How we build our content

We want every explanation and practice question on this site to be something you can trust. Here's exactly how our content is made and checked.

Where the data comes from

Our grammar, vocabulary, kanji and example sentences are built on a structured database compiled from open and public-domain Japanese language resources — including dictionary data (JMdict/KANJIDIC) and the publicly documented JLPT content scope. We do not reproduce copyrighted textbooks or past exam papers.

How explanations are written

Each guide starts from this structured data and is written to be genuinely useful — meaning, nuance, common mistakes for English speakers, and natural examples. Drafts are reviewed for Japanese accuracy and natural English before publishing, and we revise pages as we spot improvements.

How practice questions are made

Every question in our question bank is generated from our own data — we never copy real exam questions, which are copyrighted. Wrong-answer choices are drawn from genuine confusion relationships (look-alike grammar, words that share a kanji, near-synonyms) so the practice mirrors the real difficulty of the JLPT rather than offering obvious distractors.

Corrections
