The Best Apps for Learning Japanese in 2026

Every "best Japanese app" list ranks apps as if they were competing for the same job. They aren't. Learning Japanese has four distinct jobs (kana, vocabulary, grammar, and input), and every app on this list is strong at one or two of them and weak at the rest.

So here's what each app is actually for, ranked by which of those jobs it does best, and how to combine two or three into a setup that covers all four.

The best Japanese learning apps at a glance

An app that claims to do all four jobs usually does none of them well enough to be your main tool. The ordering below is by how completely each app owns its job, not by how good the app is overall.

The four jobs every Japanese learner has to cover

1. Kana: hiragana and katakana. A one-time, two-week job.
2. Vocabulary: the largest and most continuous job. Thousands of words, spaced out over years.
3. Grammar: a finite, structured job. Roughly a textbook's worth to get to N3.
4. Input: reading and listening to real Japanese. Never ends, and it's what turns study into ability.

1. Cotobara: best for JLPT vocabulary

What it is — a vocabulary SRS built around a curated, JLPT- and frequency-ordered corpus. It is the tool we build, so read this section with that in mind; the rest of the list is written the same way regardless.

Best for — vocabulary, which is the biggest of the four jobs and the one most setups under-serve.

How it works — every word arrives with level-appropriate example sentences, natural-sounding audio, and a recall-focused review engine, with no deck to source, no scheduling algorithm to tune, nothing to maintain. Words come back as both recognition and production cards. The settings that exist are about you (your starting level, a rare-word filter, furigana on or off), not about the SRS. It can import your WaniKani progress so you never review what you've already burned.

Price — the free plan keeps the full beginner course and reviews for up to 50 words a day; Premium is what adds new words, up to 100 a day, and unlocks word breakdowns, notes and bookmarks. Every new account starts with a 30-day trial.

Skip it if you want grammar in the same app. It deliberately doesn't teach grammar, so it has to be paired with one of the grammar tools below.

2. Anki: best for building your own system

What it is — a spaced-repetition engine, not a course. The most flexible tool on this list and the one that asks the most of you.

Best for — vocabulary, on your own terms.

How it works — you source or build a deck, tune the settings, and review. FSRS is built in and schedules well without configuration. Everything else, from card templates to what happens to a word you keep failing, is yours to decide. The community deck ecosystem is enormous and uneven.

Price — free on desktop and Android including sync; the iPhone app is a one-off purchase.

Skip it if you don't enjoy building your own system. It is a common quiet failure point: three evenings comparing decks, one import, and no daily habit. (Which deck?, or alternatives that skip the setup.)

3. WaniKani: best for kanji characters and readings

What it is — a kanji course that teaches radicals, then characters, then the vocabulary that illustrates them, via mnemonics and a fixed SRS.

Best for — kanji, and only kanji.

How it works — you unlock a level, learn its radicals and kanji, and the SRS decides when you see them again. You cannot rush it, which is the design working as intended rather than a flaw. Its job is narrower than people assume: it teaches characters and illustrative vocabulary, not general-purpose vocabulary and not grammar.

Price — the first three levels are free, then a subscription.

Skip it if you need general vocabulary. It is excellent at its job and will not do that one. (Is it enough for the JLPT?)

4. Bunpro: best for grammar SRS

What it is — a spaced-repetition system for grammar points, tracked by JLPT level.

Best for — grammar, the job most vocabulary tools leave open.

How it works — it drills grammar points in context with cloze-style questions and links out to explanations in the major textbooks and free guides. It assumes you are learning the grammar somewhere else and gives you the review layer on top.

Price — a trial, then a subscription.

Skip it if you have no grammar source to pair it with. Used alone it reviews explanations you haven't read yet. (Comparison.)

5. renshuu: best free all-in-one

What it is — a broad Japanese learning platform covering vocabulary, kanji, grammar and more, with a large and long-standing community.

Best for — covering several jobs in one place without paying.

How it works — schedules, quizzes and study lists across every category, extensively customisable, with a genuinely generous free tier. The breadth is the appeal and also the cost: there is more to configure and more to decide than in a single-job tool.

Price — free tier with a Pro subscription.

Skip it if you want one obvious next button. You will spend some time deciding what to use. (Comparison.)

6. Duolingo: best for building the daily habit

What it is — the gamified course almost everyone starts with.

Best for — the habit, and absolute-beginner exposure.

How it works — short lessons, streaks, leagues and notifications. The gamification is best in class and it is genuinely good at getting you to open an app daily, which is not a small thing given that consistency is what actually decides outcomes.

Price — free with ads; Super removes them.

Skip it if you are past absolute beginner. Its weaknesses are well documented: shallow grammar explanation, translation-heavy exercises, and sentences chosen for the exercise rather than for usefulness. Fine as a first two weeks or as a supplement; not a path to N3. (Longer comparison.)

