A work vehicle includes: a main body having a cab; a display device provided in the cab and configured to display work assistance information to be overlaid on an actual view of a work site; a display controller configured to cause the work assistance information to be displayed on the display device; and a bucket position detector configured to detect a position of a bucket relative to the main body. The display controller is configured to cause a display position of the work assistance information on the display device to follow a movement of the bucket. The display controller is configured to change a display manner of the work assistance information on the display device based on the position detected by the bucket position detector, when the bucket is moved relative to the cab in a forward direction and a rearward direction.
