A mixed reality space sharing system is provided with which 3D information regarding a target real space can be shared between a plurality of MR terminals while keeping the information updated, without spending a long processing time. A shared information management server includes an information management unit for creating a room by associating, with each other, 3D information and anchor information that are transmitted from a first terminal, which is at least one of a plurality of mixed reality terminals, and managing the 3D information, and a sharing unit for transmitting the 3D information and the anchor information to a second terminal different from the first terminal. The second terminal downloads the 3D information and the anchor information transmitted from the shared information management server and creates a mixed reality space using the downloaded information.
