Best app for learning Japanese in 2026: an honest comparison
There is no single best app for learning Japanese. The honest answer is that the best app depends on which phase of the Japanese language you are in. Grammar foundation, kanji study, vocabulary building, immersion reading, and conversation practice each have a different right answer, and most Japanese learners end up combining two or three apps in a stack.
The quick answer
As of May 2026, the best app for learning Japanese is not a single app. It is a small stack.
For grammar after Duolingo, use Renshuu (free) or Bunpro (around 5 USD per month). For kanji curriculum, use WaniKani (9 USD per month, 89 USD per year, or 300 USD lifetime). For popup dictionary lookup plus integrated spaced repetition while you read native Japanese text on the web, use immit (free). For deep-control flashcard review, use Anki (free on desktop). For conversation practice with native speakers, use italki or HelloTalk.
If we had to pick one Japanese learning app that closes the largest gap in the typical immersion stack, it would be immit, because lookup-plus-SRS in one tool is the place most learners lose hours to setup and context-switching. Try immit free on Chrome (no account required).
Quick comparison table
| App | Price (May 2026) | Best for | Free tier |
|---|---|---|---|
| immit | Free | Popup dictionary + integrated SRS during immersion reading | Yes, no account required |
| Renshuu | Free, Pro around 5 USD/mo | Post-Duolingo grammar + JLPT preparation | Yes, generous |
| Bunpro | Around 5 USD/mo or 40 USD/yr | Grammar SRS structured by JLPT level | 1-month trial |
| WaniKani | 9 USD/mo, 89 USD/yr, 300 USD lifetime | Structured kanji curriculum with mnemonics | First 3 levels free |
| Anki | Free desktop, paid iOS | Maximum-control SRS for self-built decks | Yes |
| Yomitan | Free, open source | Popup lookup if you enjoy configuring tools | Yes |
| Migaku | Around 9-19.99 USD/mo (verify) | Video subtitle workflow + Academy 1 course | 14-day refund only |
| Satori Reader | Around 9 USD/mo | Story-based graded reading with audio | Limited free articles |
| italki / HelloTalk | Tutor rates vary / free | Conversation practice with native Japanese speakers | HelloTalk free, italki pay-per-lesson |

How we picked these Japanese learning apps
We are writing this for intermediate and advanced learners who have already moved past hiragana and katakana, can read basic grammar, and now spend their study time on vocabulary building, reading native Japanese text, and grinding kanji. If you are an absolute beginner who just downloaded your first Japanese app, this list is not aimed at you. The right answer for week one is a different post.
There is also a learner-style split that matters more than features. Some Japanese learners enjoy configuration as part of the hobby and will happily set up Yomitan with five dictionaries, a custom Anki note type, and a sentence-mining workflow. Others want to learn Japanese, not learn a tooling stack. Both are valid. We have written this post for the second group. The first group already knows what to use.
One more frame: there is no magic single app that delivers Japanese fluency. Every advanced learner we know uses a combination. The question is which combination is worth the setup tax and which combination drops out of your routine after a week.
What makes the Japanese language hard, and what that means for app choice
Mastering Japanese requires three things that most other languages do not bundle together: a writing system with three scripts (hiragana, katakana, and roughly 2,000 kanji characters), complex grammar with verb conjugations and sentence patterns that do not map onto English, and pitch-accent pronunciation that is rarely taught in beginner Japanese courses. Each layer needs a different study mode, and that is why most apps cover one layer well and the others thinly.
Japanese writing breaks into three systems. Hiragana and katakana are phonetic alphabets used for grammar particles, native Japanese words, and loanwords. Kanji characters carry meaning and are used for most nouns and verb stems. Reading native Japanese text means switching between all three on every sentence. Basic practice with hiragana and katakana is non-negotiable in week one, but real reading literacy starts when kanji study gets serious.
Japanese language skills also split between recognition (read it, hear it, understand it) and production (speak it, write it). The apps in this list cover both sides, but most apps lean recognition-first. If you want to speak Japanese fluently, you will need conversation practice on top of any flashcard app. We cover that in the italki and HelloTalk section. Japanese is harder than most languages English-speaking language learners take on.
