  ABSTRACT: We evaluated the climate change in Wakkanai area, which is located at most northern part and typically rural area in Japan. Climate parameters i.e. atmospheric pressure, air temperature, humidity, velocity, daylight hours and snow fall were obtained from Japan Meteorological Agency. Positive changes in parameters in air temperature, especially mean of the lowest air temperature (r = 0.508, p
