Mt Kazafuki 

Mt Kazafuki (Japanese: 風吹岳) sits in Otari on the quiet northern edge of Nagano, a gentle but atmospheric mountain whose broad ridges and high wetlands give it a character distinct from the sharper peaks of the North Alps. Its topography is shaped by the old Kazafuki volcanic system, producing long forested slopes, rounded highlands, and a summit wrapped in trees rather than exposed rock. What makes the mountain special is not a dramatic peak but the landscape around it, in particular Kazafuki‑Ōike, a large high‑elevation pond surrounded by marshland and small satellite pools. This wetland basin, set in a shallow volcanic depression, creates one of the most unusual alpine environments in northern Nagano.

The hike itself is steady and rewarding, although access to the trailhead is difficult and time consuming. Most hikers including me begin from the Kitano trailhead, climbing through quiet forest before emerging onto the open highlands near the pond. The ascent is not technical or dangerous, but it is long and can feel demanding due to sustained steep sections and occasional muddy stretches, especially after rain. Trails are generally well maintained, although you should beware of slippery wooden walkways and wet ground near the wetlands. Hikers should also be aware that this is bear country. The summit of Mt Kazafuki is modest and forested, with limited views, but the journey is defined by the approach: the gradual transition from deep forest to open marsh and the stillness of Kazafuki‑Ōike. From the trail you can look south to Mt Shirouma (白馬岳) and other North Alps mountains.
