Kanagawa Kawasaki City
A new-style urban sauna where five saunas and four cold plunge baths intersect
"saunahouse" is an urban sauna facility in Kawasaki City, Kanagawa Prefecture. It features five saunas and four cold plunge baths with different levels of chill, all intricately designed down to the structure, lighting, and music, letting you enjoy an endless range of hot-and-cold experiences to suit your mood each day. It uses high-quality groundwater drawn from deep underground, and is fully equipped with a pool deep enough to submerge your head as well as a comfortable outdoor-air bath area. In a spacious, gender-equal facility, you can unwind after your sauna session at a restaurant with a wide variety of menu items.

A large communal bath with spacious hot tubs offering a soft bathing feel, using groundwater. The pleasant jets gently work out tension throughout the body, making it ideal for long soaking sessions before or after the sauna and during relaxation time. The jet stimulation and warm water bring deep relaxation.

A sauna with striking line lighting, designed to help calm both mind and body. The temperature, humidity, and music are all just right for relaxation, making it ideal for acclimating your body during the first set. In addition to regular auto-löyly, programs such as aufguss are held frequently, surrounding you in pleasant heat.

A new-style steam sauna that lets all five senses play. It features a unique setup where rain periodically falls from the ceiling, and fresh air and aroma are supplied along with the steam. You can refresh yourself while being enveloped in rich fragrance without feeling stifled.

A three-dimensional sauna with varying levels, like an adult jungle gym. A forced-air supply system keeps fresh air circulating at all times, creating a comfortable environment where it is less likely to feel hard to breathe. It has a unique program that steams dry oak to control humidity, so you can enjoy pleasant heat with friends.

The hottest, most aggressive sauna, with heat enhanced through both sight and sound. Fiery red lighting reminiscent of magma is paired with techno-rock sounds, creating a deep sense of immersion that goes beyond simple relaxation. After pushing yourself to the limit, the route to the extremely cold cold plunge bath is highly recommended.

A quiet sauna that makes lavish use of kelo, the "wood jewel" imported from Finland. By applying the kelo wood in rib-like strips, it increases radiant heat and creates a richer thermal experience. Conversation is kept to a minimum except for calling out löyly, so you can enjoy self-löyly at your own pace while savoring the natural aroma and stillness.

A cold plunge bath using high-quality groundwater that springs from deep underground. Its mild temperature setting makes it comfortable even for those who do not like extremely cold cold plunge baths, and you can sit back, stretch out your legs, and gently cool down your overheated body.

The coldest cold plunge bath in the facility. Using groundwater, it is known for its intense chill that quickly tightens a body warmed to the limit in the sauna. After immersing yourself up to your shoulders, a blissful route awaits: seats in the mist area, outdoor-air bathing on the veranda, or cold-cold bathing in the pool.

A spacious pool located in the center of the main floor. Filled with high-quality groundwater, it is possible to swim or submerge yourself. Since you can cool down all the way to your head, it further enhances the relaxing effects after the sauna.

A high-concentration carbonated spring where fine fizzy bubbles envelop your entire body. Depending on the season, the temperature may drop below 30°C, allowing it to be used like a cold bath as the finishing touch to cold-cold bathing. You can enjoy a unique cold-cold-cold bathing experience by moving from the extremely cold cold plunge bath to the pool and then to this carbonated spring, a hop, swim, jump route that brings a deep, entirely new kind of healing.
