PROBLEM TO BE SOLVED: To provide a floating-type breakwater that does not require underwater construction work and reduces wave energy while keeping moored stably on the sea at a set position.SOLUTION: A floating-type breakwater of the present invention floats on the sea and cancels wave energy, and includes: a buoyancy maintenance part having a floating space formed inside for maintaining buoyancy; a rotary body that rotates around a gravity center axis of the floating-type breakwater; an inclination measurement part that measures an inclination angle of the gravity center axis to a reference axis, along with angular velocity; a torque generating part that rotates the rotary body; a storage body disposed at a bottom edge of the buoyancy maintenance part for maintaining a center of gravity on the gravity center axis at the bottom edge of the floating-type breakwater, and housing the rotary body and the torque generating part; and a rotation control part that controls an intensity and direction of rotation of the torque generated by the torque generating part, based on the angle of inclination and the velocity measured by the inclination measurement part.SELECTED DRAWING: Figure 1
