After Duolingo Japanese: the 2026 roadmap to actually become fluent
Most English-speaking Japanese learners who finish Duolingo's Japanese course follow a recognizable arc: 6 to 12 months on the tree, the satisfaction of clearing a complete beginner curriculum, then the question of what to do with that foundation. Duolingo Japanese was designed to introduce hiragana, katakana, basic phrases, and beginner sentence patterns, and the course delivers that within its scope. Reading native Japanese, parsing grammar past JLPT N4, and building the 5,000-plus vocabulary base for unsubtitled media are the next things to learn, and they sit outside the course's design. This roadmap is the post-Duolingo stack I wish I'd had on day one: a 12-month, 3-stage path through Renshuu, Bunpro, Anki, Yomitan, and immit, with what to install when, and why. The broader language learning community has converged on this answer chain for serious learners.
Quick answer: Duolingo Japanese is good for getting absolute beginners through hiragana, katakana, basic phrases, and JLPT N5 grammar; for the post-Duolingo path to native reading, add Renshuu (grammar), Anki or immit (vocabulary), and Yomitan or immit (popup-dictionary reading) over the next 12 months at one hour per day.
Yes, Duolingo Japanese is good for one specific job: getting an English-speaking absolute beginner into hiragana and katakana, basic phrases, and beginner sentence patterns through bite-sized daily lessons. As of May 2026, the course covers JLPT N5 grammar in full, much of N4, and some N3 material by the end of the tree, with daily-streak gamification and XP points that reliably keep people opening the app for months. Hiragana and katakana now live in dedicated tabs outside the main learning path. The placement test routes returners past mastered sections, while audio exposure, listening skills, and the speaking exercises tied to basic greetings make up the kana-onboarding flow. For learners whose alternative is "study nothing," that consistency produces more Japanese than any unused textbook on a shelf.
Duolingo's sophisticated gamification system (streaks, XP points, leaderboards, animated rewards) is effective from a habit-formation psychology perspective, and for absolute beginner level learners that habit is half the battle. Using Duolingo for 10 to 15 minutes daily is recommended; its strength lies in building a consistent study habit, not serving as a primary study method.
What Duolingo Japanese is designed to deliver is bounded and clear. The entire course works through repetition: hiragana and katakana drilled until the writing systems become automatic, the high-frequency basic words, particle use, basic verb conjugation, and sentence structures up to roughly 私はりんごを食べました-level complexity. The course also includes some listening practice through native speaker audio and some writing practice through reorder-the-tiles exercises using word banks. Engaging with the course's 'Discuss' section for each question can enhance understanding by letting learners see explanations from more experienced users.
What sits outside that design is also clear. Duolingo relies on repetition rather than explicit grammar instruction, expecting users to absorb patterns through exposure to key grammatical concepts such as the use of particles like wa (は) and ga (が). Duolingo Japanese was not built to teach the roughly 2,000 jōyō kanji needed for adult reading, the 5,000-plus vocabulary base for unsubtitled anime and novels, dense native prose, unscripted native audio, reading native Japanese on the web, accurate Japanese pronunciation past beginner patterns, or the Japanese characters past the kana sets. Open-ended speaking practice with pronunciation feedback is outside the course's design. Duolingo's Video Call feature, free since January 2026, offers scripted AI conversations in Japanese. None of this is a defect; it is the design boundary of a beginner course. Setting realistic expectations is the bridge to the next stack.
Duolingo Japanese is a structured beginner course built around four design choices: bite-sized daily lessons, character-first onboarding through hiragana and katakana, particle-led sentence construction, and gamified retention through streaks. Each of those choices makes Duolingo Japanese very good at producing the result it was designed to produce: a beginner with kana mastery, a working sense of basic grammar, and the habit of opening the app daily. These four choices match the daily routine of language learners studying Japanese.
By the end of the tree, you have a particular and clear set of skills: you have a good grasp of simple sentences and can read NHK Easy News headlines with furigana, follow a short hand-written letter in hiragana and katakana, hold a simple self-introduction, and recognize about 1,350 kanji in context. That is real Japanese. For me, the end of the tree was the point where a manga page with furigana stopped being decoding and started being reading.
What sits outside the design is as specific. Adult-level kanji depth (the roughly 2,000 jōyō kanji set, plus the 5,000-plus reading-required vocabulary that pairs with them) is outside the course's scope. Listening to unscripted native audio (a podcast, an NHK news broadcast at native speed, YouTube videos) is outside the design. Reading a column in the Asahi Shimbun, a contemporary novel, or a research paper requires kanji and vocabulary the course was not built to cover. Extended speaking with feedback past the Video Call's scripted prompts is also outside the course's scope.
The signal that you have reached the design boundary is concrete: you complete one lesson and recognize every word in it, and you can read Duolingo's own stories without translation but stumble on the first paragraph of a Wikipedia article in Japanese. When that happens, the course has delivered what it was built to deliver. The next 9 months of work belong to a different stack.
