Duolingo Japanese Review: Does It Actually Work in 2025?
Last updated: December 26, 2025
It's all natural to go for Duolingo to learn Japanese when you don't know where to start. Makes sense, the app is free, popular, and everyone seems to be using it for something. But here's what you actually need to know: Duolingo can get you started with Japanese basics, but if you're serious about reaching any meaningful level, you'll hit a wall pretty quickly.
I've spent time with the Duolingo Japanese course, and I'm going to break down exactly what works, what doesn't, and whether it's worth your time. No sugarcoating here.

- What Duolingo Japanese gets right for beginners
- Where Duolingo falls short for Japanese learners
- Are there any reasons to use Duolingo for studying Japanese?

What Duolingo actually teaches you in its Japanese lessons
The Duolingo Japanese course features a separate chart of hiragana (ひらがな) and katakana (カタカナ). This is actually a solid approach because you need hiragana to read basically anything in Japanese and katakana for foreign words.
The course includes around 2,000 words and covers basic grammar patterns. You'll learn sentence structures like meaning "I am a student" and simple verb conjugations. Duolingo claims the course can take you to around JLPT N5 or N4 level, which is beginner to upper beginner.
The level of Japanese to reach with Duolingo
Realistically, if you complete the entire Duolingo Japanese course, you'll be somewhere around JLPT N5 level, maybe touching N4. That's absolute beginner.
To put this in perspective, JLPT has five levels, with N5 being the easiest and N1 being the hardest. N5 means you can understand basic phrases, introduce yourself, and read simple sentences with hiragana and basic kanji. N4 adds more vocabulary and slightly more complex grammar.
Neither of these levels means you can have a real conversation, watch Japanese media without subtitles, or read a book. You're still firmly in "tourist phrase book" territory.
The Duolingo course teaches you maybe 2,000 words. Fluent Japanese speakers know 10,000+ words. You can see the gap.
What Duolingo Japanese gets right for beginners
Let's be fair. Duolingo does some things well, especially if you're a complete beginner who knows absolutely nothing about Japanese.
The gamification actually works. The streaks, points, and levels genuinely motivate people to open the app daily. For language learning, consistency matters more than intensity, so if Duolingo gets you to study 10 minutes every day instead of zero minutes, that's valuable. The dopamine hit and the app plug on the phone screen keep people coming back.
It's completely free. You can access the entire Japanese course without paying anything. Sure, there are ads, and the Super Duolingo premium version exists, but the core content is available to everyone. For someone who wants to dip their toes into Japanese without financial commitment, this is huge.
Zero pressure environment. You can make mistakes privately, repeat lessons endlessly, and learn at your own pace. For shy learners or people with language learning anxiety, this feels safer than a classroom.
Where Duolingo falls short for Japanese learners
Now for the problems, and there are many.
Grammar explanations are basically nonexistent. Duolingo expects you to figure out grammar patterns through exposure and repetition. This might work for languages similar to English, but Japanese grammar is fundamentally different. The app will throw you a sentence like meaning "this is my book" without explaining the particle "wa" (は) or why "no" (の) indicates possession. You're left guessing at rules you should understand clearly.
Kanji learning is terrible. Japanese uses around 2,000 kanji for everyday literacy. Duolingo introduces kanji randomly without teaching you how they're constructed, what the radicals mean, or how to write them. You might see meaning "expensive" or "tall" without learning that the kanji 高 is built from component parts that help you remember it. This makes kanji feel like arbitrary symbols you have to memorize instead of a logical system you can learn efficiently.
The sentences are often unnatural or useless. Duolingo is somewhat famous for this across all languages. You'll spend time learning sentences like "I eat apple" when you'll probably never say that in this grammar setting.
No pitch accent instruction. Japanese is a pitch accent language, meaning the pitch pattern of a word changes its meaning. () with one pitch pattern means "chopsticks" while with a different pattern means "bridge." Duolingo follows the pitch when playing the audio, but the app does not mark the pitch out directly.
Are there any reasons to use Duolingo for studying Japanese?
Yes, a few specific situations where Duolingo makes sense:
- You want zero financial commitment. If you're genuinely unsure about learning Japanese and want to test the waters before spending money, Duolingo lets you do that. It's a free trial for the language itself.
- You need something extremely low-pressure. Maybe you have severe anxiety about language learning or bad experiences from school. Duolingo's private, game-like environment might help you get started when nothing else would.
- You have tiny pockets of dead time. Waiting for a bus, standing in line, commercial breaks. Duolingo works well for 3-5 minute sessions when you wouldn't be able to do more intensive study anyway. Better than scrolling social media.
But notice these are all pretty limited use cases. None of them is "I want to become conversational in Japanese" or "I want to pass the JLPT" or "I want to watch anime without subtitles." For those goals, Duolingo won't cut it.
Some better alternatives to Duolingo for Japanese language learning
Let's talk about what actually works better for serious Japanese learners.
- For structured courses: LingoDeer and Japademy both offer Japanese courses designed specifically for Asian languages. Unlike Duolingo, which tries to use the same framework for all languages, these apps understand that Japanese needs different teaching methods. They include better grammar explanations, writing practice, and more natural example sentences.
- For vocabulary and kanji: WaniKani uses spaced repetition and mnemonics to teach kanji and vocabulary in a logical order. It breaks down each kanji into radicals and gives you memorable stories to help retention. This is infinitely better than Duolingo's random kanji introduction. You could also use Anki with good pre-made decks for Japanese learners.
- For grammar: Bunpro is a platform dedicated entirely to Japanese grammar using spaced repetition. It covers everything from beginner to advanced and links to detailed grammar explanations. Pair this with a textbook like Genki and you'll actually understand how Japanese works.
- For listening and immersion: This is where you need real Japanese content. YouTube channels, podcasts, dramas, anime. Start with content for learners like Comprehensible Japanese or Japanese Ammo with Misa, then gradually move to native content. Your listening skills will improve 10x faster than with Duolingo's robot voices.
- For speaking: You need actual conversation practice. Apps like iTalki connect you with native Japanese tutors for affordable one-on-one lessons. Even 30 minutes a week of real conversation beats months of Duolingo's speaking exercises.
Combining Duolingo and other resources to learn effectively
Use Duolingo if you're a complete beginner who wants a free, low-pressure introduction to Japanese. Spend a week or two learning hiragana and katakana, get familiar with basic words, and see if you enjoy studying the language.
Then move on and use Duolingo together with other resources. Start to follow a real textbook, start using spaced repetition for vocabulary, find native content to immerse in, and practice with actual people. The key is not to stick with any particular resources, but to leverage and maximize their advantages.
Anyway, if you want to actually learn Japanese through immersion with real content, Migaku's browser extension and app let you look up words instantly while watching Japanese shows or reading articles. Makes immersion learning way more practical, especially once you're past the Duolingo beginner stage. There's a 10-day free trial if you want to check it out.
There's no perfect learning app, but you can make your choice count!
Every Japanese learning app has its pros and cons, and usually, these apps will have the areas they are targeting, be it for grammar, vocabulary, or immersion. That's why, as a smart learner, you should try out your options and strategize your move to integrate them into your daily study. Additionally, to make the journey more enjoyable, try adding media like dramas and movies to your study plan.
If you consume media in Japanese, and you understand at least some of the messages and sentences within that media, you will make progress. Period.
Tools are for you to use!
