It was in the valley on the left about 20 meters ahead, roughly 20 minutes up from the Ōtōge trailhead toward Kurodake. While I was descending, it noticed the bear bell and ran away. It didn't seem to be an aggressive individual, but please be careful.

Observed for about one second a black, rounded, quadrupedal animal about the size of a medium dog—possibly a bear cub or a wild boar—running roughly 30 meters uphill into the brush. Location: where the Onnazaka and Sawa trails merge on Mt. Takagawayama.

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.
