MenkyoQuest (menkyoquest.com) is a free web app for practicing the Japanese driving license written test. This page describes our purpose, the editorial process behind our questions and explanations, the team operating the site, and the relevant disclaimers.
1. Purpose
We give people preparing for the Japanese driving license written test (provisional and full license) a free, ad-light environment to practice as many times as they need.
All 510 questions are sourced from the National Police Agency's official Rules of the Road, and our chapter structure mirrors that rulebook. Each question carries a source_reference pointing back to the exact section, accessible from the explanation modal after each answer.
2. Source — Rules of the Road (National Police Agency)
Every question is based on the National Police Agency's Rules of the Road, published as a notification of the National Public Safety Commission. Under Article 13(2) of the Japanese Copyright Act, the Rules of the Road are public notifications and are not subject to copyright, so quoting and adapting them into practice questions is permitted.
When the rules are amended, we update the affected questions first. The last-updated date appears at the top of this page and in the metadata of each chapter page.
- Source: Rules of the Road (National Public Safety Commission notification)
- Chapter structure: matches the 11 chapters of the rulebook
- Total questions: 510 (true / false + multiple choice)
3. How AI fits into our explanations
Explanations are produced with a human-in-the-loop pipeline: editorial team members read the rulebook, draft prompts for Claude (Anthropic), review what the model writes, and ship only after manual correction. We never publish raw model output.
In detail:
- Extract articles and sections from the official PDF into structured JSON (in-house tooling)
- Generate true/false and multiple-choice draft questions per section with Claude
- Have Claude draft each explanation, citing the corresponding section of the rulebook
- Read every one of the 510 questions ourselves, fixing errors and ambiguity
- For the English version under
/en, translate with Claude and review key terminology (provisional vs. full license, jokō, etc.) for consistency
AI output is fallible. If you spot a typo, mistranslation, or an unclear explanation, please email us — we'll fix it quickly.