The last piece is cultural context. Japanese words often carry meaning that does not translate cleanly. A good Japanese app surfaces English translations alongside example sentences and cultural notes so you understand how words are used, not just what they map to. This is where context-rich tools like Satori Reader and the dictionary-side audit work in immit matter more than raw word counts.
The best app for learning Japanese, by phase
Phase 1: Grammar foundation (post-Duolingo)
Use Renshuu or Bunpro. Both teach grammar rules at your own pace with example sentences and structured lessons.
Phase 2: Kanji study
Use WaniKani for the structured curriculum, or Kanji Study if you want a free option with stroke order and radical search.
Phase 3: Vocabulary building through immersion
Use immit for popup lookup plus integrated SRS while you read Japanese text on the web. Anki if you want self-built decks and maximum control.
Phase 4: Listening practice and reading comprehension
Use Satori Reader for graded reading with audio. Use Netflix, YouTube, or manga with immit installed for unguided immersion.
Phase 5: Conversation practice
Use italki for paid lessons with professional teachers. Use HelloTalk for free language exchange with a language exchange partner.
The rest of this post goes app by app, in roughly the order you will need them.
1. immit
immit is a Japanese-specific popup dictionary with FSRS spaced repetition built in, available as a Chrome extension, with an optional desktop app for Mac, Windows, and Linux. Hover over any Japanese word on a web page, see the definition right there, save it in one click with the sentence it came from, and let immit schedule the review for you. No account is required and the lookup works offline.
Price (October 2026): Free, with no account required. Syncing across devices is free too with an optional account; there is no paid plan.
Strengths.
-
Popup lookup and SRS live in the same tool, so the workflow from discovery to review has zero context-switch.
-
The full lookup and SRS loop is free, with no account required. You can do real immersion-driven vocabulary building without paying.
-
Built by a duo (American intermediate learner, Japanese-native product designer) for their own use. Every dictionary entry has a report link, and reported problems are reviewed and corrected by a person.
-
Works offline, including the lookup.
Limitations.
-
No structured Japanese course or JLPT-tagged curriculum. immit assumes you are getting your grammar and kanji curriculum elsewhere.
-
No iOS or Android app. immit's lookup runs as a Chrome extension (with an optional desktop app for Mac, Windows, and Linux); reviews work on a phone through immit's web app, but lookup does not.
-
Works on YouTube captions (hover lookup runs on YouTube's caption text the same way it runs on any web page), but not on Netflix. If your immersion is mostly on those streaming platforms, Migaku is the better fit.
Best for: intermediate-to-advanced Japanese learners who read native Japanese text on the web and want lookup plus SRS in one tool without configuring Yomitan and maintaining a separate Anki deck.
2. Renshuu
Renshuu is a Japanese learning app built by a small family team in the United States. It covers grammar explanations, vocabulary building, kanji study, and JLPT preparation in a single structured experience. The free version is unusually generous, and the paid Pro tier removes daily limits and adds extra schedules.
Price (May 2026): Free with full core functionality. Pro is around 5 USD per month (verify on renshuu.org).
Strengths.
-
Cleanly structured lessons by JLPT level (N5 through N1) with example sentences and audio.
-
No AI-generated content. Everything is hand-written by the team, which is increasingly rare in 2026.
-
Covers hiragana and katakana for absolute beginners and goes up to advanced grammar without forcing you to switch apps.
-
Active, supportive community.
Limitations.
-
Not designed for in-page popup lookup while you read native Japanese material on the web.
-
The interface is functional rather than polished. If you are used to the visual finish of a modern language learning app, the learning experience can feel utilitarian.
-
Mobile is fine, desktop browser is the primary surface.
Best for: post-Duolingo learners who need grammar and JLPT preparation as the next step. Pairs well with immit for the immersion-reading phase that comes after.
3. Bunpro (with Bunpo as an alternative)
Bunpro is a grammar-focused SRS tool that walks learners through JLPT-level grammar one point at a time with clear grammar rules, example sentences, and practice exercises covering verb conjugations and sentence patterns. Bunpo (different app, similar idea) is a comparable option if Bunpro's interface does not suit you.
Price (May 2026): Bunpro is around 5 USD per month or 40 USD per year, with a one-month free trial.
Strengths.
