Best Free Japanese Learning Apps in 2026: 10 Apps Ranked

Why Free Apps Deserve a Serious Look in 2026

The Japanese learning app landscape has changed dramatically over the past few years. Tools that once required expensive subscriptions now offer generous free tiers, and entirely free resources have matured to the point where they rival paid alternatives in content quality. The idea that you need to spend $10 to $20 per month to access quality Japanese learning tools is simply no longer true. Some of the most effective study tools available today cost absolutely nothing.

That said, not all free apps are created equal. Some free apps pad their listings with shallow content, lock essential features behind paywalls after a brief trial, or use outdated learning methodologies that waste your study time. The difference between a well-designed free app and a poorly designed one can mean the difference between passing the JLPT in six months and still struggling with basic vocabulary after a year. We have seen this pattern play out hundreds of times in the Japanese learning community.

That is why we wrote this guide. We spent four weeks testing every free Japanese learning app we could find — over 30 in total — and narrowed the field down to the 10 that actually deliver value. Our criteria were simple: does the app teach useful Japanese? Does it use effective learning methods? Is the free version genuinely usable, not just a demo? And critically, does it help you progress toward concrete goals like passing the JLPT? If you are preparing for a specific exam level, our JLPT N5 vocabulary page shows you exactly what words you need to know.

How We Tested These Free Apps

Every app on this list was tested for at least two weeks of daily use. We evaluated each one on five dimensions: content quality (is the vocabulary accurate, well-organized, and relevant to JLPT levels?), learning methodology (does it use spaced repetition or another evidence-based approach?), free tier generosity (can you actually learn meaningful amounts without paying?), usability (is the app pleasant to use every day, or does it create friction?), and JLPT alignment (does the content map to official JLPT vocabulary and kanji lists?). We weighted JLPT alignment and learning methodology most heavily because these factors have the greatest impact on actual exam outcomes. To understand why spaced repetition matters so much, see our deep dive on spaced repetition for Japanese.

Quick Comparison: All 10 Free Apps at a Glance

Now let us dive into each app in detail, starting with our top-ranked free option.

1. JLPTLord (Free Tier) — Best Free JLPT Vocabulary Tool

What it is: JLPTLord is a web-based vocabulary learning platform designed exclusively for JLPT preparation. The free tier provides access to JLPT-aligned vocabulary across all five levels (N5 through N1) with a built-in spaced repetition system. Every word is presented with kanji, furigana (hiragana reading), romaji, and English translation — for example, 食べる (たべる / taberu) means “to eat.” This multi-format display helps beginners who are still learning to read kanji while maintaining exposure to the characters.

Why it ranks first: JLPTLord earns the top spot because no other free tool combines JLPT-specific vocabulary curation with genuine spaced repetition this effectively. The word lists are organized by exact JLPT level, so you never waste time studying vocabulary that is too easy or too advanced for your target exam. The progress dashboard shows how many words you have mastered at each level and estimates your exam readiness. While the free tier has limitations compared to the paid plan, it offers enough vocabulary and review sessions to build a genuine foundation at any JLPT level. Most importantly, it works immediately — you can sign up and start studying real JLPT vocabulary in under a minute with zero configuration.

Honest limitations: The free tier does limit the number of new words you can learn per day and does not include all premium features like detailed analytics and unlimited review sessions. For serious JLPT preparation at N2 and N1, you will likely want to upgrade to the paid plan eventually. But as a free starting point for JLPT vocabulary, nothing else comes close. For a detailed comparison with another popular option, see our JLPTLord vs Anki comparison.

2. Anki — Best Free Customizable Flashcard System

What it is: Anki is an open-source spaced repetition flashcard app that is completely free on desktop (Windows, Mac, Linux) and Android. It is the Swiss Army knife of language learning tools — infinitely customizable, with a massive library of shared decks created by the community. For Japanese learners, popular shared decks include Core 2000/6000 (common Japanese words with audio), JLPT-specific vocabulary decks for each level, and sentence mining decks built from novels and manga.

Why it ranks second: Anki's spaced repetition algorithm (based on SM-2 with community modifications) is genuinely world-class. When configured properly, it schedules reviews at optimal intervals for long-term retention. The shared deck ecosystem means you can find high-quality JLPT vocabulary decks for free, complete with audio recordings, example sentences, and kanji breakdowns. Advanced users can create cards from their own immersion material, add images and audio, and build a truly personalized study system. Anki is also the only tool on this list that gives you complete ownership of your data — your decks are stored locally and can be exported anytime.

