An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. In a case of assisting the user in moving to turn left, the motor generates a tension larger than or equal to a first threshold in each of the second wire, the third wire, and the fourth wire at an identical timing in a swing phase of a left leg of the user, and generates a tension larger than or equal to the first threshold in each of the fifth wire, the sixth wire, and the eighth wire at an identical timing in a swing phase of a right leg of the user.
