Learn Japanese Free: How to Pick Reliable Resources
There is no single best free way to learn Japanese. Spaced-repetition apps are for memorizing vocabulary and kanji, grammar reference sites are for understanding structure, podcasts and video content are for listening, and language exchange communities are for speaking. Most learners who make steady progress use two or three of these at once rather than hunting for one app that does everything.
The mistake to avoid is treating “free” as a single category. A flashcard app and a grammar textbook site solve completely different problems, and neither one will teach you to hold a conversation. Knowing what each type of resource is for will save you from switching apps every few weeks out of frustration that it “isn’t working.”
What free resources actually exist
Free Japanese learning material falls into a handful of clear types.
Spaced-repetition and flashcard apps. These drill vocabulary and kanji using algorithms that show you a word right before you’re likely to forget it. They are excellent for building a base of a few thousand words and for working through the kanji needed for reading. They are not designed to teach grammar or get you speaking, and many learners plateau here if flashcards are the only thing they do.
Grammar reference sites. These lay out sentence patterns, particles, and verb conjugations with example sentences, roughly the way a textbook chapter would. They’re the right place to go when a sentence you’ve encountered doesn’t make sense and you need the rule explained, not just translated.
Listening and immersion content. Podcasts aimed at learners, graded video series, and Japanese-language YouTube channels fall here. These build the ear for natural speech rhythm and intonation, which textbooks and apps generally cannot do on their own. Content made for learners usually speaks more slowly and repeats vocabulary; content made for native Japanese audiences is harder but exposes you to how people actually talk.
Communities and language exchange. Forums, subreddits, Discord servers, and exchange apps that pair you with a native Japanese speaker learning English (or another language) give you a place to ask questions and get corrected. These are where speaking and writing practice actually happens, since none of the other categories require you to produce the language yourself.
University and institutional courses. Several universities and language organizations post full beginner courses online, sometimes as structured lesson sequences with audio and workbooks. These tend to be more rigorous and better sequenced than app-based learning, though they move slower and require more discipline to finish.
How to match the resource to the goal
If your goal is to read menus, signs, and simple text while traveling, prioritize a vocabulary app and a short grammar reference, and don’t worry about speaking practice yet. Recognition matters more than production for a short trip.
If your goal is to pass a JLPT level, grammar reference sites and vocabulary apps built around JLPT levels are the most direct route, since they organize material the way the test organizes it. Immersion content helps with the listening section specifically.
If your goal is to hold conversations, flashcards and grammar sites alone will not get you there. You need a community or exchange partner, because speaking is a skill that only improves with practice speaking, not with more passive review. Expect this part to feel the most uncomfortable, since mistakes happen in front of another person rather than privately in an app.
If your goal is general fluency over a year or more, a structured course gives you the sequencing that mixing random free tools tends to lack. Many learners who rely only on apps and videos end up with gaps: strong vocabulary but shaky grammar, or good reading but no ability to produce a sentence out loud. A course, even a free one, forces you through material in an order that builds on itself.
Situations that make the difference concrete
If you’re starting from zero and feel overwhelmed by choice, pick one grammar-focused course or reference site as your spine and add a vocabulary app alongside it. Don’t try to use five apps simultaneously in week one.
If you already know basic grammar but freeze up when a Japanese person speaks to you, the gap is almost certainly listening exposure and speaking practice, not more flashcards. Shift time toward podcasts or shows made for native speakers and toward an exchange partner, even if progress on vocabulary apps slows down as a result.
If you’re preparing for a trip in a few months and want practical phrases rather than grammar theory, a phrasebook-style app or a short course aimed at travelers will get you further than a general app built for long-term fluency.
If you’ve been using the same flashcard app for months and feel like you’ve plateaued, the likely issue is that flashcards alone can’t teach you to use words in sentences. Add a grammar resource or start reading simple native text alongside the reviews.
What to check before relying on a resource
Free does not mean equally accurate or equally current. Grammar explanations on forums and older blog posts can be outdated or simply wrong, so cross-check anything that seems off against a second source, ideally one maintained by a language institution or a well-known textbook publisher’s companion site.
Community advice varies in quality depending on who’s answering. A fellow learner’s explanation of a grammar point is not the same as a teacher’s, even if both are offered with confidence. Treat community answers as a starting point for further checking rather than a final word, especially for anything related to formal or business Japanese.
Apps change their free tiers over time. A feature that’s free today may move behind a paywall later, and some apps that market themselves as free actually gate the most useful content, like detailed example sentences or audio, behind a subscription. Read what’s actually included before building your routine around one app.
Finally, pace yourself around what you can sustain. A free resource you use for fifteen minutes every day will teach you more over a year than an ambitious combination of five tools you abandon after three weeks. Pick based on what fits your schedule, not on which resource looks the most complete on the day you find it.
