From the hiking trail beside the old Koshu-kaido Sasago Tunnel, near Sasago Pass on the trail toward Mt. Sasago Karigaharasuri, I encountered a cub about 50 cm long approximately 50 meters ahead of my position. The cub ran up the slope on the left side of the trail, toward the Enzan side, from Sasago Pass and disappeared. I watched the same spot for about five minutes but did not see any adult bear.
