Komi, Nagano

At Shirakoma-no-ike, the water sits so high on the flank of the Kita-Yatsugatake that the surrounding forest is draped in moss rather than undergrowth. The lake itself is small and dark, and the air above it carries the cold of elevation even in the warmer months. Koumi-machi occupies the corridor between the Yatsugatake range and the Oku-Chichibu massif, the Chikuma River threading through its floor while the land climbs steeply on both sides, from valley settlements to ridgelines well above the treeline.

The Koumi Line passes through on its slow arc through the highlands, stopping at Matsubara-ko Station and Koumi Station before continuing on. At Koumi Station, a small station building and shopping center called Aruru opened in the late 1980s — a modest pivot toward convenience in a landscape that otherwise resists it. Inagoyu Onsen, developed in the Meiji period, sits at around fifteen hundred meters and functions as a trailhead inn for Kita-Yatsugatake climbers; its cold mineral spring is drinkable, and a single mountain-lodge-style ryokan still operates there. Matsubara-ko, a cluster of three connected lakes near the valley floor, freezes in winter and becomes a skating surface.

The Koumi-machi Kogen Bijutsukan, designed by Ando Tadao and opened in the late 1990s, uses the panorama of Kita-Yatsugatake as part of its spatial logic — the mountain is not backdrop but participant. The town's library, housed in the Kitamaki Rakushu-kan community center, runs a mobile lending service into the surrounding settlements. These are the quiet infrastructures of a place that has organized itself around elevation, water, and the long rhythm of mountain seasons.
