Nagano Yamanouchi Town
A beautifully emerald-green, free-flowing cloudy bath from the facility's own spring, and a well-water cold plunge bath with famous water
"Motoyu Hakoyama Onsen" is a hidden hot spring inn tucked away in Yamanouchi Town, Shimotakai District, Nagano Prefecture, offering day-use bathing and limiting stays to just 2 groups per day. The hot spring is a renowned bath with 100% free-flowing natural spring water from the facility's own source, which the owner drilled himself in 1999. The water is sodium-calcium chloride-sulfate hot spring water, with a pleasant iron aroma, and it is a mysterious cloudy bath that changes appearance from white or ocher to a beautiful emerald green depending on the day. The open-air bath is kept on the lukewarm side, allowing you to linger as long as you like while gazing at the majestic silhouette of Hakoyama in front of you. A genuine Finnish sauna equipped with a Metos stove installed next to the bath, and alternating hot-and-cold bathing in a cold plunge bath luxuriously filled with natural well water that is extremely smooth and pleasantly cool, provide exceptional relaxation that only a hidden hot spring can offer.
An outstanding cloudy bath with 100% free-flowing natural spring water from the facility's own source, with no added water at all, changing color from white or ocher to a very beautiful emerald green depending on the day. Rich in iron, it helps remove old dead skin cells and leaves the skin smooth, while the excellent heat-retention and moisturizing effects of its chloride spring water keep you pleasantly warm long after you get out.
A full-fledged Finnish-style dry sauna with a Metos stove, quietly standing inside a dim, atmospheric wooden bath area. The set temperature is kept high, and the gentle natural convection of heat spreading through the room softly yet firmly warms you to the core, encouraging exceptional sweating.

A luxurious free-flowing cold plunge bath located right next to the sauna room. It uses very cool, pure natural spring water from a mountain foothill well, and its smooth, mellow texture is a hallmark. The crisp, cold water gently wraps around your body after the sauna and helps you cool down refreshingly.
