Relax in an ultra-high-concentration carbonated spring infused with Dead Sea salt and auto-löyly every 30 minutes
Kanagawa Fujisawa City
"Yunoichi Karasawa Branch" is a super sento in Fujisawa, Kanagawa Prefecture, packed with a strong focus on health and beauty. Its biggest highlight is the "Cleopatra Carbonated Spring," which dissolves Dead Sea salt imported directly from Israel into the bath. With one of Japan’s highest concentrations of carbon dioxide at 1250ppm fused with Dead Sea minerals, it is renowned for warming the body remarkably well and leaving the skin smooth. The sauna facilities include two types: a high-temperature tower sauna with auto-löyly every 30 minutes, and an aroma steam salt sauna where you can generously use Dead Sea salt. With a crisp, cold plunge bath and an open-air bathing area for outdoor cooling while looking out over a bamboo grove, it offers everything you need to forget the hustle and bustle of the city and refresh yourself.
