Near the end of the descent on the Kamosawa route, about 10 minutes before the trail reaches the point where the road on the left becomes visible, a bear was found on the left side of the trail. Its body length was about 1.5 m. It appeared to be eating something from the ground; it made eye contact but was undisturbed and continued eating, and did not approach us.