The post-Duolingo stack is a 12-month, 3-stage path from the end of the Duolingo tree to reading native Japanese on the web at roughly one hour of study per day.
Stage 1 (months 1 to 3): shore up grammar with Renshuu, Bunpro, or Tae Kim's Guide.
Stage 2 (months 3 to 9): build vocabulary with Anki or immit.
Stage 3 (months 6 and beyond): read native Japanese using Yomitan or immit.
This is a shortlist, not a survey. The named tools are the ones I trust from my own time learning Japanese plus consistent recommendations in online communities. Learners with different preferences will have other choices that work; the goal here is a stack that holds together end-to-end, not a complete catalog.
Stages 2 and 3 overlap by design. You start reading once you have the grammar foundation and roughly 1,500 new vocabulary items, and the reading itself drives the next stage of vocabulary acquisition. The rest of this post walks through each stage with the named tools, the actual lessons, and the workflow, with notes on other methods used alongside Duolingo.
Stage 1's goal is finishing N5 grammar and walking into N4 by the end of month 3, so that Stage 2's vocabulary work attaches to a structured grammar map rather than to free-floating words. Duolingo taught those N5 patterns through repetition; Stage 1 is where learning grammar gets the explicit explanations Duolingo's bite-sized format does not include, and the SRS scheduling that makes the patterns stick.
Renshuu (renshuu.org) is the first tool I open in month 1. It is a JLPT-curriculum SRS for grammar, vocab, and kanji, built by a family without venture capital, and the free tier is enough to cover N5 grammar in full. As of May 2026, Renshuu Pro is roughly $7/month or $50/year on the web, with a $110 lifetime option and a separate $4/month iOS plan. The reason Renshuu is the lead recommendation is the curriculum: the JLPT path is structured, the explanations are clear, and the no-AI ethos means the example sentences are written by people who speak the language. Renshuu also schedules cards to learn kanji at the same JLPT levels alongside grammar and vocab.
Bunpro (bunpro.jp) is the JLPT-grammar specialist that pairs naturally with Renshuu. It is organized by JLPT level, and the SRS schedules the grammar patterns themselves the way Anki schedules vocabulary; vocabulary and reading practice were added in recent updates, but grammar remains the core. As of May 2026, Bunpro is $50/year or $150 lifetime. I use Bunpro alongside Renshuu in months 2 to 3 to drill the N4 grammar Renshuu introduces, because Bunpro's grammar-first design produces tighter retention on the grammar set specifically. Bunpro currently catalogs over 800 grammar points across all five JLPT levels for structured grammar study.
Tae Kim's Guide to Learning Japanese is the free written reference behind both. It is not an SRS; it is a structured grammar guide that explains particles, verb conjugation, and the relative clauses Duolingo's format does not introduce by name. I use Tae Kim when Renshuu's flashcards need more explanation.
If I had to pick one tool for Stage 1, it would be Renshuu. Bunpro and Tae Kim sharpen what Renshuu starts.
Stage 2's goal is moving from the high-frequency beginner vocabulary Duolingo Japanese covers to the 4,000-to-6,000 vocabulary base that makes contemporary native material readable. The work is daily SRS review of words you have decided are worth remembering, plus a steady habit of capturing new words from sentences you actually want to read in the target language.
Two tools cover Stage 2 cleanly: Anki and immit. They are different paths to the same outcome, not tools to layer on top of each other.
Anki is free, open-source, and the longest-running SRS in the immersion stack. As of May 2026, it ships with FSRS as the default scheduling algorithm, the upgrade from the older SM-2 that has been the default since November 2023, and FSRS reduces review load by roughly 20 to 30 percent at the same retention. Anki's strength is its plugin ecosystem (AnkiConnect, Yomitan integration, Migaku add-ons, the entire community deck library on AnkiWeb) and its deck format flexibility. The cost of that flexibility is setup: building the workflow, installing add-ons, choosing the deck, and tuning the card template. Anki rewards the work that goes into it.
immit (immit.co) is the tool my wife and I built after running the Yomitan-plus-Anki workflow for two years and looking for something that did both jobs in one install. It is a popup Japanese dictionary with built-in spaced repetition, available as a Chrome extension, with an optional desktop app for Mac, Windows, and Linux. It is free (no account required) and covers the full lookup-and-save loop, offline; syncing across devices is free too with an optional account. The lookup is hover-fast, the SRS is FSRS, built in, and there is no AnkiConnect bridge to maintain because the dictionary and the SRS live in the same tool.
Pick Anki if the configuration depth is part of the appeal and you already have a deck plan. Pick immit if you want the lookup-to-SRS loop to start working in one install. A separate post on Anki alternatives for Japanese learners walks through other Stage 2 options if neither of these fits.
Stage 3 is the point where reading becomes the primary engine of vocabulary acquisition. You read the news, manga, novels, blog posts, or game scripts you actually want to read; you hover or click words you do not know; you save the worth-remembering ones to SRS; and the next morning the SRS feeds them back to you. The grammar foundation from Stage 1 makes the sentences parse. The vocab base from Stage 2 covers the common words. Stage 3 fills in the rest by exposure, one paragraph at a time.
