About & Editorial Standards

E-E-A-T credentials, data integrity sources, and authorship information.

1. Project Mission

The Japanese Transit Wiki was founded to provide international travelers, local residents, and railway enthusiasts with an intuitive, highly accessible, and technically rigorous encyclopedia of the Greater Tokyo transit system. Our mission is to demystify complex rail interchanges, deliver accurate operational statuses, and document the rich histories of individual stations.

2. Authoritative Data Sources

We maintain data integrity by compiling information from official public repositories and curated historical documents. Primary sources include:

  • Association for Open Data of Public Transportation (ODPT): Provides real-time departure schedules, line status feeds, and platform numbering details.
  • Ministry of Land, Infrastructure, Transport and Tourism (MLIT): Historical station openings, coordinates, and official company records.
  • Japanese Wikipedia: Station timelines, historical modifications, and architectural shifts parsed through automated scrapers and verified manually.

3. Editorial & Verification Standards

To ensure the reliability of all transit coordinates, transfer walking times, and platform maps, our team implements a multi-tier verification process:

  • Automated Validation: Commuter routing connections are verified programmatically against structural adjacency maps to prevent looping and disconnected transfers.
  • AI Fact-Checking Engine: Submissions are checked using a customized LLM evaluation framework (accessible via our '/fact-check' suite) to cross-reference statements with external transit documentation.
  • Manual Peer Review: Volunteer administrators verify crowd-submitted modifications (bug reports, history updates, elevator placements) in our Admin Dashboard before pushing changes to the live D1 database.

4. Authorship & Transparency

This platform is maintained by the Japanese Transit Wiki Editorial Team, a group of dedicated software engineers, urban planners, and transit historians. For queries regarding API integrations, data licensing, or editorial corrections, please use the contribution forms on the respective station pages or contact us via our crowdsourcing portals.
