The field test of a small size wind turbine system has been performed in Kanagi, Aomori Pref. The wind characteristics, such as wind speed, wind direction, air temperature and output power of the wind turbine system have been recorded every ten minutes over three years. By the recorded wind characteristics and output power it was clarified that the both of mean wind speed and total output power in a month show large values in winter and small ones in summer. And it was found that the mean wind speed was around 3.2m/s at 2.5m above the ground and the utilization rate was 14 - 16% even in winter. Thus, the wind speed is not enough for the wind power generation by the small type of wind turbine system. So, it is seemed that the equipment to increase the entering wind speed to the wind turbine should be used together. On the other hand, the wind direction was limited throughout the year, and it is suitable for the wind power generation. The noise level from the wind turbine was around 50dB.
