Duolingo Japanese: What It Teaches Well, and What It Quietly Skips

What Duolingo Japanese actually is in 2026

Duolingo Japanese is one vertical path of short lessons, grouped into units, grouped into sections. If a review you are reading describes a tree of skill bubbles you can jump around inside, it is describing an app that stopped existing in 2022, when Duolingo replaced the tree with the path and fixed the order for everybody.

The course is built against the CEFR, the European proficiency scale, rather than the JLPT, the exam most Japanese learners actually care about. In April 2026 Duolingo announced that nine courses including Japanese now teach through B2, which it maps to a Duolingo Score of 129. Before that, learners could only finish content up to A2, a Duolingo Score of 59.

That is a real expansion and it deserves a caveat. B2 here is Duolingo's claim on Duolingo's own scale, measured against content Duolingo wrote. It is not a JLPT result, and no public JLPT mapping exists for the course, so your progress bar cannot tell you whether you are ready for N5 or N3. A CEFR level in Japanese also costs an English speaker far more hours than the same level in Spanish, which the scale itself never mentions.

Here is what sits inside the current course:

So the honest shape of it: a long, ordered, free course that goes further than it did two years ago, with the writing systems handled in a side compartment. That side compartment is where a Japanese review has to spend most of its time.

How Duolingo teaches hiragana and katakana

Properly, and this is the part critics get wrong. The course has dedicated character tabs, described by Duolingo as a writing system feature at the bottom of your home screen holding three tabs of interactive charts: hiragana, katakana and kanji.

Open a kana tab and you get the chart plus lessons attached to it, with tracing, matching, spelling and reading exercises. Tracing matters more than it sounds. Drawing さ (sa), き (ki) and ち (chi) in the right stroke order is what separates recognising them on a screen from reading them on a menu at speed.

The sequence is sensible too. Hiragana comes first, which is correct, because hiragana carries the particles and verb endings that hold sentences together. Katakana is folded into lessons early in Section 1, and kanji only start appearing later in Section 1, once you have a grip on both kana. Any decent textbook does the same thing in the same order.

The genuine flaw is placement. The tabs sit beside the path rather than inside it, and Duolingo's own phrasing gives the game away: head over to the tab once you feel ready. Nothing stops you ignoring them for months while the main path keeps feeding you sentences. A learner who never opens the tabs can build a 200 day streak and still not read a train sign.

One practical note. The character tabs launched on iOS and Android with the website following later, so check what your device actually shows before you plan your week around them.

If you want the charts themselves, ours are free and follow the same order: the hiragana chart with all 46 characters and their example words, then the katakana chart. If you are not sure why Japanese needs both, hiragana vs katakana settles it in one page.

Does Duolingo teach kanji?

Yes. Duolingo teaches kanji, and reviews claiming otherwise are years out of date. What matters is how.

The mechanic is stated plainly by Duolingo: when you meet a new kanji as part of a new word in the course, that character becomes available for practice in the kanji tab. From there you get lessons on its shape, its use in words with their different pronunciations and meanings, tracing and freehand writing, and puzzle exercises. Tap a character and you see the words you have already learned that contain it.

Read that mechanic twice, because it decides everything else. Kanji arrive in the order the sentences need them. Not by stroke count, not by Japanese school grade, not by JLPT level, and not by building complicated characters out of simple parts the way a dedicated kanji app does. A word like 日本 (Nihon, Japan) turns up early because beginner sentences need it, not because its two kanji are the structurally obvious next step.

For plenty of characters that is fine. Where it costs you is readings. One kanji carries several, and which one you use depends on the word it is sitting in:

A kanji course teaches that as a pattern with rules and exceptions. Duolingo hands you the words and lets the pattern emerge on its own, which works if you meet hundreds of them and stalls if you meet forty.

The second gap is bookkeeping. Duolingo publishes no kanji count for the Japanese course and no JLPT mapping, so you cannot answer the question every kanji learner asks: how many do I know, and how many are left? Third-party reviews quote figures that contradict each other, which is usually a sign nobody has an official number.

The fair verdict on kanji, then: real teaching, real practice, no syllabus.

The romaji question: can you skate past the script?

Yes, you can, and the default setting makes it easy. Duolingo says so itself: from the very start you see hiragana and katakana in all your Japanese exercises, and you see romaji as well. Its own advice is to turn off romaji for an extra challenge once you feel more comfortable.

Read that as a product decision. The training wheels are on by default and taking them off is opt-in, which means most people never take them off. Duolingo made a deliberate trade there: fewer learners quit in week one, more learners coast for a year.

The cost is specific, because romaji quietly solves the two things kana is trying to teach you.

It hides the particle rule. わたしはがくせいです (watashi wa gakusei desu) means 'I'm a student'. That は is written ha and read wa, because it is doing grammar rather than spelling a word. Romaji prints wa for you, so the rule never has to enter your head. The same goes for へ read e, and を read o. Our hiragana chart covers all three particle readings.

It also hides length. おばさん (obasan) means aunt. おばあさん (obāsan) means grandmother. In kana that extra あ is a visible, countable beat sitting there on the page. In romaji it is a small bar over a vowel that your eye slides straight past.

