A massage machine includes a display unit or a voice output unit and a control unit that controls functions of the massage machine. The control unit includes control modes in which the functions assigned to each of the control modes are at least partially different from each other. The control modes include a full function control mode in which all or almost all of the functions are assigned, and a function limitation control mode in which the functions are at least partially limited. When the massage machine is in a predetermined state, the control unit proceeds to the function limitation control mode. In the function limitation control mode, the control unit causes the display unit to display information relating to the massage machine, or causes the voice output unit to output the information by using a voice. The information is receivable from a service provider.