Honest limitations: Anki's biggest weakness is its learning curve. The interface is utilitarian at best and confusing at worst. New users routinely spend hours figuring out how to import decks, adjust card formatting, and configure review intervals. The default SRS settings are not optimized for Japanese vocabulary, and finding the right shared deck among thousands of options requires research. The iOS app costs $25, which makes Anki not truly free for iPhone users. If you value your time and want to start studying immediately, JLPTLord's zero-configuration approach is more efficient. But if you enjoy tinkering with systems and want maximum flexibility, Anki is unbeatable.

3. Duolingo Japanese — Best Free App for Motivation

What it is: Duolingo is the world's most popular language learning app, and its Japanese course has improved substantially over the years. It teaches hiragana, katakana, basic kanji, vocabulary, and sentence construction through short interactive lessons. The free version includes all content but is supported by ads and limits your daily “hearts” (attempts before you need to wait or pay).

Why it ranks third: Duolingo excels at one thing: getting you to study every day. Its gamification — streaks, leaderboards, experience points, and achievement badges — is incredibly effective at building a daily habit. For absolute beginners who have never studied Japanese, Duolingo provides the gentlest on-ramp available. It teaches hiragana and katakana through gradual exposure, introduces kanji slowly, and builds basic sentence patterns through translation exercises. The audio quality is good, and the listening exercises provide genuine ear training. For a deeper comparison, see our JLPTLord vs Duolingo Japanese analysis.

Honest limitations: Duolingo's vocabulary does not align with JLPT word lists. You will learn words that never appear on the exam while missing critical vocabulary that does. The review system is not true spaced repetition — it uses a simpler algorithm that prioritizes engagement over optimal learning intervals. Content depth drops off sharply after approximately N4 equivalent material. If your goal is passing the JLPT, Duolingo should be a supplement, not your primary tool. It is excellent for building a study habit during your first month, but you will need to transition to JLPT-aligned tools like JLPTLord for serious exam preparation.

4. Tae Kim's Guide to Japanese Grammar — Best Free Grammar Reference

What it is: Tae Kim's Guide to Learning Japanese is a comprehensive, completely free grammar reference that covers everything from absolute basics (what are particles?) to advanced grammar patterns used in N2 and N1 material. It is available as a website, and community-created apps exist for both iOS and Android. The guide takes a systematic approach, building grammar concepts logically from simple to complex with abundant example sentences in Japanese with English translations.

Why it ranks fourth: No free resource explains Japanese grammar as clearly and comprehensively as Tae Kim. The guide covers particles (は, が, を, に, で, and dozens more), verb conjugation (te-form, potential form, passive, causative), sentence structures, honorific language, and advanced literary patterns. Each concept is explained in plain English with multiple example sentences that demonstrate real usage. Unlike textbooks that cost $30 to $50, Tae Kim is entirely free and accessible from any device. It is the go-to grammar reference recommended by nearly every Japanese learning community online, and for good reason — the explanations are accurate, the examples are natural, and the progression is logical.

Honest limitations: Tae Kim is a reference guide, not a practice tool. It explains grammar concepts excellently but does not provide exercises, quizzes, or spaced repetition to help you internalize what you read. You need to actively practice grammar points through writing, speaking, or using a separate grammar SRS tool. The guide also has not been significantly updated in several years, so it does not cover the most recent trends in Japanese language teaching methodology. Pair it with a vocabulary tool like JLPTLord and you have the grammar and vocabulary pillars covered for free.

5. NHK World Easy Japanese — Best Free Listening Practice

What it is: NHK World Easy Japanese is a free service from Japan's national broadcaster that provides simplified news articles written in easy-to-read Japanese with furigana above all kanji. Articles are updated daily, covering current events in Japan and around the world. Many articles include audio read at a slower pace, making them ideal for listening practice. NHK also offers structured Japanese lessons through their “Easy Japanese” learning program with audio dialogues and explanations.

Why it ranks fifth: Listening comprehension is the hardest skill to develop for free because quality audio content is expensive to produce. NHK fills this gap exceptionally well. The news articles provide authentic, culturally relevant content that keeps you engaged — you are learning about real events in Japan, not artificial textbook dialogues. The furigana support means you can read along while listening, building the crucial skill of matching spoken Japanese to written forms. New content appears daily, so you never run out of fresh material. For learners preparing for the listening section of the JLPT, NHK World is an invaluable free resource that simulates the kind of comprehension required on the exam.

Honest limitations: NHK World Easy Japanese is primarily a reading and listening resource, not a structured learning app. It does not teach vocabulary systematically, does not use spaced repetition, and does not track your progress. The “easy” articles are roughly N3 to N4 level, which means complete beginners will struggle. You need a separate vocabulary tool (like JLPTLord) to learn the words you encounter in NHK articles, and a grammar reference (like Tae Kim) to understand the sentence patterns.

