9. A multilingual transmission system comprising: a client device that transmits a request for desired text data and that receives the desired text data; and a server device that transmits the desired text data to the client device according to the request from the client device, the server device provided at a location separate from the client device; wherein the client device includes: a requested information transmission unit for transmitting text identification information that identifies the desired text data and requested language information that designates language of the text data; and a reception output unit that receives the desired text data from the server device and outputs the desired text data; and wherein the server device includes: a requested information reception unit that receives the text identification information and the requested language information transmitted from the client device; a pivot language memory that stores pivot language data expressed in a pivot language; a text retrieval unit that retrieves pivot language data from the pivot language memory based on the text identification information, the retrieved pivot language data having a content that is different from a content of the text identification information; a target language text generator that generates, based on the pivot language data retrieved by the text retrieval unit, target language text data in the language indicated by the requested language information, wherein the target language text data differs from a translation of the text identification information; and a text transmission unit that transmits the target language text data generated by the target language text generator to the client device as the desired text data.
