Shizuoka Ikawa Onsen is a remote mountain thermal spring in the Ikawa area of Shizuoka City, Japan, located high in the upper Ōi River valley within the Southern Alps mountain range, accessible by the historic Ōigawa Railway whose steam locomotives make the journey as memorable as the destination itself. The bicarbonate-rich hot spring waters emerge from deep alpine rock formations and are prized for their soft, gentle mineral composition that soothes tired muscles and promotes deep relaxation after trekking in the surrounding Southern Alps wilderness. Enveloped in dense cedar and cypress forest at high altitude, this onsen offers the quintessential Japanese mountain thermal experience in one of Shizuoka Prefecture's most remote and scenically dramatic valleys.