6. Jisho.org — Best Free Japanese Dictionary

What it is: Jisho.org is a free online Japanese-English dictionary that has become the standard reference tool for Japanese learners worldwide. It supports searching by English, romaji, hiragana, katakana, or kanji. Results include readings, meanings, example sentences, kanji stroke order diagrams, JLPT level tags, and links to related words. It also supports radical-based kanji lookup and sentence parsing, where you can paste an entire Japanese sentence and get a word-by-word breakdown.

Why it ranks sixth: Jisho is not a learning app in the traditional sense — it does not use flashcards or spaced repetition. But it is arguably the most essential free tool for any Japanese learner. Every time you encounter an unknown word while reading manga, watching anime, or studying with another app, Jisho is where you look it up. The JLPT level tags are particularly valuable: when you search for a word, Jisho tells you which JLPT level it belongs to, helping you decide whether it is worth memorizing now or later. The sentence parser is incredibly useful for breaking down complex sentences you encounter in the wild. Jisho is the tool that ties your entire study ecosystem together.

Honest limitations: As a dictionary, Jisho does not teach you anything proactively. It is a passive reference tool that requires you to come to it with a question. The example sentences are sourced from the Tatoeba project, and quality varies — some are natural, others are awkward translations. There is no mobile app (though the website works well on mobile browsers), and there is no offline mode. For structured vocabulary learning, you still need a dedicated tool like JLPTLord or Anki.

7. Takoboto — Best Free Android Dictionary

What it is: Takoboto is a free Japanese-English dictionary app for Android that works entirely offline after the initial download. It features a comprehensive word database, example sentences for most entries, conjugation tables for verbs and adjectives, JLPT level tags, and a built-in flashcard feature for saving and reviewing words you want to memorize. The interface is clean and search is fast, even on older devices.

Why it ranks seventh: For Android users, Takoboto is the best free dictionary app available. Its offline capability means you can look up words on the train, in class, or anywhere without an internet connection. The example sentences are a standout feature — seeing a word used in context dramatically improves comprehension compared to reading a bare definition. The built-in flashcard feature, while basic, lets you save words as you encounter them and review them later with a simple quiz interface. JLPT level tags on every entry help you prioritize which words to study. If you are an Android user studying Japanese, Takoboto should be on your home screen.

Honest limitations: Takoboto is Android-only, so iOS users need to look elsewhere (see Shirabe Jisho below). The built-in flashcard system is basic and does not use true spaced repetition — it is more of a simple quiz that cycles through your saved words. For systematic vocabulary learning, you still need a dedicated SRS tool. The app also does not include kanji stroke order diagrams, which limits its usefulness for kanji writing practice.

8. Kanji Study — Best Free Kanji Practice App

What it is: Kanji Study is an Android app that focuses specifically on kanji learning. The free tier includes comprehensive kanji data for all JLPT levels, animated stroke order diagrams, readings (both on'yomi and kun'yomi), meanings, and example vocabulary for each character. The app supports multiple study modes including flashcards, writing practice (where you draw the kanji on screen and it checks your stroke order), and quizzes. Kanji are organized by JLPT level, making it easy to study only the characters relevant to your target exam.

Why it ranks eighth: If your weak point is kanji, this is the best free tool for focused kanji practice. The stroke order animations are beautifully rendered and the writing practice mode gives you genuine feedback on whether your strokes are correct and in the right order. Learning proper stroke order is not just about aesthetics — it helps with kanji recognition and memory because the motor memory of writing reinforces visual recognition. The JLPT organization means you can work through exactly the kanji you need for your next exam. For learners who want to understand how kanji fits into vocabulary study, our best JLPT apps guide covers the broader tool ecosystem.

Honest limitations: The free tier limits access to some advanced features and study sets. Kanji Study is Android-only, leaving iOS users without this specific tool. Most importantly, studying kanji in isolation (individual characters without vocabulary context) is less efficient than learning kanji as part of words. A character like 食 is more memorable when you learn it through words like 食べる (たべる / taberu — to eat) and 食事 (しょくじ / shokuji — meal) than when you study it as an isolated character with a list of readings. Tools like JLPTLord that teach kanji through vocabulary provide better retention for most learners.

9. Shirabe Jisho — Best Free iOS Dictionary

What it is: Shirabe Jisho is a free Japanese-English dictionary for iOS that provides offline access to a comprehensive word database. It features a clean, native iOS interface with support for searching by English, romaji, kana, or kanji. Results include readings, definitions, example sentences, JLPT level tags, kanji details with stroke order, and related words. The app integrates well with iOS features like Spotlight search and the share sheet, making it easy to look up words from any other app.

