Oku no Yu

Oku no Yu (奥の湯) is a long-standing hot spring retreat in Kurokawa Onsen, known for its wide range of gender-separated baths that cater to various preferences. Guests can enjoy features such as a misty steam sauna, an atmospheric cave bath, and several open-air pools overlooking a scenic mountain river. These outdoor baths provide a chance to unwind while listening to the gentle flow of water and soaking in the natural beauty of the surrounding forest. The setting is tranquil and rejuvenating, offering a soothing escape from everyday life.

While the facilities may lack the polished aesthetics of more upscale onsen, Oku no Yu compensates with its variety, rustic charm, and affordability. The range of bathing options makes it especially attractive for those who enjoy sampling different styles in one location. Its laid-back atmosphere and scenic riverside setting continue to attract both first-time visitors and seasoned onsen enthusiasts seeking a peaceful, no-frills experience in nature.
