A super sento known for its nano water and high-concentration carbonated spring baths
Shizuoka Shimada City
"Shimada Hourai no Yu" is a super sento in Shimada City, Shizuoka Prefecture, famous for its nano water and high-concentration carbonated spring baths. The "nano water" used throughout the facility is highly absorbent for the skin and leaves you with a moist, refreshing feeling after bathing. The sauna area is also meticulously designed, with a dry sauna that combines an iki stove and a Bona sauna to warm the entire body evenly and encourage a superior sweat. The cold plunge bath uses natural underground water from the Southern Alps, nanoized and supplied as a continuous flow. Combined with the synergy of the "Bihou Toban," where tiny bubbles burst on the surface, you can enjoy an exquisite cooling-down experience that feels as if your whole body is being enveloped.
