100% natural hot spring black water and a Hokutolite bath. Exceptional relaxation in a cold plunge bath with flowing spring water
"Washinoyu" is a bathing facility in Kanagawa Ward, Yokohama City, Kanagawa Prefecture, that boasts natural hot spring water gushing from approximately 200 meters underground. Two large baths with different atmospheres, "Noten-no-Yu" and "Shinrin-no-Yu," are available on alternating days for men and women. Its biggest highlight is the 100% natural hot spring black water source, passed through Hokutolite from Akita Prefecture's Tamagawa Onsen. It also offers a "high-concentration carbonated spring" that blends this black water with highly concentrated carbon dioxide, strongly supporting beautiful skin and overall health. The sauna is a genuine dry type with excellent perspiration, and the cold plunge bath luxuriously uses the black water source as flowing water straight from the spring. This smooth cool-down experience, wrapped in the components of the hot spring, is truly worthy of being called a "town bathhouse for therapeutic bathing."
A brownish natural hot spring gushing from approximately 200 meters underground. Offered as Hokutolite Bath, passed through rare Hokutolite, it is rich in mineral components that help smooth and soften the skin. There is also a bath that blends it with highly concentrated carbon dioxide, allowing you to enjoy the spring's mineral benefits and the circulation-boosting effects of carbonation at the same time for a luxurious bathing experience.
A genuine dry sauna with excellent perspiration, where you can fully feel the heat. The softly lit room offers the perfect space to quietly sweat while facing yourself. Just outside the sauna room is the facility's signature cold plunge bath with flowing spring water, allowing for a smooth and powerful hot and cold contrast bath.