Two tools cover the popup-dictionary side of Stage 3.
Yomitan (yomitan.wiki) is the free, open-source, browser-extension popup dictionary that the Japanese immersion community has been recommending for years. It hovers definitions in milliseconds, supports custom dictionaries, exports cards to Anki via AnkiConnect, and as of May 2026 the Manifest V3 transition is complete so it runs on current Chrome. Yomitan is the hover-lookup tool r/LearnJapanese and TheMoeWay regulars consistently recommend, and the customization depth is the reason. The cost is configuration: installing the dictionary files, AnkiConnect, and Anki, then building the card template. Yomitan has over 100,000 users across Chrome and Firefox; that is the size of the audience that values the customization enough to walk through the setup.
immit (immit.co) is the substitution path for Stage 3 when you want Yomitan-grade lookup without the Anki bridge. The popup dictionary is the same hover-fast format, and the SRS that captures the saved word is built into the same tool, so there is no AnkiConnect, no Anki deck, no separate card template. It is free, as above.
If you love Yomitan's customization and you are willing to maintain Anki alongside it, that is a valid Stage 3 setup. If you want Yomitan-grade lookup in one install with SRS already in the same tool, that is immit. The best Japanese learning app comparison post covers other reading-stack options for learners who want to weigh more candidates.
The fastest answer to "what should I use after Duolingo Japanese in 2026" is a stage-gated stack. Use Renshuu in months 1 to 3 to finish N5 grammar and walk into N4, with Bunpro alongside for grammar SRS and Tae Kim's free grammar guide as a written explanation layer. Use immit in months 3 to 9 to build the vocabulary base and run the SRS without configuring Anki, or use Anki if you already have a deck plan and want plugin-ecosystem depth. Use immit again in months 6 and beyond as the popup dictionary for reading native Japanese, or use Yomitan plus Anki if customization depth is more valuable to you than a single install.
If you want a structured curriculum instead of a self-directed roadmap, Migaku's Academy course (Standard tier ~$9/month or Early Access ~$15/month, yearly billed, as of May 2026) is what paying immersion learners cite for the structured path; I would point a learner toward it if the immit stack does not fit. Everything else in this stack is free or has a free tier; the entire roadmap can run at $0 with paid upgrades only where they remove friction.
Is Duolingo enough to learn Japanese on its own? Duolingo Japanese on its own delivers kana mastery, N5 grammar, and early N4 patterns within its design as a beginner curriculum. The course was not built for adult-level kanji, native reading, unscripted listening, or free-form speaking. Those targets need separate tools. The short answer is "yes, scoped to the beginner stage; no, as a standalone path to fluency in the Japanese language."
What should I do after finishing the Duolingo Japanese tree? Move into a 3-stage post-Duolingo stack: shore up grammar with Renshuu in months 1 to 3, build vocabulary with immit or Anki in months 3 to 9, and read native Japanese with immit or Yomitan plus Anki from month 6 onward. Stages 2 and 3 overlap because reading drives further vocabulary acquisition. The path runs roughly 12 months at one hour of study per day.
How long does the post-Duolingo path to reading native Japanese take? At roughly one hour of focused study per day, the typical post-Duolingo path to comfortable reading of native material runs 9 to 15 months. The Foreign Service Institute classifies Japanese as Category IV, the most time-intensive category for native English speakers, with about 2,200 hours to professional working proficiency. Romance languages like Spanish or French sit in FSI Category I at roughly a quarter of that time; other Asian languages like Korean share Category IV with Japanese. Reading native unsubtitled material sits earlier in that curve. Doubling daily study time compresses the path; halving it roughly doubles it.
Is Renshuu or Bunpro better for grammar after Duolingo? Both work for post-Duolingo grammar; the right choice depends on whether you want a structured curriculum or pure grammar-SRS drilling. Renshuu is the JLPT-curriculum tool that handles grammar, vocab, and kanji in one app with a generous free tier and a no-AI ethos. Bunpro is the JLPT-grammar-anchored SRS with newer vocab and reading additions. In my own path I used Renshuu as the lead and added Bunpro in months 2 to 3 for tighter retention on N4 grammar.
Where does immit fit in this stack? immit covers Stage 2 (vocabulary building) and Stage 3 (popup-dictionary reading) as a single tool, substituting for the Yomitan-plus-Anki workflow widely used in the immersion community. It is free (no account required) and handles offline lookup and FSRS review; syncing across devices is free too with an optional account. immit is not designed for Stage 1 grammar work, which is what Renshuu and Bunpro handle.
If the Stage 2 and Stage 3 lookup-to-SRS loop in one install fits your post-Duolingo plan, the Chrome extension is free with no account required; there is no paid plan. If a different shape of stack fits better, the named tools above are the ones I would trust, with other resources linked throughout the post.
