We conducted another environmental education activities at Sophia Forest in Karuizawa on November 12 (Sunday). Nineteen graduate students and three faculty members joined the activities. In the co-operations with the District Forest Office and the Forest Association in the region, we learned measures to protect forest and arranged wood-made walkways, and observed the nature in the forest. It was also a great opportunity to enjoy autumn leaves in the forest. (This activity is financially supported by the Green Fund