7. LingoDeer: best structured beginner course

What it is — a course app built specifically for Japanese, Korean and Chinese rather than adapted from a European-language template.

Best for — grammar, for beginners who want a course rather than a reference.

How it works — it teaches grammar explicitly, in order, with explanation screens before the exercises. That ordering is the difference from Duolingo: you are told the rule and then practise it.

Price — a trial, then a subscription.

Skip it if you already own a textbook. It covers roughly the same ground as a first-year textbook, and doing both is duplicated work.

8. Satori Reader: best for graded reading

What it is — a library of original Japanese stories and articles with per-sentence audio, inline grammar notes, and difficulty you can adjust.

Best for — input, the job that turns study into ability.

How it works — you read at a level you can nearly handle, tap anything you don't know, and the notes explain the grammar rather than only glossing the word. You can set how much furigana appears and it tracks what you have marked as known.

Price — some free articles, then a subscription.

Skip it if you know fewer than a few hundred words. Graded reading needs a floor, and below it every sentence is a lookup.

9. jpdb: best for vocabulary from real media

What it is — a dictionary and SRS built around decks generated from actual anime, novels and games.

Best for — vocabulary, aimed at a specific thing you want to read or watch.

How it works — you pick the media you are about to consume, it builds a frequency-ordered deck of the vocabulary in it, and you pre-learn the words before you start. Its scheduler is its own. The interface is dense and assumes you know what you want.

Price — free.

Skip it if you want hand-holding. There is very little of it, deliberately.

10. NHK Easy News: best free input source

What it is — NHK's simplified news, with furigana on every kanji and audio on most articles.

Best for — input, at no cost.

How it works — real news, rewritten in simpler Japanese. New articles daily, so the habit has something to attach to.

Price — free.

Skip it if you need graded difficulty or grammar notes. It is simplified, not graded, and nothing explains anything to you. Once you have a few hundred words, this is where progress compounds, and it isn't optional or something a flashcard app substitutes for.

Sensible combinations

Absolute beginner, free: our kana course (free on every account) → the beginner grammar course, also free → then 30 days of Premium to build a deck, which stays yours to review for up to 50 words a day afterwards. Three tools, no cost, complete coverage.

Beginner who wants structure: Genki (grammar) + Cotobara (vocabulary) + NHK Easy once you pass ~600 words.

Kanji-focused: WaniKani (characters) + Cotobara (general vocabulary), plus a grammar resource. (Why they pair well.)

Tinkerer: Anki with a good deck + Bunpro + Yomitan for mining. Most control, most maintenance.

JLPT deadline: grammar resource for your level + vocabulary SRS daily + past papers. (Exam plan.)

How we chose these apps

Every app here is judged against one of the four jobs rather than against each other, because a kanji app and a grammar app are not substitutes and ranking them on a single scale produces a list that helps nobody choose.

Cotobara is our own product and it is first on the list, which is a conflict of interest and worth saying plainly rather than burying. The test we applied to it is the same one applied to everything else: does it own one of the four jobs completely enough to be the tool you use for that job. Where it doesn't (grammar, input) the list sends you elsewhere, and the combinations above are the setups we would actually recommend to someone starting this week.

Common questions

What's the best free app to learn Japanese?

For vocabulary, Anki if you are willing to configure it, or a free-tier SRS if you are not. For grammar, Tae Kim's guide. For input, NHK Easy News. Free covers three of the four jobs completely; it is the curation you pay for, not the capability.

Is Duolingo enough to pass the JLPT?

No, at any level. It does not cover the vocabulary volume or the grammar depth the exam tests, and it never claims to. It is useful for the habit and for the first few weeks of exposure.

Do I really need more than one app?

Usually two. One tool for vocabulary and one for grammar covers the jobs that a beginner can't skip, and reading fills in the fourth once you have the words for it. Three is the practical ceiling.

Which should I start with?

Kana first, for two weeks, from anywhere. Then a vocabulary SRS and a grammar resource, on the same day, both small. Starting vocabulary before kana means learning words you can't read.

The part that decides the outcome

The app matters much less than the sentence "did you open it today?" Every tool listed here works for someone; none work for someone who studies for two weeks and stops.

So choose on friction, not features. The best setup is the one where a bad day still produces fifteen minutes of study, which usually means fewer tools, less configuration, and a session you can finish on a phone while the kettle boils. Two apps you use daily beat six you rotate through and abandon.

If you want the shortest version: one grammar resource you finish, and Cotobara for the vocabulary every day. That covers three of the four jobs, costs nothing to start, and leaves only "read something real" to add once you have a few hundred words.
