1. A wireless tag communication device, comprising:
a communication device configured to communicate with a wireless tag that is a target;
a position detection sensor configured to detect information indicating a self position of the wireless tag communication device;
a memory configured to store the self position, which is specified based on the information detected by the position detection sensor, in association with a reading result obtained by the communication device reading the wireless tag; and
a processor configured to estimate, using a processing method selected according to a distance between the self position, which is specified based on the information detected by the position detection sensor, and an estimated position of the wireless tag, a position of the wireless tag based on reading results obtained by reading the wireless tag at three different self positions each including the self position serving as an endpoint of the distance, the reading results being stored in the memory.
