An information processing apparatus includes a memory, a receiver, and circuitry. The memory stores, for each one of a plurality of character strings, display number information indicating a total number of times the character string has been displayed at a user terminal, the user terminal being operated by a user. The receiver receives, from the user terminal, information on one of the plurality of character strings that is displayed at the user terminal. The circuitry updates the display number information for the displayed character string, based on the information on the displayed character string that is received by the receiver, determines whether the displayed character string is to be translated, based on the updated display number information, and sends a request to manually translate the displayed character string, based on determination indicating that the displayed character string is to be translated.
