Nirasaki, in northern Yamanashi Prefecture at the northern end of the Kofu basin, is the gateway community to the Minami Alps — the Southern Japanese Alps — whose granite peaks include Mount Kita, Japan's second-highest mountain at 3,193 metres, and the challenging wilderness ridges of the Akaishi range that attract serious alpinists from across Japan each summer. Minami Alps Onsen Nirasaki draws on sodium and bicarbonate thermal waters from the geothermal resources of the Fossa Magna geological zone where the Japanese Alps thrust powerfully from the earth, offering restorative baths for mountaineers descending from the high alpine wilderness of the Koma-ga-take and Hoji-ridge mountain circuits. The Minami Alps National Park trailhead access, the legendary crystal mineral deposits of the Yamanashi mountain zone, and the fruit orchards of the Nirasaki valley producing famous Fuji apples and Koshu grapes create a richly varied gateway experience for alpinist thermal spa visitors in northern Yamanashi.
