There was one Asiatic black bear (Tsukinowaguma) on the stairs descending from the rest/interaction area toward the Takao direction. It appeared to be large in size.

Hachioji, Tokyo

While descending the Inariyama course during trail running, I heard a loud rustling as if an animal was pushing through the bushes on my front left. When I looked toward the sound, I saw what appeared to be a black animal—likely a bear—running away quickly within about 50 meters. Although I was wearing sunglasses, it looked about 1–1.5 meters long, so I believe it was a bear. I had been running downhill with bear bells, so I think it noticed human presence and hurriedly fled. I didn’t have time to stop and take a photo, and the location is approximate. I was measuring distance by GPS as I ran, and it was just past 2 km from the summit, but I roughly identified the spot by comparing with someone’s recorded track on YAMAP. There may still be some margin of error. I posted this because there was a sighting reported yesterday at Yakoin.
