A communication management system relays communication between a first communication terminal that transmits data of a spherical image and a plurality of second communication terminals. The communication management system includes a memory and circuitry. The memory stores session identification information in association with addresses of communication terminals participating in the video communication session. The circuitry receives, from the first communication terminal, particular session identification information identifying a particular video communication session, and a display control parameter for limiting a display area of the spherical image to be displayed by each of the plurality of second communication terminals in the particular video communication session to a part of an entire area of the spherical image. The circuitry transmits the display control parameter to each of the addresses stored in the memory in association with the particular session identification information other than an address of the first communication terminal.