The fix takes a minute. Go into your Japanese course settings, switch romaji off, ideally around week two, and accept that the next three sessions will feel slow. The menu has moved between app versions, so check both the in-lesson settings and your course settings if it is not where you expect. If your reading falls apart without romaji, that is not a setback. That is the real state of your reading, finally visible.

Where Duolingo Japanese is genuinely strong

Start with the free tier, because it is not a demo. You can work through the whole path without paying. Free sessions are paced by a resource: Duolingo has been moving free learners from Hearts to Energy, a battery that lessons spend and correct answers top up, refilling in roughly a day, with a rewarded ad or gems available if you run dry. Which system you personally see depends on your account, since the switch rolled out gradually.

Then the streak, which deserves more credit than language snobs give it. Japanese takes years, and the usual failure mode is not confusion, it is stopping. Duolingo is the best product ever built for getting a person to open a language app on a Tuesday when they do not feel like it. Anyone rolling their eyes at gamification should count how many serious learners quit in month four.

Kana drilling is the third win. The character tabs alone justify installing the app, even if you intend to learn everything else somewhere else entirely.

There is also no setup cost, which matters more for Japanese than for any European language. No textbook to buy, no Japanese input method to install, no decision about where on earth to start. You tap tiles. For a script this intimidating, removing every excuse in week one is worth more than it looks on paper.

And you see thousands of correct sentences. Japanese puts the verb last, marks roles with particles instead of word order, and drops subjects constantly. Reading a few thousand well-formed sentences builds a feel for that shape before anyone explains it, which is exactly what a beginner should be doing.

Finally, Explain My Answer closed the oldest complaint against the course. The classic charge was that you got marked wrong and told nothing. Since 1 January 2026 that per-mistake explanation is free for every learner, Japanese included. It is a genuine improvement, and the next section is about what it still does not do.

Where Duolingo Japanese falls short

Every gap below is specific to Japanese. A Spanish learner would barely notice most of them.

Grammar is met, not taught

Japanese grammar is largely particles and verb endings, and both need explaining out loud. は marks the topic, が marks the subject, and the difference between them is the most asked question in beginner Japanese. Exposure alone does not settle it, because both sentences look correct and the distinction lives in what the speaker is doing rather than in the words on screen.

Politeness has the same shape of problem. 食べる (taberu) and 食べます (tabemasu) both mean 'eat', and choosing the wrong one at work is a social mistake rather than a grammatical one. A course that teaches by pattern will show you both and leave you unsure which register you just produced. Explain My Answer helps after you slip. It is feedback, not a syllabus, and you cannot read it in advance.

Listening is clean and slow

Course audio is one speaker, one sentence, studio-clear, on a topic you were primed for two seconds earlier. Real Japanese is fast, contracted, missing its subjects, and frequently two people at once. DuoRadio is a real improvement and it is still learner-paced. Nothing in the app prepares you for a station announcement.

You assemble sentences more than you produce them

This is the deepest gap, and Duolingo has said the quiet part itself: answering from a word bank and answering from a keyboard demand very different levels of active recall. Tapping the right tiles out of a set of eight is recognition wearing production's clothes.

The keyboard toggle does exist, in every course from level 2 upward. For Japanese it means installing a Japanese input method and typing romaji that converts to kana and then to kanji, a real skill and a real barrier, and most learners never switch. Speaking to an actual person means Video Call, and Video Call is a Duolingo Max feature, so the free tier tops out at repeat-after-me.

Kanji has no syllabus

Covered above, and worth listing here as a gap: real practice, vocabulary-driven order, no published count, no map to the exam you might be sitting.

What to pair with Duolingo Japanese, and who should skip it

The course covers roughly half of what a beginner needs. Fill the other half with three things, in this order.

Kanji, with spaced repetition. A dedicated kanji tool orders characters deliberately and schedules reviews around what you personally keep forgetting. Anki with a shared deck is free and ugly. WaniKani is paid and does the ordering for you. Either one beats absorbing kanji by accident.

Grammar, from something that explains. Tae Kim's Guide to Japanese Grammar is free online and starts from how Japanese actually works instead of from English translations. Genki is the standard classroom textbook if you prefer paper and exercises. Read one particle chapter and a hundred Duolingo sentences stop being mysterious.

Input at real speed, earlier than feels comfortable. Learner-aimed Japanese video and podcasts first, then anything made for Japanese people. You need hours rather than lessons, and the only requirement is that you roughly follow along.

Add a tutor when your budget allows. Thirty minutes a week with a person who reacts does something no app does, because retrieving Japanese under mild social pressure is the exact skill the app is not training.

Who Duolingo Japanese is for

Absolute beginners who have never seen kana. Anyone who has failed to build a study habit before and needs the streak. Travellers who want survival phrases and menu-reading inside six months. People testing whether they even enjoy Japanese before spending money on it.

Who should skip it

Anyone who already reads kana comfortably and wants kanji volume, who should go straight to an SRS deck. Anyone with a JLPT date, since the course does not map to the exam. Anyone who needs to speak within months, because the app's speaking practice is either scripted or behind the paid tier. And anyone who already knows that streaks make them anxious rather than consistent.

Still choosing? Our best app to learn Japanese comparison puts Duolingo next to the alternatives, and the free Japanese lessons here start exactly where the app's character tabs do.
