Sources and their roles

• Names, addresses, hours, prices — official sites and social feeds first, then multiple map/booking services, then field checks. Conflicts between official and third-party data are recorded as conflicts, not silently resolved.
• Ratings — dated snapshots (value, count, check date) from Tabelog, Google Maps, Gurunavi and Jalan. Absence from any one platform is never a penalty.
• Michelin — distinction, year and official link only; no copied text or photos.
• Social & local media — buzz indicators only; local outlets (the Ishigaki tourism association and the local Yaeyama press) are summarised and linked, never reproduced.

Collection policy

• We respect robots.txt and terms of service; sources with unclear terms default to no automated fetching.
• No CAPTCHA circumvention, no login bypassing, no aggressive crawling.
• No automated scraping of Google Maps or Tripadvisor — ratings are research snapshots taken by humans/AI.
• No bulk storage of review texts, no reposting of other sites' photos or copy.

Attribution

• Maps: © OpenStreetMap contributors (ODbL)
• Michelin, Google, Tripadvisor and other names are trademarks of their owners; we are affiliated with none of them.

Photography

We currently publish no venue photos, because we do not repost images from Google, Michelin, Instagram or other sites. Photos will be added only from J-Catalyst's own shoots, venue-provided material, or properly licensed sources — each with tracked provenance.
