A tire revolution direction determination system includes a detection device arranged in each of two tires coupled back-to-back and a monitoring unit. The detection device includes a first detector that detects a first acceleration in a tire diameter direction and a second detector that detects a second acceleration in the tire diameter direction. The first detector is arranged in front of the second detector in a reference direction. When the monitoring unit receives the first acceleration and the second acceleration from the detection device while a vehicle travels forward, it specifies change over time of the first acceleration and change over time of the second acceleration and determines whether a direction of revolution of the tire where the detection device is arranged is the reference direction based on whether change over time of the first acceleration is more advanced than change over time of the second acceleration.
