"4th Japanese ultra. This was by far the hardest of the lot so far. We started from the Kigensugi bus stop from here up until 1.5 km from the top was smooth sailing, the last 1.5 to the summit were extremely steep though. However the way down was much worse. We were wanting to catch the bus from the Arakawa trailhead out, however what wasn't clear to us was that from Miyanoura down to the Jomonsugi was extremely undulating, uneven terrain. Additionally, many of the paths had turned into creeks making descending even more difficult. Once we got down to the forest railway we tried to jog the rest of the way to make it in time to catch the bus. Unfortunately, the path was so poorly signed that we couldn't tell how far we were along, and stopped jogging to conserve energy. In the end we eventually made it to the trailhead and caught a taxi back down the hill. Altogether a extremely difficult hike but enjoyable in retrospect." — Hiyouboots • Sep 6, 2025
