Shizuoka Shizuoka City
Japan's renowned sauna sanctuary
Sauna Shikiji is a sauna facility located in Shikiji, Suruga Ward, Shizuoka City, Shizuoka Prefecture. Known as a sacred site for sauna enthusiasts, its most distinctive feature is the cold plunge bath that uses 100% natural Suruga water. The natural water, filtered from deep underground, is a medium-soft water with hardness 84 and is rich in calcium and magnesium. It is potable and guests are free to take it home. The facility offers two types of herbal saunas in Finnish and Korean styles, and the high-temperature dry sauna follows a Showa-era strong style that induces heavy sweating. The Korean herbal sauna uses authentic medicinal herbs specially blended by Korean herbal doctors. There is also a herbal medicinal bath, a high-mineral natural-water jacuzzi bath, and a dining area on the second floor. Open 24 hours, year-round. About a 15-minute drive from Shizuoka Station, with a large parking lot for 50 cars.
A herbal medicinal bath blended with more than 10 herbs such as matsufuji, plantain, and houttuynia, characterized by a distinctive hinoki-bark color and fragrant aroma. The combination of mineral spring components and herbal ingredients is expected to have benefits for a wide range of conditions, including skin issues, gastrointestinal problems, rheumatism, lower back pain, and stiff shoulders. Its antibacterial, anti-inflammatory, diuretic, and vascular-normalizing properties, among others, can synergize with the sauna to enhance detoxification effects.
A high-mineral jacuzzi bath using the facility's natural spring water. The jacuzzi and jet streams work on pressure points across the body, promoting circulation, relieving fatigue, and easing shoulder and lower back stiffness. It is also introduced as effective for skin beautification and improving sensitivity to cold, functioning as a variation bath to relax the body between intense sauna experiences.
The Finnish sauna, a symbol of this "sauna sanctuary," features dry high heat around 110°C produced by METOS KERKES ceramic stones. There are no water-adding performances or löyly services at all; in the Showa strong style you are simply exposed to intense dry heat to induce deep sweating. With TV background music playing, the simple experience of quietly continuing to sweat captures the hearts of many sauna lovers.
An authentic herbal sauna using medicinal herbs imported from Korea. Normally kept at a modest temperature of about 62°C, the perceived temperature can spike dramatically during high-humidity periods and fever time, producing an intense, nearly wind-wave-like experience. The unique herbal aroma fills the room, and medicinal components such as dong quai, chuanxiong, and peppermint work together with the heat to affect the whole body. The floor can become hot, so take care with your footing.
Uses Suruga natural water filtered from deep underground in a continuous-flow, non-recirculated style. It is essentially a potable cold plunge bath. The water is a mineral-rich medium-soft water with hardness 84. Its texture is extremely gentle—cold yet soft—offering a different, natural taste compared with tap water. The continuous-flow natural water at the back of the cold plunge is drinkable. After the cold plunge, relax and totonou on benches or stools.
