Hirose Onsen

Hirose Onsen—the Wide Rapids Spring—takes its name from a river feature of dynamic, fast-moving water spreading across a broad channel, the hirose (wide swift) evocating the sound and energy of river water moving with purposeful speed across the volcanic rock of Tochigi Prefecture's highland river systems. Tochigi Prefecture's volcanic landscape, shaped by the Nikko volcanic complex and the Nasu highland volcanic chain, produces springs of considerable thermal and geological diversity across its many river gorges and highland valleys, and Hirose's rapid-water name connects the spring to the kinetic energy of the mountain rivers that drain this volcanic terrain. The wide rapids imagery suggests a spring of flowing abundance and vigorous thermal character, its mineral waters moving with the same purposeful energy as the river feature that gives the spring its evocative name.
