How the practice material is built.

Scope

The site covers N5 through N1 with 469 original positions across five full mock tests, 20 focused practice routes, and 149 listening tracks. Each level also has a 12-week study plan that connects practice results to a weekly routine.

“Original” means the questions, passages, listening scripts, answer choices, and explanations were created for this site. They are not copied from past JLPT papers or the official sample workbook. The Japan Foundation and Japan Educational Exchanges and Services do not endorse or review this material.

How test structure is modeled

The level sections, time limits, and question families are based on the official JLPT test-section descriptions and guidebook. Official sample questions are consulted to understand interaction and format, not as a source of reusable question text. Because live item counts may vary, the mock tests are practical simulations rather than replicas of a particular exam form.

• Official sample-question index
• Official JLPT frequently asked questions

Question construction

Each item starts with a level, skill, and question-family target. Vocabulary items test reading, orthography, contextual fit, or paraphrase. Grammar items test form, sentence construction, or text flow. Reading items use original passages with a defined purpose such as detail retrieval, inference, comparison, or information search. Listening items use original scripts and task-specific prompts.

Every question includes an answer and explanation. Practice drills reveal the explanation after each response; full mocks hold feedback until the result so the test remains a measurement rather than a guided lesson.

Automated release checks

The repository’s content audit rejects or flags issues including:

• empty prompts, answers, explanations, or answer choices;
• duplicate choices, duplicate question identifiers, and repeated stimuli;
• answers that do not exactly match an available choice;
• questions assigned to the wrong level, skill, or mock-test section;
• missing reading passages, listening scripts, or listening media;
• placeholder copy, incomplete question counts, and strongly biased answer positions;
• missing provenance and review-status metadata.

These checks verify structure and consistency. They do not prove that every Japanese expression is the most natural choice, and they are not represented as native-speaker certification. If an issue is found during maintenance, the relevant item and content version can be corrected and run through the same checks again.

Reference inventories and licenses

The JLPT has not published exhaustive vocabulary, kanji, or grammar lists for the current test. The site therefore describes its reference material as curated study targets, not an official syllabus. Vocabulary inventories are based in part on the MIT-licensed elzup JLPT word list. Kanji inventories were cross-checked against the MIT-licensed AnchorI JLPT kanji dictionary and then adapted for the site’s level targets. License notices are retained with the source data.

Listening audio

Listening tracks are synthesized from the site’s original Japanese scripts. They are intended for question practice, not as examples of every regional accent or conversational voice. Practice mode allows replay and slower playback; strict mode provides a single uninterrupted play to make the task more demanding.

Scoring and result claims

The official JLPT uses scaled scoring, and the scale for a live test cannot be reconstructed from raw answer accuracy. Results on this site therefore identify raw performance and clearly label any estimated score or pass indication as unofficial. The useful output is the breakdown by skill and section: it tells a learner what to practice next without claiming to predict an official result.

Versioning and corrections

Each question has a stable content identifier and the question bank has a published content version. This makes corrections traceable: an identified issue can be reproduced, updated in the relevant question or explanation, and rechecked by the automated release audit before the next version is published.
