Mount Kinpu (Kinpugazan), at 2,599 m, is one of the principal peaks of the Oku-Chichibu mountains along the border of Yamanashi and Nagano, reached from the Yamanashi side via the Zenzatoge trailhead near Masutomi in Hokuto City. No permit is required. The approximately 10 km round trip climbs roughly 750 m through subalpine conifer forest before opening onto exposed granite slabs and boulder fields in the final approach to the summit, where a distinctive freestanding granite pillar known as the Goshintai marks the top and serves as an object of mountain worship. The trail is well-marked but includes sections of rock scrambling and loose scree near the summit ridge that demand sure footing and basic route-finding; there is no technical climbing gear needed, but the terrain is more demanding than a standard forest trail. Weather on the exposed upper slopes can change quickly, with wind and cloud building by early afternoon even in clear conditions. There is no water source above the lower forest, and no mountain hut directly on this route, so hikers carry all supplies for the day. On clear days, the summit gives sweeping views toward Mount Fuji, the Southern Alps, and the Yatsugatake range. The trail is realistically hikeable from late April through November, with snow occasionally lingering into May on the shaded upper sections.
