Fasting creates the biological conditions for repair. Repeated exposure to mineral-rich thermal water supports that process by calming the nervous system, relaxing muscles and preparing the body for recovery.
The Onsen building sits beside the Spa. You step inside and the temperature changes immediately: warm, humid, quiet. The eight stations move you through a sequence that takes about thirty minutes and feels considerably longer. By the time you reach the mineral hot spring bath and finally the open-air station, the body has been asked, step by step, to release.
The Onsen session happens each day before your massage, Days 1 to 4. By the time you lie down for fifty minutes of bodywork, your muscles have already begun to settle, because each station prepares you for the next.
Beyond the Onsen building, the resort's natural mineral springs flow through the grounds in open channels, warm water at different temperatures, winding through the landscape. Guests move between them in bathing gear, at whatever pace the day allows. The springs are not a treatment, simply part of the setting, always available. That quality, restorative and requiring nothing, is part of what makes this environment so suited to fasting.
Over five days, this daily immersion in thermal water has a measurable effect: cortisol drops, and muscle tension softens over days rather than hours. The nervous system, repeatedly guided back to a resting state, begins to find that state more easily on its own.
