An object of the present invention is to provide a communication method, a transceiver, a relay, a communication system, and a program capable of performing high-speed communication even in a case where there is an obstacle between two separated points in water. In this communication method, two points each confirm the other's position by using sound wave communication which is likely to be diffracted as a wave due to a relatively small frequency and a large wavelength. Since the communication method uses optical wireless communication in which straightness is high but high-speed communication is possible, a path for communication while avoiding an obstacle via a relay is calculated. In the communication method, the relay is guided and moved to an appropriate place according to the calculated path, and a signal is transmitted and received by using optical wireless communication using the relay that has moved to an appropriate place.