Why it ranks ninth: For iOS users, Shirabe Jisho is the equivalent of what Takoboto is for Android — the best free native dictionary app on the platform. Its offline capability, clean interface, and comprehensive data make it an essential tool for daily study. The iOS integration is particularly valuable: you can select text in Safari, a messaging app, or any other application and share it directly to Shirabe Jisho for instant lookup. JLPT level tags help you identify which words are worth adding to your study queue. The kanji details page shows readings, meanings, stroke order, and all vocabulary words that use that character, making it a useful kanji reference as well.

Honest limitations: Like all dictionary apps, Shirabe Jisho is a passive reference tool, not an active learning system. It does not include flashcards, spaced repetition, or any form of structured study. The example sentence quality is variable. For structured learning, pair it with JLPTLord (accessible via mobile browser) and use Shirabe Jisho as your quick-lookup companion for words you encounter throughout the day.

10. HiNative — Best Free Community Q&A for Japanese

What it is: HiNative is a free language exchange platform where you can ask questions about Japanese and get answers from native speakers. The free tier lets you ask questions using structured templates (like “How do you say this in Japanese?” or “Does this sentence sound natural?”) and browse other users' questions and answers. The community is active, and most questions receive responses within minutes. You can also help others learn your native language in return, which creates a reciprocal learning ecosystem.

Why it ranks tenth: HiNative fills a gap that no other free tool on this list covers: getting real-time answers from native Japanese speakers about nuance, naturalness, and cultural context. When you are unsure whether a sentence sounds natural, when you want to know the difference between two similar words, or when you need to understand a cultural reference, HiNative provides answers that no dictionary or app can. The structured question templates make it easy to ask clearly even if your Japanese is basic. It is an invaluable supplement to your core study tools.

Honest limitations: HiNative is not a learning app — it does not teach vocabulary, grammar, or kanji. Answer quality depends on individual community members and is not professionally reviewed, so occasionally you will receive conflicting or incorrect answers. The free tier limits the number of questions you can ask per day and shows ads. Premium features like audio answers and priority support require a subscription. Use HiNative as a supplement for specific questions, not as a primary study tool.

Our Verdict: Which Free Apps Should You Use?

The best combination of free apps depends on your specific goal. Here are our recommendations by learner type.

If you are preparing for the JLPT (any level): Start with JLPTLord free tier for JLPT-aligned vocabulary with spaced repetition. Add Tae Kim for grammar study. Use NHK World Easy Japanese for listening practice once you reach N4 level. Keep Jisho.org (or Takoboto/Shirabe Jisho on mobile) open for dictionary lookups. This four-tool stack covers vocabulary, grammar, listening, and reference at zero cost. When you need more vocabulary depth, consider upgrading to JLPTLord's paid plan or adding Anki with a JLPT deck. Check our pricing page to see what the paid plan adds.

If you are a casual learner who wants to explore Japanese: Start with Duolingo for the first month to build a study habit and learn hiragana and katakana. Then transition to JLPTLord free tier for more efficient vocabulary study and Tae Kim for grammar. Duolingo is excellent at getting you started, but you will outgrow it quickly if you are serious about learning. The transition from Duolingo to purpose-built tools is the single most impactful change a casual learner can make.

If you are a power user who wants maximum control: Build your system around Anki with a high-quality shared deck (Core 6000 or a JLPT-specific deck). Pair it with Tae Kim for grammar, NHK World for listening, and Jisho for reference. Invest time upfront to configure Anki's settings properly — optimize the SRS intervals, set up card templates with kanji, furigana, and audio, and organize decks by JLPT level. This approach requires the most setup time but gives you the most flexibility. Many power users eventually try JLPTLord and appreciate not having to maintain their own system.

If kanji is your main challenge: Use Kanji Study (Android) for dedicated stroke order and writing practice, then reinforce kanji recognition through vocabulary study on JLPTLord. Learning kanji in the context of real words (食べる rather than just 食) produces better retention and is more directly useful for reading and the JLPT. Our comprehensive app comparison covers paid kanji tools like WaniKani if you are willing to invest in dedicated kanji study.

Whatever combination you choose, remember this: consistency matters far more than the specific tool. Thirty minutes every day with a good free app will produce dramatically better results than sporadic sessions with the best paid app. The tools on this list are all genuinely useful — the limiting factor is almost always study consistency, not tool quality. Pick your stack today, commit to daily practice, and start building toward your Japanese language goals. If you want a complete study plan built around these tools, our JLPT N5 study materials provide a structured starting point for beginners.
