Yamanashi Yamanakako Village
A sauna with continuously flowing natural underground water and distinctive scenic design, offering 360-degree views of Mt. Fuji and Lake Yamanaka
"CYCL" is a day-use sauna-focused facility that opened on the shores of Lake Yamanaka in April 2024, offering a 360-degree panorama of Mt. Fuji and Lake Yamanaka. Its distinctive, beautifully original circular building, inspired by kasagumo clouds, has no pillars. The sauna features the "Magma Sauna," themed around the deepest part of Mt. Fuji, where guests in swimwear can enjoy conversation together as men and women or in groups. It is equipped with a high-output stove made by Finland's HARVIA, allowing authentic heat through self-löyly. After the sauna, dive into the 120 cm-deep cold plunge bath fed by pristine natural underground water from the Mt. Fuji watershed, flowing at 90 liters per minute and safe to drink, then experience a meltingly blissful state of totonou while feeling the Fujisan downwash. Relaxing in the second-floor observation lounge, where free drinks and sweets are included in the admission fee, feels completely otherworldly.
A genuine mixed-gender sauna, designed to evoke the deepest part of Mt. Fuji, with a striking contrast of jet black and vivid red. Swimwear is required. A high-output stove made by the prestigious Finnish company HARVIA has been installed, and guests can enjoy self-löyly using premium underground water from Mt. Fuji. Powerful heat and a moisture-rich steam fill the room, gently yet intensely warming the skin and promising a refreshingly abundant sweat.
A top-tier cold plunge bath, 120 cm deep (separate areas for men and women), with Mt. Fuji underground natural water gushing at 90 liters per minute and flowing freely without stint. The water temperature stays at about 15-16°C without the need for a chiller. Extremely mineral-rich and soft, the natural underground water cools the body in a mellow, enveloping way without stinging the skin at all, and the water from the tap is delicious and safe to drink. You can immerse yourself in the unparalleled pleasure of melting into the cold stream.
