One horizontal axis windmill, wherein when a wind velocity exceeds a cutout wind velocity, a yaw brake is released and all blades (4a) to (4c) are brought into a feathering state (Fig. 1A). Next, the blades (4a) to (4c) are brought into a reverse-feathering state one by one in order (Fig. 1B → C → D → E). Thereafter, all blades (4a) to (4c) are held in the reverse-feathering state until an operation mode is recovered. Through the steps above, a nacelle (2) is yaw-rotated, a rotor is disposed on the downstream side of a tower (1) in a wind direction, and the leading edges of all blades (4a) to (4c) face to the windward (Fig. 1E). In the other horizontal axis windmill, the nacelle is rotated to a prescribed angle of approximately 90 deg relative to the wind direction and held by a yaw brake, and all blades are simultaneously brought into the reverse-feathering state and the yaw brake is released. In the other horizontal-axis windmill, after all blades are brought into the feathering state, the yaw brake is released and the angle of one blade is changed from the feathering state to a flat state, and when the yaw angle of the nacelle is changed by approximately 30 deg, the one blade is returned to the feathering state.