-
Pure grammar SRS. You see one grammar point, you drill it, you move on. Combat the forgetting curve at the grammar level.
-
JLPT N5 through N1 progression is clearly laid out.
-
Cross-references Tae Kim's Guide and other free Japanese resources, so you can dig deeper without leaving the lesson.
Limitations.
-
Narrow scope. Bunpro does grammar SRS well and does not try to be a full Japanese course.
-
Vocabulary support exists but is secondary. If you want vocabulary SRS, use immit or Anki, not Bunpro.
Best for: learners who already understand the basics of Japanese grammar but want a structured drilling system to keep grammar points retained as new ones come in.
4. WaniKani (with Kanji Study as a free companion)
WaniKani is the structured kanji curriculum app from Tofugu. It teaches around 2,000 kanji characters and roughly 6,000 vocabulary words through a radical-then-kanji-then-vocabulary mnemonic system, paced by an SRS schedule. Kanji mastery is essential for Japanese reading literacy, and WaniKani is the most-recommended structured path through it.
Price (May 2026): First 3 levels free. Subscription is 9 USD per month, 89 USD per year, or 300 USD lifetime. Verify on wanikani.com before subscribing.
Strengths.
-
The mnemonic system actually works. Most users we know who finished WaniKani retained the kanji well beyond the app.
-
Pacing is forced, which removes decision fatigue.
-
Tofugu's writing voice is warm and learner-friendly.
Limitations.
-
Linear order. You cannot easily jump ahead or skip kanji you already know.
-
Vocabulary inside WaniKani is selected to teach the kanji, not the other way around. Use a separate tool for real-immersion vocabulary.
-
Roughly 1.5 to 2 years to complete at a steady pace.
Best for: learners who want a structured, set-it-and-forget-it path through the 2,000-plus kanji characters that make up the reading-literacy threshold. WaniKani owns this slot. Do not look for a substitute.
Kanji Study is a free app (available on the Google Play Store, with a paid Pro upgrade) that assists learners in kanji lookup, shows stroke order, and allows users to study and search by radicals, which helps in memorizing complex Japanese characters. Effective kanji learning often involves understanding stroke order, which is crucial for writing practice and for memorizing characters correctly. Kanji Study is the right complement to WaniKani if you want a free reference and a stroke-order drill on the side, and it doubles as a basic practice surface for the kanji you have not started learning systematically yet.
5. Anki
Anki is the universal spaced repetition system. It has been the backbone of the Japanese immersion community for over a decade and the FSRS algorithm added in late 2023 reduces review load by roughly 20 to 30 percent at the same retention level. Many Japanese learning apps (including Memrise and others) use spaced repetition algorithms inspired by or compatible with Anki.
The reason SRS works is well supported by cognitive science. Spaced repetition reviews new vocabulary at increasing intervals timed to combat the forgetting curve, which moves words from short-term to long-term memory more efficiently than massed practice. The effect is biggest when the review intervals are tuned to your individual recall pattern, which is what modern SRS schedulers (Anki's FSRS, immit's built-in FSRS) try to do.
Price (May 2026): Free on desktop (Windows, Mac, Linux) and free on Android (AnkiDroid). The iOS app is around 25 USD as a one-time purchase that funds the project.
Strengths.
-
Maximum control. You can build any card type, any field structure, any review schedule. Whatever you can imagine, Anki can probably do.
-
Shared decks for Japanese exist for nearly every popular textbook, JLPT level, and immersion source.
-
FSRS algorithm is the best open-source SRS scheduler available.
Limitations.
-
Setup tax is real. Most learners we have talked to spend hours configuring note types and add-ons before they start studying.
-
The interface is dated. Reviewing cards is functional, not pleasant.
-
Maintaining your deck (adding cards, fixing typos, splitting overloaded cards) is its own ongoing task.
Best for: learners who want maximum control and treat the SRS as part of the hobby. If that does not describe you, Anki is more than you need and a tool like immit (popup lookup plus SRS, no setup) closes the same loop with less overhead.
6. Yomitan
Yomitan is the free, open-source popup dictionary that most of the Japanese immersion community uses. It is the successor to Yomichan and runs as a browser extension on Chrome and Firefox. With the right dictionary files installed, Yomitan is one of the most accurate and customizable lookup tools available.
