A center of gravity shifting training system includes a display device having a display screen, a measurement device configured to measure a center of gravity position of the user, and a control device. The control device has a training mode and a setting mode of preparing setting data indicating a position of the target image in the display screen. In the setting mode, the control device performs estimation of a deviation of the center of gravity position based on the center of gravity position measured, and prepares the setting data indicating the position of the target image according to a result of the estimation. In the training mode, the control device displays the operation image on the screen in accordance with the center of gravity position measured, and displays the target image on the screen based on the setting data prepared through the setting mode.
