The present invention relates to a separately washable rice germination apparatus which has a motor as a power source enabling the continuous circulation of circulating water for supplying moisture needed to germinate rice germs and an impeller rotated by the rotation of the motor, the motor and the impeller being detachably coupled to each other by means of a magnet force, such that scales or foreign substances accumulated in a water tank and the impeller during rice germination can be easily removed therefrom, and that separates a section where circulating water is sucked from a section where the sucked circulating water is pushed upwardly to a germination container, such that the circulation efficiency of the circulating water can be improved.
