An information processing terminal: stores a counterpart list of one or more counterpart identifiers each representing a communication counterpart candidate of the information processing terminal; accepts a request destination identifier representing a counterpart information processing terminal, and participation authentication information; determines whether the request destination identifier matches any one of the counterpart identifiers; generates one of first communication start request information and second start request information, each request including the request destination identifier, the participation authentication information, and a request for communicating with the counterpart information processing terminal; and transmits the communication start request information to the communication management apparatus. When the request destination identifier matches the counterpart identifier, the circuitry generates the first start request information addressed to the communication management apparatus. When the request destination identifier does not match the counterpart identifier, the circuitry generates the second start request information addressed to the counterpart information processing terminal.
