"Just 90 minutes from the Jikoundani , where Japanese snow monkeys soak in their very own onsen, this ryokan’s onsen is exclusive to overnight guests and divided into three minimalist chambers, each with decreasing amounts of light. The last is nearly pitch black, except for a dramatic crack of light that creates a sensory-deprived “in utero”-style soak."
