Terms & Privacy
Last updated: April 2026
DirtJapan started as a personal project. This page explains how the site works, what you can expect, and how your data is handled. Plain language, no legalese.
Disclaimer
All location information on DirtJapan is provided as-is, without any warranty of accuracy or completeness. Trail conditions, access, regulations, and hazards can change without notice. Always verify conditions independently before riding. Offroad riding carries inherent risks — you ride at your own responsibility. DirtJapan is not liable for any injury, damage, or loss that may result from using information found on this site.
User-Submitted Content
Much of the information on DirtJapan comes from community submissions. By submitting a location or other content, you grant DirtJapan permission to display, edit, and use that content on the site. DirtJapan reserves the right to edit or remove any submission at its discretion. We do our best to verify submissions, but we cannot guarantee the accuracy of user-contributed information.
Copyright & Intellectual Property
By uploading photos or other media to DirtJapan, you confirm that you own the rights to that content or have permission to share it. You grant DirtJapan a non-exclusive, royalty-free license to display, resize, and use the uploaded content on the site. DirtJapan does not claim ownership of your content — you retain all rights. If you believe any content on this site infringes your copyright, please contact us (see Takedown Requests below) and we will promptly remove it.
Third-Party Information
DirtJapan may display publicly available business information such as phone numbers, email addresses, and website URLs for riding locations, parks, and related businesses. This information is collected from publicly accessible sources or submitted by community members. If you are a business owner and would like your information corrected or removed, please contact us at contact@dirtjapan.jp and we will comply promptly.
Takedown Requests
If you believe that any content on DirtJapan infringes your rights — whether copyright, privacy, or otherwise — please email contact@dirtjapan.jp with details of the content in question and the reason for your request. We take all takedown requests seriously and will respond and remove content within a reasonable timeframe.
Privacy
DirtJapan collects only the data needed to operate the site. Here's what that means:
- Newsletter signup — your email address and language preference, used solely to send you updates about DirtJapan.
- Location submissions — the information you provide in the submission form (location details, your contact info if given), used to review and publish spots.
- Social login (Google, X/Twitter, LINE) — your profile ID and display name from the provider you sign in with, used for authentication and to associate your account with your submissions and settings. We do not access your contacts, posts, or other account data.
- Email login — your email address, used to send a one-time sign-in link. No password is stored.
- Basic analytics — anonymous page views via Vercel Analytics. No personal data is collected through analytics.
Your data is not sold, shared with third parties, or used for advertising. Data is stored on Supabase (hosted in the cloud) and handled with reasonable care.
If you have questions about your data or want it removed, email contact@dirtjapan.jp.
