It looked like a large dog crossed the area, but there was no owner, and I realized it was a wild animal. It was not a boar, deer, or badger. Judging from the size, gait, and silhouette, I think it may have been a young Asiatic black bear (Ursus thibetanus), so I am reporting it. Also, while walking nearby I found a black, glossy, flattened droppings. After examining it, I believe it is likely from a bear.

I was riding a motorcycle on a tour, and it was just at the spot where the guardrail goes into the mountain, so I didn't take any photos and the location is not exact. I was heading west and report an approximate location based on my memory that it was a left-hand curve a little past the Megane Bridge parking area, at a place with a white guardrail.
