"Mochizuki Ryokan, Kikuchi Onsen" is a hot spring inn in Kikuchi City, Kumamoto Prefecture, offering free-flowing natural spring water straight from the source. It prides itself on an abundant flow drawn from the blessings of Mount Aso and the Kikuchi Gorge, and on its "completely natural hot spring," with no added water, no heating, and no circulation. The colorless, clear, silky bathwater is also known as the "beauty bath," and is said to have excellent skin-beautifying effects. The garden open-air bath also features a cascading bath, letting guests spend a deeply soothing time surrounded by the sounds of nature. Special rooms include guest rooms with their own free-flowing natural hot spring bath, allowing you to enjoy the famous water in a private setting. The all-japanese-style rooms built entirely of cypress, together with cuisine made from seasonal ingredients carefully selected by the proprietress, who loves fishing, promise a serene and atmospheric day of relaxation.
