About Kohoku Natural Hot Spring Yuttari COco
"Kohoku Natural Hot Spring Yuttari COco" is a spacious day-use onsen facility located inside a large commercial complex in Tsuzuki Ward, Yokohama City, Kanagawa Prefecture. Its greatest appeal is the chance to enjoy a brownish natural hot spring rich in salt, gushing from 1,503 m underground, and offered as a free-flowing source bath. The sauna is a Finnish-style sauna equipped with automatic löyly, where powerful waves of heat envelop the entire body. Especially noteworthy is the impressive cold-plunge selection, featuring two types: an extra-cold indoor bath with a depth of 110 cm, and an open-air milky cold plunge bath with fine bubbles that feel pleasantly soft. There is also a vast rest area with 30,000 manga volumes and Yogi Bo furniture, making it an urban oasis where you can spend the whole day in complete relaxation.
