A terminal 104 that can appropriately control an operation mode of the terminal regardless of presence/absence of a user operation includes: a storage 206 storing a mode identifier for identifying a manner mode or a normal mode; a communication device 210; a position obtaining device 208 obtaining a current position; an input device 204 allowing the user to designate the operation mode; and a control unit 200 for transmitting a mode change instruction including the current position and the mode identifier through the communication device 210, when the operation mode is designated. The terminal 104 further includes: a sound output device 214; and a processing unit, responsive to reception of a mode change instruction from other terminal, for determining whether the mode identifier included in the mode change instruction is to be stored in the storage 206, in accordance with a distance between the current position obtained by position obtaining device 208 and the current position included in the mode change instruction.