Price: Free.
Strengths.
-
Free and open source. You can read the code, contribute, fork it. The community trust here is real and earned.
-
Extremely customizable. Multiple dictionaries, custom display, frequency lists, pitch-accent overlays, audio sources, all configurable.
-
Roughly 100,000 active users by community estimates, which means workflows and tutorials are everywhere.
Limitations.
-
No built-in SRS. To save a word for review, you connect Yomitan to Anki through AnkiConnect, which is an extra setup step.
-
Setup is not 30 seconds. Installing dictionary files, picking a card template, wiring up AnkiConnect, and styling the cards takes 30 minutes to a few hours depending on how deep you go.
-
No desktop app, no mobile lookup outside of workarounds.
Best for: the configuration-loving Japanese learners who treat their tooling stack as part of the craft. If you want Yomitan's lookup but want SRS built into the same tool with no AnkiConnect wiring, immit is the substitution.
7. Migaku
Migaku is a commercial Japanese learning app (and now a multi-language app) that integrates with Netflix, YouTube, Disney Plus, Reddit, and several other surfaces to let you mine vocabulary from video subtitles. Migaku also ships Migaku Academy 1, a structured roughly-6-month N5-to-N3 course covering around 1,500 words plus grammar, plus a separate Kanji track.
Price (May 2026): Approximately 9 USD per month (Standard, yearly billed) up to around 15 USD per month (Early Access, yearly billed), with a lifetime option around 399 USD and a 14-day money-back period. There is no permanent free tier. Verify current pricing at migaku.com/pricing before subscribing.
Strengths.
-
Migaku Academy 1 is a real reason to pay for Migaku if you want a structured Japanese course with curriculum and progression. immit does not have a course like this and does not plan to. If a structured course is what you need, Migaku Academy 1 is the right answer.
-
Video subtitle workflow on Netflix and YouTube is the best in the category.
-
Polished UX across desktop and mobile.
Limitations.
-
No permanent free tier, which raises the barrier compared with immit, Yomitan, and Anki.
-
The default Japanese dictionary is JP-EN only. Monolingual J-J dictionaries exist but are a manual install.
-
The Japanese-specific feature set is narrower than the all-in-one branding suggests. For example, pitch accent and personal subtitle import are not advertised on the homepage as of May 2026.
Best for: learners who specifically want a structured course (Academy 1) plus video-subtitle mining and are happy paying around 9 USD per month or more on an annual plan. If you do not need the course and want lookup-plus-SRS for reading native Japanese text on the web, immit covers that workflow free, with an account-free install.
8. Satori Reader
Satori Reader provides naturally written Japanese stories with built-in translations, audio, and grammar breakdowns. It sits in the awkward gap between graded readers (which feel artificial) and native material (which feels impossible). Stories are written for learners but are not babied.
Price (May 2026): Around 9 USD per month, with a limited number of free articles.
Strengths.
-
Story-based, which makes reading comprehension and vocabulary retention noticeably easier than flashcards alone. Contextual learning works.
-
Built-in translations and grammar breakdowns mean you do not need to switch to a separate dictionary mid-story.
-
Audio recordings are professional and let you build listening skills at the same time as reading.
Limitations.
-
A walled garden. Vocabulary you learn in Satori does not automatically end up in your other tools, although you can export.
-
Once you have outgrown the article catalog, you will need to move to fully native material.
Best for: the bridge phase between textbook Japanese and fully native reading. Many learners pair Satori Reader with immit (for the moments inside Satori where you want a popup lookup the app does not provide) and with Anki or immit for retention of the vocabulary you encounter.
9. italki and HelloTalk (for conversation practice)
Conversation practice is the one phase no app can fully replace. Developing conversational fluency in Japanese requires human interaction, and italki and HelloTalk are the two most-used platforms for getting it.
italki is a marketplace for native Japanese speakers acting as professional teachers and community tutors. Pricing varies by tutor, roughly 10 to 30 USD per hour for community tutors and higher for credentialed professional teachers. The strength is personalized lessons, structured speaking practice, and immediate feedback on grammar and pronunciation. Pitch-accent coaching, business Japanese, JLPT speaking section preparation, all reachable through the marketplace.
