Natural hot spring and an authentic Finnish sauna surrounded by the greenery of Nishitama
Tokyo Hamura City
"Freshland Nishitama Yotsuba no Yu" is a public bathing facility in Hamura City that underwent a major renovation in February 2026. Its natural hot spring, gushing up from 1,800 m underground, is known for its gentle, soft feel on the skin. The authentic Finnish sauna newly introduced as part of the renovation features auto löyly, allowing guests to enjoy pleasant heat and humidity. The differently styled "Hino Yu" and "Tsuki no Yu" alternate weekly between men and women, and a cooling outdoor bath in the open air while overlooking the lush greenery of Nishitama deeply soothes both body and mind. With an added BBQ space and gymnasium, it has further evolved into a place of relaxation for the local community.
