Mt Kurohime

Mt Kurohime (Japanese: 黒姫山), which means "the black princess," is a nihyakumeizan* peak that rises quietly in the far north of Nagano, a mountain shaped by volcanic history and the heavy snowfalls that define this region. It stands above Lake Nojiri as part of the Myoko–Togakushi volcanic arc, its broad form built from layers of lava and pyroclastic deposits that have weathered into steep forested slopes and a long, elegant summit ridge. The geology gives the mountain its characteristic shape: a sturdy base, a sharply rising flank, and a ridge that opens suddenly into wide views.

​

Snow is central to Kurohime’s character. The northern Nagano highlands receive some of the deepest snowfall in Japan, and the mountain often holds snow well into spring. In early winter, which is my favourite time to climb, the snow is present but not yet overwhelming. The forest is quiet, the air crisp, and the trail feels wonderfully atmospheric without the impenetrable deep snow of later in the season. 

​

The climb begins with a steep push through forest before you confront a large artificial lake that marks the start of the climb proper. Cedar and birch dominate the lower slopes, gradually giving way to fir and dwarf pine as you gain altitude. The trail rises steadily, sometimes sharply, until you reach the summit ridge. Lake Nojiri lies to the east a calm blue surface framed by the surrounding highlands, and around Kurohime rise the peaks of Myoko (妙高山), Takatsuma (高妻山), and the distant North Alps. 

​

Wildlife thrives here with deer in the lower forest, birds moving through the ridgeline shrubs and hardy alpine plants clinging to the volcanic soil near the summit. In early winter, animal tracks cross the snow, adding to the quiet sense of remoteness.
