A YAMAP activity log published on 11 November 2026 is labeled as a side entry for Okueyama, with Goyodake and Shinbyakushoyama also named in the activity title. The hike did not follow the planned route to the summit.
The recorded totals are 4 hours 29 minutes, 7.3 km, 724 m of ascent and 728 m of descent, including 20 minutes of rest. The course constant is given as ordinary, 17, calculated from a standard time of 4 hours 23 minutes. Average pace is mentioned, but no pace figure is given. The supplied text also lists checkpoint times without naming the points.
The plan was to go from Sanrigawara (三里河原) via the Gonshichi Hut junction (権七小屋吐合) and Nakase Matsudani (中瀬松谷), reach the summit of Okueyama (大崩山), and descend from Wakuzuka (ワク塚). The author instead decided to turn back after reaching Hakeno (吐野, read in the log as Hakeno).
Multiple forecasts had been checked: rain the day before, with clearing expected from midday on the hike day. WINDY, however, forecast rain and strong wind even before noon, and Tenkura showed strong wind at grade C. As usual, an alternative mountain route in Kumamoto had been prepared. Its forecast was better, and the course looked relatively easier to climb. The author writes that the alternative would normally have been chosen without hesitation.
That judgment wavered. With a 100 km walk among other things, it had been about 20 days since a proper mountain hike. The author says that “next time” would usually have been the conclusion, but this time “I want to go” took priority, and describes the result as embarrassing while still recording the retreat.
