Kirigamine Highlands

Kirigamine is a broad, gently rolling highland plateau rising above Lake Suwa in central Nagano, a landscape of open grassland, marsh and wildflower meadow quite unlike the forested mountains that surround it. At around 1,600 to 1,900 metres, its treeless, wind-swept ridges offer some of the most expansive panoramic views in the region, and in high summer its slopes erupt into colour, making it one of the most rewarding easy-walking destinations in the Japanese highlands.

The plateau's signature spectacle comes in mid-July, when the grasslands of the Kurumayama area turn a brilliant yellow with the bloom of the nikko-kisuge, a native daylily. Vast drifts of the flowers cover the hillsides, and gentle trails and boardwalks let visitors walk right through the display; on a clear day the yellow meadows roll away toward distant blue ranges under a huge sky. Other seasons bring their own flora, from spring and early-summer alpine blooms to the russet grasses and clear air of autumn, when the plateau glows in warm tones and the views are at their sharpest.

Those views are a large part of Kirigamine's appeal. From the high points, especially the summit of Kurumayama, reached by a chairlift or a short walk, a full 360-degree panorama opens up: Mount Fuji rising beyond nearer ridges to the southeast, the Southern, Central and Northern Japan Alps ranged around the horizon, and Lake Suwa glinting in the basin below. The Kirigamine marsh, a protected wetland threaded with wooden walkways, adds ecological interest and a network of easy, well-signed trails links the various high points, so walkers can tailor a route from a short stroll to a half-day traverse across the open tops.

Kirigamine lies along the Venus Line, one of Japan's most celebrated scenic driving roads, which winds across the highlands linking a string of plateaus and viewpoints. This makes the area popular with drivers and motorcyclists, and the combination of sweeping roads, cool summer air and big-sky scenery gives it a relaxed, holiday atmosphere. Because the terrain is open and the main trails are gentle, it is well suited to families and casual walkers who want high-mountain views without a demanding climb, though the exposed ridges mean weather can change quickly and a windproof layer is wise even in summer.

The plateau is easily combined with the cultural attractions around Lake Suwa, including the ancient Suwa Taisha shrines, so a day here can pair grand natural scenery with historic interest. Access is via Kami-Suwa on the JR Chuo Line, from where seasonal buses climb up to Kurumayama Kogen and Kirigamine in around an hour; drivers reach it along the Venus Line from Suwa or Chino. Whether you come for the golden daylily meadows of July, the autumn grasses or simply the vast views, Kirigamine offers a breath of open highland air that feels a world away from the valleys below.
