A congestion information display system includes: a storage unit configured to store a prediction model which enables prediction of a congestion status of a facility; a prediction unit configured to predict a time when the congestion status of the facility is changed from a first congestion status to a second congestion status, based on the prediction model; and a display processing unit configured to display, on a display device, prediction information indicating that the congestion status is changed at the time predicted by the prediction unit.
