An information service apparatus provides information described in a language suitable for a user. The information service apparatus has an operation panel on which operation information on the information service apparatus is displayed: It is judged whether or not information can be provided in a language designated by discrimination information contained in a request from a terminal. When it is determined that the information in the language designated by the discrimination information cannot be provided, an operation panel language used for displaying the operation information on the operation panel is set as the language used for providing the information.
