Abstract: In an object management system, a distributed ledger stores a real identifier, which is an identifier for identifying a real object, and a virtual identifier, which is an identifier for identifying a virtual object in a virtual space corresponding to the real object in the real space, in association with each other. Each of the plurality of nodes includes: an information receiving part that receives an identifier for identifying an object and change information about a state change including an operation of the object; an identifier acquisition part that acquires a correspondence identifier which is an identifier of an object corresponding to the identifier, by referencing the distributed ledger; an instruction information generator that generates instruction information for operating the object identified by the correspondence identifier on the basis of the change information; and an instruction information transmitter that transmits the instruction information to the corresponding object.
