Ramune Onsen 2
The "Ramune Onsen" is a carbonated spring that wraps your entire body in sparkling silver bubbles. These bubbles are caused by the high concentration of carbon dioxide gas in the water. This unique property enhances blood flow, boosts metabolism, raises body temperature, and promotes detoxification. The onsen features two types of natural hot springs: a cooler, 32°C carbonated bath and a warmer, 42°C cloudy bath, both with free-flowing spring water directly from the source. Additionally, showers and a sauna are available for guests to enjoy. Designed by renowned architect Terunobu Fujimori, the black-and-white contrast of the building's exterior is striking. Visitors can also appreciate the charming logo, created by illustrator Shinbo Minami, which adds a playful touch to the experience.
