How we select resources
We help English-speaking adults choose resources for learning Japanese and put them into a workable routine. The directory combines a review of providers’ public pages with research on learning techniques. It is a starting point for your choices.
Research reviewed: . This edition is based on desk research, not long-term trials of every product. Features, access and prices can change; check the provider before signing up.
What a recommendation means
We consider what a resource helps you practice, the support it offers, how it fits a learning stage, its access model and what you may need alongside it. Our suggested combinations and stage filters are editorial judgments. They are not a certification of course level or an JLPT alignment.
Choose a manageable combination and adjust it when you find a gap. Finishing a course, maintaining a streak or recognizing words on a screen does not, by itself, demonstrate speaking or listening ability.
Our Japanese edition
This edition teaches standard Japanese for English-speaking adults. Hiragana and katakana support the first lessons; explicit kana readings accompany kanji. Our curriculum is not a certified JLPT course. Lessons and original examples were authored with AI assistance and have not undergone an independent teacher’s complete editorial review.
Japanese verbs change for tense, negation, and politeness, but do not agree with a subject’s person or number. Particles mark relationships, and the predicate normally finishes the clause. Long vowels and consonants matter. Kana readings do not encode pitch accent; generated speech is a listening aid rather than a pronunciation assessment.
Our language research draws on the Japan Foundation’s Irodori grammar notes, Marugoto’s introduction, Tokyo University of Foreign Studies’ mora lessons, and the University of Tokyo’s OJAD. Teaching explanations are original; these references do not imply endorsement.
The larger vocabulary and verb libraries combine original teaching material with licensed dictionary and sentence data. Their attribution, selection methods, and review limits are documented in the flashcard sources and verb sources.
Three kinds of evidence
- Official product descriptions establish what a provider says it offers, including features and access. They are not independent tests of learning outcomes.
- Provider research may offer useful results. We identify provider-conducted or funded work when citing it, including the skills assessed and the limits of its findings.
- Independent research on techniques informs the learning pathway. Evidence for spaced practice, reading or feedback does not prove that every product using that technique works equally well.
Peer review and independence are different questions: publication in a journal does not remove an author’s connection to a provider. We do not turn a narrow test result into a claim that a product makes someone fluent.
Learning stages and scope
Our four stages describe practical learning goals, from introductions to extended conversation. They are not official exam levels. Reading, listening, speaking and writing may develop at different rates, so use the checkpoints to identify a next step rather than assign yourself one definitive level.
The activity mix is our synthesis of the sources below, not a single experimentally validated course. It includes understandable listening and reading, deliberate study and recall, communication with feedback, and practice using familiar language more easily. There is no guaranteed number of days or hours to fluency, and no single resource combination is best for everyone.
Free, partly free and paid
The directory is free to use. Listed resources may offer free material, a free tier with paid features, a limited sample, or paid access. Those differences matter: two sample lessons are a sample, not a free full course. Paid options are included for a specific benefit, such as individual feedback or added structure; their price is not evidence of better results.
Check the access note on each resource and confirm current terms on its website. A listing with an uncertain access detail needs confirmation from the provider before you rely on it.
Research behind the pathway
These sources support the learning principles and checkpoints. They are not comparative reviews of the products in the directory.
Japan Foundation · Irodori
Japanese curriculum reference
A practical communication-oriented reference for Japanese used in everyday life. Its course levels describe the Foundation’s materials; they do not certify this independently authored site.
Japan Foundation · Marugoto Plus introduction
Japanese language reference
Introduces Japanese word order, scripts, grammar, and pronunciation. Used to check the language-specific choices in this edition.
Tokyo University of Foreign Studies · Morae and accent
University pronunciation reference
Explains why morae, long vowels, and dependent sound units matter to Japanese pronunciation. Supports teaching sound length explicitly instead of importing another language’s tone system.
University of Tokyo · OJAD
University pronunciation tool
A research-based accent reference with conjugated-word recordings and prosody tools. Pitch information is word- and form-dependent; automatic predictions still require interpretation.
