WaniKani vs MaruMori (2026): kanji specialist or all-in-one course?

Short answer: pick WaniKani if the only thing standing between you and reading Japanese is kanji, and you want the best-drilled path through 2,000 of them. Pick MaruMori if you are still assembling a course — grammar, vocabulary and kanji in one place — and you do not want to run three subscriptions to get there. Neither of them will ever read a Japanese sentence you wrote and tell you what is wrong with it.

I build BetterLingo from Japan, and I have used both of these the way a learner does — every morning, on a phone, on the train — rather than the way a reviewer does, clicking through a first session and writing it up. This page says what each one is genuinely better at, and it says what BetterLingo is not, near the bottom, because a comparison written by a third product is worthless if it hides that part.

Why this page exists

Search wanikani vs marumori and page one is the WaniKani community forums, the Bunpro forums and Reddit — good threads, many of them, but all of them answering half the question for one person who asked it in 2023. MaruMori has changed a lot since most of those were written. The question keeps getting asked and keeps getting answered in fragments, which is a different problem from nobody asking it.

What WaniKani is better at

  • One job, done properly. WaniKani teaches radicals, then the kanji built from them, then the vocabulary built from those kanji, in a fixed order across 60 levels. That constraint is the product. You never choose what to study next, which means you never spend a morning tuning a deck instead of using one.
  • The mnemonics actually work. Tofugu writes a story for every radical, kanji and reading, and the stories reuse each other's characters so they compound. This is the part people underestimate until about level 15, when the kanji stop looking like each other.
  • Readings are drilled, not decorative. WaniKani makes you type the reading in kana, not recognise it in a multiple choice. That is a harder question than most kanji apps ask, and it is the one that transfers to reading.
  • Fifteen years of community. The forums have a thread for nearly every wall you will hit, level-by-level vocabulary lists, book clubs, and a userscript ecosystem that fixes most of what people complain about.
  • It ends. Level 60 is a defined finish line covering roughly the jōyō set. Very few Japanese study tools ever tell you that you are done.

What MaruMori is better at

  • It is a whole course, not a component. Grammar lessons, vocabulary SRS, kanji SRS and reading practice sit in one app that knows what you have already learned. WaniKani plus a grammar tool plus a vocabulary deck is three products that each assume they are the only one you use.
  • Grammar is first-class. WaniKani has none at all — deliberately. If you are below roughly N4 and still learning how sentences are put together, that gap is the whole problem, and MaruMori is built around filling it.
  • You are not locked to one order. MaruMori lets you learn kanji alongside the vocabulary and grammar that need them, rather than waiting for a level gate to release a character you met yesterday in a book.
  • The free tier is genuinely usable. You can get a real sense of whether the system fits you before paying anything, which is not true of most all-in-one Japanese apps.
  • It is actively built. MaruMori ships changes often and its roadmap is public. WaniKani is stable, which is a virtue, but stable means the thing you wish it did is probably not coming.

Where each one will annoy you

WaniKani is rigid on purpose, and the rigidity bites in three places: you cannot skip kanji you already know without burning through levels, you cannot add a word you met in the wild, and if you miss a week the review pile that greets you is genuinely demoralising. It is also kanji-shaped — it will not teach you a single grammar point, and its vocabulary exists to reinforce kanji rather than to cover what you need to say.

MaruMori is younger and smaller, and that shows in scope rather than quality: fewer years of community threads to search when you are stuck, a smaller body of third-party material built around it, and a kanji path that has not been sanded down by a decade of people complaining about level 12. Doing four jobs also means it is not the single best tool at any of them — WaniKani's kanji drilling is more refined, and dedicated grammar SRS tools go deeper on grammar.

How to actually choose

  • You can already handle basic grammar and reading is what stops you. WaniKani. Add a grammar tool separately if you need one.
  • You are starting from near zero, or from Duolingo. MaruMori. One structured path beats three half-used subscriptions.
  • You are studying for a specific JLPT sitting. Neither is a JLPT course. Both help; both will leave you doing exam-shaped practice somewhere else. See Bunpro vs MaruMori and Bunpro vs WaniKani for the grammar-drill side of that decision.
  • You want to own your reviews forever. Neither. That is Anki's argument, and it is a real one.
  • You bounced off WaniKani's order once already. MaruMori, or one of the other options in WaniKani alternatives.

The gap both of them leave

WaniKani and MaruMori are recognition systems. They show you something and ask whether you know it. That is the correct way to build a vocabulary and it is most of what an SRS can do — but it is the easier half of knowing Japanese, and it is not what a JLPT reading passage or a real conversation asks of you.

Neither app has ever read a sentence you wrote. Neither can tell you that your て-form is fine but your particle turned the sentence into something nobody would say, or that the grammar is correct and the register is wrong for who you were talking to. That feedback normally requires a tutor, and a tutor is the most expensive hour in Japanese study.

What BetterLingo is, and what it is not

BetterLingo is a JLPT practice site that marks written answers: you write Japanese, it says what is wrong and why, in English, and you fix it. You can try that on the free sentence checker — or the て-form and particle pages, which are the two things it gets asked about most — without an account.

Now the honest part. BetterLingo is small and new. It has no mnemonic system and nothing like WaniKani's fifteen-year community. It has no shared-deck library, no mobile app, and no full beginner curriculum, so it will not replace MaruMori for someone starting from zero. If you want a kanji path to walk for the next two years, that is WaniKani or MaruMori, not this. What it does that neither does is grade production rather than recognition — and that is a complement to both of them, not a substitute.

Next steps

If you are already deep into WaniKani or MaruMori, keep going — switching kanji systems mid-stream costs more than it returns. The useful addition is production practice, so pick one sentence you are unsure about today and get it marked, rather than adding a fourth recognition tool to the pile.
