[Object]To provide a future-image predicting device for predicting a future-image of a target person caused by a predetermined disease[Solution]A future-image predicting device 1 includes a storing unit 3, an input unit 2, and a control unit 4. The storing unit 3 stores a first database which indicates a relation between health-related data and a risk level of Metabolic syndrome, and a second data base which indicates a relation between the risk level of Metabolic syndrome and a change tendency in an appearance or an organ. Health-related data and appearance data or organ data of a target person are entered into the input unit 2. The control unit 4 determines a risk level of Metabolic syndrome for the health-related data of the target person, while referring to the first database; determines a change tendency in an appearance or an organ of the target person, based on the determined risk level, while referring to the second database; and generates a future-image of the target person in an appearance or an organ, based on the appearance data or organ data and the determined change tendency.
