- Can I freely enter the underground chamber shown in Fate/Grand Order: First Order?
- No, access is generally by advance reservation tour only through the official Ryu-Q Kan program. Entry to the famous pillar chamber may be restricted depending on weather, flood-control operations, and maintenance.
- Is photography allowed inside the Underground Temple area?
- Photography is usually allowed on regular tours for personal use, but tripods, drones, or commercial shooting may require separate permission. Always follow staff instructions because operational safety rules can change on the day.
- What should anime fans know before planning a pilgrimage to this spot?
- Check the latest tour schedule on the official facility website, because closures and special courses change seasonally. It is easiest to visit with a reservation, comfortable shoes, and extra travel time from Minami-Sakurai or Kasukabe area transport.
