Tokyo Hamura City
A healing retreat of natural hot springs and an authentic sauna, wrapped in Nishitama's greenery and breeze
"Freshland Nishitama Yotsuba no Yu" is a day-use bath facility in Hamura City, Tokyo. Its alkaline simple hot spring, drawn from deep underground, is gentle on the skin with a soft, soothing texture that wraps both body and mind in comfort. The newly installed authentic Finnish sauna features automatic löyly, maintaining a pleasant level of humidity that warms you gradually from the core. You can enjoy the distinct atmospheres of the "Sun Bath" and "Moon Bath," which alternate weekly, and after bathing, take a refreshing outdoor air bath in the open-air bath while overlooking Nishitama's lush greenery and sky. With a grassy lawn area and a BBQ space as well, it is a place where you can spend the day at your own pace.

A large public bath wrapped in a bright and warm atmosphere. The alkaline simple hot spring drawn from deep underground is appealing for its soft, skin-caressing texture. In the open-air bath with its sense of openness, you can spend a blissful moment soaking in the water while feeling Nishitama's rich greenery and refreshing breeze.

A large public bath with calming interior tones that soothe the mind. At night, the quiet starry sky and soft moonlight illuminate the surface of the open-air bath. Listening to the rustle of the trees and the pleasant sounds of nature, you can surrender yourself to the smooth, gentle natural hot spring and find deep peace.

A private bath where you can enjoy the water freely in a private space without worrying about other people. In the spacious, clean bathtub, families and friends can share a relaxing time together. It is also designed with barrier-free access and a universal toilet, making it a gentle, comfortable space for everyone.

A traditional Finnish-style sauna that has long been loved in Northern Europe. Water is automatically poured onto the heated sauna stones, filling the room with pleasant humidity and gentle heat. Wrapped in the scent of wood, you can enjoy a deep, gradual sweat in a space where breathing feels easy. After tightening your heated body in a refreshing cold plunge bath, head straight to the open-air area. Gently brushed by Nishitama's clear air and quiet breeze, you are led into an outdoor air bath that deeply resets both body and mind.
