Saitama Tokorozawa City
"Baden Garden" is a male-only sauna and accommodation facility located in Tokorozawa City, Saitama Prefecture. It features a high-temperature sauna made from 200-year-old kelo wood imported directly from Finland and Japan's first introduced Kalt sauna, perfecting the hot and cold alternating bath experience. The cold plunge bath, filtered through a Binchotan charcoal tower, swiftly cools the body after the sauna, leading to deep relaxation in the outdoor reclining bath or tepid bath. With 96 capsule rooms and 25 private rooms, it also offers a restaurant, view lounge, massage, and esthetic services. This urban complex sauna facility is just a 30-second walk from Tokorozawa Station East Exit and is available 24 hours a day.
An authentic sauna using 'Kelo', a standing deadwood over 200 years old, directly imported from Finland. The high temperature heat envelops the entire body, and every 20 minutes, the automatic löyly spreads heat waves and a unique aroma throughout the room. The distinctive fragrance of the Kelo wood fills the nostrils with every breath, promoting deep sweating.
A cold plunge bath equipped with a Binchotan charcoal tower directly imported from Finland, where tap water is filtered through the Binchotan charcoal.
