Who this site is for
LavaJapanese publishes learning materials in English, Vietnamese and Korean. Available lessons vary by language. Read a grammar explanation, try the related questions, and return to your saved answers for review. Translations are linked only when the lesson is available in that language.
Editorial policy
Our lessons explain meaning, form, common mistakes, and examples. The expanded lessons also include original practice and answer explanations. References are linked so you can check the source. Level labels are study guides; LavaJapanese is an independent learning site and is not an official JLPT provider.
How we describe evidence
App guides distinguish official feature information from our study suggestions. A document-based guide is not presented as a hands-on product test. Course coverage, study-time examples, and personal proficiency are different measures. We do not promise an exam result or a fixed time to fluency.
Writing and review
AI tools may assist drafting, translation, and editing. This does not establish expert or native-speaker review. Named author or reviewer credits are included only when recorded; no teaching qualification should be inferred from the site name. Substantive changes receive an updated date.
Corrections
If a sentence, translation, source, or link needs correcting, send the page URL, the passage, and your suggested correction. This helps us check the issue and update the relevant language versions.
