An anomaly detection system according to the present disclosure includes: an optical fiber (10) configured to detect a state of a metal wire (20) affected by a magnetic force generated between a vehicle (60) and a guideway (50) of a magnetically levitated train; a reception unit (30) configured to receive, from the optical fiber (10), an optical signal including information indicating an effect of the magnetic force received by the metal wire (20); and a detection unit (42) configured to detect an anomaly of the vehicle (60) or the guideway (50) based on the information indicating the effect of the magnetic force received by the metal wire (20), the information being included in the optical signal.
