While descending the Inariyama course, I witnessed a black shape moving down the slope ahead. It was some distance away, so I cannot be certain.

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.

At approximately 5:10 a.m. on May 31, 2026, near the Otstuden Falls area within Hachioji Castle Ruins in Motohachiōji 3-chome, Hachioji City, there was a report of a bear growling. Since a bear was also sighted at the same location yesterday, please refrain from going out in the vicinity, and if you see a bear, call 110 from a safe location.

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.

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.

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.
