WaniKani vs Anki for Learning Kanji: Which One Should You Use?

Almost every learner hits the same wall: hiragana clicked, katakana clicked, and then 2,000+ kanji stand between you and reading anything real. Two tools dominate the conversation about crossing that wall — WaniKani and Anki. They both use spaced repetition. That’s where the similarity ends.

Short answer: WaniKani is a curriculum. Anki is a machine. WaniKani decides what you learn, when you learn it, and how you remember it. Anki does whatever you tell it to do and nothing more. If you want to stop making decisions and just show up, take WaniKani. If you want total control — and you’ll actually use it — take Anki. Below is how each one really behaves day to day, so you can pick once and stop researching.

The one-minute comparison

How WaniKani actually works

WaniKani, made by the team behind Tofugu, breaks kanji into radicals — visual components, some with names invented purely to make mnemonics work. You learn the radicals first, then the kanji built from them, then vocabulary words that use those kanji. Nothing unlocks until its parts are locked in.

Take 明 (mei / akarui, “bright”). WaniKani teaches 日 (sun) and 月 (moon) first, then hands you 明 with a mnemonic along the lines of sun plus moon — the two brightest things in the sky. Then it feeds you vocabulary that uses it: 明るい (akarui, bright), 説明 (setsumei, explanation).

Reviews come back on a schedule. Get an item right and the next review is pushed further out; get it wrong and it comes back sooner. You must type the reading in kana, so passive “yeah I know that one” recognition doesn’t count. There are 60 levels, covering roughly 2,000 kanji and several thousand vocabulary words. Most people who finish take somewhere between one and a few years, depending on how consistently they do reviews — the honest answer is that the pace is set by how often you show up, not by the app.

What’s genuinely great: you never plan. The mnemonics are good. The radical-first order means kanji stop looking like noise and start looking like assembled parts.

What frustrates people: you can’t skip kanji you already know without doing the levels (there’s no full test-out), the pace is capped early on, and the vocabulary is chosen to reinforce kanji rather than to be the most useful words for daily life. It’s also a subscription, with monthly, annual and lifetime options.

How Anki actually works

Anki is a blank SRS. You give it cards; it schedules them. That’s the whole product, and that’s why it’s so powerful and so easy to abuse.

Three ways people use Anki for kanji:

1. Download a shared deck. The widely used Core 2k/6k vocabulary decks and the newer Kaishi 1.5k beginner deck get you studying in ten minutes with audio and example sentences.
2. Mine your own sentences. You read or watch something, hit a word you don’t know, and make a card from the real sentence you met it in. This is slower to set up and dramatically more memorable.
3. Both. A shared deck for the first thousand words, mining after that.

Anki’s scheduler (the modern FSRS algorithm) is measurably good at predicting when you’re about to forget something, and you can tune how much you’re willing to forget. Add-ons handle everything from automatic audio to statistics you’ll never need.

What’s genuinely great: it’s free on desktop and Android, it studies exactly what you decide is worth studying, and the skill transfers — you can use the same app for JLPT grammar, medical school, or anything else.

What frustrates people: Anki has no opinion. It will happily let you build a terrible deck, drown in 400 reviews a day, and quit. Card design is a real skill, and most people’s first deck is bad. The iOS app costs money — that revenue funds development of the free versions.

Which one fits you?

Be honest about which of these sentences is true about you.

Take WaniKani if: you’re early, you get paralysed by choices, you want mnemonics handed to you, you’ll do reviews on a phone during a commute, and you’d rather pay money than spend hours configuring software.

Take Anki if: you already know some kanji and refuse to re-learn them, you’re studying for a specific exam or a specific book, you want to mine words from things you actually read, you’re on a budget, or you enjoy tinkering.

Take neither, yet, if you haven’t finished hiragana and katakana. Kanji before kana is building the roof before the walls.

If you’re not sure where you’re starting from, test your JLPT level first — knowing whether you’re at N5 or N3 changes the answer completely. An N5 beginner benefits enormously from WaniKani’s rails. An N3 learner usually has too much existing knowledge to sit through 60 levels from scratch.

The combination most serious learners land on

Here’s the setup I see work again and again, and the one I’d suggest if you can afford it:

• WaniKani for kanji recognition and readings. Let it own that job entirely. Don’t second-guess it, don’t add a competing kanji deck.
• Anki for everything WaniKani doesn’t do: vocabulary you meet in the wild, grammar points, sentences from your textbook.

The rule that keeps this sane: one SRS per job. The fastest way to quit Japanese is to have two apps testing you on 明るい on the same morning. WaniKani teaches you the character; Anki holds the words and sentences you personally encountered.

If you’re going Anki-only, use this order:

1. Finish kana.
2. Start a beginner vocabulary deck (Kaishi 1.5k or Core 2k) — vocabulary in context, not isolated kanji.
3. Add a kanji recognition deck only if you find you’re guessing words from sound alone.
4. Once you can read simple material, switch from downloaded decks to sentence mining.

Five rules that matter more than the tool

The SRS argument is mostly noise compared to these:

So: WaniKani or Anki?

If you’re a beginner who wants to open an app and be told what to do — WaniKani, no hesitation. Do the three free levels this week and you’ll know within days whether the mnemonics land for you.

If you’re further along, budget-conscious, or you already know a few hundred kanji — Anki, with a good beginner deck, and start mining sentences the moment you can read a paragraph.

And if you finish this post and open neither of them, the tool was never the problem. Pick one today, do the reviews tomorrow, and check back in ninety days. That’s the whole method.
