Editorial Policy

How content on NihongoDoya is created, checked, and kept independent

Last updated: July 16, 2026

At NihongoDoya, our mission is to give learners clear, accurate, and genuinely useful Japanese-language study materials. All educational content across this platform is produced and maintained by the NihongoDoya Editorial Team — an independent group of Japanese-language educators, curriculum researchers, and web developers. This policy explains how our content is created, how it is verified against lexical references, how it is kept independent from commercial influence, and how readers can report corrections.

1. Who Writes Our Content & How

Every grammar note, vocabulary list, example sentence and study guide on this site is prepared in-house by our editorial team. We do not republish copyrighted textbook material; the example sentences, reading passages and explanations are original and crafted specifically for this site. Our workflow is:

  • Plan — each topic is mapped to the standard JLPT (N5–N1) and CEFR (A1–B1) progression so lessons build logically.
  • Draft — the explanation, original examples and practice are drafted, with full furigana readings on kanji.
  • Reference-check — readings and meanings are verified against authoritative open dictionary data (such as the KANJIDIC2 and JMdict projects) and multiple standard grammar references.
  • Review & publish — the draft is set aside, then proofread again for accuracy and clarity before the page goes live.

2. Accuracy & Natural Nuance

Japanese grammar and vocabulary are highly contextual, so we aim to explain meaning rather than offer literal word-for-word translations. Our grammar items detail:

  • Clear formation rules and structure guidelines.
  • Practical context — explaining why and when a pattern is used.
  • The distinction between polite (です/ます) and casual (plain) speech registers.

3. Use of AI & Transparency

We believe in being open about how the materials on this site are made. Modern AI-assisted tools are part of the workflow — they help with drafting, formatting, cross-checking large data sets, and rendering clean study cards. Every published explanation, example, and translation is reviewed and verified against authoritative dictionary references by our editorial team before going live. Any data sourced from open dictionaries is credited on the relevant pages.

4. Corrections & Updates

We value transparency and continuous improvement. Despite careful review, an occasional typo or unclear explanation may slip through. If a reader reports an issue through our contact channels:

  • The report is logged and checked against reference dictionaries and standard curricula.
  • If a correction is needed, we aim to update the affected page promptly, typically within a few days.
  • Significant corrections are made openly rather than hidden, so the material stays consistent and trustworthy.

5. Editorial Independence & Advertising

NihongoDoya is independently run and supported by optional advertising. Advertisers and retailers have no control over lessons, vocabulary definitions, mock questions, reviews or recommendations. We do not publish paid editorial opinions or change educational conclusions in exchange for payment.

6. Editorial Contact