HelloTalk is a free language exchange app that connects you with a language exchange partner who is a native Japanese speaker learning your native language. You correct each other's writing, send voice messages, and chat. The strength is that it is free and lower-stakes than a paid lesson; the limitation is that the exchange quality depends entirely on the partner.
Best for: italki when you can pay for a structured lesson and want measurable progress on speaking. HelloTalk when you want free, casual practice speaking and writing with native Japanese speakers.
These two are not direct substitutes for the lookup-and-SRS work that immit, Anki, and Yomitan do. They complement it. You learn vocabulary and grammar with the SRS tools and you stress-test it in conversation.
Other popular Japanese learning apps we left off, and why
This is not a complete catalog. A few apps come up in nearly every "best apps for learning Japanese" listicle and we left them off this list on purpose.
Duolingo
Good for building a daily study habit at the absolute-beginner stage. Gamified apps like Duolingo do not teach complex sentence structures, and at intermediate level the curriculum runs out of value. Most users we know who quit Duolingo for Japanese did so because they hit a ceiling around late A2. If you are post-Duolingo, see Renshuu or Bunpro instead.
LingoDeer
Often called the best all-in-one Japanese app because of its specific focus on Asian languages. LingoDeer is a comprehensive Japanese course for beginners and intermediate learners, offering a gamified experience that enhances user engagement while providing thorough instruction in grammar and vocabulary. We left it off the main ranking because immit's target reader is past this phase. For the absolute beginner audience, LingoDeer is a reasonable pick and is available on the Google Play Store and the App Store.
Human Japanese
Human Japanese is an interactive Japanese course in textbook form, available as a one-time purchase app for desktop, iOS, and Android. It provides thorough explanations of Japanese grammar, including reading and writing instructions, and a strong introduction to the Japanese writing system, making it suitable for beginners. Same reason as LingoDeer for leaving it off the main list: the target reader for this post is past the beginner Japanese curriculum. Human Japanese remains a good first-textbook recommendation for those who want a no-subscription option.
Pimsleur Japanese
Pimsleur Japanese is an audio-based learning approach that emphasizes speaking and listening skills, ideal for learners who want practical phrases for travel or want to practice speaking Japanese from day one. It is useful in the early months. We left it off because by the intermediate phase the audio-only curriculum runs thin and a tool like italki delivers more value per hour of speaking practice.
Rosetta Stone
A general language learning app with phonetic alphabets and image-based methodology, built to teach many languages from one template. It is not specifically built for Japanese and gets outperformed at every phase by Japanese-specific tools.
Tae Kim's Guide to Learning Japanese
Not an app, but worth naming. Tae Kim's Guide is a comprehensive free online resource that covers various aspects of Japanese grammar, including verb conjugations and sentence structure. Many of the apps above (including Bunpro) cross-reference it. If you want a free grammar reference, Tae Kim's Guide is the canonical pick.
Memrise
Originally a strong vocabulary SRS competitor. The Japanese catalog is uneven in 2026 and the spaced repetition implementation has drifted from where it started. Use Anki or immit for vocabulary SRS instead.
Other Japanese resources worth knowing
A few other resources come up often enough that they are worth naming, even though we did not rank them as best apps in their own right.
Jisho.org is the most widely used free Japanese-English dictionary on the web. It is fast, has clean English translations, and shows kanji characters with their stroke order, radical breakdown, and JLPT prep tagging. Most apps in this list cross-reference Jisho one way or another. It pairs with immit cleanly: use immit for in-page popup lookup while you read, and use Jisho when you want a full dictionary entry on a single word.
Tofugu is the team behind WaniKani and the largest English-language writing operation on Japanese language and culture topics. The Tofugu blog covers basic Japanese grammar, kanji learning style, hiragana and katakana drills, JLPT prep guides, and cultural context essays. It is one of the better other resources for free reading practice, especially in the beginner-to-intermediate range.
