WaniKani for Japanese: Is It Worth It? An honest review — and what it leaves out
If you are weighing up WaniKani for learning Japanese, here is the honest version: WaniKani is one of the best tools in existence for learning to read kanji, and that is the one thing it does. It will not teach you grammar, listening, or speaking. So whether it is "worth it" depends entirely on what you need it to do.
This is an honest look at what WaniKani does brilliantly, what it deliberately leaves out, and what to use if you want a complete path to actually using Japanese.

Is WaniKani worth it for learning Japanese?
For what it sets out to do, WaniKani is excellent, and it has earned its loyal following:
-
✅
Best-in-class kanji learning. It uses radicals (the building blocks of characters) and memorable mnemonics to teach over 2,000 kanji and around 6,000 vocabulary words.
-
✅
Spaced repetition done well. Its SRS schedules reviews at the right moment so the kanji actually stick long-term.
-
✅
A clear, gamified path. Sixty levels give a strong sense of progress that keeps people coming back.
-
✅
An active, supportive community.
If your single goal is to read kanji, WaniKani is genuinely hard to beat.
What WaniKani leaves out
The catch is that WaniKani is a kanji and vocabulary trainer, not a Japanese course. By design, it does not include:
-
✗
No grammar at all. WaniKani never teaches you how to build a sentence. You can know hundreds of kanji and still not be able to say or understand a full thought.
-
✗
No listening or speaking. It is reading-recognition only, with no conversation or pronunciation practice.
-
✗
No JLPT-structured course. Its kanji order is its own, not aligned to JLPT levels, so it is not a study path for the exam.
-
✗
Fixed pacing. The SRS gates how fast you can move, which some learners find slow.
This is why you will see WaniKani fans say the same thing: it is a tool you use alongside other resources for grammar, listening, and speaking, not on its own.
So is WaniKani enough to learn Japanese?
No, and it is not meant to be. WaniKani is worth it as a dedicated kanji tool if you are willing to add a separate grammar course, listening practice, and speaking practice on top. If you would rather not stitch several subscriptions together, you want one platform that covers all of it.
A complete alternative: Nihongo Master
Nihongo Master gives you WaniKani's strength — kanji and vocab through spaced-repetition drills — plus everything WaniKani leaves out, in one place:
-
✅
Kanji and vocab with spaced-repetition drills and a built-in kanji dictionary with stroke order and audio.
-
✅
Real grammar lessons that explain the why, which WaniKani has none of.
-
✅
A JLPT-aligned path from N5 through N1, so you follow a real course, not just vocabulary lists. (Check your level with the free JLPT N5 practice test.)
-
✅
Printable handwriting practice sheets and an active community.
-
✅
One subscription instead of paying for several tools.

Who should pick which?
Pick WaniKani if…
your only focus is kanji, and you already have grammar, listening, and speaking covered by other resources.
Pick Nihongo Master if…
you want one complete path — kanji and grammar and a JLPT structure — without assembling and paying for multiple tools.
Many learners pair them: use Nihongo Master as the core course, and add WaniKani if you want extra kanji depth.
The bottom line
WaniKani is the best kanji-only tool out there, and worth it if kanji is exactly what you need. But reading kanji is only one piece of learning Japanese. If you want grammar, a JLPT path, and everything in one place, Nihongo Master is built for that — and you can try it free.

Frequently asked questions
Is WaniKani worth it?
If your goal is to learn to read kanji, WaniKani is worth it. Its radical-and-mnemonic SRS system is one of the most effective ways to memorize kanji. It is less worth it as your only resource, because it does not teach grammar, listening, or speaking.
Is WaniKani enough to learn Japanese?
No. WaniKani only covers kanji and vocabulary. To actually use Japanese you also need grammar, listening, and speaking practice, so WaniKani works best alongside a full course rather than on its own.
Does WaniKani teach grammar?
No. WaniKani teaches kanji and vocabulary only and has no grammar lessons. You will need a separate grammar resource, or an all-in-one course that includes it.
What is a good WaniKani alternative?
For an all-in-one option, Nihongo Master covers kanji and vocab with spaced-repetition drills and adds the grammar lessons, JLPT-aligned path, and dictionary that WaniKani lacks, in a single platform.
Is WaniKani free?
WaniKani's first three levels are free, after which it requires a subscription (about $9 per month) or a lifetime purchase. Nihongo Master offers a free trial and a free tier so you can compare them yourself.
