The picture is part of the video I recorded less than five minutes away from the sighting. A medium size (young adult) bear was coming down the hill to the left, about 200 meters up ahead from where I was. It got startled by my presence and ran up the hill. It was on the first part of the nakasendo trail where you enter the woods right after you cross the Yo river (heading to Nojiri from Nagiso) .

It might have been a Japanese serow, but there was an animal with four legs and one head. Its snout was shorter than a wild boar’s and its legs were long. It walked differently from a dog; the part equivalent to the shoe on a human is shaped more like a human’s. With all four legs on the ground, its body length reached from a person’s buttocks to their waist. Its tail was not visible to the naked eye.
