Mount Kuroiwa

黒岩山

Iiyama, Nagano · Elevation 911 m

Mount Kuroiwa is a peak of about 911 metres on the Sekida mountain range, straddling the boundary between Iiyama City (Nagano) and Myoko City (Niigata). It is a highlight of Section 3 of the Shin'etsu Trail, Japan's first long-distance hiking trail. The entire mountain is designated a National Natural Monument as a rare habitat where both Luehdorfia japonica and L. puziloi inexpecta butterflies coexist. Alpine ponds, ruins of Sengoku-era Kuroiwa Castle, and a small shelter overlooking the Iiyama basin are scattered along the trail.