Mochi, Drops, LingQ, and a long tail of other apps on the Google Play Store and App Store cover specific niches (vocabulary flashcards, character drills, immersion-reading wrappers). None of them displaced the apps in our main list, but if a specific learning style (audio-first, image-first, gamified, no-keyboard) is non-negotiable for you, browsing the store with that filter in mind is a reasonable way to find something that sticks. Most apps in the long tail share the same underlying spaced repetition principles, so the teaching style and interface are what differentiate them in practice. People who enjoy learning languages in general (Spanish, Korean, German on top of Japanese) often end up with one tool per language, while learners focused only on Japanese benefit from picking specialists like the ones in our main list.
Japanese podcasts and YouTube channels (Nihongo Con Teppei, JapanesePod101, Bilingual News, Game Gengo) are some of the best free Japanese resources for listening practice. They are not flashcard apps and they do not show up in app-store roundups, but they sit naturally next to immit in the immersion stack: you listen, you encounter a word, and you save it the next time you read it on a related web page.
The point of naming these is so you know the apps in our list are not the entire universe. They are the ones we found ourselves recommending to other Japanese learners most often, but study Japanese the way that fits how you actually learn, not the way a roundup tells you to.
How to combine these Japanese learning apps into an immersion stack
A practical stack looks roughly like this for a learner moving from beginner to intermediate:
-
Renshuu or Bunpro for grammar and JLPT progression.
-
WaniKani for the 2,000-plus kanji curriculum.
-
immit for popup dictionary lookup and integrated SRS while you read native Japanese text on the web. The Chrome extension is all you need; the desktop app is optional, and a free account syncs your saved vocabulary across devices.
-
Satori Reader for the graded-reading bridge between textbook Japanese and fully native material.
-
italki or HelloTalk for conversation practice with native speakers.
Anki sits as an optional layer for learners who want maximum SRS control. Yomitan sits as a substitute for immit's lookup if you specifically want the open-source customization route and are comfortable wiring up AnkiConnect.
The point of the stack is not to use every app every day. The point is to have one named tool for each phase so that when you sit down to study you know what to open. Most learners we know spend more time on the discovery-plus-review loop (steps 3, 4) than on the curriculum loop (steps 1, 2) after the first year.
A note on retention. Contextual learning, which means encountering vocabulary in real sentences and real-life situations rather than as bare word pairs, is one of the highest-leverage habits you can build. Engaging with Japanese media (manga, music, anime, games, novels, news) reinforces language learning in enjoyable ways and makes new vocabulary stick because the words show up wrapped in story, sound, and image, not on a flashcard alone. The tools in the stack above are there to capture what you encounter in that media, not to replace the media itself.
How to choose the best Japanese app for you: a decision tree
Pick by your current bottleneck.
-
Bottleneck: I just finished Duolingo and grammar feels shaky. Start Renshuu (free) or Bunpro (around 5 USD per month).
-
Bottleneck: I can read kana but kanji feels like a wall. Start WaniKani. Add Kanji Study free on the side for stroke order.
-
Bottleneck: I can read short articles but I lose half the words by the next day. This is the immit slot. Lookup plus SRS in one tool closes the discovery-to-review gap.
-
Bottleneck: I read fine but I cannot speak. italki for paid lessons, HelloTalk for free language exchange.
-
Bottleneck: I bounce between tools and never finish anything. Cut your stack. Pick one grammar tool, one kanji tool, one vocabulary-from-reading tool (immit), one conversation tool. Stop adding apps until those four are habitual.
How Japanese learners actually use these apps
A few patterns show up consistently in community threads on r/LearnJapanese, in TheMoeWay and Refold Discord servers, and in conversations with intermediate Japanese learners we have talked with informally.
Most learners use two to four apps at once, not one
Almost nobody who is making real progress runs a single Japanese app. The typical stack is one app for grammar (Renshuu, Bunpro, or Tae Kim's Guide), one for kanji (WaniKani or Kanji Study), and one for immersion vocabulary (immit, Anki, or Yomitan plus Anki). A combination of apps is highly recommended for achieving Japanese fluency, and the consensus across the immersion community holds up the same way.
The "best Japanese course" question is the wrong question
Many learners spend months looking for the best Japanese course online when what they actually need is an immersion workflow. A Japanese course (LingoDeer, Migaku Academy 1, Human Japanese) is useful up to roughly N4, then the curve flattens. After that, the learners making the most visible progress in community threads are the ones reading native Japanese text every day and using a tool like immit to capture new vocabulary as they go.
