A YAMAP activity log published on 10 November 2026 records a short outing on Sakadoyama (坂戸山), titled “坂戸山113 雨の紅葉🍁-Sakadoyama.”
The log lists 3.1 km in 1 hour 5 minutes with no rest. Ascent was 452 m and descent 459 m. It gives a standard time of 2 hours 26 minutes for the course-constant calculation and marks the route “easy” (やさしい), with the figure 10 shown with that rating. The recorded window runs from 08:03 to 09:09. An average pace is mentioned in the activity header, but no pace figure is given.
The writer was off work on paid leave. A roadside thermometer read 7°C. The forecast was cloudy, with only about 0.1–0.2 mm of rain per hour. Morning rain led them to start in a raincoat, as usual. They wrote that, in that weather, only two people were at the “slide” (スライド); the log does not explain the word.
Autumn leaves were at their best, with fall already underway and the season feeling at its peak. Ongoing rain had brought out the scent of takanotsume (タカノツメ). The route that day was from Momonokidaira (桃ノ木平) to Jōsaka (城坂), where the foliage was described as excellent.
After returning, the writer changed tires in light rain. They expected temperatures to rise again from the next day. In the afternoon they went to a talk in Minamiuonuma City titled “お酒と健康を考える講演会” (a lecture on alcohol and health).
