling/mood’). We may look into supporting alternative correct answers in the future!
Like in wanikani when you see 少女、女の子、女子 you can type in “girl” and be correct for all of them. Meanwhile this game when asking for “girl”, only sees one of those three as correct.
Oh, I get it now! I hadn’t really noticed since I’m not that high level yet, so I didn’t run into this issue as much. I’ve made some changes, and it should hopefully now accept multiple correct answers like WaniKani does. It at least works for “girl” now! The site only uses vocabulary words, so readings or kanji that appear in compounds might not always be accepted as standalone answers though. Let me know if you run into any other cases where it doesn’t work as expected!
This is a good idea. I knew of KaniWani and the other one, but already going to Japanese classes, doing homework, plus Wanikani and Bunpro, plus doing reading and listening, another full SRS is completely overkill (and I don’t think this reverse learning is something that needs to be done regularly anyways). However a game that you can play when you have time is cool. I also like a lot this conjugation practice: Japanese Conjugation Practice, maybe you can add a similar game for the verbs already studied on Wanikani.