Conversation practice is the most undervalued layer
Most apps we covered above focus on input (reading, listening, recognition). Learners who can read at N3 but cannot speak in basic conversation are common in r/LearnJapanese write-ups. If you want to actually speak Japanese, regular italki sessions or daily HelloTalk practice is the layer that closes the gap. No flashcard app is a substitute for talking with native Japanese speakers.
FAQ
What is the best app for learning Japanese in 2026?
The best app for learning Japanese depends on which phase you are in. For grammar after Duolingo, use Renshuu (free) or Bunpro (around 5 USD per month). For kanji curriculum, use WaniKani (9 USD per month or 300 USD lifetime). For popup dictionary lookup plus integrated SRS during immersion reading, use immit (free). For deep-control flashcard review, use Anki (free desktop). For conversation practice with native Japanese speakers, use italki or HelloTalk. No single app delivers fluency; a combination of apps is highly recommended.
What is the best free app for learning Japanese?
For grammar and JLPT preparation, Renshuu has the most complete free tier in the category. For popup dictionary lookup plus integrated spaced repetition, immit is free and covers the full lookup and SRS loop with no account required. For traditional flashcard SRS, Anki is free on desktop and Android. Yomitan is free for popup lookup but requires Anki-plus-AnkiConnect for retention.
Is Duolingo good for learning Japanese?
Duolingo is a good app for building a daily study habit at the absolute-beginner stage. It does not teach complex sentence structures and most intermediate learners outgrow it within a few months. If you are looking for a step-2 Japanese course after Duolingo, Renshuu and Bunpro are the natural next picks.
What is the best app for Japanese vocabulary specifically?
For immersion-based vocabulary building (vocabulary captured from what you actually read), use immit. For self-built decks with maximum control, use Anki. For JLPT-tagged vocabulary lists tied to a curriculum, use Renshuu. Apps like Memrise also use spaced repetition algorithms but the Japanese catalog quality has drifted.
How is immit different from Yomitan?
Yomitan is a free, open-source popup dictionary with no built-in SRS. To save a word for review with Yomitan, you connect it to Anki through AnkiConnect, which is an extra setup step. immit is an all-in-one tool that combines the popup lookup and the spaced repetition system in one place, with no AnkiConnect wiring and no setup beyond installing the extension. Yomitan is the right choice if you want maximum customization and enjoy configuring tools; immit is the right choice if you want lookup plus SRS to work the moment you install it.
Is Migaku worth it compared to immit?
Migaku is worth paying for if you specifically want Migaku Academy 1, the structured roughly-6-month N5-to-N3 course, or if you specifically want video-subtitle mining on Netflix and YouTube. immit does not have a course and does not plan to. immit's wedge is the reading-on-the-web workflow with popup lookup plus integrated SRS free with no account required (syncing across devices is free too with an optional account). If your reading is mostly web text and articles, immit covers the loop. If your reading is mostly video subtitles and you want a curriculum, Migaku covers more of your needs.
Can I use both WaniKani and immit?
Yes. WaniKani teaches the kanji curriculum with mnemonics, around 2,000 characters paced by SRS. immit handles vocabulary you encounter while reading native Japanese text on the web. The two tools cover different phases and do not overlap. WaniKani for the kanji curriculum, immit for the immersion-vocabulary phase that comes after.
What app should I use after Duolingo for Japanese?
After Duolingo, most learners need three things: grammar, kanji, and vocabulary from real reading. The 2026 answer chain is Renshuu or Bunpro for grammar, WaniKani for the structured kanji curriculum, and immit for popup dictionary lookup plus integrated SRS during immersion reading. Add italki or HelloTalk when you are ready to practice speaking with native Japanese speakers.
About this post
Written by Ben, an American intermediate-advanced Japanese learner, and Serena, a Japanese-native product designer. We co-built immit because we could not find a tool that handled both popup dictionary lookup and spaced repetition without complicated configuration. The list above reflects what we use, what we have tested, and what we hear from the learners we talk with in the immersion community.
All prices and feature claims are as of May 2026. Verify each app's current pricing on its own homepage before subscribing.
If you want to try the immersion-reading workflow this post describes, add immit to Chrome free. No account required, works offline, free.
