Bathe in a mineral rich onsen in a national park
This secluded hot spring in Joshin'etsukogen National Park is surrounded by nature. It has three public baths but Hoshi no Yu is its best known and most beautiful. It is over a century old and is fed by a spring that bubbles up from between stones laid underneath.
Take a dip in its wooden baths to benefit from its steamy, mineral-rich waters known for their high calcium and sodium sulfate content. Both gender-segregated and mixed bathing is available.
Drop in for the day or enjoy this remote spot's tranquility a little longer with a stay in one of its traditional Japanese rooms.
