1. A vehicle log transmission device that transmits, to a vehicle log analysis server, a vehicle log including a plurality of pieces of data respectively associated with identifiers, denoted as IDs indicating a data type, the vehicle log transmission device comprising:
a hardware processor that obtains the vehicle log;
the hardware processor generating one or more divided logs by dividing the obtained vehicle log using the IDs included in the vehicle log,
existing identifier storage that stores an existing identifier list, the existing identifier list being a list of identifiers corresponding to existing divided logs generated by dividing an existing vehicle log shared between the vehicle log transmission device and the vehicle log analysis server using IDs included in the existing vehicle log, wherein
the hardware processor generates an identifier for each of the one or more divided logs, and of the generated identifiers, determines that a divided log corresponding to an identifier present in the existing identifier list is a first divided log, and determines that a divided log corresponding to an identifier not present in the existing identifier list is a second divided log; and
a vehicle-side communicator, wherein the vehicle-side communicator transmits the identifier corresponding to the first divided log to the vehicle log analysis server, and transmits the second divided log to the vehicle log analysis server.
