Gateway to south Yatsugatake
Mt Amigasa (Japanese: 編笠山) is one of the most approachable peaks in the southern Yatsugatake range, yet it retains a distinctly alpine character. Straddling the borders of Nagano and Yamanashi prefectures, I often climb it from the Kannondaira trailhead, where the journey begins beneath a dense forest canopy. The lower slopes are peaceful, mossy and shaded, and the steady climb through the forest provides a gradual introduction to the rugged landscape that lies above. Another approach I've used is from the golf course on the Nagano side via Mt Nishi (西岳).
As the trail gains elevation, the character of the mountain changes. The woodland walk becomes steep and involves scrambling over moss-covered rocks, demanding a greater effort from hikers as they approach the summit. The forest gradually thins, revealing expansive views of the surrounding peaks and the distant valleys below through breaks in the trees. On a clear day Mt Fuji (富士山) can be seen through breaks in the trees.
One of the defining features of Amigasa is the extensive rockfields that cover its upper reaches. Large boulders and broken volcanic stones blanket the mountainside. I enjoy crossing these rocky sections, but they require careful footing, particularly in wet conditions. This would be a terrible place to lose your car keys. While the boulders add challenge to the climb, they stand out as my favourite part of the hike.
The broad summit rewards hikers with magnificent panoramic views. To the north, the higher peaks of Yatsugatake rise in a dramatic ridge, while the South Alps and other peaks can be seen on clear days. Mt Amigasa can be combined as part of a longer hike to Mt Gongen.
