Kanagawa Yokohama City
The ultimate totonou experience by the station, a post-town spa with a signature mint cold bath and natural hot spring water
"Manten no Yu Natural Hot Spring" is a day-use bath facility with a post-town theme inspired by the Tokaido, located in front of Kamishin-Kawasaki Station in Yokohama, Kanagawa Prefecture. The sauna area features two types: a six-tier tower sauna where auto-löyly operates every hour and powerful waves of heat pour down, and a steam salt sauna that leaves the skin smooth. Its signature mint cold bath delivers the ultimate cooldown thanks to a refreshing menthol effect and a carefully designed purification system. The bath area offers a wide variety of tubs, including a brown natural hot spring bubbling up from deep underground, a Wakan carbonated spring blended with medicinal herbs, and a lukewarm bath. With a restaurant and relaxation services as well, it is a place where everyone from sauna beginners to seasoned sauna enthusiasts can deeply reset both body and mind.

A charming open-air area that evokes a Tokaido post town. It features a rock bath, a pot bath, and a lying-down bath filled with amber-colored natural hot spring water bubbling up from deep underground, along with a silky bath where tiny bubbles envelop the skin. While feeling the outdoor air, you can forget the bustle of the city and leisurely enjoy this famous spring.

The spacious large bath area is lined with a variety of functional tubs, including the signature Wakan carbonated spring. This Wakan carbonated spring blends carefully selected medicinal herbs with highly concentrated carbonated spring water, soothing both body and mind with its rich aroma and circulation-boosting effects. There are also daily rotating baths and a full range of jet baths, so you can enjoy a relaxing soak to match your mood of the day.

A spacious, humid dry sauna designed in a six-tier tower shape. Strong auto-löyly operates at the top of every hour, and a milder auto-löyly at 30 minutes past the hour, allowing you to feel waves of heat to suit your preference. Aufguss events by sauna masters, including the regular "Hustle Heatwave," are also held, letting you enjoy the powerful heat and deep sweating that captivate sauna fans.

A gentle steam sauna filled with billowing vapor. By gently rubbing the salt provided in the room all over your body, old dead skin and excess sebum are removed, leaving your skin soft, smooth, and moisturized after bathing. Even if you are not fond of high-temperature saunas, you can warm up slowly while relaxing.

A signature cold bath of Manten no Yu made with a proprietary blend of mint extract. Thanks to the effect of menthol, it feels crisp and refreshing beyond what the actual water temperature suggests, quickly tightening up a body warmed by the sauna. With enough depth to immerse yourself up to the shoulders and crystal-clear water treated by the same advanced purification system used at renowned sauna facilities, it promises the ultimate cooldown.
