Okuwa Onma Onsen
A rare moru onsen rich in plant-based organic matter, seen only in limited places across Japan. Its dark coffee-like color is its hallmark, and ingredients such as humic acid help remove dead skin cells and leave the skin smooth. Because it contains many natural moisturizing components, its appeal lies in the moisture-like sensation it gives, almost like lotion. You can enjoy this luxurious water not only in the indoor bath, but also in the outdoor rock bath and tsubo-yu, and feel how well it warms you, helping prevent you from getting chilled after bathing.
