AT A GLANCE
Why go?
Kurobane Onsen Goho-no-Yu is a bright, easy-going municipal day-spa on the quiet edge of Otawara in northern Tochigi. It takes its name—'Five Peaks Bath'—from the sweep of mountains you can gaze at while you soak: Nasudake, Osabi, Takahara, Nyoho and Nantai, ranges that frame both the Nasu highlands and the Nikko peaks.↗↗↗
The draw is the water itself. This is a colourless, odourless alkaline simple spring, the kind the Japanese call a 'beauty water' because its slippery, soap-like feel leaves skin silky-smooth. With an open-air bath, indoor baths, a sauna, a rural restaurant, a free foot bath and a vast tatami rest room, all for around 500 yen for an adult, it is one of the best-value ways to while away an afternoon in Tochigi.↗↗↗
A 'Beauty Water' Worth Travelling For
The heart of Goho-no-Yu is its hot spring, drawn from Kurobane Onsen. Officially classed as an alkaline simple spring, the water runs clear, scent-free and gentle on the skin. Alkaline springs of this type have a characteristic slick, almost soapy feel—an effect that softly exfoliates and leaves bathers remarking how smooth their skin feels afterward. The city describes it as a classic 'beauty water', and many return for that very sensation rather than for any dramatic colour or sulphur smell.
